Your body can make collagen, but its production decreases with age, environmental exposure, and overuse. As a result, many people have turned to collagen supplements, hoping they can help.
“Collagen [supplementation] may help hydrate skin and improve elasticity,” says Lisa Andrews, RD, founder of Sound Bites Nutrition in Cincinnati.
There is also some growing evidence that collagen supplementation may help slow signs of aging, strengthen nails, and reduce joint pain.
Collagen comes in many forms, including liquid, capsules, and gummies, but powders stand out for their versatility as they are easy to blend into your water, coffee, or smoothies. With so many options, it can be challenging to know which one is right for you — and the best choice isn’t always the one that’s trending on your social media feed.
To help you navigate the noise, we’ve created this guide to the best collagen powders. We reviewed over a dozen top products, assessed their ingredient quality, and consulted registered dietitians to ensure our recommendations are backed by expertise.

When to Consult Your Doctor?
Everyday Health recommends speaking with your doctor before adding any supplement to your diet to ensure it is safe and appropriate for your individual health needs.
While collagen supplements are widely used, if you are pregnant, nursing, managing a health condition, or taking prescription medication, professional guidance is essential. If you have food allergies, it’s also necessary to check the label to ensure a product is safe.
Always consult your doctor to ensure a supplement fits your overall health plan.
Best Unflavored
Vital Proteins Collagen Peptides
Pros
- Flavorless option mixes well into hot and cold liquids
- NSF-certified and third-party tested
- Gluten- and dairy-free
- No artificial sweeteners
Cons
Key Specs
- Best for: Unflavored
- Collagen type: Type 1 and 3
- Collagen per serving: 20 g
- Third-party tested: Yes
Vital Proteins Collagen Peptides is our top choice for a flavorless, versatile collagen supplement. “It’s one of the best collagen supplements on the market,” says Nicole Ibarra, RD. “It’s tested by a third party to ensure it meets strict quality standards. … It’s also certified by the National Sanitation Foundation (NSF), making it a safe choice for athletes,” she adds. NSF certification ensures that the product has been thoroughly tested to confirm its purity and compliance with safety standards.
We love that Vital Proteins Collagen has no flavor and mixes easily into hot and cold liquids without clumping. It’s also dairy and gluten-free. Each serving contains 20 grams (g) of grass-fed, pasture-raised bovine type 1 and 3 collagen peptides (proteins broken down into smaller amino acids for easier digestion and absorption). There are multiple types of collagen in the body, but type 1 collagen is found in skin, hair, nails, joints, and bones, while type 3 collagen is in skin, muscle, and blood vessels and aids in connective tissue health.
It’s important to note that collagen is derived from animal sources (cows in this product), so it isn’t suitable for vegans or vegetarians. However, for those looking for a high-quality, easy-to-add option, Vital Proteins Collagen Peptides is a top choice.
Best for Athletes
Klean Athlete Klean Collagen+C
Pros
- Contains vitamin C to support collagen production
- Mixes easily into liquid
- Gluten-free
Cons
- Not vegan or vegetarian
- Takes longer to dissolve in hot liquids
Key Specs
- Best for: Athletes
- Collagen type: types 1 and 3
- Collagen per serving: 15 g
- Third-party tested: Yes
Klean Collagen+C is a standout choice for athletes and fitness enthusiasts, and recommended by Jenn Schmidt, RD, who is based in Twin Cities, Minnesota. “Klean has 15 g of protein and 50 milligrams (mg) of vitamin C, which, when taken 60 minutes before exercise, is shown to be effective in elevating collagen production,” Schmidt explains.
We like the addition of vitamin C in this formula, since it has some evidence showing it stimulates collagen production in the body.
This product is third-party tested and NSF Certified for Sport, guaranteeing it’s free of harmful ingredients and meets the strict safety standards required for athletic use. It mixes well into beverages (although we noted it takes slightly longer to dissolve in hot liquids). The unflavored option is a good choice for those who prefer not to alter the taste of their drinks, but the berry flavor also provides an alternative for those seeking a touch of sweetness.
It’s important to note that Klean Collagen+C contains bovine-derived collagen, which makes it unsuitable for vegans or vegetarians. We also noticed it took longer to dissolve in hot liquids than some of the other options. Otherwise, if you’re an athlete and want to boost collagen synthesis with a high-quality, scientifically supported supplement, Klean Collagen+ C is a reliable option.
