By increasing nitric oxide output, you’ll be able to deliver more nutrients and oxygen to the muscles, which improves the muscles’ ability to handle the extra physical demands placed on them during weight workouts and to build and recover under those intense conditions.
Recently, in a double-blind randomized placebo-controlled study, researchers at Hiroshima University in Japan looked at pycnogenol’s effect on NO release and the amino acid L-arginine. After subjects took 180 milligrams of pycnogenol for two weeks, the researchers reported a 42 percent increase in blood flow, citing acetylcholine stimulation
Other studies have found that pycnogenol can improve endurance by 21 percent at doses of 200 milligrams daily.
