What is serine and what does it do?

Serine is a non-essential amino acid made by the body and obtained from food. It supports protein synthesis and is involved in brain function and several metabolic pathways.

What is the difference between L-serine and D-serine?

L-serine is the common form used in proteins and general metabolism. D-serine is a stereoisomer that acts in the nervous system, including modulation of NMDA receptor signaling.

What are the potential benefits of serine supplements?

L-serine is studied for neurological support and overall metabolic roles. D-serine has been researched as an adjunct to standard care for certain psychiatric symptoms related to NMDA receptor function.

What is a typical serine dosage?

Common supplemental amounts are about 500–2000 mg per day, depending on the product and goal. Individual needs vary, so dosing is best personalized with a clinician.

Is serine safe and who should be cautious?

Serine is generally well tolerated at typical doses, but side effects can occur. People who are pregnant or breastfeeding, have kidney disease, or take psychiatric medications should consult a healthcare professional before using D-serine or higher-dose supplements.
