How people get it: Sold as a supplement and added to energy drinks.
The basics
What it is
Taurine is an amino acid.
How it's thought to work
Taurine is thought to help the heart by regulating calcium, lowering blood pressure, and acting as an antioxidant and anti-inflammatory.
What the research has found so far
The same review found taurine raised the heart's pumping measure (ejection fraction) in heart failure patients. A review of studies in female athletes found taurine, caffeine, and beta-alanine could improve aerobic tests.

On Taurine and aging, PubMed lists 8 trials in people, 13 studies that watched people over time, 323 animal and lab studies. See the counts and searches
Stage 2 because there are 8 published trials and 198 registered trials in people, but no large ones yet.
A stage shows how far research has got, not whether it will work for you. How stages work
Side effects and risks
A review of studies reported no significant adverse effects compared to controls.
Who should be careful, and drug interactions
A review of studies found that higher taurine levels in samples from colorectal cancer patients were linked to higher odds of colorectal cancer.
Amounts used in studies
What studies or labels describe, not a recommendation.
A review of studies looked at dose effects using the total taurine dose given during treatment.
Roughly what it costs
The 3 products we list that contain Taurine cost from $19.95 to $34.49, as read from the makers' pages. See the products
Questions to ask your doctor
- Is Taurine a sensible option for me, given my health and the medicines I take?
- Could Taurine interact with any medicine or supplement I already take?
- What side effects should I watch for, and when should I stop or call you?
- Supplements aren't checked by the FDA before sale. Is there a brand or a third-party test seal you would trust?
- How would we tell whether it is helping, and when should we review it?
This is general information gathered from the sources listed, not medical advice. Talk to your doctor before starting anything new.

Taurine, a darling of longevity seekers, is found to be unreliable biomarker for aging ↗
“Vijay Yadav warned people not to start downing taurine — an amino acid abundant in plants, animals and some energy drinks — just because his mice and monkey study suggested it might be an elixir for long life.”
A new study finds taurine levels rise over time, making it an unreliable biomarker for aging and casting doubt on earlier longevity claims.
