Cellucor CLK Ingredients

ingredients

The Cellucor CLK formula markets itself as a simplified composition containing only the very best essential ingredients.

Conjugated Linoleic Acid (CLA)

An omega fatty acid believed to play a role in promoting lean muscle tissue growth while reducing stored fat cells by using them as a source of energy2 .

L-Carnitine Tartrate

Also known as propionyl-L-carnitine or L-carnitine, this amino acid is stored in the human body, especially in the muscles.

It promotes the oxidation of fatty acids, producing energy and reducing the formation of free radicals.

It functions much like an antioxidant and may contribute to faster recovery after working out3 .

Raspberry Ketones

A natural phenolic compound that may promote fat metabolism.

Raspberry Ketones are known to increase lipolysis (the breakdown of fat), by increasing cell sensitivity to the effects of norepinephrine, the fat burning hormone.

It also promotes the release of adiponectin which is believed to play a role in regulating blood sugar levels4 .

Fish Protein Hydrolysates

This ingredient, derived from Blue Whiting fish, provides amino acids that protect lean muscle tissue.

There is evidence that these FPHs improve body composition, repair muscles and tissue, and help control appetite5.

They may also play a role in blood glucose control.

Katrina Rasmussen writes:

I lost about 30lbs taking these pills. I do diet but I don’t exercise. It took about 3 months. I plan on taking them for another 3 months in order to reach my goal. I eat three meals a day but don’t really snack.

Just try to eat healthy and I’m sure if you exercised you would get better results than me but I just physically can’t exercise so I’m just strict with my diet. Good luck!

Amazon customer writes:

DISCLAIMER: My first time every purchasing/ using a pre work out.

I have taken this product a few times but every time it makes me feel super tingly all over and on the rare occasion gives me the runs! When it doesnt give me the runs it does really give me the energy i need to power through my work outs after a long day of work!

Im not sure I would buy this again because I do want to try other products out there! The taste is great doesnt taste like chemicals or anything and mixes easy in water

Meggy56 writes:

These have always been my go to for workouts! Nothing compares to Cellucor out of everything I’ve tried. I don’t feel overly jittery like other brands that make me feel like I’m just loaded with caffeine and end up making me lightheaded. These give you all the focus and motivation you need!

Cardio is my least favorite but I zip thru it like nothing and have a noticeable difference in distance and time compared to when I don’t take them. Another bonus is I don’t feel as sore the next day even with weight training.

Alex G. says:

There are definitely better products out there to stimulate weight loss. Did not notice an increase of energy or focus to any extent, if at all. Nothing bad to say about this product, but no significant change in my weight even with a diet proved to me that this supplement was not as effective as it claims to be. Would reccomend looking elsewhere 6/10.

John X says:

I took this while simultaneously doing P90X and body beast and using my fitness pal to only eat a diet of 1500 cal a day. Given that intense fat loss routine — I assumed that this product would help me lose weight – instead I lost 0 pounds while using it. I found that it made me nauseous, increased my appetite, and gave me digestive problems – and also made me feel lethargic. It’s a complete gimmick. It’s going to be off the market within a year.

On top of that wrong doing – the product is prohibitively expensive and if you take the recommended dosage — it only last 10 days! This is capitalism and diet fad marketing at its absolute worst – don’t waste your time. It’s absolutely criminal that this is allowed to be sold to the public. Isn’t there anyone regulating diet supplements? Special raspberry ingredients? Incredulous nonsense.
