Health / David Hattan Collagen is the most abundant protein in your body and provides structure for skin, hair, nails, joints, cartilage, and bones. Since collagen production naturally declines as we age, collagen supplements are often marketed with anti-aging claims. According to Kelsey Kunik, RDN, some health claims on collagen may be far-fetched in terms of what it can do for making you feel and look younger. Kunik suggests collagen’s greatest benefits are for improving skin hydration and elasticity, and possibly helping improve joint stiffness. The bottom line is research on collagen supplements is not always consistent, and we still have a lot to learn. Some people may not benefit from collagen as long as you consume the building blocks of collagen—adequate protein, vitamin C, zinc, and copper. Collagen supplements may also be helpful to active people with joint pain or those looking to up their protein intake. However, collagen does lack some essential amino acids, so it shouldn’t be the primary source of protein in your diet. There are 28 different types of collagen in the body, with type I through IV making up 90 percent of the collagen. Types I, II, and III are the most studied and the types most commonly found in supplements. Currently, all supplements come from animal sources, so collagen supplements are not appropriate for vegans. When choosing the best collagen supplements, our team of registered dietitians researches dozens of supplements and considered recommendations from other registered dietitians including those that work with women in menopause and during pregnancy. When choosing the best supplement for you, you’ll want to evaluate the type of collagen, form (pill, powder, liquid, or gummy), dose, other ingredients in the supplement, and third party testing. A Note About Supplements Dietary supplements are minimally regulated by the FDA and may or may not be suitable for you. They also may interact with other supplements or medications you are taking. Our team of registered dietitians reviews supplements according to our rigorous dietary supplement methodology. We also had a registered dietitian review this page for its scientific accuracy. Please always speak with a healthcare provider to discuss any supplements you plan on taking.

It’s Worth Noting: While it provides all three types of collagen, it is lower in protein than some other powders available on the market. It is also not safe for those with fish allergies. Now Multi Collagen Protein Types I,II, and III checks nearly all of the boxes we look for in a quality collagen supplement. It contains types I and III collagen, which may support skin and nails, as well as type II for joint and bone support. The collagen comes from a mix of cow, chicken, and fish, so it is not suitable for vegans or those with a fish allergy. It also contains vitamin C which helps support collagen production. One serving, which is 2.5 tablespoons, contains 10 grams of protein (11 grams of collagen) and just over 100 percent of your daily vitamin C needs. Because it’s unflavored, you can add it to any food or beverage you like—coffee, tea, oatmeal, smoothies, baked goods and more.

With 18 grams of protein from grass-fed, pasture-raised cows per serving, it’s an easy way to add protein to your day—especially since it can be added to warm or cool beverages. It contains types I and III collagen which have been shown to support skin, hair, and nail health. It does not contain type II collagen, which is the type of collagen that may help support joint health. However, keep in mind the most important thing for collagen production is to consume adequate protein, vitamin C, zinc, and copper. In addition to the traditional tub, you can also purchase single-serve packets which are a convenient option if you’re on-the-go or traveling. Of note, the single-serve packets only provide 10 grams of collagen peptides. We like that this pick is NSF Certified for Sport, a rigorous third-party organization that tests for harmful contaminants as well as banned substances by sport. It’s also gluten-free, nut-free, soy-free, and Non-GMO.

It’s Worth Noting: There’s only one flavor (orange mango), and it does contain a small amount of added sugar. Momentous Collagen Shot is one of the most convenient ways to take collagen. It comes as an individually packaged liquid shot that you can drink on-the-go, making it a great option for active people who want to add collagen to their workout routine. Small studies suggest that collagen may help reduce joint pain in otherwise healthy active young people. With 10 grams of collagen per serving, it’s also an easy way for athletes to consume protein before or post-workout which may support recovery when paired with some carbohydrates. Momentous recommends to take two shots 30-60 minutes before exercise to help support collagen synthesis or one shot per day if not exercising. We like that this easy to take collagen source contains about 40 percent of your daily vitamin C needs. This can be helpful because vitamin C can support collagen production in the body. It’s NSF Certified for Sport, which means that it’s been tested to confirm that what’s inside is what’s on the label, and it doesn’t contain any harmful contaminants or substances banned by sport. The Momentous Collagen Shot currently only comes in one flavor—orange mango. It contains three grams of added sugar as well as sucralose, a low-calorie sweetener.

