Collagen refers to a group of related proteins in the human body. The proteins make up
- skin
- joints
- cartilage
- tendons
Collagen supplements usually come in the form of oral pills, tablets, or capsules. Liquid varieties are also available.
When a person takes them orally, collagen supplements may help promote health and healing in the below areas of the body.
Skin health

The study included fewer than 80 participants who were all females and used only Elasten supplements. As a result, the findings may not be applicable across all collagen supplements or people.
This collagen supplement also included other ingredients, such as acerola fruit extract, vitamin C, zinc, vitamin E, and biotin. The placebo did not contain these nutrients.

With this in mind, a person should look for products with third-party testing. Companies, such as U.S. Pharmacopeia and NSF International, provide purity and quality control testing for different supplement brands.
People can also explore online reviews of both the company and the products they offer. However, these reviews are anecdotal, meaning they may not apply to everyone.
Before ordering any supplement, an individual should consult with their doctor to ensure the supplement will not interfere with their current medications or any underlying health conditions.
Vegan collagen
Most collagen comes from bovine hide, so it is unsuitable for people following a vegetarian or vegan lifestyle. While some vegetarian collagen supplements are available, those following a vegan lifestyle may want to check that the supplements do not use animal products.
Most of the supplements people think are vegan collagen are actually labeled as collagen boosters or collagen builders. They do not contain any collagen. Instead, they have nutrients that may support collagen synthesis, so they may not produce the same effects as supplements in the studies.
Further to that, scientists have discovered a way to produce vegan collagen using bacteria and the yeast strain Pichia pastoris, though there are currently no commercially available products on the market.
