Product Details

Did You Know?

The word taurine comes from the Latin word taurus, which means ox or bull. Scientists initially discovered it in the bile of an ox in 1827. Later, another scientist confirmed taurine also exists in human bile.

What is Taurine?

Taurine is a semi-essential sulfur-containing amino acid that plays a role in antioxidation and is critical for the development and function of muscles. The brain, retinas, heart, and muscles contain the highest concentrations of taurine found in the body.

Taurine is a derivative of cysteine, which the body synthesizes in the pancreas by converting methionine into homocysteine. Unlike true amino acids, taurine is not integrated into proteins. It is the second most abundant free amino acid, with glutamine as the first. Some metabolic actions of taurine include cellular growth, detoxification, membrane stabilization, and modulation of cellular calcium levels.

Meat, seafood, and dairy are the primary taurine food sources, with plants containing negligible amounts of taurine. As a result, vegetarians and vegans often have lower levels of taurine than individuals that consume meat and other animal products. Energy drinks contain high levels of taurine as well.

Taurine can conjugate with bile acids to improve the absorption of fat-soluble vitamins. It exerts antioxidant effects that may promote and protect heart and eye health. It’s also a popular supplement among athletes due to its effects on exercise performance. It may help balance moods as well, particularly in a nervous state.

Potential Taurine Benefits

Taurine as an Antioxidant

Taurine helps regulate cell membrane fluidity, thus aiding the transport of nutrients and enzymes in and out of cells. While it can’t directly scavenge free radicals, it can bind to free ions in the blood. Taurine significantly reduces oxidative stress on heart tissue by protecting it from free radical damage. It also modifies insulin signaling receptors, which helps reduce lipid peroxidation and improve insulin resistance. Taurine also protects and promotes eye health, potentially as a secondary effect of its ability to control prooxidative stressors in the retina. It also acts as an osmolyte in the retinas, which helps maintain and regulate the cellular structure, hydration, and ocular pressure.

Why is Taurine in Energy Drinks?

Taurine isn’t a stimulant and typically has the opposite effect. It may help calm the excitability caused by the stimulants often found in energy drinks. Stressful conditions, such as intense exercise, can deplete taurine levels. Including taurine in a preworkout energy drink may help attenuate this issue.

Taurine Supplements and Exercise Performance

Taurine has several promising properties that may enhance athletic performance. It delays muscle fatigue and improves recovery time. It also helps fuel the body during workouts by increasing how much fat the body burns during exercise. Taurine also increases oxygen uptake and may improve strength and power output. It can help reduce exercise-related muscle damage as well. As an osmolyte, taurine acts as a cell volumizer by regulating fluids. Like creatine, taurine increases the appearance and fullness of muscles by drawing water into muscle cells.

Other Potential Taurine Benefits

Taurine can activate glycine receptors and act as an agonist on gamma-aminobutyric acid (GABA) receptors. Increasing GABA levels can help improve mood, while Taurine’s effect on glycine can help soothe nervousness and unease. Taurine also acts as an anxiolytic by activating glycine receptors. Taurine may improve skin aesthetics as well by maintaining hydration.

Potential Taurine Side Effects

Taurine is safe at suggested serving sizes and up to 3g per day. Some individuals may experience mild nausea, stomach pain, or headaches. Taurine may interact with certain medications. Consult with a physician before starting any new supplements.

Purity and Concentration of Taurine Supplement Powder
