L-Arginine Pro 5,500mg + L-Citrulline 1,100mg Powder - Nitric Oxide

In this review of L-Arginine Pro the bottom line is simple: this powder mix is aimed at active people who want a high-potency nitric oxide support in a pleasant, easy-to-use format. The reviewer found the formula notable for its very high 5,500mg L-Arginine plus 1,100mg L-Citrulline combination, which is the single biggest reason to consider it for workout performance and circulatory support. The product reads like a targeted pre-workout and daily vascular support supplement, with added vitamins and marine minerals that broaden its appeal beyond a basic amino acid powder.

• Aquamin marine minerals: A plant-based calcium and mineral complex included for mineral support and potential bone health benefits.

Who It's For

This product is best for active people, athletes and fitness enthusiasts who want a strong nitric oxide support product that can double as a pre-workout and daily circulatory supplement. The high L-Arginine plus L-Citrulline doses make it suited to those who are already familiar with amino acid supplements and want a noticeable potency.

Those who should look elsewhere include people who are highly sensitive to potent amino acid doses or who prefer a single-ingredient L-Arginine product without added vitamins and minerals.
