• SUPPORTS NEURON HEALTH - L-Serine is a key component in the synthesis of various phospholipids needed to support neuron health.
  • SUPPORTS AMINO ACID PRODUCTION - L-Serine is used by the body to support the production important amino acids such as Tryptophan, L-Cystine, and Glycine.
  • SUPPORTS HEALTHY SLEEP - L-Serine supports the production of amino acids like Tryptophan and Glycine that may support healthy sleep.
  • MANUFACTURED IN THE USA - Our L-Serine is manufactured right here in the USA and is tested for purity and potency.


L-Serine is an amino acid which supports neuron proliferation and health. It also supports the production of purines, pyrimdines, and important amino acids such as Tryptophan, L-Cystine, and Glycine. L-Serine also supports the proliferation and maintenance of new cells.

While the body does produce some L-Serine, it does not do so in high enough quantities to meet all the body’s demand for it so an external supply from diet or supplementation is recommended.

Recommended Dosage

For general use as a supplement, our recommended L-Serine dosage is 2000 mg per day. (4x 500 mg capsules.) L-Serine is water soluble and so does not need to be taken with food. It is often used in the evening, as it has a beneficial effect on sleep quality.

While we typically don’t recommend a dosage of over 6,000 mg per day there have been studies showing its safe use at dosages as high as 15,000 mg per day. We recommend avoiding doses this high as there is a much higher potential for side effects.

L-Serine Side Effects

L-Serine is well tolerated with few side effects, but some have been reported especially at high doses. The most common side effects associated with L-Serine are diarrhea and GI discomfort. Please consult your physician before taking L-Serine.
