For blood flow and cardiovascular support, the suggested two tablets daily give you 2,000mg of **L-Arginine** — right at the bottom of the 2,000–6,000mg clinical range. That's enough to reach the minimum effective threshold, but most research showing clear benefits in exercise performance and circulation uses 3,000–6,000mg per day.
The form here is L-Arginine HCl, a standard and well-absorbed form. Each tablet delivers 1,000mg of free-form arginine, so you have flexibility to scale your dose up to 3–4 tablets if your goals require it — just note the label suggests taking them between meals or at bedtime for better absorption.
The label suggests taking tablets between meals or at bedtime for better absorption, and the 120-tablet bottle gives you a 60-day supply at the two-per-day dose. If you're also on blood pressure medication, check with your doctor before starting — arginine can amplify the effect of antihypertensives.
