It is manufactured by It Works, a US company headquartered in Palmetto, Florida. This multi-level marketing (MLM) company has its manufacturing units all across Europe and in Canada and New Zealand as well.

Calcium regulates the way the body stores fat and aids in their breakdown. It is believed that calcium in your body cells helps in the burning down of fat.

Better alternative Available?

Yes, PhenQ is a better weight loss product, but lets know why we are not recommending ThermoFight-X,

Keeping all the manufacturer’s claims aside, we put ThermoFight-X to real practical use. To be honest, it couldn’t manage to impress us. It doesn’t provide any long term weight loss solution. We understand the effects of these supplements vary from person to person. But the negative reviews came pouring in, which really made us doubt it even more. We also felt that 30 days are quite less to try out a supplement. Most of them kick in after that. 

The side effects are off the charts. One shouldn’t have to deal with so many of them just to lose a few pounds. Also, you will be charged for no reason, if you subscribe to their auto-shipping program unless you cancel it.

After reading the reviews online and even using it, we ought to tell you that It Works ThermoFight-X doesn’t really work. But we couldn’t leave you hanging, so we are suggesting an alternative. 

We recommend PhenQ that has proven its worth as a weight loss supplement. It is one of the best alternatives for ThermoFight-X. It is manufactured by Wolfsonberg Ltd, a leading producer of diet supplements. 

PhenQ uses a high-quality formula to help you lose weight. It has ingredients like a-Lacy and piperine that are beneficial in the process. The clinical trials recently confirmed that the addition of a-Lacy in the PhenQ formula helps in reducing body fat and weight. The study was done against Placebo where people using PhenQ lost 7% body fat, 3% weight, and gained 4% lean mass. you can also read the full review here

Here are ingredients used to create the formula of PhenQ:

a-Lacy Reset

It has been clinically tested to burn fat and lose weight by suppressing appetite. You can even expect to gain some lean muscle mass with this supplement. It also increases your energy and puts you in a better mood. 

Piperine helps in increasing the effects of the supplement. It is included in the Capsimax powder along with caffeine, capsicum, niacin, and vitamin B3. This powder increases your body’s temperature to burn calories through thermogenesis. 

Chromium Picolinate