Best Marine-Sourced
Amandean Marine Collagen
Pros
- 10 g of marine-based collagen
- Net-zero plastic footprint
- Made from wild-caught whitefish
- Made in a cGMP-compliant facility
Cons
- Not vegan or vegetarian or for those with fish or seafood allergies
- Some may notice a briny taste
Key Specs
- Best for: Marine-sourced
- Collagen type: Type 1 and 3
- Collagen per serving: 10 g
- Third-party tested: Yes
If you’re looking for an option that isn’t bovine-based, Andrews says marine-based collagen, like Amandean Marine Collagen, is a good alternative. Research suggests that marine-based collagen is just as effective as other collagen sources and is possibly absorbed faster than bovine-based collagen supplements.
Marine-sourced collagen may also help reduce the appearance of wrinkles while improving elasticity, hydration, and firmness.
We like that Amandean Marine Collagen uses wild-caught whitefish (cod, pollock, haddock, and hake) to reduce antibiotic and hormone exposure in the product. The company also donates a percentage of its profits to rePurpose Global to clean up plastic waste, and has removed 20,000 pounds so far. This product is also made in a Current Good Manufacturing Practices (cGMP) facility, which means it adheres to strict quality and safety standards set by the U.S. Food and Drug Administration (FDA).
While the product has a slightly briny taste and smell, mixing it into smoothies or juices helps. It dissolves better in cold than hot liquids, but using an electric whisk helps. Amandean Marine Collagen’s sourcing quality and eco-conscious efforts make it a favorite for those seeking a non-bovine alternative.
Best With Added Probiotics
Garden of Life Grass-Fed Collagen Peptides
Pros
- Added probiotics to support gut health
- Grass-fed, pasture-raised collagen peptides
- Gluten-free
- NSF-Certified
Cons
- Doesn't mix well in cold liquid
- Not vegan or vegetarian
Key Specs
- Best for: Added probiotics
- Collagen type: Type 1 and 3
- Collagen per serving: 20 g
- Third-party tested: Yes
Garden of Life Grass-Fed Collagen Peptides earns a top spot on our list, combining 20 grams of collagen peptides with 1.5 billion colony-forming units (CFU) of probiotics. Along with types 1 and 3 collagen, it includes Lactobacillus plantarum, a probiotic strain that may support immune health, reduce inflammation, and promote a healthy gut microbiome.
Research also suggests that collagen may help alleviate digestive symptoms like bloating, making the blend of collagen and probiotics a potentially powerful duo.
The product’s sourcing — grass-fed, pasture-raised collagen — and its NSF certification further set it apart.
We found the taste neutral and mixed best in hot liquids, but you could also add it to smoothies. We wouldn’t recommend using it in cold liquids without an electric whisk. Overall, Garden of Life offers a quality option if you’re looking for a comprehensive product to support gut health and immunity.
Best Budget-Friendly
Sports Research Collagen Peptides
Pros
- Most affordable option on our list
- Available in multiple flavors
- Non-GMO, gluten-free
- cGMP-compliant
Cons
- Milky flavor in plain water
- Not vegan or vegetarian
Key Specs
- Best for: Budget
- Collagen type: Type 1 and 3
- Collagen per serving: 11 g
- Third-party tested: Yes
Sports Research Collagen Peptides is our top value pick, offering collagen powder at an affordable price of just over $1 per serving. This product contains 11 g of hydrolyzed type 1 and 3 collagen peptides per scoop. Like collagen peptides, hydrolyzed collagen has been broken down into smaller peptides, making them easier to digest and absorb.
This product is NSF-certified, available in multiple flavors, and certified gluten-free. We like its neutral flavor and the fact that it easily mixes into hot beverages like coffee without altering the taste or texture. It also performs well in smoothies, adding beneficial protein without overpowering other ingredients.
It’s worth noting that this product doesn’t mix as well in cold liquids, leaving a thin white film on the top and a mild, milky flavor. Aside from this, the combination of quality, affordability, and effectiveness makes Sports Research Collagen Peptides a solid choice.
Best Grass-Fed
FullWell Unflavored Collagen Peptides
Pros
- Sourced from 100 percent pasture-raised, grass-fed cattle
- Mixes well in hot and cold liquids
- Minimal flavor
- Third-party tested
Cons
- Inconvenient packaging
- Not vegan or vegetarian
Key Specs
- Best for: Grass-fed
- Collagen type: Type 1 and 3
- Collagen per serving: 15 g
- Third-party tested: Yes
FullWell’s Unflavored Collagen Peptides Powder is our top choice for grass-fed collagen because of its commitment to high-quality sourcing and formulation. This powder is derived from 100 percent grass-fed, pasture-raised bovine hides targeted for health-conscious and environmentally mindful consumers.