It’s also NSF Contents Certified and NSF Certified for Sport. It’s Worth Noting: With the added zinc, copper, and vitamin C, you’ll want to consider any other supplements you’re taking to ensure you’re not exceeding the tolerable upper level intake (UL) for these nutrients. Gnarly Collagen Pro is a solid choice for anyone looking to up their protein intake with ease. Since it’s unflavored, you can add it to any hot or cool liquid of choice, or it can be mixed into oatmeal, yogurt, or even added to baked goods. It contains all of the building blocks your body needs to support collagen production—amino acids from the collagen peptides, vitamin C, zinc, and copper. With 14 grams of protein per serving, it’s also an excellent supplement to boost your protein intake. Because it contains additional vitamins and minerals, you will want to consider any other supplements you take such as a multivitamin to ensure you’re not exceeding the tolerable upper intake levels (UL) for any of these nutrients. It’s also important to know zinc may also interact with certain medications such as antibiotics, diuretics, and Penicillamine, a medication used to treat rheumatoid arthritis. Gnarly Pro Collagen is both NSF Contents Certified and NSF Certified for Sport, two rigorous certifications that ensure that what’s in the package is what you see on the label, and it doesn’t contain any harmful contaminants or substances banned by sport.

It's also NSF Certified for Sport. It’s Worth Noting: While it doesn’t contain any added sugars, it is sweetened with stevia, a low-calorie sweetener. A top brand for collagen powders, Vital Proteins makes a delicious chocolate powder that contains 20 grams of collagen from grass-fed cows. With 18 grams of protein, it’s not only a good option for adding collagen to your routine, it can also help you up your protein intake. Powders like this one also make it easy for you to adjust your serving size to meet your individual needs. It’s a favorite of Pam Hartnett MPH, RDN, owner of The Vitality Dietitians, who appreciates that it’s made from pasture-raised cows and easy to add to any hot or cold beverages. She does note that a milk frother or small whisk can be helpful for blending it into cold drinks. More things we appreciate about Vital Proteins Chocolate Collagen Powder is it contains 3 milligrams of iron and is made without dairy or gluten. It’s sweetened with stevia, a low-calorie sweetener that is generally recognized as safe (GRAS), though some people don’t love the taste of it or prefer to avoid it.

The Best Protein Shakes of 2023 Best Capsule Youtheory Collagen with Vitamin C Amazon View On Amazon View On Youtheory.com Why We Like It: Youtheory Collagen Advanced contains a higher amount of collagen than most capsules and has three types of collagen. It’s also third-party tested. It’s Worth Noting: While it does contain a higher dose of collagen than most capsule supplements, you do need to take six capsules to get the full dose. The capsules also are quite large to swallow. If you prefer to take your collagen in pill form, Youtheory Collagen Advanced may be a good option for you. Each capsule contains one gram of collagen, and a full recommended serving size (six capsules) contains six grams plus 100 percent of your daily vitamin C needs. Most research on collagen supplements suggests that between five to 15 grams is an adequate dose, which is actually difficult to find in capsule or pill form. It’s third-party tested for heavy metals and other contaminants as well as to confirm that the capsules actually contain the amount that’s listed on the supplement facts panel. It is also significantly less expensive than most powders. Lastly, it’s worth noting that unlike powders, capsules are not a meaningful source of protein.

Best for Joints Momentous Collagen Peptides 4.2 Amazon View On Amazon View On Livemomentous.com Why We Like It: In addition to bovine collagen, Momentous Collagen Peptides contains FORTIGEL, a type of collagen peptide that has been shown to support joint health. It's also NSF Certified for Sport. It’s Worth Noting: This powder is more expensive than many of the other powders on the market. Momentous Collagen Peptides are designed specifically for those looking to improve joint health, which could be a good choice for active people. It contains a mix of types I, II, and III of bovine sourced collagen as well as FORTIGEL—a type of collagen peptide that may stimulate collagen production in tendons and reduce knee and joint pain in otherwise healthy people. Because it’s NSF Certified for Sport, it’s also a good option for competitive athletes. This powder can help you boost protein intake, as there is 15 grams of protein per serving. Since it’s unflavored, you can add it to any drink or food you’d like without changing the taste. It contains around 50 percent of your daily vitamin C needs which can also help stimulate collagen production. Momentous Collagen Peptides are pricier than many of the other powders on the market, so it’s worth considering whether or not you think you need the addition of the FORTIGEL in your powder.

