The Active Ingredient Is: L-Serine

L-Serine is an amino acid involved in normal brain biochemistry and supports neuronal health. This form occurs naturally in dietary proteins and is commonly used in supplements to support brain function, including phospholipid synthesis and neurotransmitter production.

What Does L-Serine Do?

L-Serine participates in phospholipid synthesis for brain cell membranes and assists with the production of tryptophan and serotonin, supporting normal mood and sleep-related processes. Dr. Yamamura of Sleep Medicine at Osaka University found improvements in subjective sleep quality with L-Serine supplementation.
