What is L-Serine?
This nonessential amino acid is synthesized by the body using glycine. It’s also found naturally in eggs, meats, and soy protein.
Phosphatidylserine, a similar supplement, is formed using L-serine and fatty acids.
L-Serine vs D-Serine
D-serine is the synthetic form of serine and has a slightly sweet taste. L-serine is better absorbed by the body and has a slightly sweet, but slightly sour taste.
In one study, taking L-serine before bedtime reduced the time needed to fall asleep.
Powder Dosage and Instructions
Take 2 grams of L-Serine once daily.