It’s also less expensive than powders and is third-party tested. It’s Worth Noting: It’s not a good source of protein, and in order to get a full dose you need to take four capsules. One of the top reasons some people reach for collagen supplements is to help reduce wrinkles. TruNature Healthy Skin Verisol Collagen contains a specific type of collagen—known as Verisol—that has been shown to reduce eye wrinkles. It’s also a simple supplement with just 2.5 grams of collagen peptides, 15 milligrams (<1 percent of the RDA) of sodium, and nothing else. We also like that it’s third-party tested for ingredient amounts, contaminants, and that it comes at a relatively reasonable price point for collagen supplements. While most studies use higher doses of collagen (five to 15 grams), this particular form has been studied at lower doses of 2.5 grams which makes it a reasonable option to take in pill form. However, because of this, it’s not a good option for people looking to increase their protein intake from collagen supplements. Price at time of publication: $19 ($0.32 per serving) Product Details Form: capsuleServing Size: 4 capsules Sugar: 0 gramsProtein per serving: 2 grams Collagen per serving: 2.5gCollagen Source: VERISOLOther ingredients: none Best Creamer Garden of Life Collagen Creamer Amazon View On Amazon View On Gardenoflife.com Why We Like It: It’s a tasty dairy-free creamer that adds 10 grams of collagen to your coffee. Garden of Life is also a reputable supplement company that’s known for quality products. It’s Worth Noting: It’s sweetened with stevia and contains some probiotics, which may not be suitable for everyone. It’s also relatively high in calories. If you’re looking for a collagen designed specifically to add a touch of sweetness and cream to your coffee, we recommend Garden of Life Collagen Creamer. With 10 grams of collagen (9 grams of protein) per scoop, it’s an easy and delicious way to get your dose of collagen as you start your day. It’s a dairy-free and gluten-free option that is available in both chocolate and vanilla flavors. In addition to collagen, it contains medium chain triglyceride (MCT) oil from coconut, which is what makes this creamer creamy and satisfying. There are a few added ingredients worth noting that aren’t in most other collagen powders including added fiber and probiotics. These are likely safe for most people, but anyone with digestive issues may want to avoid (or at least discuss with your healthcare provider before trying). While it doesn’t contain any added sugar, it is sweetened with stevia. With 140 calories per scoop, it’s higher in calories than most other collagen powders. The calories come mostly from the protein and the MCT oil as well as a small amount of carbohydrates.

