Grenade Review

Our Rating

Weight management can be a nightmare when you are trying hard to get the perfect physique and that is why fat burners are so popular.

However if you want to win your war with fat then Grenade could just be the best weapon in your arsenal.

A marketeers dream, Grenade claims to have the “most potent dosages of the most important weight loss support ingredients” and there is definitely some good stuff packed into the capsules.

However it also includes bitter orange – which contains the chemical synephrine – and there are cautions over the possible side effects attached to it.

Ingredients and how they work

Grenade Thermo Detonator Proprietary Blend (Green Tea Extract, Bitter Orange Extract, Caffeine Anhydrous, Grapefruit Seed Extract, Capsicum Annuum, Evodiamine, Yohimbe Bark Extract, Raspberry Ketone, Phenylalanine, Cocoa Bean Extract, -phenylethylamine HCl, Coleus Forskohlii, Yerba Mate Leaf, DMAE)

Green tea contains catechins which increase the thermogenic process and inhibit the fatty acid synthase enzyme, while caffeine stimulates the metabolism and increases energy.

Caffeine is also a key content of Yerba Mate, which also includes bioactive compounds like chlorogenic acid and ursolic acid.

Bitter orange can boost the thermic effect of food, although it may also increase heart rate and blood pressure.

Capsicum gives the body a thermogenic boost, while coleus forskohlii helps to reduce fat mass and levels of fatigue.

There are some side effects linked to yohimbe, although it has been proved to be an effective ingredient in the fat-burning process. Beta-phenylethylamine helps boost dopamine.

However research into cocoa bean and raspberry ketone in terms of weight loss is limited.

Grenade Thermo Detonator review conclusions

Fancy packaging aside, Grenade also has some plus points going for it in the ingredients, such as green tea, caffeine, coleus forskohlii and capsicum.

However the inclusion of bitter orange could well put people off, while there are side effects linked to yohimbe as well. Also the fact Grenade opts for a proprietary blend means it is unclear how of each ingredient you are getting.

Grenade has picked up a number of awards in Europe and the UK (although the ingredients list is slightly different), while it has generally received good reviews.
