Collagen is a protein that makes up most of our body’s structural tissue. After the age of 30, your collagen synthesis slows down and breaks down more than you regenerate[1] it. That’s when the fine lines and wrinkles start to appear.
In fact, collagen is the most abundant protein in the body, making up about 30-35% of your total body protein. So, it’s important to ensure you’re making enough collagen for a healthy body. But if you’re thinking of supplementing collagen, which is the best collagen powder for your needs? Read on to find out.
5 Best Collagen Powder On The Market In (June. 2023)

Who Should Use Collagen Powder?
Supplementing collagen peptides are important for anyone over the age of 30 who wants to maintain a young appearance and reduce the signs of aging. Stress also degrades collagen production,[2] so supplementing collagen is even more important if you lead a stressful lifestyle.
But it’s not only important for its anti-aging benefits. Actually, the benefits of collagen range from improving skin health and reducing wrinkle appearance to reducing joint pain and speeding up tendon injury recovery.[3]
What Type Of Collagen Powder Is Best?
The type of collagen you need depends on the health benefits you’re looking for. Collagen type I is the most prevalent in the human body, but there are 28 known types of collagen[4] in total. The most common types of collagen found in the human body are
- Collagen type I[5] – important in bone, skin, and connective tissue.
- Collagen type II[6] – a major component of cartilage and provides flexibility to joints.
- Collagen type III[7] – important in the skin, the aorta of the heart, and cartilage.
- Collagen type V[8] – contributes to the bone, cornea, muscle, liver, lungs, and placental tissues.
- Collagen type XI[9] – distributed around the body in cartilage, tendons, muscle, bone, etc.
The above types are fibrillar meaning fiber-forming, and all the other types are non-fibrillar,[10] meaning they don’t form their own fibers. Rather, they influence the shape of fibrillar collagen.
Most collagen powders tend to be made from bovine collagen, marine collagen peptides, or egg membrane. Collagen powders are usually hydrolyzed, meaning that the proteins have been broken down with enzymes to make smaller collagen peptides so they’re easier to digest and absorb.
But with so many collagen powders on the market, which should you buy? Read on for our top picks.
5 Best Collagen Powder For Your Healthy Life In 2023
Vitauthority Multi Collagen Burn Powder
Vitauthority is the best collagen powder for women because of its benefits for skin health, weight loss, and cellulite reduction.
- Clinically proven to reduce cellulite.
- Lab verified free from GMOs, pesticides, heavy metals, or contaminants.
- Contains a metabolism support complex.
- Only 7.8 grams of collagen per serving.
- Fish-derived ingredients might not be sustainably sourced.
- Chicken-derived ingredients might not be free-range.
Vitauthority is an unflavored collagen powder with added hyaluronic acid, vitamin C, and superoxide dismutase to aid collagen and elastin production and improve skin elasticity. This is the best collagen powder for cellulite because it contains SOD-B Dimpless, an ingredient clinically proven[11] to reduce to appearance of cellulite.
There are two main causes of cellulite development: (1) collagen fiber dysregulation and (2) fat cell enlargement. Studies show that SOD-B Dimpless can reduce fat cell size and regulate collagen fiber production, visibly reducing cellulite by almost ten percent after 28 days.
This collagen powder also includes a “metabolism support blend” of herbs such as Grains of Paradise and Sensoril Ashwagandha, some of which might help burn fat[12] and aid weight loss. However, the blends are proprietary formulas so you can’t determine if the amount in the blend is an effective amount to achieve desired effects.
Vitauthority Multi Collagen Burn Powder has 4.5/5 stars on Amazon.com reviews. It costs $59.99 for a one-off purchase or $50.99 per month when you subscribe (the first month is 25 percent off at $44.99). That’s $0.19 per gram of collagen. You can cancel your subscription anytime with 24 hours’ notice.
SkinnyFit Super Youth Multi-Collagen Peptides
SkinnyFit provides a high dose of collagen per serving and is the best collagen powder for weight loss as it contains apple cider vinegar.
- Includes apple cider vinegar for weight loss.
- Provides collagen types I-III, V, and X.
- 15.6 grams of collagen per serving.
- Contains added sweeteners, flavorings, and colors.
- Not third-party tested.
- Not allergen-free.
SkinnyFit’s collagen powder provides 15.6 grams of collagen per serving, more than double that of most on the market.
We also like that SkinnyFit includes vitamin C and hyaluronic acid. Vitamin C is important for skin health because it helps build collagen,[13] and it’s our skin’s secondary antioxidant after vitamin E. It can’t be regenerated, so you should ensure you’re getting enough vitamin C daily.