It’s Worth Noting: It’s lower in collagen and protein than most other powders, and it is not safe for someone with a fish allergy. If you’re pescatarian or prefer to avoid products made from cows or chickens (the two most common sources of collagen), ProCaps Marine Collagen Peptides may be a good option for you. It contains five grams of collagen per serving that is derived from tilapia. This is on the lower end of collagen powders and doesn’t add a significant amount of protein to your day. This may be something to be aware of if you’re relying on collagen powders for added protein. However, five grams is still within the range that had been shown in the research to be effective at improving skin elasticity and other possible benefits. It’s third party tested and contains just one ingredient—collagen peptides. It’s unflavored (don't worry, it doesn’t taste like fish) so it can be added to any food or beverage you’d like. Price at time of publication: $55 ($0.92 per serving) Product Details Form: powderServing Size: 1 scoop (5g)Sugar: 0 gramsProtein per serving: 5 gramsCollagen per serving: 5 gramsCollagen Source: fish (tilapia)Other ingredients: none Who May Not Want to Use Collagen Supplements Collagen is safe for most adults, though it may not necessarily be helpful for everyone. “If you don't have a reason for taking a supplement, it's best to leave it on the shelf,” says Sarah Pflugradt, MS, RDN, CSCS. Collagen supplements may not be appropriate for the following groups of people: People Who May Need to Limit Protein in Their Diet “Collagen is a pretty low-risk supplement, but since it does contain protein, people who need to monitor protein intake, like those with chronic kidney disease, should be cautious of this supplement,” says Kunik. People with Certain Food Allergies Some collagen supplements contain allergens including egg or fish, so if you are allergic to either of those ingredients, you’ll want to look for products that don’t don’t contain collagen from those sources. In addition, not all collagen supplements are gluten-free, so if you need to avoid gluten, be sure to choose a product that is certified gluten-free. Vegans or Vegetarians Collagen supplements are made from animal or marine sources, which means they would not be appropriate for someone who avoids those foods. “Currently there are vegan based supplements that help to boost collagen production, but they are not a direct source of collagen peptides,” says Jamie Adams, MS, RDN, women’s health nutrition expert and owner of Mamaste Nutrition. Who May Want Collagen Supplements If you’re looking to support skin elasticity, nail strength, joint health, and bone density, collagen supplements may be a helpful addition to your routine. However, it can be helpful to understand that your body “doesn’t directly absorb collagen to be used by your skin, bones, and joints, " says Adams. Instead, your body will break down the collagen into amino acids, which are the building blocks of all proteins. These amino acids may be used along with vitamin C, zinc, and copper to produce collagen as well as other proteins that the body needs. The most important thing to consider for collagen production is that you’re consuming enough protein, vitamins, and minerals to support collagen production. Supplements may be one way to ensure that you’re getting those nutrients. One note is that studies on collagen supplements are small, short-term, and conducted among post menopausal women or young, healthy athletes, so keep in mind some study results may not apply to you. People Who Don’t Consume Adequate Protein Collagen powders in particular can be a helpful way to boost your protein intake if you have trouble getting enough through your diet or have elevated protein needs. On the higher side, some collagen supplements can provide 15-20 grams of protein per serving. People Looking to Improve Skin Elasticity or Reduce Wrinkles Collagen has long been used in skincare and supplements are marketed as a way to improve skin appearance due to its role in skin elasticity. Some studies have shown that collagen supplements can improve elasticity and reduce wrinkles. Much of the research in this area has focused on older women, especially those that experience damage from a lot of sun exposure. People with Joint Pain Collagen supplements have been studied in both young, healthy athletes as well as older people with osteoarthritis, with some promising results. There may be more benefits from type II collagen, the type found in cartilage (and is usually in the form of chicken cartilage in supplements), though more research is needed. Post Menopausal Women “As women approach menopause they may experience a significant drop in collagen levels, resulting in saggy skin, achy joints, and a decrease in bone mineral density. Collagen supplementation may help alleviate these symptoms,” says Hartnett. Bone density can decline after menopause due to changes in hormones. One small study showed that taking five grams of collagen peptides per day for a year increased bone density in postmenopausal women. However, more research is needed to confirm benefits of collagen in postmenopausal women. Pregnant and Breastfeeding Women Protein needs are higher during pregnancy, and collagen supplements can be one way to help meet those increased needs. “Collagen peptides may help with skin elasticity as a pregnant woman's belly stretches and grows,” says Adams. Athletes “One of the most specific, but less talked about populations that can benefit from collagen supplementation is athletes. Collagen has been studied for its role in injury prevention and rehabilitation for young and older athletes alike. Collagen synthesis has been shown to increase with collagen supplementation. For a population like this, the recommendations are very specific. To improve collagen synthesis in the targeted areas, it is recommended to supplement with collagen one hour before activity and include a source of vitamin C,” says Pflugradt. Our Approach to Supplements Our team works hard to be transparent about why we recommend certain supplements. We support supplements that are evidence-based and rooted in science. We value certain product attributes that we find to be associated with the highest quality products. We prioritize products that are third-party tested and certified by one of three independent, third party certifiers: USP, NSF, or ConsumerLab.com. It's important to note that the FDA does not review dietary supplements for safety and effectiveness before they go to market. Our team of experts has created a detailed, science-backed methodology to choose the supplements we recommend. Experts we spoke to for choosing the best collagen supplements include: Pam Hartnett MPH, RDN, owner of The Vitality Dietitians gave personal recommendations for collagen powders she uses and the safety of these supplements. Kelsey Kunik RDN, intuitive eating dietitian helped clear up what collagen supplements may or may not help with. Sarah Pflugradt, MS, RDN, CSCS, dietitian and author explained who may or may not benefit from collagen supplements. Jamie Adams, MS, RDN, women’s health nutrition expert and owner of Mamaste Nutrition gave insight into how the body uses collagen and who may most benefit from collagen supplements. Shannon A. Garcia, MDS, RD, LD with KISS in the Kitchen provided tips for safety of collagen and what to look for in supplements. What to Know About Collagen Supplements Potency & Purity Testing Supplements that are third-party