Amino acids play an important role in constructing the vast array of structures in the body. Proteins‚ bones‚ muscles‚ and connective tissue all rely on proper amino acid levels for maintenance and growth. It’s incredible how much these tiny building blocks can do!

Serine is one of the many amino acids that help form the body’s vital proteins. Douglas Labs’ L-Serine Capsules contain 500 mg of L-Serine in each serving. This L-crystalline form of the amino acid is all-natural and bioavailable. This means you get the most out of your supplement with the convenience of easy absorption.

The amino acid serine also takes part in the formation of serotonin. This is a vital neurotransmitter that helps our neurons communicate every day. It may also help with the production of tryptophan‚ brain proteins‚ and nerve coverings. Who knew such a small building block can play this big of a role in brain health?

Douglas Labs is proud to offer you L-Serine Capsules with all organic and preservative free ingredients. Order through PureFormulas and help your body achieve potentially healthier levels of L-Serine today!

      High quality product not found in stores

      from VERO BEACH FL on 3/23/2020
      We live near the water where blue-green algae is a recurring problem. Our whole family takes these daily. We don't yet know whether it will help ward off neurological disease but so far see no harm in trying.


      Contains the only known supplement to address neurological diseases


      Price. We're not sure why but this product is much more expensive than other brands.

      Trusted Product

      from Evanston, Il. on 12/27/2012
      Im prescribed serine by my health care practitioner (one capsule in the evening). When it comes to brain health I believe that one should not cut corners and therefore purchase a high quality product from a trusted company - and I believe that Douglas Labs fits this criteria. I was taking phospatidylserine for a while but my practitioner - she is a doctor- said that theres not that much difference between the two - except for the costs. I couldnt find just L-Serine anywhere until I found Pure Formulas. Pure Formulas and Douglas Labs have allowed me to get L-Serine and save a considerable amount of money too.

      amazing supplement

      from Irvine, CA on 5/08/2012
      I started using L-Serine 500 mg by Douglas Laboratories about a month ago and feel so much better. My physician recommended and what a difference it has made. I have dificulty sleeping and this has helped. I have less anxiety and feel better overall. Great for fibromyalgia or chronic fatigue too!!
