Instant Knockout vs PhenQ vs Leanbean: Comparing Side Effects

Instant Knockout

Being a potent performance booster fat burner supplement, there are some possible side effects that you may experience with Instant Knockout. These side effects include rapid heart rate, anxiety, insomnia, increased blood pressure, fatigue, a few digestive issues, and addiction.


PhenQ is one of the safest fat burners on the market, and it is claimed to be 100% free from any possible side effects. But being a dietary supplement, the chances of side effects cannot be ignored. Possible side effects of PhenQ are bloating, nausea, headaches, stomach aches, and dizziness.


The official website claims that Leanbean uses natural ingredients and therefore does not carry any side effects. But if you are allergic to caffeine, then you may experience jitteriness. But this is not serious to me; rather, there is something else that worries me. It uses a few testosterone-boosting ingredients that may not be safe for women as it may restrict the production of estrogen.

Instant Knockout vs PhenQ vs Leanbean – Which Is The Best?

buy phenq

All three fat burner supplements are specific to their claims and have their own formulation and benefits. It would be an injustice to choose a winner while degrading the other two. If you ask my consideration, I would say that if you are specific with your choice then it is quite easy to pick your fat burner.

Elaborating my consideration, if you are someone looking to burn fat and build muscle mass, then Instant Knockout is best for you. Or if you are a lady, looking for a specifically formulated supplement for females then you can surely go on with Leanbean. But making my choice, I pick PhenQ as a universal fat burner as it is a versatile player.

It works equally for both men and women, helps in burning fat and losing weight along with building muscle mass, and in bonus, it also helps improving mental cognition and mood. At last, be wise while making your choice. You can also read our complete list of PhenQ alternatives for more options.
