Nitric Oxide supplements are probably the most popular supplements on the fitness market today. Walk into any health food store that caters to bodybuilders, and you'll see names of products such as NO2, Nitrix, NOxplode, SuperPump 250, NOX, TracNO and many others.
I'm a strong supporter in nitric oxide products to build muscle and there has been some double-blind studies that support the effectiveness of nitric oxide supplements. But with so many Nitric O2 products on the market, how do you know which one works the best for you.
To answer the question of which one would be best for you, let's look at what nitric oxide is. Nitric oxide is a without color gas that's found in the tissues of all mammals. It's actually an organic vasodilator of smooth muscle (but not skeletal muscle). Nitric oxide also performs cell-to-cell communication Nitric Oxide alternatives No2-Max for some metabolic functions and this is how it can be used by the entire body to communicate with other cells.
Natural nitric oxide on its own just lasts briefly in the body. But there is an analog to create this gas, as it occurs when enzymes in your body break down the amino acid called Arginine (l-arginine).
Nitric Oxide has been determined to control the circulation of blood vessels and may actually increase blood flow. It also sends signals between nerve cells, and can function to deliver more nutrition to muscle cells, helping the muscles to increase in size when subjected to stress (that "pumped" sensation from working out).
It really is these large, full pumps that bodybuilders seek when lifting weights. As a side note: Erectile Malfunction (ED) prescriptions work in a similar way to increase blood flow (just that ED prescriptions concentrate on controlling blood flow in a different area).
The MRI company defined this industry when they announced the first nitric oxide supplement. I believe it is still the best nitric oxide on the market, but usually it's also the most expensive. BSN and MHP and Pinnacle and Gaspari also make good nitric oxide supplements, but to me, they don't seem to be to be as effective as the MRI NO2, although I believe different people will have varying results until they find the the one that works best for them.
The way to tell which nitric oxide supplement will work best for you is to use one for 6 weeks. In about 2 days of by using a nitric o2 supplement, you should be able to feel a "pump" after your work out and you'll be informed of the feeling throughout the day as you still feel "pumped. " It's kind of like that "tight" feeling you might feel the first a few minutes in the morning after coming, before your muscles have had a chance to stretch.
If you may feel "pumped" and also have a renewed desire to return to the gym each morning after 6 weeks of trying a nitric oxide supplement, try a different one. In the event the first supplement you try doesn't get you to that "pump, " you'll probably only need to try one or two others until you get that "good" feeling. Then you can stay to your chosen nitric oxide generator for a long time.
I should also mention possible part effects of nitric oxide. Whilst I haven't heard or seen any serious health side effects, it's possible to have dizziness, some fatigue, headaches or diarrhea, as these would be associated with too much arginine and they'll go away after reducing the quantity of arginine obtained.
