ProLab Nitro Fire is a bodybuilding supplement designed to increase energy and maximize muscle growth potential. The ingredient list is available from various online companies, but the product is not for sale from the ProLab company directly. When it comes to choosing the right bodybuilding supplement, the consumer wants to know exactly what ingredient are used in the supplement and how much of each ingredient is included. This is not the case with ProLab Nitro Fire. Some of the ingredients are included in a proprietary blend, which hides how much of the ingredients are included in the formula, including caffeine.

List of Ingredients

Vitamin B6, Folic Acid, Vitamin B12, Calcium, Phosphorus, Magnesium, Sodium, Potassium and L-Arginine-Alpha-Ketoglutarate.

ProLab Volumizing Blend: DiCreatine Malate, L-Tyrosine, L-Taurine, Citrulline Malate, Glycocyamine and L-Histidine.

ProLab Power Blend: Glucuronolactone, Betaine Hydrochloride, Caffeine, Guanidino Propanoic Acid, Evodia Fruit, Nicotinamide Adenine Dinucleotide, Gynostemma and Vinpocetine.

Product Features

The initial ingredients in ProLab Nitro Fire are basic vitamins. B vitamins are included for energy metabolism support. These will likely cause a brief increase in energy, but B vitamins are flushed out of the body quickly so the energy will not last the entire day.

L-Arginine is a strong antioxidant that works to fight free radical damage. L-Arginine is also used by the body to boost production of other antioxidants naturally occurring in humans. It is a fat and water-soluble antioxidant.

The volumizing blend includes creatine. Creatine does not increase muscle volume, but it does force water to swell muscles. This causes weight gain in the form of water weight. Bodybuilders tend to take creatine during the building phase and then shed water later for competition.

The Power Blend includes caffeine, a proven energy supplement and metabolism booster. We have no idea how much caffeine is included in the supplement so we suggest dieters taking ProLab Nitro Fire start out with a small dose of the supplement and work up to the full dose to ensure there is not too much caffeine.
