The amino acid L-arginine is involved in many vital processes in the body, from detoxification to energy production, but it is in circulatory health where it has its greatest impact. L-arginine is a key player in the body's production of nitric oxide, a compound that helps keep blood vessels dilated to promote blood flow and help maintain blood pressure already within a normal range. This makes L-arginine beneficial for overall cardiovascular maintenance and in areas such as sexual function that depend largely on circulatory status. Our Arginine AKG Powder delivers a super-potent 5 grams per serving--a much higher dosage than other forms. It features a delicious natural lemon flavor and dissolves readily in water to create a great-tasting nutritional drink.
