ZMA Fuel by Twinlab Nutrient Profile

  1. Protein (1 g) is usually used in supplements to help repair and build muscle.
  2. Vitamin B6 (as pyridoxine hydrochloride) (10.5 mg) can be found in certain foods, and the human body requires this vitamin to enable it to perform more than “100 enzyme reactions”. According to one study, vitamin B6 possesses the ability to boost the growth hormone immediately after exercise.
  3. Magnesium (as magnesium aspartate) (450 mg) is a type of dietary mineral, and a deficiency in this mineral can lead to a whole host of health problems, and this is exactly what’s happening in some Western countries at present. High blood pressure is one of the results of a low magnesium intake. According to studies, regular magnesium supplementation can help reduce glucose, and offer “significant improvement during physical stress”. Moreover, other studies have noted improved bone mineral density after magnesium supplementation, as well as improved athletic performance.
  4. Zinc (as zinc monomethionine and zinc aspartate (30 mg), just like magnesium is an essential mineral that assists in regulating certain enzymes. It is believed that the zinc leaves the body through sweat during physical exercise, and this probably explains why zinc levels are so low immediately post-workout. It is widely acknowledged that zinc is a formidable aphrodisiac, as well as a potent testosterone booster, especially for men already suffering from zinc deficiencies. One six-month study involving daily zinc supplementation noted immense improvements in circulating testosterone.


ZMA Fuel, contains all the ingredients that other ZMA blends contain + 1. Protein is the extra element featured in this supplement that is seldom found in other ZMA blends. It makes sense to a certain extent because protein helps to repair and build new muscle. The only issue I have… Just how effective can 1 g of protein be?

Moving onto the remaining ingredients…starting with zinc, a seasoned testosterone enhancing ingredient, that is bound to provide spikes in T levels. Vitamin B6 could work in conjunction with protein because this mineral has shown to boost the growth hormone immediately after exercise, and that’s exactly the point where protein gets to work.

And finally, there is magnesium, which has shown to enhance performance.

ZMA Fuel by Twinlab Overall Rating

ZMA Fuel by Twinlab is a quality ZMA blend that also contains protein. But looking at this supplement purely from a “testosterone booster” perspective, it only contains one ingredient that is capable of doing this, and that is zinc.
