Taurine allows athletes to perform at their peak and acts as a trigger for high intensity training. L-Taurine is an amino acid that scientists originally discovered in ox bile, but it is actually produced in small amounts within the human body. It is commonly found in eggs, dairy products, red meat, and fish. Taurine is an amino acid that plays a role in neurological development and has antioxidant properties. Taurine is found naturally in meats and fish as well as in a variety of dietary supplements.

Taurine is the second most abundant amino acid in muscle tissue, with glutamine being the first. But it’s not actually part of the muscle tissue. Rather, it’s primarily in the amino acid pool within each muscle cell and is, in fact, not even a component of protein but remains free in our bodies. It does, however, act as the building block of other amino acids.

Many experts consider Taurine conditionally essential because intense exercise as well as other types of stress deplete the nutrient.

Summary

Considered “conditionally essential,” Taurine appears to play a prominent cell-volumizing role. It’s vital to fat digestion, fat-soluble vitamin absorption, brain and nervous-system function, and transportation of electrolytes across cell membranes.
Science

While Taurine generally is the second most abundant amino acid in muscle, in several metabolic conditions, some muscle biologists like Eric Serrano, M.D., have determined that it, not glutamine, is the most voluminous amino represented in striated type 2 muscle fiber! Taurine has several critical functions and can act similarly to Creatine in that it expands your cells by helping the muscle cell itself hold more water, increasing cell volume. For a lifter or bodybuilder, this is significant because expanded muscle cells can boost hydration resulting in a higher rate of protein synthesis and bodybuilders will appreciate the increased appearance of muscle fullness.
Why athletes use Taurine

As both a cell volumizer and an insulin mimicker, Taurine is used to transport key nutrients, such as glucose and amino acids, into muscle cells. Active individuals report these effects enhance gains in muscle size and strength. Taurine is also beneficial during times of increased physical and emotional stress.

Ways that Taurine can enhance Muscle Gain & Recovery:

Decrease muscle-tissue breakdown and increase muscle size and strength

Mimic the actions of insulin and help shuttle amino acids and blood sugar into muscle cells

Ways that Taurine can enhance Mental Functioning:

Help calm the brain and nervous system to combat anxiety

Muscle metabolism

By mimicking insulin, Taurine may shuttle blood sugar and amino acids into muscle cells, ultimately playing a prominent role in cell volumizing. What this means is simply that cells become “super-hydrated,” which research suggests may trigger greater muscle protein synthesis and less muscle protein breakdown. This could lead to enhanced muscle size and strength.

Brain and nervous system functions

Taurine helps create nerve impulses by aiding the transport of potassium, sodium, calcium, and magnesium in and out of our cells. Thus playing a key role in brain and nervous-system function and blood-pressure regulation. It’s also an inhibitory neurotransmitter or calming chemical messenger and cell membrane stabilizer, which means it helps calm the brain and nervous system and may help treat anxiety, epilepsy, and other excitable brain conditions and is considered a mild sedative.

Research

Reduce Muscle Protein Breakdown
Research has also revealed that supplementing with Taurine may decrease the amount of a chemical marker called 3-methylhistadine (3-MH), which is a telltale sign that Taurine appears to help reduce muscle protein breakdown.

More good news

Recently, supplemental Taurine’s been found in research to have some very promising potential effects for people who have suffered from heart failure. Heart failure occurs when the heart can’t pump blood throughout the body efficiently. Taurine appears to enhance the contractile action of the heart, so it pumps more forcefully. Some experts suggest Taurine may also help lower blood pressure, although research has not yet supported that contention.

Taurine is also vital to the proper digestion of fats, absorption of fat-soluble vitamins, and control of cholesterol levels. Some studies have indicated Taurine’s effect on lowering cholesterol in the liver and thinning bile may also make it effective for preventing gallstones.

As a component of white blood cells, Taurine is also involved with proper immune functioning and the war against free-radical damage.
