Best Collagen Supplements

Verywell / Sabrina Jiang

Collagen is the main structural protein of connective tissues such as bone, skin, cartilage, and tendons. Collagen peptides are the broken down elements of the longer protein chain and are more bioavailable and absorbable by humans in this form. It has been hypothesized that if humans ingest collagen from outside sources it will support and optimize our health and address physiological needs posed by aging and exercise.

The primary function of collagen is to help tissues withstand stretching. Although collagen loss starts between the ages of 18 and 29, after age 40, the body can lose around 1% per year; at around age 80, collagen production can decrease 75% overall in comparison to that of young adults. This is where supplements come in. By taking a supplement, it is thought you may be able to replenish some of the collagen your body has lost, and hopefully, see the real effects of adding this supplement to your diet. 

Collagen supplements are made by extracting the collagen from connective tissues of animals such as cows, fish, and chickens. These supplements can be taken in powder and capsule form as well as added to foods such as protein bars. Since collagen makes up 80% of our skin, collagen supplements have been regarded as a tool to improve and maintain skin health as well as joint, gastrointestinal, and bone health.

Below are the best collagen supplements.

If you're looking for a collagen powder that accommodates all food sensitivities, Great Lakes' Collagen Hydrolysate (view at Amazon) is a no-brainer. It's gluten-free, non-GMO, and kosher, and is flavorless so you can add it to any smoothie or drink without taking away from the taste.

What to Look for in a Collagen Supplement


There are many types of collagen; however, there are three that are generally used. Type 1 and type 3 are generally used for skin health and elasticity, whereas type 2 is used for cartilage and joint health. Choose a type that aligns with your needs.


Collagen comes in many different forms and types, and there’s no one-size-fits-all way to ingest your collagen. It comes from various sources such as bovine (cow or beef), chicken, fish, or eggshells. Unfortunately, there is no vegan source of collagen that’s available.

To ensure you’re getting a high-quality product, look for collagen that’s grass-fed, pasture-raised bovine, or made from wild-caught marine sources.


Some collagen supplements are flavorless, whereas others come in a variety of flavors. When choosing a flavor, consider how you will use the supplement. For example, are you baking with it, mixing it into a smoothie, or simply drinking it mixed with warm water?


The key differences between a collagen powder and a collagen supplement are the delivery method and dose. Collagen supplements that come in a pill form are simply capsules filled with powdered collagen.

However, the serving size in capsule form is often less than that of its powdered counterpart; it generally takes multiple servings of the capsule form to equal the dose of one serving of powdered collagen. This may be problematic or undesirable for some. If you are someone who has trouble swallowing capsules or who desires a larger dose of collagen at once, then opt for the powdered form. It is also easy to incorporate the powdered form into your morning routine such as to your coffee or morning smoothie.

However, if you are someone who prefers the convenience of simply taking a capsule with a glass of water and calling it a day, and do not feel a need larger doses of collagen, then the pill form may better suit your needs

Potential Allergies

Those with a fish, shellfish, or egg allergy should avoid collagen supplements as many of them are made from these ingredients. Make sure to check the full ingredients list, including any notes that indicate that the product was processed in a facility that processes other ingredients you may be allergic to.

There are some reports that collagen supplements may cause mild digestive symptoms or a bad taste in the mouth. It’s important to go over the labels of supplements you’re using with your physician because the FDA does not regulate dietary supplements, including collagen

Frequently Asked Questions

  • What does "hydrolyzed" mean?

    If a product is “hydrolyzed," that means that it has been broken down to a size that makes it easy for your body to absorb. Collagen products that are used mainly for beauty purposes may contain hydrolyzed collagen

  • Why does my collagen powder include vitamin C and hyaluronic acid?

    Some collagen supplements include complementary ingredients such as vitamin C, which stimulates collagen synthesis, and hyaluronic acid, which promotes optimal skin moisture.

  • Which is better, marine-based or bovine-based collagen?

    Choosing marine-based collagen or bovine-based collagen really boils down to your preference. If you follow a pescatarian diet, then marine collagen would be a better fit.

  • Is grass-fed or wild-caught collagen worth the price?

    Collagen products made from non-grass-fed cows or farmed fish may be cheaper, but it also comes with the knowledge that you won’t know the history or entirety of what you’re putting into your body. Most collagen products range from $20 to $70 for 10 ounces and can go up depending on the number of ounces in the product. If clean eating is important to you, you may want to opt for a higher-priced collagen supplement that clearly states where it gets the collagen in its products.

What Experts Say

"Collagen supplements are a great way to boost protein intake while promoting skin, hair, and nail health. Typical protein powders made from whey, casein, or pea may be hard on sensitive stomachs. I find that collagen powder is better tolerated and can easily be implemented into the daily diet. I recommend mixing it into your coffee or tea, blending it into a smoothie or soup, or adding it to your overnight oats." Eliza Savage, MS, RD, CDN
