Boosted Flow is the product in this round-up whose name, mechanism and ingredient list line up most closely with each other, which in this category counts for a lot.
Nitric oxide relaxes the smooth muscle in blood-vessel walls, which widens the vessel and improves flow. Amino acids like L-citrulline raise the body's nitric-oxide availability. This is not a fringe claim — it is standard physiology, and it is why citrulline shows up in sports-nutrition research repeatedly.
The trials that found real effects on exercise performance used several grams of citrulline per day. That is a lot of powder, and plenty of formulas include a fraction of it while borrowing the credibility of the research. When you land on the page, look for the milligram figure and hold it against that bar.
