NitroTech protein, a MuscleTech product, is a sports nutrition supplement primarily composed of whey protein concentrate along with such ingredients as creatine, cocoa powder and amino acids. Available in seven flavors, NitroTech protein can help build muscle but may also cause side effects. Consult a doctor before using NitroTech or any other supplements.

Gas and Bloating

The primary ingredient in NitroTech protein is whey protein concentrate, a protein source derived from dairy. This concentrate, along with all other dairy products, contain a sugar called lactose. Some people cannot properly digest lactose, a condition known as lactose intolerance. This may cause gas and bloating between 30 minutes and two hours after ingestion.

High Blood Pressure

One of the added ingredients in NitroTech protein is creatine, an amino acid that can improve your workout performance. This happens because your body can convert creatine into ATP, or adenosine triphosphate, a cellular energy source. While creatine can be beneficial, the University of Maryland Medical Clinic, UMMC, explains that supplementation of creatine may cause some side effects, such as high blood pressure.

Kidney Damage

Due to the high protein content and inclusion of creatine, NitroTech protein may cause or increase the severity of existing kidney damage. High-protein diets can cause or aggravate kidney damage, according to nutritionist Katherine Zeratsky, R.D., L.D. Each serving of NitroTech contains half the daily suggested intake of protein and MuscleTech recommends consuming three servings each day, which would deliver 150 percent of your daily protein requirement. Additionally, UMMC suggests that creatine may cause kidney damage.

Liver Dysfunction

Another risk of high-protein diets is the potential for liver problems, according to UMMC explains that creatine use may also cause liver problems; thus, continued use of NitroTech may increase your risk of liver dysfunction.


NitroTech use may bring nausea, as creatine can trigger this effect. Also, if you are lactose intolerant, the whey protein concentrate may cause nausea as well. In addition, notes that soy lecithin, another NitroTech ingredient, may cause nausea. In some cases, it can also cause a severe allergic reaction that includes hives, swelling of your face and tongue or difficulty breathing.