Moreover, a serving of SkinnyFit includes 200 milligrams of apple cider vinegar or ACV. Higher doses of ACV have been shown to balance the gut microbiome, improve mood,[14] and even help you lose weight[15] — most likely due to its blood sugar-balancing[16] effects.
Although this collagen powder says it’s unflavored, it does contain “natural flavorings” and is sweetened with stevia and monk fruit. A recent 2022 study showed that stevia affected the gut[17] microbiome, but further studies are needed to determine if this effect is beneficial or harmful to humans. It’s also not third-party tested for purity and isn’t confirmed allergen-free.
SkinnyFit Super Youth Multi-Collagen Peptides has 4.2/5 stars on Amazon.com. It costs $99.95 for a one-off purchase or $79.96 per month when you subscribe, which you can cancel anytime.
Peak Performance All 5 Multi Collagen Protein Powder
Peak Performance guarantees no contamination and includes an extra source of collagen compared to most other powders.
- Includes bovine bone broth protein.
- 1-for-1 donation to Vitamin Angels.
- Third-party tested.
- Doesn’t contain as many servings as stated.
- Doesn’t include hyaluronic acid.
Like other collagen powders, Peak Performance Provides collagen types I-III, V, and X. However, many collagen powders on the market are contaminated with toxins[18] such as antibiotics and heavy metals.
Peak Performance uses rigorous testing to ensure it’s the best collagen powder without heavy metals or other impurities, antibiotics, hormones, or toxins. They also don’t use artificial or refined sugars, flavors, or fillers. Customer reviews say that this collagen powder has no taste and mixes well into various drinks.
Most collagen powders combine four sources of collagen, but Peak Performance adds a fifth: bovine bone broth, in addition to the bovine collagen peptides common in supplements. While bovine collagen peptides come from cowhide, bovine bone broth comes from the bones. This adds a few extra amino acids, especially cysteine, histidine, and tryptophan, and makes Peak Performance a good choice for bone and joint health.
Peak Performance All 5 Multi Collagen Protein Powder has 4.4/5 stars on Amazon.com. It costs $35.59 for a one-off purchase or $32.03 per month when you subscribe, saving 10 percent. This comes to $1.18 per serving when buying one-off.
Ancient Nutrition Multi Collagen Protein
$12 on orders 25+ and free shipping: HEALTH12
Ancient Nutrition Multi Collagen Protein provides 10 types of collagen and is the best collagen powder for skin and hair health.
- Clinically-studied fermented eggshell membrane collagen.
- Provides 10 types of collagen plus probiotics.
- Published certificate of analysis.
- The container is only half full.
- Some customers complained about the slight taste.
Ancient Nutrition’s collagen powder provides collagen as well as vitamin C and probiotics, all of which have been shown to improve skin hydration.[19] They’ve included the highly bioavailable lipid metabolite form of vitamin C at 100 percent of the Daily Value to help your body make your own collagen.
Unusually, this supplement provides ten types of collagen. One source of collagen is a proprietary fermented eggshell membrane collagen, which they claim is clinically proven to improve joint, hair, and skin health,[20] making this the best collagen powder for hair.
The probiotic strain is called Bacillus coagulans, an SBO, or soil-based organism, which can improve gut health and protein absorption.[21] SBOs are also shown to survive the harsh conditions of the gut better than other strains.
Ancient Nutrition publishes its certificate of analysis online, proving its collagen powder to be free of common contaminants.
Ancient Nutrition Multi Collagen Protein has 4.5/5 stars on Amazon.com. It comes in two sizes, 45 servings for $49.95 or 60 servings for $59.95. That’s $0.11 and $0.09 per gram of collagen, respectively. When buying from ancientnutrition.com, you can save 15 percent per month if you subscribe.
Bulletproof Collagen Protein
Bulletproof Collagen Protein is unique in that it only contains one ingredient: hydrolyzed bovine collagen. Customers say the taste is neutral in coffee and it dissolves easily compared to other collagen powders.
- Simple formula with one ingredient.
- From grass-fed, pasture-raised cows.
- Dissolves easily and has a neutral taste.
- Only provides one source of collagen.
- Only provides collagen types I and III.
- No vitamin C or hyaluronic acid.
Bulletproof Collagen Protein only contains one ingredient: 20 grams of hydrolyzed collagen from bovine. This provides collagen types I and III, which are the most common types of collagen in the body.
In fact, 90% of the human body is type I collagen, which is the type of collagen in skin, bone, tendons, and organs. Collagen type III is often found alongside type I in the liver, bone marrow, and lymphatic system. However, Bulletproof doesn’t include type II collagen, which is the type found in cartilage, or collagen type V, which is found in hair.
The collagen comes from pasture-raised cows without added hormones. Bulletproof claims to use the parts of the cows bred for meat that would otherwise go to waste, making this collagen powder potentially the most eco-friendly.
