Nitrox II by Sci-Fit is a nitric oxide booster for increased muscle gains and bodybuilding support. The official website lists all ingredients in the formula and amounts for each ingredients. This is a huge positive for Sci-Fit as many companies try to hide ingredient totals to fool consumers. There are only a few ingredients in the formula and all are listed with familiar names. It is common for bodybuilding supplement companies to list common ingredients with scientific names to make the supplement appear more impressive. We like simple and to the point, but do the ingredients really boost nitric oxide?

List of Ingredients

AKG (Arginine Alpha-Ketoglutarate), Citrulline Malate, L-Taurine, Alpha Lipoic Acid and Vanadyl Sulfate.

Product Features

Sci-Fit Nitrox II combines ingredients to increase natural production of nitric oxide and increase cell volume. The two main ingredients in the formula are Citrulline Malate and AKG. Both are used to promote nitric oxide levels, but Citrulline malate goes beyond that to promote increased levels of L-Arginine in the blood compounding the nitric boosting effects. L-Taurine helps increase pump during the workout and Alpha Lipoic Acid helps bring all the ingredients to cells quickly and efficiently. ON the whole, the supplement formula is sound, but the reviews of the product are often more convincing than the ingredient list.

Reviews of Nitrox Ii are spectacular. Users claim they feel a better pump and increased energy when using the supplement before a workout. In addition, on off days when the supplement is not taken, muscles feel stronger and that extended pump tends to carry over.

Weight loss is not supported by any of the ingredients in Nitrox II, so the dieter will not gain the same benefits a bodybuilder or weight lifter would from the formula. The company does not claim to boost metabolism or increase fat burn.

Nitrox II sells for $35.99 from outside websites and $29.99 from Sci-Fit. This is one of the first supplements that sells for less from the manufacturer.

Nitrox II is a nitric oxide supplement that bodybuilders and weight trainers love. The ingredients help the user feel stronger pumps and more energy, which is the sole purpose of the supplement. There are no stimulants in the formula, so energy production is linked to all-natural ingredients. We suggest dieters use a different formula for weight loss as none of the ingredients in this supplement have an effect on metabolism. Green tea, chromium and caffeine are three proven weight loss ingredients.

    I don’t know about the long term effects, but the ad let lead you to believe you have 14 days of trial or your money back is definitely a scam. When they say you have 14 days of trial before you are charged $85.00 for the next product they don’t let you know that your 14 days starts as soon as you order it. My delivery took 9 days to get here I thought I have 14 days from then on, but it appears that I had 5 days to try it in which I hadn’t experienced anything that was promised. So beware before you order this product especially the trail product!
