Product Description
Step up your brain health routine with a pharmaceutical-grade L-serine supplement. This amino acid is the focus of cognitive health studies around the globe investigating its brain-supporting potential. Your body makes some L-serine naturally, and it’s necessary for the synthesis of the lipids that make up the cell membranes of neurons.*
Neurons are cells in the brain and nervous system that send and receive messages, including sensory information about our surroundings, communicating commands from our brains to our muscles and much more. There are about 100 billion of them and they interact with other cells throughout the body—these critical cells are at the core of our existence.
What is L-Serine?
L-serine is an amino acid. Amino acids are organic compounds that, among other functions, combine to form proteins. All proteins are made up of amino acids and different types of proteins are simply different combinations of amino acids. This particular amino acid is integral to cellular health, especially the health of cells in the brain and nervous system.*
Although L-serine is essential for the body, it isn’t classified as an essential nutrient because your body does make some L-serine on its own. However, dietary sources of L-serine are still necessary for maintaining adequate levels.*
Why Do You Need L-Serine?
L-Serine for Cognitive Health & Overall Wellbeing
An excellent addition to your brain health routine, L-serine is sometimes referred to as a nootropic supplement because it can benefit cognitive function and support mood. Studies are ongoing to better understand the many roles L-serine may play in supporting brain and cognitive health, and it is known that some of the longest-living indigenous people on the planet also consume one of the highest L-serine-containing diets in the world.*
L-Serine for Nervous System Function
L-serine offers many benefits for the health and functioning of the nervous system. Several metabolic functions rely on L-serine, which gets converted to D-serine by the body. Some of these processes include nucleotide synthesis, protein synthesis, neurotransmitter synthesis and more. D-serine is found in high quantities throughout the brain and is known for stimulating the nervous system.*
Other Uses of L-Serine
Although cognitive health is the most popular use for L-serine supplements, researchers say it may also help with stress due to its role in the production of the amino acid tryptophan. Other studies have noted that taking L-serine before going to bed may improve sleep. And since amino acids contribute to immune system regulation, L-serine may also support the immune system.*

COGNITIVE HEALTH SUPPORT
L-serine is an amino acid that is key to the synthesis of phosphatidylserine, a lipid that makes up the protective membranes of neurons and serves as a cellular messenger—it’s needed in high amounts in the brain for healthy cognitive function. Each serving of Swanson AjiPure L-serine delivers 500 mg of nourishing, pharmaceutical-grade L-serine to give the mind a healthy boost. L-serine supports brain health and function, nervous system function and promotes healthy neurons.*
AMINO ACID SUPPLEMENT FOR NERVOUS SYSTEM HEALTH
L-serine provides many benefits for nervous system health and function. L-serine is converted into D-serine, which is found in high concentrations in the brain and stimulates the nervous system. D-serine also plays a role in the synthesis of nucleotides, which are basic structural components of DNA that protect the nervous system, as well as protein synthesis, neurotransmitter synthesis and more.*
500 mg Pharmaceutical-Grade L-Serine per Serving
(per 1 capsule serving)
Features a patented, pharmaceutical-grade L-serine from AjiPure produced through a fermentation process by the amino acid experts at Japan’s Ajinomoto, Amino Science LLC—an extremely high-quality, high-purity amino acid supplement*
