7 Surprising Benefits of Taurine
Articles by ProSource
By Dwayne Jackson | Jul 6, 2011
Recent Research Puts the Spotlight on a Versatile Super Amino
Up until recently, support for taurine as an
has not been a hot topic in research journals and bodybuilding forums, but recent developments suggest that is about to change. Indeed, the latest science shows that taurine can significantly
in many different ways. The following article aims to uncover the latest science behind
and muscle performance.
The name taurine is derived from the Latin word Taurus (meaning OX), because it was first extracted from OX bile; but today it is made synthetically. Taurine is a conditionally
essential amino acid
derivative of the sulfur containing
amino acid cysteine
and is chemically described as 2-aminoethanesulfonic acid. It is considered conditionally essential because it is depleted under conditions of heavy physical stress (e.g., during training). Next to
, taurine is the second most abundant
found in skeletal muscle (especially in fast twitch fibers), which has provided motivation for the numerous scientific studies presented in this article. Although taurine exists in most mammalian cells, it is found in high concentration in bile, in the intestines, and in tissues that have high metabolic rates (e.g., heart, brain, and skeletal muscle).
Taurine helps you focus
Taurine exists in very high concentration in the brain and plays a neuromodulatory role in this area. Taurine alters the actions of inhibitory neurotransmitters like GABA , which is suggested to be the mechanism for
noted with taurine supplementation. Of importance to bodybuilders, taurine-based energy drinks have been shown to increase brain performance, focus, and time on task [2, 3].

decreases in strength. Interestingly, supplementation of taurine augments muscle taurine levels and
increases muscular strength
. It has been shown that 2 weeks of taurine supplementation increased rat fast-twitch muscle taurine content resulting in increased muscle force production,
and increased muscle function in recovery . Mechanistic studies have shown that, when a muscle is stimulated, taurine enables more calcium to be released (inside muscle cells) leading to more forceful contractions [4, 5].
Taurine increases muscle cell volume
Taurine is a well-researched regulator of cell volume, as it acts as an osmolyte (i.e., it regulates fluid balance) . As such, taurine works to
optimize cellular hydration
and maximize muscle function. Thus, taurine has been implicated to be a potent cell volumizer. Not only does this make the muscle belly appear more full, but also provides an indirect stimulus for anabolism.
Taurine is anti-catabolic
In a recent study, taurine was shown to exhibit
significant reductions in muscle breakdown
by decreasing catabolic 3-methylhistidine by 20% after intense treadmill running. In the same study, post-exercise urinary excretion of creatinine and creatine were significantly reduced with taurine supplementation, further illustrating its abililty to blunt muscle breakdown .
Taurine regulates blood sugar
There are several studies that show taurine supplementation can regulate blood sugar levels in the body. A recent study reported that mice fed taurine for 30 days saw increased glucose tolerance and insulin sensitivity when given high glucose in their diet . As well, in a recent medical review , it was concluded that taurine supplements may help increase insulin sensitivity and help regulate blood sugar levels.

Taurine extends your workouts
is important to all athletes, including bodybuilders. After all, the harder your muscles can be pushed without overtraining, the greater the anabolic response. Two weeks of taurine supplementation has been shown to increase run time to exhaustion by up to 50%. This effect on muscle endurance correlates with increased/maintained taurine levels, in contrast to a drop in muscle taurine levels with no supplementation [9-12].
Taurine increases recovery
Science has repeatedly shown that taurine is a
and membrane-stabilizing agent. Exercise stress destabilizes and damages muscle cells by a number of different mechanisms, including oxidative stress ; the antioxidant properties of taurine can ameliorate these adverse effects. Taurine has also been shown to reduce inflammation associated with cellular damage. Based on taurine's protective properties, research has shown that this supplement can defend against exercise induced muscle damage and

depletion via supplementation
As you can see, taurine supplementation can benefit nearly all aspects of training including workout intensity, performance, and recovery. Since it is proven that exercise depletes skeletal muscle taurine stores, especially in fast twitch fibers, then it makes sense to add this to your pre- and post-workout supplement regimen. Fortunately, taurine is a fairly common component in pre-workout and amino acid supplements.
As always, of course, it pays to seek out supplements that contain this versatile super-amino in sufficiently high-quality, bioavailable form and in dosages consistent with those used in research. Here at Prosource, we feature a number of products with significant taurine content, including the landmark pre-workout pump complex and cell volumizer SythaTrex Xtreme, the multi-pathway anabolic/anti-catabolic Aminodrol, and the highly regarded amino specialty product Mega Taurine. Each will put you well on your way to experiencing the many physique-enhancing qualities of taurine!
