Taurine: The Good, the Bad, & the Ugly

Posted By on Mar 23, 2014 | 3 comments

Taurine SupplementTaurine. According to its proponents, the amino acid is practically a "wonder drug," with benefits ranging from enhancing your workout and mental focus to improving heart health and treating epilepsy. Primarily, you'll find taurine in energy drinks like Red Bull, NOS, Monster, and Rockstar, but it's also in  some pre-workout supplements and even baby formula.  You'll also find taurine abundantly in your own body and in many meats and fish. So what is taurine, and, more importantly, is it bad for you? Let's find out the Good, the Bad, and the Ugly on Taurine.

First the Facts:

Though it was first isolated from Ox bile over 185 years ago, conclusive studies of Taurine for its proposed benefits have remained elusive. It is an amino acid which is considered a conditionally essential amino acid. The "conditionally" is added because infants younger than six weeks can't produce taurine naturally, whereas the rest of us in healthy conditions can (as long as we're getting our B vitamins).  Second only to glutamine, taurine is an abundant amino acid in the muscle amino acid pool.

Now what does taurine do? Some claims are up for debate, but having a depletion of taurine has been linked to developmental defects, immunodeficiency, impaired cellular growth and the development of chronic diseases of the heart muscle. Thus the reason for its conditionally essential status and why you'll find an abundance of taurine in breast milk.

The Good

What taurine is most purported to have beneficial effects for alertness and in enhancing exercise to some degree. Let's see how those claims measure up.

The use of taurine in energy drinks: Primarily advertised in energy drinks like Red Bull for increased cognitive response, taurine has been found wanting in a study by Giles and colleagues1. In this study, caffeine was the main culprit for an increase in mental focus, not taurine.

Pre-workout and Intra-workout Supplements: A big reason for taurine being found in exercise supplementation is for its effect on balancing water and mineral salt levels. The theory here is that taurine enhances the water content in muscle cells, which can be beneficial twofold 1) that can help endurance athletes keep hydrates especially in the heat 2) coupled with creatine, it can potentially enhance protein synthesis in muscle cells.

Does the theory add up? For endurance events, apparently taurine is beneficial.2 For bodybuilding? Not so much.3

The Bad

As with anything in life, too much of a good thing (or in this case, theoretically good) can be bad. In a double-blind study on College Students about the effects of caffeine and taurine supplementation on the heart, Bichler and cohorts found that the combination of caffeine and taurine (contrasted with taken individually, or a placebo) raised blood pressure at the onset of the study. After a week though, increases in blood pressure ceased.4

So if you have high blood pressure already, be especially aware of energy drinks.


The Ugly

Though there are a few studies, such as those cited here, on taurine and its effects, there really needs to be more research done, especially to better confirm or deny the theorized benefits of the amino acid. The Journal of  The International Society of Sports Nutrition concludes this as well concerning ingredients, such as taurine, found in energy drinks.


Unless your an infant whose not breastfeeding, a vegan, or in an acute hyper-metabolic state, your body is already producing a good deal of taurine. Until the theories behind the claimed advantages of taurine are better substantiated, I don't see the need to use supplemental taurine. However, I also don't see much of a reason to avoid it.

Thus, I'll leave it up to you, my readers, to decide for yourself. What do you think? Is taurine great for exercise or focus for you? Comment below.

    Here is something good from taurine….I found it just amazing. Despite the fact that it is an atypical amino acid and is not part of our proteins it plays so much important roles. Here is a useful link for the how taurine regulates our body functions. The study shows that B12 derived from our mothers regulates liver taurine production that in turn goes in the blood and regulates our function.

    • Thanks for the info Juliet! Looks like Taurine and B12 have some benefits for new borns and those with osteoporosis. Great find!

    Hi Jed – Good read. Thanks! I don’t know if it has something to do with my particular body chemistry or not, but I’ve personally found Taurine to be the best supplement at getting me “jacked” before a workout. I avoid caffeine, so it seems to be taurine alone that’s causing the energy spike. I mostly do heavy weight training, but found that it also helps with my running days. It’s good to know that there aren’t any “known” serious negatives associated with its use yet.
