Each capsule gives you 1,000mg of **Taurine** in free-form — right at the floor of the 1,000–3,000mg clinical range studied for cardiovascular and metabolic health. Taking two capsules daily as the label allows brings you to 2,000mg, a dose used in multiple heart-health and blood pressure trials.

Taurine has strong research backing across dozens of RCTs, particularly for heart function, blood pressure regulation, and exercise recovery. The veg capsule format keeps your dosing simple — one or two per day, no mixing required.

The main limitation is dose ceiling. If your goal calls for the higher end of the clinical range (3,000mg), you'd need three capsules daily, which pushes through the bottle faster. At the recommended one-to-two capsules, you're well-covered for general cardiovascular support.
