What's the big deal with Nitric Oxide?

    I go to a few bodybuilding sites and also subscribe to a couple of fitness magazines. I see ads for nitric oxide products and wonder what the big deal is. Why do people take it and what does it do? When I read the marketing copy for these products it all seems like a bunch of BS trying to sell you the product based on the assumption that you'll get really big. Somehow this comes off as a miracle muscle growing product which we all know is not true. You have to work hard to get a great body. I just wanted to get some opinions on this. Thanks for any feedback!

    Never heard that it would be of any use for sports.
    It can be used to widen the blood vessels though. People living in high mountain regions sometimes have higher percentage of NO, cause that way there can be more oxgene in their blood. Guess some companies might reinterprete that and tell you to need it for better oxygene supply.
    What are they promising on those ads?

    Pretty much BS.

    The nitric oxide and muscle growth is nothing more than a theory. No facts just marketing.... And to be honest im not sure there is any NO in the product they are selling, NO precursors are prescription drugs, and not dietary supplements.

    Nitric Oxide has proven benefits to anyone who lifts very heavy on a regular basis - e.g. someone doing High Intensity Training five days a week for an hour or more each day. The benefit is three fold:
    1. Increasing blood circulation, thus pushing more blood into the muscle for a better pump. There's more to a good pump than the feel, as the increased blood pushed into a muscle is part of the process of triggering adaptation and anabolism within that tissue. Pushing blood also aids in faster ATP recovery. This means you push heavier weight for longer periods of time, and you only grow bigger if you grow stronger. Can't get one without the other.
    2. Nitric oxide triggers the release of adrenaline, giving you, once again, greater strength during heavy lifting.
    3. Increased oxygen within muscle tissue aids in recovery, and can let you workout with greater intensity more often and for longer periods of time.

    The studies that have been conducted, and published, have monitored subjects involved in both resistance training, and endurance training, and the benefits to both groups are evident in all clinical studies conducted since as early as 1996. Measurable, and frequently impressive, increases in dense, lean muscle tissue have been experienced even in control goups dosing at very low levels. And, unlike steroids, the gains are maintained as long as the subject continued their same level of training intensity.

    Loading it is tricky, as you have to determine your tolerance based on slowly increasing intake over a period of five days. NO is created through the conversion of L-Arginine which you can consume too much of, resulting in fatigue, gastritis and nausea. It is most beneficial if taken twenty to thirty minutes prior to intense training, and on an empty stomach.

    Not everyone can tolerate it, and most of the commercial products on the market contain added stimulants - caffeine - in order to increase the jacked feeling subjects get, and the "focus". There are a few that do not contain stimulants.

    It also appears to help in pushing pre-workout creatine into the muscle, as well, so that's a bonus, and the reason many NO products contain some creatine.

    Not true, Doc. The NO precursor is Arginine.
    Arginine -> Nitric Oxide -> Vasodilation -> Nutrient Delivery -> Muscle Growth and Strength
    However, this only works on healthy subjects who have been fasting, thus the reason for dosing on an empty stomach.

    So a lot of guys who work out after they get off the job do not truly have an empty stomach. The product can work, if you have been fasting (overnight) and you load properly. The research papers are all out there, clinical trials conducted by U.S. and U.K. universities of good reputation, not funded by supplement manufacturers.

    Is it Joe Gym-Rat's best choice? Probably not. But there's science to show its efficacy.

    NO is a radical and therefor pretty short-lived (up to ~3sec). It is used for information transduction in many ways in the human body. Sure, some of these are good for muscle-growth, but the NO would have to get there to be active and in that life-span that's just about 200 ┬Ám away from where it is formed.
    The body clearly wouldn't want to have signals triggered just by food also, so I vote for BS.

    Insulin (which is legal, and WORKS) is VASTLY more effective at getting nutrients into the cell. (For you funky folks: this is not an endorsement of any kind, but, a statement of FACT.)

    If you want a pump, do higher reps.

    More than anything, NO supplements are junk.

    If you wanna lower your blood pressure and have some vasodilation, do cardio, or grab some poppers. Lots cheaper, and more fun.

    I'm with Krovi on this one.

    I do sports, and i think it is of good use.

    Krovi saidIt can be used to widen the blood vessels though.


    I know at first sight that vasodilation seems to be useless for sports but its not.

    NO products have Arginine and that's why i use it.

    when I'm tired 2nd workout of the day on the track... pre-workout supplements and caffeine get you up and the pump caused by NO is noticeable. and I find it easier to work harder with "NO" products and that pump... mind you i only use em when I'm "down".

    supplements with L-Arginine are useful tools.

    and not all of us can use insulin chucky lol we just pound sugar icon_razz.gif

    I've been using N.O. supplements for a couple of years now. I like it. Works for me. It's not a miracle muscle growth supplement at all. As others have pointed out, the primary benefit is improved blood circulation. Better circulation, means more nutrients and oxygen flowing to your muscles. Also, better muscle pumps. But like all supplements out there, it may not work for some people.
