Other weight loss pills contain caffeine, but green tea is the only natural substance that can give you the energy you need to burn that extra fat. But since caffeine is linked to heart problems, there are some risks involved. So, these pills will be best if you can stop taking them after a certain period of time. If you cannot, then you must consult your doctor about it.
The good thing about green tea capsules is that there are many of them available in the market. But remember that these capsules should not be taken every day, but only during the day. The safest way to take it is to take them when you feel like taking it, and then stop at once.
