Too strong for me

Posted by 5541813592955290667 on Jan 17, 2017

This product was unfortunately too strong for me. I tried taking half a capsule at night and I did sleep better but felt extremely groggy all day the next day. It might be because I have MTHFR and that messed with my methylation.

Mild effect so far in 2 weeks

Posted by 4729228397306168751 on Jan 16, 2017

I purchased this product to help with my migraines and suppress my sweet cravings. As for migraines, effect is mild with using 3 times a day, still have to take migraine medications(about the same amount). With cravings it does a little better, reducing it to about in half, which makes me happy :) I'm only using this product for a couple weeks, so see what happens in a longer run.

Not sure about effects

Posted by 4993781291824174970 on Dec 03, 2016

I want to believe that this is effective, but not sure. It bothers me also that it is recommended taking it on an empty stomach.
