Ok folks, this post was requested today at the box. Many of you have heard of Nitric Oxide (NO) and have tried various NO products to increase vascularity. The reality is that NO is a very useful bi-product of the breakdown of the amino acid L-Arginine. It has been used to treat a wide range of physical ailments and has gained quite a reputation in the last few years with some compelling scientific studies emerging validating its efficacy. Athletes have found that the increase in blood flow has the capacity to increase output. Does it really help? Is it worth it? I think that results will vary depending on dosing and age. There is a lot of evidence that a low dose of L-Arginine (anything under 6 grams) will not have a profound effect. There’s no doubt that L-Arginine is legit. But if you’re interested in giving it a shot, do your homework; find a really good quality product. Here’s a link that can provide a nice baseline for a better understanding of L-Arginine and the role that NO plays on a biochemical level.
