The weight loss product Calotren is a protein supplement manufactured and distributed by Top of the World Distributors. Calotren seems to claim to be a metabolic supplement that is suitable for both overweight users and users looking to improve their metabolic health. Interestingly, Calotren seems to come in both liquid and capsule form. A 30-day supply of the supplement retails from the manufacturer for approximately $65.00, making it a moderately expensive regimen to maintain. Instructions for Calotren use indicate that a full course of the supplement is intended to last 90 days, yielding weight loss and a more toned physique.

Both the liquid and capsule forms of Calotren are protein-based formulations. The product contains no ephedra or caffeine, both of which have been found to over-stimulate the metabolism and potentially cause rapid heart-rate and “jitters.” The official product website goes out of its way to point out that Calotren does not “stimulate, starve or trick” your body. While that does sound appealing, the further product claims are a bit ambiguous, implying that Calotren acts as a “support” for the body’s natural fat burning cycle, while also boosting stamina in non-overweight users. This ambiguity, both as to the product’s applications and its active ingredients, strikes us as a bit off. The mysterious Calotren protein also claims to benefit wrinkled skin.

List of Ingredients

The active ingredients of liquid Calotren are: Oxygenated water, Collagen Hydrolysate (Bovine Source), Aloe Vera, Glycerin, Potassium Sorbate, Natural Raspberry Flavoring, Methyl Paraben.

The active ingredients in capsule Calotren are: Collagen Hydrolysate (Bovine or Marine Source – your choice), Aloe Vera, Vegetable Glycerin.

Inactive ingredients in both forms of the product: Gelatin, Magnesium Stearate, Stearic Acid and Microcrystalline Cellulose.

Product Features

Calotren is intended to be taken once per day. Take either a single tablespoon or four pills of Calotren in the evening before going to sleep. For most effective results, do not eat anything three hours prior to taking the product and, if taking the pills, use only a glass of water to wash them down. This is so that your body can begin using the Calotren while you sleep. Top of the World Distributors also claim that taking Calotren in the morning or before exercising will give users increased energy.

  • Full ingredient list for product featured on official website.
  • Product is available from manufacturer online.
  • Product does not contain caffeine or ephedrine.


  • No free gift or multi-bottle purchase offered on official website.
  • Product claims are very broad, making it sound like an all-around “miracle” supplement. We’d prefer a product that focuses specifically on weight loss.
  • No product trials or development info offered on official website.
  • Reading the ingredient list, we see no proprietary ingredients that separate this product from others.
  • No free sample.


While we certainly appreciate that Calotren does not contain caffeine or other potentially harmful stimulants, we’re not really impressed by what it does contain. We are also weary of any product that claims to help with weight loss, boost energy and clear up wrinkles, all in one package. We’d love to believe in Calotren, but the official website offers no user testimonials or before-and-after photos. With so many proprietary products on the market for the same price, we’d hold out for something that can offer more sophisticated lab research and an approach that is specifically targeted towards weight loss.

    I am over 50 female and interested in this product due to Bob Cole radio testimony… However, my belly fat weight gain is largely due to hormonal non-production stage of life. Does this product work while going through this temporary transition?

    My husband and I both started Calotren right after Thanksgiving 2014…not yet reached 60 days. He has lost a little weight. I have not really seen any weight loss but have been able to move down from size 18-20 to my size 16 pants already. Can’t wait to see how things continue if things normally take at least 90 days for any real results as the instructions say. We have not changed anything at all about our routine or meals. Oh we are both 56 years old and remaining optimistic.

    I plan on ordering the product. I think results are different for everyone. At least this what I am seeing on reviews. I can tell you though as a certified herbalist, your body will not do what it is supposed to do if you are full of yeast or have untreated hypothyroidism. So to those of you whose reviews are negative you might want to check yourself for candida and have your hormone levels checked before trying any weight loss product.

