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

New to this supplement

I only JUST received my order so can't comment on efficacy until I've used it for awhile. I WILL say that the order was filled promptly and service was great with tracking/ delivery information so would definitely use this company in the future!
