The Active Ingredient Is: L-Serine

L-Serine is an amino acid used in protein synthesis and other metabolic processes. This product supplies pharmaceutical-grade L-serine as the active ingredient in capsule form.

Douglas Laboratories delivers the amino acid in a clean non-GMO formulation with minimal inactive ingredients, reflecting professional-grade manufacturing standards.

What Does L-Serine Do?

L-Serine is involved in brain health and nervous system support. It is described as contributing to the formation of myelin sheaths and phospholipids for cell membranes, supporting normal brain and nerve function.

These activities are listed in product materials as part of the nutrient’s role in supporting central nervous system processes, aligning with standard physiological functions cited for amino acids.
