Despite claiming that BSN’s Thermogenic has the most advanced thermogenic weight loss formula to hit the supplement market over the years, this formula is not specifically revolutionary. Most of the ingredients are pretty common. That is not to say that this is not a powerful product that will deliver some results. But those who are sensitive to caffeine may want to avoid this product or at least start your dosing with one pill twice daily to assess your tolerance, as there is around 300mg of caffeine included in each serving of this Thermonex.

Now let us check the ingredient label of Thermonex and know what is in it.

1. Caffeine: There is a ton of caffeine in Thermonex. Caffeine’s fat burning abilities are well documented and it is an obvious addition to any fat burner. When caffeine is combined with green (which is also included in Thermonex), the effects of caffeine can become even more overbearing.

2. Green Tea: There is 375 mg of green tea included in the Thermonex formulation. Green tea is among the fat burning ingredients that show real potential for weight loss. This is certainly a nice addition to the formula.

3. Octopamine – This is a trace amine with no real conclusive evidence that exists for weight loss benefits. Furthermore, octopamine has a very low oral bioavailability and is broken down by the enzyme monoamine oxidase. Therefore, it is the small amount included in the formula that has a good effect.

4. Advantra Z®: This is a proprietary citrus aurantium extract that is regulated for synephrine, which is an ingredient called the chemical cousin of ephedrine. You will find numerous weight loss products as well as websites showing all the wonderful weight loss benefits of synephrine. Unfortunately, clinical data validating these claims is scarce.

5. Evodia Rutaecarpa – This is a Chinese fruit that has the ability to help with weight loss by increasing the body’s heat production as well as decreasing the body’s ability to store fat. The only problem is that those claims have not been scientifically confirmed in humans. There are some studies done on rodents as well as promising “in vitro” studies, but the jury is out on whether this product will show a good weight loss effect for humans.

6. Naringin – This is a grapefruit extract that serves as a good source of fiber and is supposed to reduce the actions of cytochrome P450, which is associated with obesity. This also enhances or extends the effectiveness of the other ingredients.

7. Yerba Mate: This is a source of caffeine and some other xanthines. This can reduce the activity of the monoamine oxidase enzyme, which increases the bioavailability of the octopamine in this formula. In addition, Thermonex also contains iodothyrosone, diiodotyrosine and l-tyrosine, all thyroid hormone precursors.

The real weight loss benefits of BSN Thermonex lie in its green tea and caffeine content. Although some other ingredients in the formula show some potential, their benefits are not conclusively proven.