    I started Calotren on 10/16/13, I have taken it nightly for 109 days. I started losing inches after about the second bottle I was on. I am now on bottle 4 and have lost one pant size and 10.2 lbs. I do believe you start to see the best results after your 90 days. I had been having trouble with both of my legs hurting at night after doing a complete split while mopping my closet in Auguest 2012…I would turn from side to side all night long with shooting, stabbing pin-like pain in both legs…I can honestly say the pain is now gone, and I sleep so much better now. I am on NO diet, and eat whatever I want…please give it at least 90 days to see results…it is awesome, and I will continue to take it!

    Never lost a pound, but after ripping my rotator cuff in my shoulder, it worked wonders at healing it. Also, as an older woman approaching menopause, it helped me to sleep through hot flashes better.

    I have taken this diligently for just over a year now. Exactly like I`m supposed to. Even did 3 rounds of Probiotics purchased thru same company as suggested. To date, I have not lost 1 single pound. Nor any inches. Nothing whatsoever. Very, very disappointing. I tried so seriously. Hoping.

    I was given 3 bottles of calotrin but i can’t find an expiration date on the bottles; where is it located and how old can the product be used safely?


  • 11

    Calotren works but it does take a while. You must be diligent in taking each night. It was not until the 13th week that I noticed my clothes were loose when usually tight and at that moment became a believer in the product and continue to use. Patience is definitely the key here. Thanks Calotren!

    Two months and haven’t lost a pound and have followed what they said, 4 pills with water at bedtime and no food 3 to 4 hours before.


  • 13

    I’m going to go out on a limb and say that Calotren – just like any other weight loss program – works differently on different people. I’m just sayin’ – I mean anyone with any sense knows that not everything works on everybody the same way. Thanks!

    I have been taking Calotren for over a year now. The first month of use I didn’t notice any change in weight loss, the second month, I dropped an entire pant size. I’m not a heavy person, size 10 and I dropped to a good size 8 (my clothes fit really good, not to tight and not to baggy). I had no change in my diet. Nor did I drink water with taking the pill and still had success.

    I’ve tried Calotren for a month and although I eat a healthy, low fat calorie diet averaging between 800 and 1000 calories a day, I haven’t lost any weight at all. I feel it was a waste of my money.



    unless you are a ” little person ” you should be eating at least 1200 caleries a day so your body doesn’t go into famine mode and store everything.

    Hi I want to know if there is no caffeine in this product why when I take it exactly as directed can I not sleep? I take it a 10pm right before going to bed and then I can not go to sleep until 3am I have tried everything to lose wieght and thought since Bama Brown from kase lost 100lbs it must be the best product for me. I tried to take this for 2 weeks with no weight loss and no sleep. hope you can tell me why this product wont allow me to sleep if ther is no caffine. thanks Debra

    My husband bought 6 bottles for my daughter and myself because Bob Cole at KVET had lost weight on it since I think December. But the thing you don’t hear in the ads is that (it tells you this in the book that comes with it) you’re supposed to give up starches while on it. Well, heck I know I can lose weight if I completely give that up. But they made it sound like you didn’t have to do anything special to lose weight while on this. BTW my daughter and I have not lost hardly anything yet.

    I have never slept better with this product! And it has aided me in losing 20 lbs in the last two months. Other than watching my fat intake and taking Lipozene, I am not actually dieting. I know three people personally that did nothing but take this product and still lost approx. 5-6 lbs per week.



    I sleep great when I take Calotren. I have more energy and therefore I am more active and that might be why I lose weight with it but either way I totally recommend anyone give it a try.

    I have had a stroke. Taking BP meds, meds for high cholesterol, meds for depression is it safe for me to take Calotren?



    I sure as heck hope not, as I am also on many meds due to a heart attack. The only problem I have seen so far is that, and I have been on it for over 60 days, it doesn’t seem to work. Not one pound or one inch have I lost. $200 down the drain.
