NOW L-Serine 500 mg (120 Capsules)

L-Serine is a non-essential amino acid that plays a fundamental role in numerous physiological processes. It is naturally synthesised by the body and is also found in a variety of protein-rich foods. As a building block of proteins, L-Serine is involved in the formation of phospholipids — key structural components of every cell membrane — making it integral to cellular integrity and function throughout the body.

Beyond its structural role, L-Serine is a precursor to several important compounds, including glycine and cysteine, as well as phosphatidylserine and sphingomyelin, which are essential for healthy nervous system support. It also plays a part in the synthesis of purines and pyrimidines, the foundational components of DNA and RNA, underscoring its importance in cellular metabolism and overall biochemical balance.

Produced in a GMP-certified facility, this product reflects NOW’s long-standing commitment to quality, purity and value — making it a practical daily addition to a balanced nutritional routine.
