Definitely Helps

Posted by 5607987390740835114 on Jan 03, 2016

I had "mild" depression I guess, and it helped me feel much better. The only side effect I was getting was a heartburn after taking it, it's not bad now, I try to take it with food - I read its better to take it with just carbs (like a banana or something). This has "veggie" capsules, so it's good if you're looking for Halal or Kosher. I'd recommend this product.

Reduces sugar cravings

Posted by Reviewer2917570 on Dec 12, 2015

I take this to reduce my terrible cravings to sugar and sweet foods. It works! I take 2 capsules at nighttime, after about 2-3 weeks my sugar cravings have mostly disappeared. It helped to elevate my mood a bit too, and reduce anxiety. If you have uncontrollable sugar cravings, give this a try!