There are 70 calories per serving and 65 milligrams of sodium. A serving size is two scoops, and each 17.6-ounce container has 25 servings.
Bulletproof Collagen Protein has 4.6/5 stars on Amazon.com. When buying from bulletproof.com, it costs $43.95 for a one-off purchase or $35.16 per month when you subscribe, saving 20 percent.
Benefits Of Collagen Powder
Reduces The Appearance Of Wrinkles
Collagen is crucial for healthy skin. As we age, the collagen in our skin degrades, resulting in wrinkles and thinning, sagging skin. Studies show that supplementing collagen can help reduce the appearance of wrinkles.
Systematic reviews have found that supplementing collagen reduces wrinkle appearance and improves skin hydration[22] and elasticity. In fact, supplementing collagen for just 12 weeks reduced wrinkles[23] by 35 percent. Plus, collagen can reduce the impact of stress on collagen production,[2] potentially reducing the appearance of aging due to stress.
Doses in the systematic reviews ranged from 2.5 to 10 grams of collagen per day for three to 24 weeks.
Might Improve Skin Hydration
If you suffer from dry skin, supplementing collagen might help, especially when combined with hydraulic acid,[24] vitamin C, and some types of probiotics.[19]
A clinical trial of a collagen supplement found it significantly improved skin hydration in women[25] compared to a placebo. However, the supplement used also provided acerola fruit extract, vitamin C, zinc, biotin, and vitamin E.
Might Reduce Joint Pain
The risk of arthritis increases with age, partly due to reduced synthesis of collagen type II[26] — the type of collagen in cartilage.
Studies suggest that oral collagen supplements can increase joint mobility and reduce joint pain[27] and is especially effective for reducing symptoms of osteoarthritis.[28] Other studies suggest collagen supplements can help treat chronic back pain,[29] too.
If you’re supplementing collagen for joint pain, ensure your powder includes collagen type II.
Might Improve Bone Strength
Bone is partly made of collagen type I,[30] and bone strength depends on the organization of collagen fibers. So could supplementing collagen affect bone strength?
One study found that postmenopausal women, who are at increased risk of bone fractures, lost less bone density when taking a collagen[31] supplement. Another study found that collagen peptides increased bone density[32] in the spine, too.
Other Benefits Of Collagen
Here are some other potential health benefits of collagen found in smaller studies. However, beware that commercial health claims for the effects of collagen[33] supplements on outcomes other than skin and bone health tend to surpass the available evidence.
- Might improve wound healing.[22]
- Might reduce inflammation and bleeding associated with periodontal diseases.[34]
- Might speed up tendon injury recovery.[3]
- Might increase nail growth rate[35] and reduce nail breakage frequency.
How We Choose The Best Collagen Powder
We chose the best collagen powders featured in this article based on several criteria, including
- The type and quality of the included ingredients.
- Whether the product was third-party tested.
- The grams of collagen peptides per dose*.
- The brand reputation.
*We considered 2.5 to 15 mg of collagen to be an effective and safe dose and multiple collagen types to be more effective than a single fiber type of hydrolyzed collagen.
Ways To Take Collagen Powder
Here are some of the most common ways to consume collagen powder:
- In smoothies
- Mixed with water
- Mixed into coffee
- Added to baking
- In pancakes
- In oatmeal
Consuming too much collagen powder isn’t dangerous, but it might cause some uncomfortable adverse side effects such as gas or bloating.[36] And, if your collagen product has probiotics in it, remember that these are live organisms and you do not want to cook them.
Final Thought
Our body is made of 90% collagen. However, our own production of collagen reduces as we age.
Studies show that supplementing collagen can improve skin health, but many collagen powders on the market are of poor quality and do not all provide all the important types of collagen. Each type is best for a specific purpose, so it’s crucial to buy the best collagen powder for your health goals — preferably ones that contain at least five types of collagen.
Whichever collagen powder you end up buying, make sure to pair it with a healthy diet, optimal hydration, and a balanced lifestyle that includes exercise to promote healthy aging and reduce wrinkles most effectively.
Frequently Asked Questions
That depends on your needs. For example, collagen type I is most effective for skin health, while type II is most effective for reducing joint pain. The best collagen fibers contain all five types of collagen peptides.
Collagen turnover is slow, so expect to take collagen for at least 12 weeks before seeing any changes in skin appearance. For joint and bone health, it could take up to one year.
Collagen supplements are unregulated, and some contain contaminants such as pesticides and heavy metals, which can have a negative impact on health. Be sure to buy collagen powder from a trusted brand and one that preferably has been third-party tested to be free from contaminants.
Yes, to see the most optimal changes in health, we recommend using collagen powder daily.
