Review on VMI Sports Vasogen Ultra Nitric Oxide Booster: Stim-Free Pre-Workout for Strength, Endurance, and Muscle Building. Vasodilator and Nitric Oxide Supplement with 60 Capsules. by Natalie Villa

I like that it seems to be a more holistic NO booster. I am familiar with hawthorn, pine bark extract and the biologically active properties of berries. Their Vasogen Pump Matrix ingredients are pretty impressive, especially their organic Vitaberry fruit blend. While L-Arginine has shown a rapid increase in NO levels in some studies, there are some downsides that may be associated with its use as a dietary supplement (obtained from food, it is metabolized differently and apparently with no such or potential negative consequences). So I'm guessing they specifically pointed out that it wasn't in their recipe. I took a dose yesterday and today and felt no effect. Perhaps this is a cumulative effect. As a disclaimer, I am already taking supplements that stimulate the NO cycle. So it's entirely possible that my nitric oxide cycle is already optimized/saturated. Assuming this is the reason for the lack of a noticeable increase in nitric oxide levels, I honestly can't fault this supplement. I will find issues with missing certificates/badges such as USDA Organic, GMP and FDA registered businesses. According to the label on the bottle, none of these cases were marked. This problem makes the thing rating. Based on these considerations, this NO booster supplement is rated 3.5-3.75 stars.
