What You Need To Know About Cellucor CLK

Cellucor CLK is a supplement claiming to help sculp and tone the body by boosting the metabolism and supressing appetite. It is a blend of conjugated linoleic acid (CLA), L-carnitine, raspberry ketones and SlimPro – a protein extracted from fish. Users have to take six capsules a day, which we think is a lot especially with a bottle containing only 60 or 90 capsules. The ingredients list feature several component that have never been clinically-tested and while they are deemed safe, there is no evidence of their effectiveness.

What Are The Side Effects Of Cellucor CLK?

Cellucor can cause several side effects such as jitteriness, weakness, restlessness, insomnia, chest pain, headache, nausea, rashes, stomach upset, diarrhoea, fatigue, vomiting, heartburn, arrhythmia and respiratory trouble. It can also cause urine, breath and sweat to have a ‘fishy’ smell.

How Much Does Cellucor CLK Cost?

Cellucor CLK is quite expensive. It is sold in bottles of 60 or 90 capsules that lasts only 10 or 15 days; the small bottle is $49.99 and the larger bottle $69.99.

Our Verdict On Cellucor CLK

We do not think that Cellulor CLK is worth the price. When taking six capsules a day as recommended, a bottle will only last 10 or 15 days. Furthermore, some of the ingredients contained in Cellucor CLK are understudied and have an extensive list of potential side effects. Because of this, we cannot approve of Cellucor CLK.

Does Cellucor CLK Work?

Even if many reviews are positive, we do not think that Cellulor CLK will lead to a significant weight loss. CLA does appear to have some slight effect on the body by reducing fat mass and helping muscle growth, but there is no solid evidence of its effectiveness. Plus, it is deemed unreliable and unpredictable. Raspberry ketones have been tested on rats only, never on humans, so it is impossible to say that it will work.

What Are The Ingredients of Cellucor CLK?

The ingredients used in Cellucor CLK are provided below. The ingredient quantities provided are per serving of three capsules. Each serving of three capsules contains 25 calories.

  • CLA Conjugated Linoleic Acid (CLA): Naturally found in dairy products, beef and safflower oil, CLA may help to reduce body fat. Human studies on CLA have produced contradictory results and it is described as not only a relatively poor fat burner, but also an unreliable one.

Stimulant Free Toning Blend

  • L-Carnitine Tartrate: One study found that supplementation of L-carnitine can help reduce muscle tissue damage from exercise and speed up recovery time.

  • Razberi-K Raspberry Ketones: The raspberry ketones used in this supplement is lab-synthesised. Whilst there is some evidence that raspberry ketone can cause weight loss in rats it has never been clinically tested on humans.

  • SlimPro (protein hydrolysates of blue whiting): Called a ‘natural marine ingredient’, this fish extract is described as follows on the official website:

    Taken daily before meals, Slimpro® increases the production of CCK and GLP-1 in the body, thus amplifying messages associated with a decrease of food intake. Promising results were reported from in vivo et in vitro trials of these molecules that may control food intake.

Are There Any Customer Reviews For Cellucor CLK?

There are numerous customer reviews for this product on the various websites that sell the product. Here are a few examples:

I bought this from GNC. I stack it with HD capsule. You take three of these in the morning and one HD in the morning. It does not specify on empty stomach or not. I take it twice/day, on a empty stomach then I eat 20 or 30 min later and drink plenty of water.The first day i took it, I had so much energy, I couldn’t be still, my hands were a little shaky cause I was moving around a lot. I felt like a kid that had nothing but sugar all day. It works I started sweating, heart was beating fast. I haven’t went to the gym yet I will be going later on today to see how it is. I also take Cellucor BCAA while working out as well. I train everyday, I’m a Veteran so I’m used to working out. I do my 30 min of cardio then weight lift and circuit train. I will see how this works for me today during my workout.

Worked excellent for my training of taekwondo + running + bodybuilding to have more energy and more power. I can train 2 times better with this than normal and also can do more!! I have a breathing problems and this help me to breath better!

I did notice that my stomach was flatter and my appetite was curbed pretty well while on this. However, it gives me the same results as any CLA formula I’ve taken, and those are much cheaper. I just got a 3 month supply of CLA for half as much as a one month supply as this. Does it work great? Absolutely. Worth the extra money? Not so much.

This is the first non-stimulant weight loss product I have tried. It was expensive and I’m not sure that it was worth it. The first two weeks taking 1 capsule 3 times a day seemed to help immensely with weight loss but after that it seemed to quit working. I’ve been on a strict diet and working out regularly.

This was my third and final try at the product. The first two times I never did a full cycle and I didn’t really watch my food…so I couldn’t give an honest review. This time I cleaned up my diet and religiously took this…Practically no results. My boyfriend has amazing results on it, so it works for some…just not for me.

I recently just went through a contest prep resulting in third place in an Australian national teen devision of the IFBB. I am a big fan of Cellucor products and during my prep i was looking for a little extra edge in aiding my fat loss. The 4 weeks i used the CLK my body fat percentage dropped from 18% down to 13%, of course with strict diet and exercise. But never the less the CLK definitely helped speed up the process. Will be a handy thing in my next prep. Great product.
