Why is taurine in energy drinks?

Taurine was added to energy drinks for its mild neuroprotective and cardiovascular effects, not as a stimulant. It has no stimulant activity — it's actually calming (mild GABA-B agonist). Red Bull contains ~1g taurine, within the effective supplemental range.

How much taurine should I take per day?

1-3g/day for general health benefits. Up to 6g/day has been studied without adverse effects. Split dosing (morning + evening) maintains stable blood levels. Evening dose may improve sleep quality. Most of the longevity research used 1-2g/day.

What did the 2023 Science paper say about taurine?

Iyer et al. 2023 (Science, Columbia University): taurine deficiency is a driver of aging across species. Blood taurine declines 80% from youth to old age in humans, mice, and monkeys. Supplementation extended median lifespan in mice by 10-12%. In middle-aged monkeys, improved bone density, muscle, immune function. In humans, higher taurine correlated with lower BMI, blood pressure, and inflammation.

Why is taurine good for longevity?

A landmark 2023 study in Science found that taurine levels drop 80% from youth to old age across multiple species, and that supplementing taurine extended healthy lifespan by 10-12% in mice. It also improved multiple aging biomarkers in primates and a human pilot study.

How much taurine should I take per day?

1-3g daily is safe and effective based on current evidence. Energy drinks typically contain 1g per can. For longevity and cardiovascular benefits, 2g/day is a common protocol. Taurine is well tolerated up to 6g/day.

Does taurine have any side effects?

Taurine is one of the safest amino acids. No significant adverse effects have been found at doses up to 6g/day in clinical trials. It's naturally produced by the body and found in meat and fish. Suitable for most people including those with cardiac conditions.

Can taurine improve athletic performance?

Yes — taurine reduces exercise-induced oxidative stress and muscle damage. A 2018 meta-analysis found taurine supplementation significantly improved VO2max and time to exhaustion. It works particularly well as a pre-workout ingredient at 1-2g.
