You can take Magna Rx as long as you don’t have high blood pressure. Lipozene is simply Glucomannan, which is a fiber that is supposed to make you feel full. There are no side effects to taking Glucomannan as long as you drink plenty of water with it because it expands. You should take the Lipozene alone, because it can affect the absorption of other supplements and medications. But you can take both supplements.
For future reference, the word “natural” is very vague. For instance, pig pee is “natural”. Companies have free use of the word. So always investigate a little further.

dunno it depends on what’s in them
