What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

NutraKey Taurine is a single-ingredient powder containing L-taurine, an amino acid your body makes naturally and also gets from protein foods like meat and fish. Your body uses taurine in several tissues, including muscle, the brain, and the heart.

This product provides taurine in supplement form.

Does it work?

Insufficient evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: muscle performance, strength, and athletic recovery.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle soreness, Physical performance, Postoperative recovery, Muscular dystrophy, muscle endurance — and 3 related terms.
  • The closest evidence on file: Taurine is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Taurine is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Muscular dystrophy, Physical performance, Postoperative recovery.

Evidence suggests taurine may be possibly effective for hepatitis and congestive heart failure (CHF). For obesity, the evidence currently points toward possibly ineffective.

Keep in mind that 'possibly effective' means the research shows some promise, but more study is needed to confirm real-world benefit.

The evidence, ingredient by ingredient Taurine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Taurine is generally well tolerated when taken orally in typical doses for up to one year. The most common side effects are constipation, diarrhea, and indigestion.

Rare serious effects include allergic reactions in people sensitive to sulfur-containing compounds, though most concerning reports have involved energy drinks with multiple ingredients, making it unclear whether taurine alone was responsible. Long-term safety beyond one year is less certain, and there isn't enough reliable safety data on supplement doses — use only under medical guidance.

Taurine occurs naturally in breast milk, but the safety of taurine supplements during pregnancy and breastfeeding hasn't been well studied, so talk with your doctor or pharmacist before taking it if you're pregnant or nursing.

The bottom line

Scorecard at a glanceFully disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

NutraKey Taurine may help with hepatitis or heart failure, but the evidence is still preliminary. If you take blood pressure medications or lithium, you'll want to clear this with your doctor or pharmacist first.

For long-term use or if you have any health concerns, use this product only under medical guidance.

Formula

The second most abundant amino acid in muscle after glutamine Taurine has been known to increase muscle mass, muscle strength, and power, reduce muscle damage caused by exercise, accelerate recovery between workouts, and help to load essential nutrients into muscle. High concentrations of taurine are important for performance athletes Many studies have been performed on the health benefits of taurine. A two week study involving taurine depletion methods of intense and exhaustive exercise revealed that subjects who supplemented taurine did not have any depletion of the amino acid in their body. Taurine differs from most other amino acids This is because taurine is not incorporated into proteins. However, it does play many significant roles in the body including bile acid conjugation, detoxification, membrane stabilization, osmoregulation, modulation of excitatory neurotransmission, and intracellular calcium levels. The average taurine intake in humans is estimated at 60 mg daily. With supplementation, you can far exceed this amount and readily increase taurine levels in many tissues, which leads to enhanced physical performance.
