Package Tampering
On 7/12/18 I purchased this item at the Sutton Plaza Store in Flanders NJ. When I got home and was opening the bottle I observed that the plastic seal around the cover was intact, but the second seal normally glued to the top of the bottle had been removed and was just sitting on top of the rim. There was also very little cotton in the bottle. Upon examining the contents there were 93 tablets in the bottle, not 60 as there were supposed to be. I immediately took the bottle back to the store where a very nice sales associate assisted me. We opened a new bottle from the store shelf. Both safety seals were intact and there were 60 tablets in the bottle as there were supposed to be. The tablets however were significantly larger than in the first bottle which contained 93 tablets. The associate exchanged my original purchase, apologized profusely and said he would notify the manager. This is a serious problem, everyone should inspect all safety seals very carefully. I have yet to hear back from management regarding how this could have happened and what they will be doing to prevent this in the future.

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.

A shopper on Mar 23, 2016
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.
what is the difference between this product and L-Carnitine 500? For weight loss, which one works well? I do not want get too many musles. Musles may make me look strong not slim.
A shopper on May 19, 2013
BEST ANSWER: L-carnitine 500 contains 500 mg of L-Carnitine per tablet while L-carnitine 100 contains 1000 mg of L-carnitine per tablet. L-Carnitine is not a bulking agent and will not make your muscles grow. It fuels metabolism, protects lean muscle and supports exercise recovery.
