It seems nowadays the word collagen is synonymous with healthier hair, skin, and nails but can collagen actually help your hair grow? Here’s what you need to know.

All About Collagen

To better understand how collagen affects hair growth, let’s first do a quick crash course on collagen in general. Collagen is the most abundant protein in our bodies, but as we get older our bodies naturally make less and less of it. Collagen is one of the major building blocks of bones, skin, muscles, tendons, and ligaments, so as you can imagine as the body starts to make less, you can see and feel the effects in your skin, bones, and joints.

When collagen is taken as an ingestible, it is quickly absorbed into the bloodstream, helping replenish your body with collagen more effectively than topical beauty products. Our collagen peptides are also “hydrolyzed”, which means that they have been broken down through a particular type of water synthesis to allow them to be absorbed much quicker than non-hydrolyzed collagen or gelatin (you can read more about the absorption of Collagen For Her here). Hydrolyzed collagen then provides amino acids that are needed by the body to build connective tissue and help regenerate cell growth.

What about biotin?

Biotin is widely known as a supplement that helps with hair growth. Biotin, also known as Vitamin H, is one of eight B vitamins. Biotin plays a number of important roles in the body such as helping the body convert food into energy and maintaining healthy hair, skin, and nails. Biotin is found in food sources such as egg yolks, legumes, nuts, seeds, and nutritional yeast but can also be obtained from supplements such as Collagen For Her’s Marine Collagen Beauty Blend, which contains 100% daily value of biotin in addition to collagen.

How Collagen Can Help with Hair Loss and Thinning

To summarize, collagen is made up of 18 amino acids. Our hair is primarily made up of the protein keratin and in order for our bodies to produce keratin, it uses amino acids such as proline. By taking a collagen supplement that is rich in amino acids, it can promote hair growth in addition to other benefits for overall health.

How to Pick the Right Collagen Supplement for Hair Growth

The most important factor when deciding which supplements to take is knowing how bioavailable they are, meaning how well they are able to be absorbed by the body. The definition of bioavailability is the degree and rate at which a substance (i.e. a supplement) is absorbed into a living system (i.e. our bodies). Anything we put into our bodies (vitamins, minerals, supplements, pharmaceutical drugs, etc.) will only take effect if it can be absorbed by the body. This is why it is important to know how bioavailable collagen supplements are before choosing one.

Our Collagen Pick

Our favorite collagen supplement for women is Collagen For Her. All of their collagen products pass the bioavailability test and on top of that are non-GMO, gluten free, dairy free, sugar free, and soy free (plus, it’s a woman-owned company).

A great place to start is either their Unflavored Collagen Peptides or Multi-Collagen Capsules. The unflavored collagen peptides are flavorless and tasteless, so you can add a scoop to coffee, tea, smoothies, baked goods, etc. One scoop has 11g of collagen and 10g of protein. If you prefer collagen in capsule form, their multi-collagen capsules are a great option too.

If you are looking for even more benefits for hair, skin, and nails, check out their Marine Collagen Beauty Blend. This product is sourced from marine collagen, so it is pescatarian friendly, and contains 100% daily Vitamin C, biotin, and hyaluronic acid in addition to collagen for added hair and skin benefits. This product is also flavorless, so you can add it to just about anything. One scoop contains 5g of collagen and 5g of protein.
