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

L-Serine powder

I expected a pill and this is a powder. Nothing in the description says this is a powder. Very confusing.

The order was a bit difficult because I thought I could order from the web page but since I was on my cell phone, the prompts required my to download the apps with no apparent option to go back or decline the app. After getting past that hurdle, tracking the order was easy and efficient. The product arrived neatly packaged but with very little supporting information other than the contents, company logo and weight. The suggested serving is listed with the legal disclaimer. I had hoped for more information on what it can be used for but I suppose that is due to legal restrictions.

The best sleep aid.

This product is excellent great to take it 30 minutes before bed, it makes you sleep well and get up fresh never groggy. Other members of my family are using it with similar results.

I’ve been using this product for approximately two years - I love it. It’s so easy to use. A quick scoop in the morning coffee is my favorite method of delivery. Product arrived quickly. I loved the tracking.
