Optimal results with CLA
I have seen the reviews below, but what I will say is that if you combine this with a CLA + the RIGHT exercise program you WILl lose weight. Try a protein shake during the day too to optimize the weight loss. Taking this product just by itself wont really do anything for you.

No noticeable difference
I’m still on the fence about this product. I have been taking it twice daily for 2 weeks now. I have lost a pound & a half but I have been exercising everyday & eating nothing but Jenny Craig meals. I honestly haven’t noticed any difference in the way I feel. I had high hopes because my physician swore by this product.

can you take this product and cla complex at the same time?
A shopper on Mar 8, 2013
BEST ANSWER: Yes you can. For optimum fat burning you should stack the following or find a good burner that incorporates the following.

Yohimbe = Fat releaser
Capcaicin = calorie burner
Carnitine = fat transporter (all the freed up fat has to be escorted to mitochondria to be burned as
CLA = Fat Blocker

Take all four or an equivalent with your pre-workout meal. Carnitine again with the meal post-workout and a final time with your last meal of the day. The other three another 2-3 times throughout the day. Careful not to take some before bed as it may make it tough to fall asleep.
