Toro! Toro! Olé! Good morning, endurance friends. Matt Mossman, the endurance guru over at EndurElite, coming at you with another endurance fast fact.

Today, we're going to talk about the supplement, taurine, which is in our PerformElite Pre-Workout, and how it can benefit your endurance performance.

The Biggest Myth About The Supplement Taurine. It's not made of bull sperm

But, before we get to this, or that, there's a myth out there that taurine comes from bull semen.

  • One, ew.
  • Two, it actually was first identified in bull bile.
  • And three, nowadays, luckily, we don't have to go out to the pasture and romanticize a bull to get our taurine.
Instead, it's made from the amino acids, cysteine, and methionine.

No Bull. Taurine Supplementation Benefits Runners, Cyclists, and Other Endurance Athletes

So, how can taurine benefit endurance performance? There are a few ways. There's a bunch of them, but we'll just cover three, real quick.

  1. One, taurine can increase insulin sensitivity, meaning, it helps keep blood glucose within normal ranges.
  2. Two, taurine can prevent muscle breakdown, it can prevent lactic acid buildup, and all around, it's just good for muscle function. Taurine is found in skeletal muscle, and a lack of taurine can compromise skeletal muscle function by approximately 80%, which is really significant.
  3. Three, taurine can help promote angiogenesis, or the formation of new blood vessels, specifically capillary vessels, where a lot of nutrient and oxygen exchange occurs in the body, especially during exercise. So, with more blood vessels, oxygen and nutrients are delivered more efficiently, and you can perform endurance, exercise a lot, lot better.
