Taurine: Benefits, Supplements & Side Effects

Quick Summary

  • Taurine, a key amino acid, is integral to our well-being, impacting cardiovascular health, cognitive function, & exercise efficacy.
  • Differing from most amino acids, Taurine doesn't contribute to protein synthesis, yet it is a "conditionally essential" amino acid requiring supplementary intake.
  • Among Taurine's diverse roles are heartbeat regulation, cell membrane maintenance, & supporting central nervous system & eye functions.
  • Studies highlight Taurine's significance in cardiovascular health due to its ability to modulate blood pressure & curtail cholesterol.
  • With its beneficial influence on brain health, Taurine promotes nerve cell growth, & augments mental performance & mood.
  • Athletes can benefit from Taurine supplementation, which has been associated with superior muscle function, diminished muscle damage, improved endurance & overall performance.
  • Taurine's natural sources encompass foods derived from animals such as meat, fish, & dairy. However, the scarcity of Taurine in plant-based sources makes it a necessary supplement for those following vegan or vegetarian diets.
  • Taurine supplements, like Elemental Nutrition L-Taurine & Gen-Tec L-Taurine, have gained favour for their vegan-friendly properties, absence of artificial components, high bioavailability, & gluten-free nature.
  • The ideal timing for Taurine supplementation hinges on individual needs & goals, ranging from morning intake for an energy surge, pre-workout consumption for a performance boost, or evening dosage for enhanced sleep quality.
  • Taurine touts an impressive safety record, with research suggesting its general safety.
  • Potential side effects, such as nausea, headache, and dizziness, are uncommon & typically associated with overconsumption.
  • To sum up, the role of Taurine in human health is paramount, & its supplements offer a viable route to ensure adequate Taurine levels, especially for athletes & those adhering to specific dietary restrictions.


As a sulphur-containing amino acid, Taurine stands as a crucial component in our bodies. This potent compound exerts a wide range of physiological functions, from maintaining cardiovascular health to enhancing cognitive function. This article aims to provide an extensive understanding of Taurine, its benefits, sources, consumption safety, & its unique impact on exercise performance.

The Science Behind Taurine

What is Taurine?

Taurine is a sulphur-containing amino acid. However, unlike most amino acids, it isn't used to build proteins. Instead, Taurine is classified as a "conditionally essential" amino acid - while the body can produce it, external sources are necessary to meet our total body needs.

Biological Role of Taurine

Taurine performs a multitude of functions within the human body. It helps regulate heartbeat, maintain cell membranes, & support the function of the central nervous system & eyes.

Health Benefits of Taurine

Cardiac Health & Taurine

Scientific research supports that Taurine plays a key role in cardiovascular health. It can regulate blood pressure & reduce cholesterol, thereby potentially decreasing the risk of heart disease.

Taurine and Brain Function

Taurine also impacts brain health. It supports the growth of nerve cells & boosts brain function, which can lead to improvements in mental performance & mood.

Taurine's Impact on Exercise Performance

A topic gaining increasing interest is Taurine's influence on physical performance & recovery. Taurine supplementation has been linked to improved muscle function & reduced muscle damage in athletes. Furthermore, Taurine aids in fat metabolism during exercise, which can enhance endurance & overall performance.

Other Health Benefits of Taurine

Apart from these, Taurine can improve eyesight, control diabetes, & contribute to the overall well-being of individuals.

Dietary Sources of Taurine

Natural Sources of Taurine

Taurine is naturally found in various animal-derived foods like meat, fish, & dairy. It's less prevalent in plant-based sources, making it an essential supplement for those following a vegan or vegetarian diet.

Taurine Supplements

With the evolving fitness landscape & increased focus on dietary optimisation, Taurine supplements have gained popularity. They serve as a practical way to ensure adequate Taurine intake, especially for athletes, fitness enthusiasts, or individuals with specific dietary restrictions.

Some popular Taurine supplements in Australia include Elemental Nutrition L-Taurine & Gen-Tec L-Taurine. Both of these supplements are vegan friendly, HPLC tested for quality, free from artificial flavours, colours & sweeteners, highly bio-available & gluten-free.

When to Take Taurine

The optimal timing for Taurine supplementation can influence its effectiveness, with no one-size-fits-all answer. Here are a few considerations:

  • Morning: Taking Taurine in the morning can offer an energizing boost & enhance mental clarity during the day.
  • Pre-Workout: If enhancing exercise performance is your goal, pre-workout Taurine could be beneficial. It may boost endurance, minimize muscle damage, & aid recovery.
  • Evening: Some find that evening Taurine promotes relaxation & improved sleep, by calming the nervous system & priming the body for rest.

Remember, the ideal timing for Taurine depends on individual needs and goals. It's advisable to start with a modest dosage, gradually increasing while keeping an eye on your body's response.

Safety and Side Effects of Taurine Consumption

Understanding the Safety Profile of Taurine

Taurine has an excellent safety profile, & most research indicates that it's generally safe for consumption. However, as with any supplement, it's important not to exceed recommended dosages without consulting a medical professional.

Possible Side Effects

Potential side effects of excessive Taurine consumption could include nausea, headache, and dizziness. However, these side effects are typically rare & occur when the recommended dose is significantly exceeded.
