We dug into the research to provide you with answers, including the (science-backed) health benefits of taking a collagen supplement and what to look for in a supplement. With this data, we analyzed 20 of the top collagen products, read through their ingredients, certifications, and reviews (including our own) to compile a list of the Best Collagen Supplements to buy.

Let's start with, What is Collagen?

Collagen is the vital building block of our bodies, found in skin, hair, nails, bones, joints, muscles, and tendons. Unfortunately, as we age, our collagen production dramatically slows down.

According to New York Dermatologist Whitney Bowe, author of The Beauty of Dirty Skin: The Surprising Science of Looking and Feeling Radiant from the Inside Out, our body's collagen is like ropes of protein, "when we're young, the ropes remain tight, but as we age, the ends begin to fray."

We begin to lose about 1% of collagen per year in our mid-20s and lose as much as 30% during the first 5 years of menopause.

What are the Benefits of Taking a Collagen Supplement?

  • Improved skin elasticity and wrinkle depth

  • Improved skin hydration

  • Improved joint health

  • Increased bone strength

The Science Behind Collagen

According to a study conducted by the Collagen Research Institute in Germany, the results of their twenty-year research indicate "the inclusion of collagen peptides in the diet can lead to various improvements in health."

It showed an improvement in; skin elasticity, the recovery of lost cartilage tissue, reduced activity-related joint pain, strengthened tendons and ligaments, increased lean body mass, and increased bone density in postmenopausal women.

Joint Health and Bone Strength

Our bones are made up of collagen, and as we age and collagen production slows, it makes our bones weaker. Menopause leads to an increased risk for osteoporosis in women.

The National Library of Medicine has published several studies supporting collagen supplements improving joint health and bone strength.

One study found that taking collagen with a calcium supplement (rather than calcium alone) improves bone mineral density.

Another study concluded collagen to be an "attractive agent for long-term use" in the treatment of osteoporosis and osteoarthritis.

And another study found that athletes treated with collagen supplements saw improvement in joint pain.

Skin Health

As we age and collagen production significantly decreases, it leads to several common aesthetic skin concerns- including fine lines, wrinkles, loss of firmness, and uneven skin texture.

A study conducted by the Department of Food Science and Biotechnology at the College of Life Science in Korea found collagen-peptide supplementation to be an effective remedy to improve hydration, elasticity, and wrinkles in human skin.

Another study published in the Journal of Medical Nutrition and Nutraceuticals states, "oral supplements consisting of hydrolyzed collagen, hyaluronic acid, essential vitamins, and minerals leads to a significant improvement in wrinkle depth and a noticeable improvement in elasticity and hydration of the skin."

Finally, the National Library of Medicine published a study that found "ingestion of hydrolyzed collagen for 90 days is effective in reducing skin aging, as it reduces wrinkles and improves skin elasticity and hydration."

What is Hydrolyzed Collagen?

Hydrolyzation means that the collagen has been broken down into smaller components called Peptides, which are better absorbed in the gut and then delivered to skin and joints through the bloodstream.

How to Use Collagen?

Collagen powders easily dissolve in liquid and food, so you can add it to whatever you're drinking (coffee, juice, smoothies) or eating (yogurt, oatmeal, or add to baked goods)- get creative and start incorporating it into your life.

It is Not a Quick-fix

Just like anything that requires changes, collagen is not a 'quick fix.' Instead, consistency is the key- it can take up to three months for your body to start benefiting from a daily collagen supplement.

And like vitamins, skincare, or dietary changes- it's a lifestyle choice you have to stick with. If you don't use it regularly, you will not reap the benefits.

Finally, always ask your doctor before adding a new supplement.

But, with all the products on the market, the big question is... How do you know what to buy?

When choosing a collagen supplement, not all are created equal, so be careful and know what you are buying.

  • First, look for hydrolyzed collagen. As mentioned above, that is the key to better absorption and is easily soluble in food and beverages.

  • And look for a product with a diverse amino acid profile that contains collagen Types I and III.

Type I is the most important, comprising over 90% of the collagen in the human body. And Type III supports the structure of muscles, organs, and arteries.

  • Finally, be sure you are looking at the amount of collagen per serving.

All of the products listed below contain high-quality Type I and III grass-fed Bovine Collagen- except for the Marine Collagen, which has only Type I.