FullWell, a dietitian-founded brand, was created to bring evidence-based, effective, and high-quality supplements to a broader audience. Their collagen powder delivers 15 grams of type 1 and 3 collagen per serving and dissolves completely in both hot and cold liquids without any gritty residue or clumping. FullWell’s product is third-party tested for ingredient accuracy, heavy metals, and the top 8 allergens (milk, egg, shellfish, fish, tree nuts, peanuts, wheat, and soy).
The only potential drawback of FullWell’s Collagen Peptides Powder is the packaging, which we found could cause spills when first opening. However, given its quality sourcing and sustainable practices, this small downside is a minor trade-off for a grass-fed collagen supplement you can trust.
Best Flavors
1st Phorm Collagen With Dermaval
Pros
- Multiple flavor options
- Tastes good in hot and cold liquids
- Manufactured in cGMP and third-party tested
- Contains additional ingredients for skin health
Cons
- Contains sucralose
- Not vegan or vegetarian
Key Specs
- Best for: Flavor options
- Collagen type: 1, 2, 3, 4, and 5
- Collagen per serving: 15 g
- Third-party tested: Yes
Many of the products on our list are unflavored, but for those who prefer a touch of flavor, 1st Phorm Collagen With Dermaval offers several delicious options like French Vanilla or Salted Caramel that pair perfectly with your morning coffee or smoothie. Dan Gallagher, registered dietitian at Aegle Nutrition, recommends 1st Phorm Collagen With Dermaval because it is produced from five collagen sources (bovine, chicken, fish, and eggs), and the collagen peptides are hydrolyzed, which may be easier for the body to absorb.
This collagen also contains Dermaval, a proprietary blend of beneficial plant-derived ingredients. A small study funded by the makers of Dermaval Dermval found that supplementing with Dermaval Dermavel may promote healthy levels of elastin in the body.
Since elastin helps create firmness and elasticity in the skin, 1st Phorm’s collagen supplement could be particularly beneficial for people wanting to improve their skin health.
While 1st Phorm Collagen is quite sweet, which may not suit all tastes, it blends well in hot and cold liquids. It does contain sucralose, an artificial sweetener that some people may prefer to avoid. However, if you’re looking for a flavored collagen with a bit more sweetness, 1st Phorm has you covered.
Best for Sleep
NativePath Chocolate Collagen PM
Pros
- Contains additional ingredients to support sleep
- No sugar or artificial sweeteners
- Tastes good in hot and cold liquids
- cGMP compliant and third-party tested
Cons
- No unflavored option
- Not vegan or vegetarian
Key Specs
- Best for: Sleep
- Collagen type: 1 and 3
- Collagen per serving: 10 g
- Third-party tested: Yes
For a product that provides the potential benefits of collagen and may help you sleep better, NativePath’s Collagen PM wins. This product contains sleep-promoting ingredients, including magnesium, which may support relaxation, L-theanine (a natural ingredient in green tea that helps with stress), and melatonin to promote a calm and restful sleep.
It’s also formulated with gamma-aminobutyric acid (GABA), a chemical messenger that plays a role in reducing stress. When combined with L-theanine, GABA may help improve sleep quality and duration.
Keep in mind that this product contains 5 mg of melatonin, which may cause grogginess for some people. If you plan on taking NativePath Collagen PM long-term, it’s essential to discuss it with your doctor first to ensure it’s the right fit for you.
NativePath Collagen PM’s chocolate flavor tastes like lightly sweetened hot cocoa, thanks to monk fruit extract. For best results in cold or room-temperature liquids, use a blender or electric whisk. With flavors like chocolate, honey chamomile, and lemon, it’s a sweet and soothing nightcap, though the lack of an unflavored option may be a drawback for some.
