What Is L-Serine?

L-Serine is a nonessential amino acid used in the biosynthesis of proteins that plays a part in a wide range of body functions.

L-Serine Benefits

L-Serine combines with fatty acids to create phosphatidylserine which may support brain function. It also converts into D-Serine, which may support the nervous system, and L-Serine is used by the body to create L-Tryptophan, a chemical that may support healthy sleep and mood.

  • Support brain function
  • Protect the nervous system
  • Promote healthy sleep
  • Aid healthy mood
  • Help boost muscle endurance

I recommend this product

Excellent product. Powder dissolves easily in water and tastes good. My husband takes it for neuropathy and he feels it gives him a boost.

I recommend this product

I have had good results using this product to calm tremors and get rid of “brain fog”. The sending of the product as ordered leaves a lot to be desired with this company.
