ZMA

ZMA is a vitamin complex of zinc, magnesium and vitamin B6. An increase in exercise can lead to the loss of vitamins and minerals making it particularly important for bodybuilding due to the blood sugar level rises and urination increases, increasing the loss of magnesium, zinc, B12, B6, folic acid, and many other nutrients.

Basically ZMA is a supplement to replenish vitamins. In some studies ZMA helped overall strength and has raised testosterone, which is vital to muscle formation. I don't take ZMA, because I eat a varied diet with many fruits and vegetables. Like - spinach, milk, blueberries, strawberries, oranges, grapefruits, broccoli, fruit juices not from concentrate without added sugars, soymilk, and lean meats. Eating a varied diet and supplementing with a multi-vitamin powder/mix helps ensure your body is at its peak ability to build the muscle that you deserve.

Nitric Oxide (NO) Boosters.

Most NO boosters have one thing in common: their active ingredient is arginine. However, they usually contain a whole host of ingredients that bump up the effectiveness of L-Arginine. Nitric oxide, a gas produced naturally in the body, is responsible for numerous processes, but the most important for bodybuilders is vasodilation: NO causes the smooth muscle cells of blood vessels to dilate, allowing more blood to flow through. The more blood flow, the more oxygen, nutrients and anabolic hormones your museles can get to fuel workouts, repair post-workout damage and ultimately grow.

NO-boosters are mainly used by avid weight-lifters and body builders to achieve more "pump" (blood vessel dilation causing more blood flow to muscles). Personally, I take little to no NO boosters for my regimen. Sometimes, the creatine compound I drink has 1 gram of L-Arginine (NO booster). I haven't really been able to tell the difference when I've used it. If you are really enthusiastic about about beginning a strict training regimen, I recommend you try this a 2 months after implementing whey-protein, casein protein, glutamine, and creatine into your nutrition. In the meantime, more blood flow can be achieved through pre- and post- workout stretching, and great lifting technique.