Best for Pregnancy
Needed Prenatal Collagen Protein
Pros
- Sourced from grass-fed, pasture-raised bovine collagen
- Third-party tested and minimal ingredient list
- Unflavored and easy to add to beverages
Cons
- Studies on collagen and pregnancy are limited
- Not vegan or vegetarian
Key Specs
- Best for: Pregnancy
- Collagen type: 1 and 3
- Collagen per serving: 15 g
- Third-party tested: Yes
Many of the collagen options on our list would work during pregnancy, but we selected Needed Prenatal Collagen Plus for its exceptional quality standards and dedicated focus on supporting pregnancy and postpartum needs. “Needed Prenatal Collagen is third-party tested, using only grass-fed bovine collagen with no additives, highlighting their commitment to simple and high-quality ingredients,” shares Kaytee Hadley, RDN, functional medicine dietitian and founder of Holistic Health and Wellness in Richmond, Virginia.
Collagen contains glycine, an amino acid essential for collagen synthesis and crucial for growth, healing, and repair, especially during the later stages of pregnancy.
This supplement also provides an easy way to increase protein intake, which is critical for fetal growth, placental health, and reducing complications like gestational diabetes or preeclampsia — although it’s important to note that collagen is not a complete protein, which means you need to make sure you’re getting protein from other sources as well.
Hadley cautions that supplementing with any product during pregnancy should warrant a conversation with your doctor, as there is limited research specifically on collagen supplementation during pregnancy. Once you get the okay from your doctor, Needed Prenatal Collagen Protein is a standout option for pregnant individuals seeking safe and effective collagen supplementation.
Best for Skin Health
Thorne Collagen Plus
Pros
- Contains types 1 and 3 collagen to support skin elasticity and firmness
- Includes additional skin-supportive ingredients
- Third-party tested and NSF-certified
Cons
- Priciest on our list
- Not vegan or vegetarian
Key Specs
- Best for: Skin health
- Collagen type: Type 1 and 3
- Collagen per serving: 13 g
- Third-party tested: Yes
Thorne Collagen Plus earns its title as the best collagen for skin health thanks to its evidence-supported ingredients. Collagen supports your skin health by maintaining the structure necessary for elasticity, so as production drops, signs of aging like sagging and wrinkles can increase.
“Thorne Collagen Plus may be one of the best collagen formulas I’ve seen to support skin health,” shares Hadley. “This science-based combination may support the skin in a number of ways including hydration, fine lines and wrinkles, reduced skin pigmentation, and improved texture.”Collagen supplements may support healthy skin by providing the amino acids necessary for collagen synthesis and may help to replace damaged skin fibers.
In addition to collagen, this Thorne product is formulated with other skin-supportive ingredients like HydroPeach, which contains lipid molecules called ceramides that may help maintain moisture in the skin.
Thorne Collagen Plus is also made with mitoHeal, a special blend of polyphenols, which are natural compounds found in plants known for their antioxidant benefits. These antioxidants may help protect your skin by fighting oxidative stress — a key factor in aging.
While Thorne Collagen Plus is undeniably high in quality, its complex formula reflects a higher price point compared with more basic collagen powders. Still, the unique and potent ingredients may justify this premium cost.

Best for Joint Health
NOW Foods Multi Collagen Protein
Pros
- Multi-source collagen for joints, cartilage, and connective tissue
- Added vitamin C for collagen production.
- Gluten-free
- Mixes easily into drinks
Cons
- Noticeable taste for some
- Not vegan or vegetarian
Key Specs
- Best for: Joint health
- Collagen type: 1, 2, and 3
- Collagen per serving: 11 g
- Third-party tested: Yes
With multiple sources of collagen, NOW Multi Collagen Protein combines type 1 and 3 collagen from beef, type 2 collagen from chicken bone broth, and type 1 collagen from fish for a comprehensive joint supplement. Andrews likes that this formula provides a versatile approach to supporting joint cartilage, connective tissue, and overall functionality. Vitamin C adds additional support to promote joint recovery and collagen synthesis.
Type 2 collagen plays a key role in maintaining the structural integrity of cartilage and synovial fluid — elements essential for cushioning and smooth joint movement.
Studies suggest that supplementing with collagen, particularly type 2, may reduce joint pain and improve daily activities. For instance, taking 10 to 20 g of collagen consistently for several months has been shown to improve joint function and help alleviate discomfort.
Andrews adds that combining collagen supplementation with regular exercise may further enhance its effects to help reduce joint pain and increase collagen synthesis in joints.
NOW Multi Collagen Protein is an evidence-informed option worth trying if you have occasional stiffness and discomfort. This gluten-free supplement is easy to mix into drinks or smoothies, however, it’s worth noting that some testers noted they could taste the collagen.