tested are sent to a lab where they are tested to ensure they contain what they say they contain and are not contaminated with specific high-risk, common contaminants. However, it’s important to note: Third party testing does not test to see if a product is effective or safe for everyone, and it does not ensure the supplement will not interact with other supplements or medications.Not all third-party testing is created equal. It is not uncommon for supplement companies to pay labs for certificates after conducting minimal to no testing. The third party certifications we can trust are: ConsumerLab.com, NSF, and USP. However, these certifications are difficult to obtain and/or expensive for manufacturers, so many companies choose not to get their products tested by one of these three organizations. Sometimes products tested by these three companies are more expensive to try to offset the cost they pay for certification.Just because a supplement is not tested by one of these three companies, it does not mean it’s a bad product. We recommend doing some research on the reputability of the manufacturer, and calling up the manufacturer and their testing lab to determine their protocols and decide if you feel comfortable consuming the supplement. We recommend selecting products from brands that are transparent about their values, formulations, and manufacturing processes. Form Collagen supplements are available in powders, liquid, gummies, and capsules. The best form will depend on your individual preferences and goals. Powders tend to offer larger doses than capsules and gummies, though they may be less convenient as they have to be added to food or beverage. Powders, liquids, and gummies may come along with added sugar or alternative sweeteners, so you’ll want to be mindful of those ingredients if you have strong preferences. Ultimately, the best form of collagen is the one that works for you and your lifestyle. Ingredients: What to Pay Attention to It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included, relative to the recommended daily value of that ingredient. Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking. Vitamin C. Vitamin C is commonly added to collagen supplements for enhanced absorption. This water soluble vitamin is generally safe for most people. However, too much vitamin C can lead to side effects including nausea, vomiting, and diarrhea, so be mindful about using collagen powders along with other vitamin C supplements or multivitamins. The Tolerable Upper Intake Levels (UL) for vitamin C is 2,000 mg per day for adults. Zinc. Some collagen supplements also contain zinc. Too much zinc (more than 40 mg) in supplement form can lead to nausea, vomiting, and diarrhea, so pay attention to how much you’re taking from supplements. Zinc may also interact with certain medications so if you’re considering a collagen supplement that contains zinc, check with your healthcare provider to ensure it’s safe for you. Digestive enzymes and probiotics. Some collagen supplements also contain digestive enzymes. In general digestive enzymes provide no benefit to healthy people, and probiotics may or may not offer benefits. Both of these may lead to digestive side effects in some people, so it may be something to avoid unless your healthcare provider recommends you take them. Collagen Dosage Since you don’t need to consume collagen through food (your body can make it as long as you consume adequate protein, vitamin C, zinc, and copper), there isn’t an established dose. Most studies that test the benefits of collagen use between five to 15 grams of collagen peptides or hydrolyzed collagen daily for eight to 12 weeks (though some are shorter or longer). One exception is Verisol, a specific type of collagen peptide that has been shown to have some skin benefits at doses as low as 2.5 grams. The right dose for you depends on your goals as well as your current diet. “Lower amounts are used for skin support while closer to 10-15 grams per day is used to support bone and joint health,” says Kunik. How Much is Too Much? Collagen supplements are generally well tolerated by most people and there is no established tolerable upper intake level. “A normal serving size (one to two scoops per day) is safe and offers a variety of amino acids that complement other sources of protein in the diet,” says Shannon A. Garcia, MDS, RD, LD with KISS in the Kitchen. But you’ll want to think about how collagen supplements fit into your overall protein intake. Collagen supplements aren’t a good source of the amino acid tryptophan, which is an essential amino acid you need to consume because your body can’t make it. One recent study suggests that consuming up to 36 percent of your protein from collagen peptides is safe while still allowing for enough other protein in your diet to ensure you’re getting all of the essential amino acids to stay healthy. Your Questions, Answered Is it ok to take collagen everyday? Collagen is safe to take daily. “It's not something that builds up in the body. It is a protein that will break down and add to your body's pool of amino acids,” says Pflugradt In fact, taking it sporadically may not lead to any of the potential benefits. “Most studies that found a benefit to collagen supplementation looked at consistent daily intake, and none of these studies found significant side effects,” says Hartnett. How long does it take for collagen supplements to work? “There are many factors that play a role in the effectiveness of taking collagen supplements,” says Adams. The form, type of collagen, dose, and your individual health and dietary status all can play a role in how long it may take to see potential benefits. “Most studies see skin and joint benefits after taking collagen supplements for 3-4 months. Whereas studies looking at bone health don’t see the benefits until after 12 months of use,” says Adams. Most studies that see these benefits do require daily use for this time period. Are collagen supplements good for hair? Collagen supplements are often recommended for hair growth because collagen has many of the amino acids found in keratin, which is the primary protein found in hair. One very small study showed that 12 weeks of collagen supplements led to women experiencing less breakage. They also reported that their hair appear thicker. More research is needed to support this theory. (17) What is the best form of collagen to take? The best form of collagen is the one that you will take consistently. However, Garcia recommends powders because it’s easier to get adequate amounts of collagen without unnecessary extras. “Liquids often contain other questionable ingredients or proprietary blends that don’t disclose the amounts of ingredients and gummies can only fit a small amount of collagen,” she notes. Capsules also often have lower collagen amounts, you need to take multiple pills, and many contain additional ingredients that you may not need. Are collagen supplements worth it? The research supporting the benefits of collagen supplements is limited and inconsistent. In general, studies have been small, short-term, and are often done in a very specific population (usually post menopausal women). It’s also important to understand that many of the studies that show benefits are funded by a company that sells collagen supplements which may skew results. Before starting a supplement you may benefit from evaluating gaps in your diet that could support collagen production such as adequate protein, vitamin C, zinc, and copper.
