Is Hyaluronic Acid Gluten Free?

Hyaluronic acid is a glycosaminoglycan, a type of molecule that is naturally present in the human body, particularly in connective tissues and skin. It is renowned for its ability to retain moisture and is widely used in the cosmetic and skincare industry for its hydrating properties. While it is sometimes included in dietary supplements, it is not commonly used as a food ingredient. Hyaluronic acid can be derived from both animal and microbial sources, although vegan versions are typically produced via bacterial fermentation.