Best for Hydration
Perelel Cellular Hydration Powder Boost
Pros
- Supports both hydration and skin health
- Contains Hyaluronic acid for hydration and elasticity
- Triple tested for safety, purity, and quality
- Sugar-free
Cons
- Lower collagen dose compared with others on this list
- Not vegan or vegetarian
Key Specs
- Best for: Postpartum hydration and skin health
- Collagen type: Type 1 and 3
- Collagen per serving: 3.5 g
- Third-party tested: Yes
Perelel Cellular Hydration Powder offers a double-duty formula that provides electrolytes like magnesium and potassium for repletion with ingredients for skin health. While advertised as a supplement for postpartum hydration support, this sugar-free powder can benefit anyone.
Beyond supporting hydration, which is especially helpful postpartum, the added collagen and hyaluronic acid may promote skin elasticity and hydration. Hyaluronic acid is a molecule known for holding water in the skin.
Andrews points to a meta-analysis published in that found taking collagen supplements — anywhere from 2.5 to 10 g daily — for 8 to 24 weeks can improve skin elasticity and hydration.
Perelel Hydration Powder is sweetened with monk fruit, free from additives, and undergoes triple testing for safety, purity, and quality. It’s important to note that since this product is designed primarily to support hydration, the collagen dosing per serving of 3.5 g is lower than most standalone collagen powders (although in the meta-analysis above, doses as little as 2.5 g showed benefit).
But for those seeking a multifunctional approach to postpartum recovery and hydration, Perelel offers an impressive product.

How We Reviewed the Best Collagen Powders
Our review process for the best collagen supplements includes a combination of expert recommendations and hands-on testing. To create this list, we consulted five registered dietitians, including:
- Lisa Andrews, RD
- Nicole Ibarra, RD
- Jenn Schmidt, RDN
- Dan Gallagher, RD
- Kaytee Hadley, RDN
We also used the collagen in our own kitchens to evaluate how these supplements perform in everyday scenarios. From mixing a scoop into coffee, adding to smoothies, or stirring collagen into water, we examined critical factors like mixability, flavor, and texture.
As a registered dietitian, I bring both professional expertise and personal experience to the table. Since I use collagen daily as part of my routine, I’m able to critically evaluate these products from multiple angles — focusing not just on quality but also on whether they’re tasty and easy enough to become a part of your everyday routine.
What Are the Benefits of Collagen?
Collagen supplements show promise in supporting various aspects of health, with research indicating benefits for hair and nail strength, skin appearance, joint health, and bone density.
Studies suggest that collagen may enhance hair thickness and nail growth while reducing brittleness, with noticeable results seen after consistent use for 12 to 24 weeks.
Similarly, collagen may support skin elasticity, moisturization, and wrinkle reduction.
Collagen may also support joint health and improve mobility. A review published in found that collagen supplementation reduced joint pain and enhanced joint function, particularly when combined with exercise programs.
Studies in postmenopausal women also reported increased bone mineral density after a year of daily collagen supplementation, highlighting its potential in addressing age-related bone loss.
Who Should Not Take Collagen
“Collagen isn’t for everyone,” shares Hadley. “Individuals with autoimmune conditions such as lupus and rheumatoid arthritis should be cautious about taking collagen supplements because it may worsen symptoms by causing the immune system to become overactive.”
Collagen supplements also may not be suitable for those with allergies and dietary restrictions as they can contain ingredients derived from fish, eggs, pigs, or cows. Additionally, some supplements are processed in facilities that handle dairy or gluten.
Finally, if you need to limit protein intake, such as for those with kidney disease, or if you are pregnant, breastfeeding, or taking any prescription medications, check with your doctor before adding collagen supplements.
FAQs
What is the most effective collagen to take? The best collagen supplement depends on your needs. Most collagen supplements contain types1 and 3 for general wellness and skin, joint, and muscle health. Type 2 collagen is often found in joint-health specific products.
Do collagen supplements really work? There is never a 100 percent guarantee behind supplements. Each person is unique and may respond differently to supplements. Research suggests supplements may benefit skin, joint, and nail health, but individual results can vary.
Can I take collagen every day? Yes, in general, it’s likely okay to take a collagen supplement every day. Follow the instructions on the packaging for the correct serving size. If your collagen supplement contains additional ingredients, speak with your doctor before taking the supplement every day.
How much collagen should I take? Studies have found that taking collagen doses of 2.5 to 15 g a day may be safe and effective, depending on your health goal.
What are the different forms of collagen? The body contains various types of collagen, according to StatPearls, but supplements typically feature types 1, 2, 3, and 4.

