# Glucosamine: Benefits, Uses, and Side Effects
What is Glucosamine?
Glucosamine is a naturally occurring compound found in the human body, primarily in the cartilage of joints. It plays a crucial role in maintaining joint health by supporting the formation and repair of cartilage. As a dietary supplement, glucosamine is commonly derived from shellfish shells or produced synthetically in laboratories.
Types of Glucosamine Supplements
There are several forms of glucosamine available as supplements:
- Glucosamine sulfate – The most commonly studied and used form
- Glucosamine hydrochloride – Contains higher concentration of glucosamine
- N-acetyl glucosamine – Used for different purposes than joint health
