Calm, steady energy and focus that doesn't feel wired, with support for your workouts and recovery.
- Calm, steady energy. Focus without the edge, and a smoother cup of coffee.
- Workout performance and recovery support. Taurine has been studied for endurance in active adults (see Research).
- Cellular hydration and electrolyte balance. Taurine helps move potassium, sodium, calcium and magnesium in and out of cells.
- Restful evenings. Many people like it later in the day too.
Why it fits bioenergetic living. Taurine is one of the most abundant free amino acids in your heart, muscles and brain. It's a calming cousin of glycine, so it gives you steady energy without stimulants, the way people eating for energy like it. One clean ingredient.
A 2023 study in Science found taurine levels naturally fall with age. See the Research tab.
Why Ajinomoto taurine:
- Ajinomoto taurine, made in Omuta, Japan. From the world's leading amino acid brand, and it meets USP.
- Bought directly from Ajinomoto. Ajinomoto's spec is 98.0–102.0% pure, with tight low-toxin limits: heavy metals 10 ppm or less, arsenic 2 ppm or less. See the Typical Certificate of Analysis (PDF) in Quality & Sourcing.
- The best taurine we've found.
- Just taurine. Pure white crystals, no fillers, no blend. Dissolves in water. Scoop in the bag.
200 g if you're new to it, 800 g if you already use it. 60-day no hassle returns.
Start low. 500 mg (2 heaping .15cc scoops) once a day, in water or under the tongue. For an exact amount, use a precision digital scale.
Raise slowly. After a week or so, move to 500 mg twice a day (the label serving).
Signs to ease off. If you feel off or your stomach is unhappy, take less and talk with your healthcare provider.
Store cool, dark and dry.

Taurine: what the research shows
Taurine is one of the most abundant free amino acids in the body, found in high levels in muscle, heart, brain and eye tissue. These studies cover taurine in general, not this exact product.
A "very essential" amino acid

Physiological roles

The classic review, including taurine's role in moving electrolytes across cell membranes.
Heart and muscle

Endurance performance

Across studies, taurine improved endurance performance.
Healthy aging

Taurine levels fall with age; in animals, taking taurine supported healthier aging.
Bioenergetic & low-toxin perspective
Ray Peat grouped taurine with glycine and GABA, the body's calming amino acids.
"Another type of amino acid, taurine, is structurally similar to glycine (and to beta amino propanoic acid, and to GABA)…" — Ray Peat, "Gelatin, stress, longevity" (https://raypeat.com/articles/articles/gelatin.shtml)
"Glycine is recognized as an 'inhibitory' neurotransmitter, and promotes natural sleep." — same article
A study Peat cited in that article: Zhong Z, et al. (2003). L-Glycine: a novel antiinflammatory, immunomodulatory, and cytoprotective agent. Curr Opin Clin Nutr Metab Care 6(2):229-40. PMID 12589194. A review of glycine's calming, cell-protective roles, which taurine shares in part.
