Description

If you’ve been hearing about L-serine, you’re in good company! This trending non-essential amino acid is making headlines for its potential to support cognition as a part of healthy aging. We’ve got the scoop on our blog: Could L-Serine be a Brain-Health Game Changer?

L-serine is important to a variety of structures and functions within your body. Cell proliferation, nervous system functions and healthy brain function all require adequate intake of L-serine. As a neurotrophic factor, metabolism of L-serine produces D-serine and phosphatidylserine which your body needs for neuronal development and neurotransmitter health.

While the body can naturally synthesize some of the L-serine needed for wellness, supplementation provides a targeted means of boosting this process and its benefits. The benefits even extend beyond brain health, with new research indicating that L-serine metabolism can also contribute to improved overall immune function as well as helping maintain healthy glucose levels.

High-purity Swanson AjiPure® L-Serine is produced through a fermentation process by the amino experts at Japan’s Ajinomoto, Amino Science LLC, the world leader in pharmaceutical-grade amino acids.

FAQ
  1. Why take an L-serine supplement?
    L-serine is a naturally occurring amino acid that supports healthy cell membranes, protein synthesis, and normal nervous system function. Although the body produces L-serine and it is found in protein-rich foods, supplementation provides a consistent way to support brain health and overall cellular wellness.
  2. What does L-serine do in the body?
    L-serine helps build proteins and phospholipids, key components of healthy cell membranes. It also supports normal cellular communication and serves as a building block for compounds involved in brain and nervous system function.
  3. How does L-serine support brain health?
    L-serine helps maintain the structure of healthy nerve cell membranes and supports normal communication between nerve cells. It also contributes to the production of phospholipids that are essential for healthy brain function and cognitive wellness as part of healthy aging.
  4. What makes Swanson AjiPure® L-Serine unique?
    Swanson AjiPure® L-Serine delivers 500 mg of AjiPure® pharmaceutical-grade L-serine per serving. Produced by Ajinomoto through a plant-based fermentation process, AjiPure® amino acids are manufactured to exceptionally high purity standards for consistent quality.
