Cellucor CLK is a new weight loss supplement from Cellucor. The supplement is not the company’s first attempt at formulating a dietary aid that boosts weight loss and this try is not exactly a stellar attempt. Aside from Raspberry Ketones, the formula provides not proven weight loss benefits for the average dieter, but it does taste like raspberries.

List of Ingredients


  • Conjugated Linoleic Acid
  • L-Carnitine
  • Raspberry Ketones
  • 7-Keto DHEA

Product Features

There are only four ingredients listed for Cellucor CLK. The first is conjugated linoleic acid, commonly referred to as CLA. CLA was an extremely popular weight loss ingredient about 10 years ago, but soon science reported no real weight loss benefits for the average dieter. That didn’t seem to stop companies from adding CLA to supplements and smacking a weight loss claim in the product description. According to studies, CLA may boost lean muscle mass for athletic users and concurrently reduce body fat, but the same cannot be said for average dieters. CLA has been associated with stomach discomfort and gastrointestinal side effects.

Raspberry ketones are the new hot ingredient thanks to Dr. Mehmet Oz supporting the supplement. According to the website for Dr. Oz, raspberry ketones have some support via in-vitro and animal studies, but at no point have human studies been completed on the extract. We searched PubMed and found no indication of any human clinical studies.

Rounding out Cellucor CLK is 7-Keto DHEA. According to WebMD, there is no evidence supporting weight loss when taking 7-Keto DHEA. We were unable to find any clinical studies supporting weight loss claims associated with 7-Keto DHEA.

  • All ingredients for Cellucor CLK are listed online.
  • The product is available for sale online.
  • The softgels are raspberry flavored.


  • Contains no proven weight loss ingredients.
  • May cause stomach discomfort.
  • May be playing off raspberry ketone popularity.


If at least one of the ingredients in Cellucor CLK was proven to spark weight loss or boost thermogenesis we could throw Cellucor a bone on CLK, but we found no evidence any of the ingredients in this formula are worth the $70 you’re paying for just one bottle. The flavoring is a nice touch, but it won’t make Cellucor CLK a better supplement. With additional research, raspberry ketones may be proven to support weight loss in humans, but a raspberry ketone supplement is far less expensive than Cellucor CLK.
