Why your body needs collagen 

As the most abundant protein in the body, collagen plays a key role in maintaining healthy-looking hair and skin, joint and bone health, and can help build muscle mass and support an active lifestyle.[2,3]  Here’s the unfortunate biological reality though: the older you get, the less collagen your body produces. It starts to decline between ages 18-29. By 40, we may lose about 1% per year. This may lead to weaker and more brittle hair and nails, less mobility, a loss of skin elasticity, and more visible fine lines and wrinkles.[2,3]

by Vital Proteins


  • Made in the USA
  • Gluten and dairy-free
  • Certified grass-fed bovine collagen


  • 110 mg sodium
  • No 90-day money-back guarantee


Collagen Peptides by Vital Proteins is formulated with 20g of grass-fed and pasture-raised collagen. 

Like Primal Collagen by Primal Harvest, the Vital Proteins formula is easy to use. Although this unflavored formula is a solid choice for a collagen powder, some people may want to note that it contains 110 mg of sodium. This is especially something to consider for those watching their sodium intake. It also makes the product less versatile as the sodium content may impact the flavor.

4. Multi Collagen Protein

by Ancient Nutrition


  • Hydrolyzed bovine collagen 
  • Neutral flavor
  • With probiotics & vitamin C


  • Price
  • No 90-day money-back guarantee


Ancient Nutrition's Multi Collagen Protein is a pretty solid choice for a collagen supplement. It contains 10g of hydrolyzed collagen per scoop. Their collagen is sourced from grass-fed and pasture-raised bovine collagen and also contains probiotics and vitamin C.

It has a relatively neutral flavor making it easy to drink when added to other beverages. Although it dissolves fairly easily into cold drinks, it does seem to take longer to dissolve than some other collagen powders. Some consumers also reported that it did not dissolve as easily into warm drinks. 

This is generally a great choice, but you may want to note that it's a little pricier than some of the other products featured on this list. 

5. Super Youth Collagen

by SkinnyFit


  • Hydrolyzed bovine collagen
  • 14 g protein
  • With vitamin C


  • 2-scoop serving size
  • Price
  • Contains fish and egg


Super Youth Collagen by SkinnyFit includes 15.6 g of hydrolyzed collagen per serving, sourced from bovine, fish, chicken, and eggshell membrane. It also includes vitamin C, apple cider vinegar, and hyaluronic acid and is sweetened with stevia leaf and monk fruit extracts. Each container consists of 28 servings of unflavored collagen powder.  

Although the formula includes a range of collagen sources, the addition of fish collagen and eggshell membrane means this product may not be suitable for all consumers. Some may find the two-scoop serving size inconvenient in comparison to other products that have a one-scoop serving. The addition of stevia and monk fruit gives the product a little sweetness which means some may find that it is not totally neutral. Finally, you may want to consider the price of the product. At $99.95 for a one-time purchase (about 28 servings), this powder is less wallet-friendly than some other options.

What is collagen?

Simply put, collagen is a protein that forms the connective tissue all over our bodies. It is found in skin, nails, bones, joints, ligaments, and tendons. Collagen is primarily made up of amino acids and makes up about 70-80% of the dry weight of your skin.[2]

What Can Collagen Supplements Do?

Taking a collagen supplement is a convenient way to increase your collagen, protein, and amino acid intake. Although collagen is also present in foods such as bone broth, one huge benefit of a supplement is that the exact quantity of collagen is listed on the label. With a high-quality collagen supplement, you can always be sure you know exactly how much you’re taking. 

Type I

This is the most abundant collagen in the human body, found in skin, bone, ligaments, and even teeth. Type I collagen is the primary building block of your skin, and may support skin elasticity and hydration. Bovine collagen is a common source of type I collagen. [3,4]

What To Look For In A Collagen Supplement

What Are The Different Collagen Sources?

Bovine Collagen

Naturally sourced from cattle, bovine collagen is rich in collagen types I and III. It also contains protein and a diverse amino acid profile. Because it delivers types I and III, it’s often used for skin, hair, nail, and joint health. [5]

Marine Collagen

Rich in collagen type I, this collagen is sourced from different marine species, typically fish (skin, bones, fins) but also jellyfish, sponges, and other by-catch from the fishing industry. [5]

Chicken Collagen

Chickens also provide a natural source of collagen, including types I, II, III, and V. These are usually extracted from different parts of chickens such as the feet, neck, skin, and muscles. [5]

All Collagen Is NOT Created Equal

With over 300 various collagen supplements on the market, choosing the collagen that is right for you can seem like an uphill battle. When choosing a collagen supplement, always read labels, verify origins of ingredients, or research these important details before making your decision:

What To Try To Avoid In A Collagen Supplement

Type II

Sometimes colloquially referred to as “joint support” collagen, type II is found in the cartilage that supports our joints. That’s why some people turn to type II collagen when they experience joint concerns.  Hydrolyzed chicken collagen is considered a good source of type II collagen.[5]

Type III

Usually associated with type I collagen, these two types make up the two most commonly-found types in our body. Also highly beneficial for supporting skin health, type III collagen makes up a large part of our skin and organs. Bovine collagen is also a source of type III collagen.[3]

Type V

This type of collagen helps to support muscles and bones and is often sourced from eggshell membrane. [6]

Type X

Like type V collagen, type X is also typically sourced from eggshell membrane - a rich source of not only collagen but essential amino acids. This type of collagen can help support bones. [6]

TIP: Did you know that a high-quality collagen powder can make a great addition to your morning coffee or tea? 

Premium collagen powders have no flavor and dissolve easily into any drink - hot or cold. This makes it easy to add to your daily wellness routine which means you're likely to see positive changes!
