Best L-Serine Supplements

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.

L-Citrulline is an amino acid which supports plasma levels of L-Arginine and L-Ornithine when taken as a supplement. It also supports the ammonia recycling process and the metabolism of nitric oxide. Overall, this helps support areas where nitric oxide is relevant including athletic performance and cardiovascular health.

As a supplement for circulatory health support, take two 600 mg capsules in the morning with food. Repeat this dosage again with lunch and dinner. To support endurance when exercising, take 6-8 capsules about an hour before exercising.

Vitamins, minerals and amino acids form the brick-and-mortar foundation of a healthy body. The 2015 Dietary Guidelines Advisory Committee reported that many Americans fall short in obtaining sufficient quantities of these important nutrients, including vitamins A, C, D and E, folate, calcium, magnesium, potassium, and fiber. Also, the prevalence of insufficient nutrient intake tends to increase with age. 35 to 40 percent of older adults who do not take supplements have inadequate B6 intake, and older adults often have difficulty obtaining enough B12 from their diet. Supplementation with vitamins, minerals and amino acids can play a valuable role in helping to fill these gaps.*

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

How Do I Pick a Good L-Serine Product?
