Collagen is the main structural protein that forms our body's connective tissue—such as bone, skin, cartilage, and tendons. It is widely believed that if humans ingest collagen from outside sources, it will support and optimize our health and address physiological needs posed by aging and exercise. Some studies have found that taking oral collagen supplements may "increase skin elasticity, hydration, and dermal collagen density," all things that decrease as we age.

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 and powders come in. By mixing a powder into your favorite smoothie or morning coffee, you can replenish some of the collagen your body has lost, and hopefully, see the real effects of adding this supplement to your diet. 

Research on collagen supplements is fairly new, and not enough studies have been done to support the many claims that can be found on bottles. Always speak to your healthcare team before adding a supplement—including collagen— to your routine.

What to Look for in a Collagen Powder

Type: 

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.

Source: 

Collagen comes from various sources such as bovine (cow or beef), pork, fish, or eggshells. Although more studies need to take place, initial reports found that eggshells do not contain a significant amount of collagen, so if you’re looking to add this supplement to your diet, it’s best to stick with bovine or marine collagen.

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.

Potential Allergens: 

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.

Potential Side Effects: 

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

Flavor: 

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.

Here, the best collagen powders:

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 like 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

“Make sure your collagen supplement contains vitamin C. The presence of this important vitamin is necessary for collagen synthesis. And be sure to add antioxidants to your collagen regimen. Collagen fibers are a food source for free radicals, so antioxidant protection is super important, as free radical damage is the number one cause of aging.” —Olivia Pelaez, MS, functional nutritionist, and education coordinator at Vital Proteins
