What are L-Valine capsules?

The L-valine powder in these capsules is an essential amino acid required for the smooth functioning of the nervous system and to aid muscular development in the body.

L-valine is one of the three Branched-Chain Amino Acids (BCAAs). The other two are L-leucine and L-isoleucine.

"Branched chain" refers to a chemical structure setting BCAAs apart from other amino acids. Up to 25% of total protein dietary intake are BCAAs, used by the body to promote the healing of injured tissues and to protect against muscle tissue breakdown (catabolism) during exercise.

BCAAs are the single most important group of amino acids for just about anyone, from world champion athletes to regular people. BCAAs comprise one-third of all the protein in muscles.

L-valine specifically helps maintain nitrogen balance in the body, essential for muscular development.

L-valine is an essential amino acid because it cannot be manufactured by the body and must be obtained through food or dietary supplements.

L-valine and the other BCAAs are not processed in the liver. They are metabolized in the muscle, directly and significantly influencing muscle-protein metabolism and aiding recovery after intense exercise.

The production of glucose for energy during intense physical activity is supported by L-valine, reducing muscle breakdown.

L-valine also influences the brain's uptake of neurotransmitter precursors tryptophan, phenylalanine, and tryosine.

Valine helps eliminate potentially toxic excess nitrogen from the liver and transports nitrogen to other parts of the body where it is needed.

Athletes who train or exercise frequently or have a low-protein diet should consider valine supplementation. Although it is available in stand-alone supplemental form, it should always be taken together with the other two branched-chain amino acids, isoleucine and leucine.

The correct balance is 2:1:1: two parts L-leucine and for every one part of L-valine and L-isoleucine.

Studies have shown BCAA to be helpful in other areas due to what each amino acid does in its own right. For example, leucine is necessary for wound recovery to skin and bones and helps protect muscles, valine helps promote or maintain nitrogen balance (essential for muscular development), and isoleucine helps boost energy and is necessary for forming hemoglobin.

Some natural sources and food products that contain L-valine include meat, leafy vegetables, mushrooms, peanuts, soy protein, kidney beans, poultry and milk.

Health Benefits of L-Valine

L-valine is needed for muscle metabolism, tissue repair and the maintenance of a proper nitrogen balance in the body. It can be used as an energy source by muscles.

L-Valine is typically taken (with the other BCAAs) by weightlifters and performance athletes. Blood levels of L-valine will fall significantly after strenuous exercise and will stay low until complete recovery occurs. Supplementation with L-valine one hour before strenuous workouts can reduce the recovery time by increasing muscle protein synthesis and counteracting catabolic processes.

Purity and Concentration of L-Valine

The pharmaceutical-grade amino acid powder in these capsules contains no fillers, taste additives or anti-caking agents. Vegetarian capsules are made of cellulose. Gelatin capsules are from a bovine source.

Suggested Use of L-Valine

As a dietary supplement, take 2 to 4 capsules once or twice a day, depending on individual needs, together with the same amount of L-isoleucine and twice as much L-leucine. Some athletes use larger amounts based on individual preference or the recommendation of a professional trainer.

PureBulk also sells the three branched-chain amino acids (BCAAs) as a blended powder product and in a blended capsule form.

Potential Side Effects of L-Valine

L-valine is safe at suggested serving sizes. Too much valine in the diet can disrupt liver and kidney function by increasing the amount of ammonia in the body. People with impaired liver or kidney function should not take isoleucine without first consulting a physician. It is not recommended for women who are pregnant or nursing.

How should I store it?

You will receive these capsules in a resealable bag. Store in a cool, dry, dark location. Reseal tightly between uses.
