Taurine is a sulfur-containing amino acid. Most bodybuilders don’t realize that it is the most abundant free amino acid found in heart muscle, skeletal muscles, nerve, brain, and many other organs. Taurine affects many diverse electrophysiological and biochemical parameters within muscle.
The Importance of Taurine for Muscle Gains is Emerging From The Research
The content and transport of taurine is rapid in both slow and fast twitch fibers. It has been reported that taurine stabilizes the intracellular membrane of many cells to help modulate nerve excitement during muscle contraction.
Some research demonstrates taurine’s ability to alleviate or prevent muscle cramping during and after exercise, further evidence of taurine’s intimate role in muscle contraction.
Taurine is also a powerful regulator of muscle cell volume. Its osmotic properties are second only to the amino acid glutamine. Increasing and maintaining a muscle’s fluid content (cell volume) is a potent trigger of muscle building mechanisms such as protein synthesis and glycogen accumulation.
Recently published research suggests that weight training may tax muscle taurine stores more severely than previously suspected. A training study on rodents revealed that exercise significantly decreased muscle taurine levels, regardless of duration or intensity.
Also, this depletion of taurine was more pronounced in fast twitch biceps muscles fiber. This is bad news as these are the bodybuilding fibers most responsible for dramatic size increases. Supplementation with taurine may be of benefit.
Each capsule of taurine provides 1000mgs of taurine. Using creatine with taurine directly before and after intense exercise will help maintain muscle taurine levels and keep the cell in a “volumized state”. Taurine most likely creates a synergy with other key components to increase and maintain cell volume for a consistent period of time. This appears to be an important aspect for triggering the synthesis of new contractile tissue within muscle.
