Description
"Serine" is a non-essential amino acid naturally present in the body and obtained from dietary proteins. As a precursor to glycine and cysteine, it participates in neurotransmitter production, metabolic activity, and immune regulation. Myelin formation relies on serine, contributing to nerve protection and cognitive health. Enzymatic reactions and muscle repair also depend on its availability. Found in eggs, soy, and nuts, serine supports key biological functions, making it vital for brain health and energy metabolism.
Functions in the Body
Category
Deficiency Symptoms
Serine deficiency can lead to seizures, olfactory hallucinations, abnormal muscle movement, and lowered glycine levels.
Synergists & Antagonists
Serine works synergistically with glycine in protein synthesis and relies on vitamin B3, vitamin B6, and folic acid for its synthesis. No well-documented antagonistic interactions exist.

Warnings
Excessive serine intake may negatively impact immune function. Caution is advised during pregnancy, breastfeeding, and in individuals with kidney disease.
Food Sources
Serine can be found in nutritional yeast, almonds, walnuts, peanuts, chickpeas, lentils, meats, fish, and eggs.
Time Frame
Serine can be consumed at any time.
Depleted By
No specific depletion factors are noted, but the body’s need for serine may increase during intense physical activity or stress.
