I wanna take a fat burner called trio slim and it contains 10mg BIOPERINE, can it be harmful or should I change my fat burner? Thanks in advance

Avoid "fat burners" Our bodies like to use glucose (our main fuel), which comes from the food in the stomach and small intestine, and from the liver (where glucose is stored in a starch form called glycogen). As long as one is not eating enough to supply glucose to his cells, his liver will run low on glucose/glycogen, and his body will burn other fuels like fat to keep his cells working. Eat less and exercise more.
