Review Overview – What does Cellucor CLK do?

cellucor-clk-reviewBrought to us by Cellucor, CLK is a stimulant-free fat burner claimed to:

  • Raise Energy
  • Tone and Sculpt
  • Burn Fat

But does it work?

We’ve done the research and looked closely into the science of CLK and we were sorely disappointed with the results.

If you’re interested in buying this product you NEED to read this review. Here’s what we found:

How are the servings in CLK?

Not great.

With only 2 servings a day, there’s only so much you can get out of CLK at a time. These are not enough to keep your body in a constant ‘fat burning’ state.

What you should be looking for

For the best results, the top fat burners on the market have around 3 – 4 servings per day. This gives your body the constant supply of nutrients it needs to keep effectively burn fat.

What about the ingredients?


There’s a serious problem with Cellucor CLK and that is that it contains no legitimate thermogenics.

By avoiding the use of stimulants the CLK, this supplement has looked to poorer alternative to help with fat loss and it hasn’t paid off.

There’s only one good ingredient in here worth considering – and it’s part of a proprietary blend. This means we don’t know how much of each ingredient is actually being used – or how effective it will be, take a look:clk-ingredients

Honestly? CLA is massively over-hyped…

Unfortunately this is a common fat burning ingredient used in stimulant-free fat burners – and it’s not an effective one.

Though to induce fat loss by working on the PPAR receptors in the body, unfortunately Conjugated Linoleic Acid isn’t strong enough to have an effective impact and promote fat loss. There has yet to be a study to argue a case for it being effective.

L-Carnitine is a good move for energy…

L-Carnitine is always a good choice. A solid metabolism booster, this amino acid raises energy levels and keeps your body going when you’re on a low calorie diet.

However, you need at least 500mg for effective results, and as this is part of a proprietary blend, we have no idea how much is actually being used, or if that amount is in there.

Raspberry Ketones however, are pretty damn useless…

Raspberry Ketones have been marketed very well for a nutrient that actually does nothing. Originally brought to light by TV’s Dr Oz, this useless fat burning nutrient has only ever been seen to work in high doses on rats.

The results don’t scale up to humans – you will get no fat burning benefit from Raspberry Ketones.

And the Blue Whiting is literally just fish…

You may get some omega-3 and general joint care vitamins out of this, but there’s really not much benefit to it.


Ingredients Bottom Line

Overall this is a dud fat burner. The main fat burning ingredients have never been seen to burn fat!

A lot has been missed out from Cellucor CLK, and there was many other good nutrients they could’ve chosen to make it more effective without stimulative effects; green tea catechins, green coffee bean and cayenne pepper all would’ve been suitable.

On top of this we don’t even know the value of the only effective ingredient in here that would make any difference.

It’s a shame. And a waste of money.

Side Effects

Unless you have an allergy to seafood, you shouldn’t have a problem with side effects.

Cellucor CLK Review Conclusion

Overall CLK is an awful supplement.

It has failed for both ingredients and servings. Here are the main errors that have been made:

  • Poor Servings – Only 2 a day, not enough for round the clock fat burning
  • Ineffective ingredients – No studies back up the evidence that CLK actually helps burn fat, in fact some suggest its too weak
  • Proprietary blend – We don’t know how much of each ingredient we’re getting or how effective it will be
  • Missing core ingredients – No thermogenics in this blend to promote fat loss

We definitely don’t recommend this product, however, if you’re looking for fast and effective fat loss, we strongly suggest you check out one of highest rated fat burners in the link below:
