Frequently Asked Questions About L-Serine Supplements

What is L-Serine?

Serine is a non-essential, meaning the body synthesizes it, and it is comprised of amino acids that come in two types: L-serine and D-serine. L-serine can be created from other amino acids including glycine and other protein metabolites. It is converted to D-serine in cells, which support the nervous system. Since L-serine is not involved in the synthesis of mammalian proteins, it is not classified as a “Generally Regarded as Safe” compound by the FDA. It was discovered about 150 years ago, but research has been limited as to how far an understanding can be gained on the use and effects of the supplement.

How Do I Take L-Serine?

More often than not, this supplement is taken in a pill form. It can come as a powder that can be mixed in with water or juice, though. It can also be given by a doctor as an injection, too.

A typical dose is 300mg per day. We recommend speaking with your doctor before taking any supplements to determine the right dosage for you.

While a deficiency of L-serine has not been determined as detrimental, taking supplements to enhance the numbers of it present in the body does help several functions, as mentioned previously. It can be found naturally in the following foods:

  • Egg whites
  • Whole eggs
  • Swiss cheese
  • Provolone cheese
  • Lima beans
  • Bacon
  • Turkey
  • Wheat germ
  • Quinoa
  • Venison
  • Avocado

How Do I Pick a Good L-Serine Product?

You need to make sure that quality is the focus of the product. As with other supplements, some companies will use fillers and additives to stretch the ingredients being used in L-Serine. Therefore, it is essential to look for high-quality ingredients.
