How do Collagen and Vitamin C Work Together and What Are Their Benefits?

Collagen is essential for our skin health and several other aspects of health throughout our body. On its own, it's great for hydrating the skin, helping it to look plump and healthy, alleviating joint pain, bone pain, and connective tissue pain, it can improve gut health, and it can strengthen hair and nails.

One vitamin that is needed for the formation of collagen is vitamin C. It also happens to be important for our skin health. Vitamin C deficiency and collagen deficiency can both have a serious effect on our health.

Aging, sun exposure, genetics, and a poor diet are all reasons why our collagen production and vitamin C production can start to decline. These are also the typical reasons you would have a deficiency.

The good thing is, collagen and vitamin C work together in the body to provide great skin health benefits. Read on to learn more about how these two things are connected within the body, and what they can do for your health. 

Vitamin C and Skin Health

The benefits of vitamin C are great for both your skin health and your entire body. It can be found in the dermis and the epidermis of the skin. It maintains and forms blood vessels, skin, and bones.

It is water soluble, meaning the body cannot store it. This means we must eat foods that contain vitamin C daily.

For your skin health, you should try and increase the foods you eat that are rich in Vitamin C. There are many foods rich in Vitamin C. Vitamin C is also known as ascorbic acid. For vitamin C, citrus fruits are key, with grapefruit and lemon being some of the best for your skin. Even fruit such as raspberries contain a large amount of vitamin C. If you want to watch your sugar, try eating bell peppers. They are just as high in vitamin C but with a lower sugar content.

This vitamin is essential for both improving collagen production and naturally giving you stronger, glowier skin. It also helps to detox your body, especially your gut and liver, which is necessary to remove toxins and impurities that could affect your skin.

You can take vitamin C dietary supplements daily as well. This will ensure you're getting enough vitamin C. However, it is best to get most of your vitamins through food sources. Things like leafy vegetables, green vegetables, leafy greens, carrots and sweet potatoes (high in vitamin A and beta-carotene), citrus fruits, meats, and seafood are packed with vitamins.

Vitamins play a role in protecting against free radicals, heart disease, strengthening your immune system, improving collagen synthesis, preventing scurvy, vitamin B12 deficiency, biotin deficiency, and so many other issues. Your dietary sources should contain plenty of vitamins and nutrients.

Collagen and Skin Health 

Collagen is a protein (the most abundant protein in our body) made of amino acids. These amino acids act as building blocks in the body. The most important amino acids for collagen formation are proline and glycine.

Collagen can be found in our skin, connective tissues, bones, and tendons. Our natural collagen production decreases as we age by roughly 1% each year once we reach our 20's. The health benefits of collagen include strengthened skin, improved fine lines and wrinkles, stronger hair and nails, and increased production of collagen in the body. It also plays a role in joint and bone health. This is why it's important to maintain your collagen levels through collagen-rich foods and collagen supplements.

Thankfully, there are a lot of options for this dietary supplement. Some options include collagen peptides, hydrolyzed collagen, collagen powder, collagen protein, liquid collagen, collagen pills, and more.

With all of these options, it's likely you'll find one that works for you and gives you the results you are looking for. In a medical and healthcare setting, collagen can actually be used for wound healing.

Marine collagen is typically the go-to for beauty and skin issues. It has the greatest bioavailability of all collagen types, which means it absorbs 1.5 times faster than other types of collagen. It is derived from fish scales (skin) making it suitable for skin concerns. It's also important to make sure your collagen is hydrolyzed. This means that it is broken down into tiny particles that are easy to digest, whereas non-hydrolyzed tends to have molecules that are too big to break down in your stomach. When this happens, you don't absorb the collagen, and therefore don't get any benefits.

How does vitamin C affect collagen?

Vitamin C is needed for the synthesis and maintenance of collagen. It helps to produce collagen, as it has an active role in collagen synthesis. It also acts as a sort of glue that binds collagen fibers together.

Also, it helps in the process of regenerating vitamin E. Vitamin C is important for immune support, skin health, and the growth and repair of body tissues. The recommended daily allowance (RDA) for vitamin C is no more than 2,000mg per day, with a minimum of 75mg. 

Can you take collagen and vitamin C together?

Yes, you can take collagen and vitamin C together. In fact, doing so will likely boost your skin health even more than if you just took one of the supplements on its own.

There are a few things to keep in mind when choosing a vitamin C supplement and a collagen supplement. The benefits of collagen help to beautify you from the inside out. For collagen supplements, you want to make sure it's as clean as possible. This means no additives or flavorings. You also want to make sure the product is non-gmo or organic to ensure the highest quality. Otherwise, it may contain additives that could hinder the benefits of collagen. There are no known side effects of collagen supplements, making it a safe supplement to try. Vitamin C supplements are similar, as they are generally very safe. You should look for ones that don't have any excess ingredients. There are a lot of powder supplements that have added coloring and flavoring.

One thing to note in regards to skincare is that vitamin C does work on the skin topically, whereas collagen does not. Serums and creams that contain vitamin C are great for renewing skin cells, repairing damage, and making skin glow. Topical vitamin C can be strong, so it's important to wear sunscreen as well. Collagen, on the other hand, cannot be absorbed through the skin.