Marine collagen has become a highly sought-after dietary supplement , particularly in the field of sports nutrition. Appreciated for its benefits on the health of the skin , joints and connective tissues , it appeals to many fitness and bodybuilding enthusiasts.
However, despite its success, it is essential to consider the potential dangers associated with its consumption. Here, we will analyze the risks associated with taking marine collagen and the precautions you need to take for safe use.
What is marine collagen?
Marine collagen is a protein extracted from the skin, scales or bones of fish such as salmon, pollock and tilapia. It is usually hydrolyzed to make it easier for the body to absorb.
Its similar structure to human collagen makes it an effective supplement to support the health of connective tissues, including the skin and joints.
The potential risks of marine collagen
Fish allergies
One of the main concerns about consuming marine collagen is the risk of allergies. People who are allergic to fish may develop allergic reactions when consuming this type of collagen. Symptoms may include itching, rashes, swelling, or even difficulty breathing. It is essential for anyone with a seafood allergy to consult a healthcare professional before considering taking marine collagen .
Keep in mind that even without a known allergy, some people may develop a sensitivity or intolerance to marine collagen, manifested by digestive disorders such as nausea, bloating, or diarrhea. We recommend starting with a small dose and observing how your body reacts before increasing the amount consumed.
Heavy metal contamination
Heavy metal contamination, such as mercury, lead, or arsenic, is another major concern. These metals can accumulate in fish tissues due to water pollution. If collagen is extracted from fish from polluted areas, it may contain dangerous levels of these substances. Regular consumption of contaminated marine collagen can have long-term adverse health effects, including damage to the nervous system, liver, and kidneys. To minimize this risk, it is important to choose products that come from reliable sources and are tested for purity.
It is important to note that European regulations impose strict limits on the levels of heavy metals in dietary supplements. However, not all products always meet these standards, making it essential to check for quality certifications when purchasing marine collagen.
Drug interactions
Marine collagen may interact with some medications, particularly blood thinners. Collagen contains amino acids that can potentially increase blood clotting, which could interfere with medications intended to reduce the risk of blood clots. People taking medications, particularly for cardiovascular conditions, should consult their doctor before incorporating marine collagen into their routine.
In addition to blood thinners, marine collagen may interact with other medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and some blood pressure medications. It is therefore essential to discuss with a healthcare professional to avoid any unwanted interactions.
Risks of overdose
Although marine collagen is generally well tolerated, excessive consumption can lead to unwanted side effects. An overdose of protein, including collagen, can overload the kidneys, especially in people with already compromised kidney function. Additionally, excess collagen can cause digestive upsets such as bloating, constipation, or diarrhea.
Another risk associated with overdose is hypercalcemia, a condition where calcium levels in the blood are too high. Although rare, this condition can occur if marine collagen is consumed in large amounts over a long period of time, especially if calcium supplements are also taken. Symptoms of hypercalcemia include nausea, vomiting, muscle weakness, and mental confusion.
Precautions to take
Choosing a quality product
The quality of the health food supplement "Marine Collagen" depends largely on the source of the fish and the manufacturing methods used. Opt for products from recognized brands that carry out rigorous testing of their raw materials. Make sure that the collagen comes from wild or sustainably farmed fish and that it is free of contaminants.
Also look for certifications like the Marine Stewardship Council (MSC) label, which ensures that the collagen is sourced sustainably and environmentally friendly. Products with the Good Manufacturing Practices (GMP) label are also recommended, as they indicate that the manufacturer follows strict manufacturing practices to ensure product quality and safety.
Consult a health professional
Before you start taking marine collagen, we advise you to consult a healthcare professional , especially if you have a medical history, are taking medications or are prone to food allergies. A medical opinion will help you determine if marine collagen is suitable for your situation and what dose would be most appropriate.
Pregnant or breastfeeding women should especially consult their doctor before taking marine collagen supplements, as the safety of this supplement during pregnancy is not fully established.
Follow dosage recommendations
Respecting the doses recommended by the manufacturer is essential to avoid side effects related to excessive consumption. Generally, a daily dose of 2.5 to 10 grams of marine collagen is considered safe and effective.
If adverse symptoms occur, reduce the dose or stop taking the supplement and consult your doctor.
Marine collagen is a great ally to support the health of your skin, joints and connective tissues. However, as with any dietary supplement , it is important to be aware of its potential risks and take all necessary precautions to ensure safe use.
