    Really helps you to burn fat...

    Posted by acumen on Aug 19, 2013

    ... while exercising. I take 4 of these just before an exercise, and it makes you sweat like a pig. I've really noticed the difference on my body and have lost weight and excess fat quite rapidly. PS. Be sure to check my profile page for +180 reviews on iHerb products.

    Best Cartine Product EVER !!

    Posted by Sickness-ELIMINATOR on Aug 11, 2013

    Mitrochondrical energy optimizer! This stuff uses your fat to make energy inside the muscle cells, as I understand it. It's a nice, even energy, so mellow that you only notice it when you don't run out of energy around 4:00 p.m., or take it so late in the afternoon that you wonder why you're still staring at the ceiling instead of sleeping at night. Don't expect to see any weight loss. but you will have more energy and no jitters.

    Good for weight loss and for the liver!

    Posted by Reviewer1058120 on Jul 19, 2013

    Good carnitine, took a capsule on an empty stomach 3 times a day, well interrupts appetite. If you do the fasting days, then it will be easier for him. Taking it on an empty stomach in the morning and in the afternoon, I caught myself thinking that for dinner I ate almost nothing, and I felt fine. A month lost weight (without doing sports) at 3.5 kg. Also good for the liverGood Хороший карнитин, брала капсулу на тощак з раза в день, отлично перебивает аппетит. Если вы делаете разгрузочные дни, то с ним это будет легче. Принимая его утром на тощак и в обед, я ловила себя на мысли, что к обеду я ничего почти не ела, и чувствовала себя отлично. За месяц похудела (не занимаясь спортом) на 3.5 кг. Так же хорошо для печени.

    I take this supplement every morning. This, coupled with good eating and exercise, seems to help me drop weight easier than without it! I love it!
