Why do you suggest taking Sustained Plus Immediate Release L-Arginine away from food? I have seen other brands that suggest taking it with food.

The idea behind taking arginine away from food is that arginine may have to compete with other amino acids found in food for absorption. For example, lysine has been reported to compete with arginine's absorption in the intestine, as well as transport into cells. It also may compete for reabsorption in the renal tubules, resulting in increased arginine excretion (Gaby 2011).
