Battle of the Testosterone Boosters! ZMA vs. Tribulus
Testosterone is vital for muscle growth and for decades natural bodybuilders and athletes have been looking for ways to increase their testosterone levels without using banned substances like growth hormone or steroids. The demand for testosterone boosters has lead to loads of research over the past 10 years into natural products that can help raise testosterone levels. Two products have emerged, Tribulus and ZMA.
For the past five years these two products have battled for supremacy in testosterone market. So let’s take a quick look at both products…
Tribulus Terrestris is a vine plant that grows in moderate and tropical climates in the United States, Mexico, Eastern Europe, India and China. Tribulus is extracted from the plant to make nutritional supplements.
Tribulus is used by bodybuilders and athletes to raise testosterone levels. Although the pharmacodynamics of Tribulus have not been established in human subjects, Tribulus is thought to support healthy hormone profile by boosting testosterone levels via stimulation of the anterior pituitary gland. This stimulation is thought to promote the production and secretion of Leutinizing Hormone, which can lead to increases in unbound, free-testosterone levels.
ZMA is a scientifically designed anabolic mineral formula. It contains Zinc Monomethionine Aspartate plus Magnesium Aspartate and vitamin B-6, and is an all-natural product that has been clinically proven to significantly increase anabolic hormone levels and muscle strength in trained athletes.
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.
So what works better, Tribulus or ZMA?
Firstly, let’s take a look at the research. Although Tribulus is oldest and most widely used of the two types of testosterone booster, it lacks in scientific proof that testosterone levels are raised. Some users report huge differences in mass and strength, and others report no changes when using the product. Also, the strength of Tribulus can vary depending on where the plant is harvested. Not all Tribulus Terrestris plants are created equal.
On the other hand, ZMA was scientifically developed specifically to increase testosterone levels. There have been dozens of studies into ZMA and the effects on weight trainers and strength athletes. On average, athletes had a 30% increase in strength when taking ZMA when compared to the placebo. The tests were performed on professional athletes, so the strength increases may be less on your average weight trainer.
When researching both Tribulus and ZMA we found that user feedback was generally more positive on ZMA than with Tribulus. Users reported good strength gains, and also said that ZMA helped them sleep better.
Costs wise, the products are generally similar in price, depending on brands.
The overall winner here is definitely ZMA. Scientifically developed, loads of solid research to back it up, good user reviews and well priced.
