What is Collagen & Why Would You Need Collagen Dietary Supplements?

Collagen is a structural protein found in our bodies that has glue-like properties to bind things together. It is located in the skin, hair, nails, bones, and joints as it aids in maintaining the health of all these parts.

As stated in the article entitled “The Collagen Family” published in Cold Spring Harbor Perspectives in Biology, collagen is the most abundant protein in mammals, comprising about 30% of total protein.

Here are a few important needs of collagen in the human body – it acts as a support structure and mechanical strength in the form of tissues to keep their shapes strong.

Collagen production is gradually reduced as a person grows old. Such aging factors contribute to several health issues like wrinkles in the skin, weakening tendons, and stiffened blood vessels. That’s where collagen dietary supplements can help.

According to board-certified dermatologist Dr. Shereene Idriss:

“Collagen also supports cell turnover that helps buff away dead skin cells naturally. Basically, it’s the holy grail of healthy skin which is why it’s crucial to take care of collagen in your skin—no matter what age you are.”

How Collagen Supplements Help Skin

According to the study revealed in Dermatology Practical & Conceptual, collagen supplements, both oral and topical, are highly effective in improving the skin texture & enhancing skin health.

Collagen helps by enhancing skin moisture, elasticity, and hydration and lessening skin lines, crow’s feet, and skin roughness. Of all the supplemental options, the best absorbed are oral and, in particular, supply the skin with those components that are required for building new collagen structure.

What Collagen Supplements Are Best For Skin?

  • Type of Collagen: For skin, Type I, III, V, and/or X are preferable.
  • Source: When sourced from good sources such as bovines, marine, or chicken-derived collagen, the absorption rates are usually better.
  • Hydrolyzed Collagen (Collagen Peptides): Collagen supplements with hydrolyzed peptides for skin are found to be more effective in improving skin elasticity than other forms of Collagen and are assimilated much easier by the body.
  • Supplemental Nutrients: Ingredients consisting of vitamin C, hyaluronic acid or zinc help increase the rate of collagen production in the skin.

Things to Avoid When Buying Collagen Supplements

  • Lack of Ingredient Transparency: Avoid purchasing supplements that keep the full ingredient list or source hidden from the users.
  • No Money-Back Guarantee: Lack of guarantee may indicate a lack of confidence in the quality.
  • Artificial Additives and Fillers: Avoid collagen supplements with synthetic colors, flavors, or unnecessary fillers.
  • Absence of Third-Party Testing: Do not take supplements that have not undergone testing for both purity and concentration by independent parties.

What Do Experts Say About Collagen Supplements?

Board certified dermatologist Dr. Joshua Zeichner discussed the benefits of collagen supplements for skin:

Recently, there has been new data suggesting that oral collagen supplements may be effective. The idea is that the active collagen fragments are absorbed through ingestion and circulate through your bloodstream to your skin.

More data needs to be gathered to validate initial studies, but if effective, these supplements can help the way we treat aging skin.

  • Collagen Supplements for skin can tighten the complexion.
  • These products can smooth wrinkles and fine lines.
  • Collagen Supplements can improve skin elasticity.
  • These products can improve skin hydration and eliminate dryness.
