Serine
What is Serine?
Serine is a non-essential amino acid commonly found in dietary proteins. It can be made by the body or obtained through the consumption of foods like soy products, nuts, and eggs.
In supplements and cosmetics, serine is used for its potential role in cell proliferation, enzyme function, and hydration. The evidence on its health benefits varies, with some supporting its role in skin health and cognitive function, although this is still an active area of research.
When you see serine on a label, it's typically included for its potential supportive effects on health and skin care rather than as a nutrient you must gain from the diet.
Commonly found in: supplements, makeup, personal-care products, functional beverages
