L-Serine is widely used in the pharmaceutical industry as a key ingredient in parenteral nutrition solutions, especially for patients who cannot obtain adequate nutrients through oral intake. It supports protein synthesis and metabolic functions in the body.

In cell culture and biotechnology, L-Serine is an essential component of culture media, promoting cell growth and viability, particularly in the production of monoclonal antibodies and recombinant proteins.

It is also used in skincare products due to its moisturizing properties. As a natural component of the skin’s moisturizing factor, it helps maintain hydration and improve skin barrier function.

Additionally, L-Serine is being studied for its potential therapeutic role in neurological disorders, such as amyotrophic lateral sclerosis (ALS) and certain inherited serine deficiency disorders, where supplementation may help slow disease progression.
