Collagen supplements have taken the health and wellness world by storm, with many touting their benefits for skin, hair, nail, and joint health. However, as with any supplement, it’s essential to examine the potential risks and side effects associated with taking collagen. In this article, we’ll delve into the world of collagen supplements, exploring the possible harm they can cause and what you need to know before adding them to your daily routine.
What is Collagen, and How Does it Work?
Before we dive into the potential risks, let’s first understand what collagen is and how it works. Collagen is the most abundant protein in the human body, making up approximately 25% to 35% of all proteins.

What are collagen supplements and how do they work?
Collagen supplements are dietary supplements that contain collagen, a protein found in the connective tissue of animals. They are often marketed as a way to improve skin, hair, and nail health, as well as to support joint health and reduce the signs of aging. Collagen supplements typically come in the form of capsules, tablets, or powders, and are usually made from animal-derived collagen, such as from cows, pigs, or fish.
When taken, collagen supplements are broken down into amino acids, which are then absorbed by the body. The amino acids are then used to build new collagen, which can help to improve the health and appearance of skin, hair, and nails. However, the effectiveness of collagen supplements is not universally accepted, and more research is needed to fully understand their benefits and potential risks.
What are the potential benefits of taking collagen supplements?
The potential benefits of taking collagen supplements include improved skin elasticity and hydration, reduced wrinkles and fine lines, stronger hair and nails, and improved joint health.
