Calotren Review 2019 – Pros and Cons

CalotrenWhat is Calotren

All this buzz around Calotren made us curious about the supplement. Our review will cover some of the most important aspects including ingredients, benefits, potential side effects, pro’s & con’s, customer service quality, and scientific research. Furthermore, our review will also take into consideration what real consumers think about Calotren.

To start with, Calotren is advertised as an “advanced weight loss formula” for women and men alike. The supplement was developed by Top of the World Distributors, a U.S company located in Union City, TN. Top of the World Distributors was founded in 1997, and Calotren was released back in 2010.

Calotren consists of a collagen complex and prohydrolase, which according to the manufacturer, helps your body burn off sugars and fats more efficiently. The formula might also assist the body with protein absorption.

Calotren Ingredients

Calotren contains the following active ingredients: Collagen Complex 3000 mg and ProHydrolase 40 mg.

Other ingredients include Gelatin, Vegetable Magnesium Stearate, and Aloe Vera Leaf (200:1 Extract).

Benefits of Calotren

As stated above, Calotren is a very popular supplement for weight loss. However, we do have some concerns regarding this formula. First and foremost, is the complete lack of clinical support. Our research team couldn’t find any actual evidence to support Calotren’s formula regarding weight loss or fat burning.

Right, according to the official website, some nutritional experts helped the company develop this supplement, but saying that you are good at something and proving it are two separate things entirely. While the ingredients might help with protein absorption, there is no proof they will work to burn off fat, as claimed by the company.

Our concern is also fundamental on the many reviews and testimonials online, many people complaining about poor results even after several months of treatment. Here is an example of a testimonial available online: “I tried Calotren for a month and received no results. I worked out, cut back food intake and didn’t eat after 7 pm every night. I didn’t feel any different health wise either. I would not recommend this product.”


The second potential problem with Calotren it’s the actual formula. With obvious reference in the name, collagen is the core ingredient in Calotren. Many of you might have heard of collagen in various skin creams, as it is used to support skin health. But collagen is not limited to skin health; it can also be used to support overall health. In the case of this formula, collagen was used to burn fat and sugar, resulting in a noticeable drop in weight, or at least this is what the manufacturer claims.

But yet again, there is no clinical proof to support this assertion. Collagen is quite common and not very difficult to produce. If the substance is that effective at promoting weight loss, why there aren’t more collagen-based weight loss supplements out there?

As a plus, Calotren is free from caffeine and any ephedrine, stimulants or amphetamines. According to the manufacturer, the product is also side-effects free, but we will talk about that a bit later.

How Much Does Calotren Cost?

Calotren is available as capsules and as a liquid. According to the official website, a 90-day program is recommended for best results, which means you will need at least bottles of Calotren in order to feel any improvements.

Each bottle (120 capsules / 16 fl. oz.) is enough for up to 30 days of treatment, and it costs $69.95. Buying three bottles at once (for the recommended 90-day program) is a bit cheaper, and it will cost you about $190.

Potential Calotren Side Effects

Calotren is free from any stimulants, but that doesn’t mean the supplement is free of any side effects. Collagen is important for proper health, but an excess of it is not recommended. The use of collagen has been linked to potential fatigue, abnormal heart rhythms, and bone pain.

Aloe vera is known to cause allergic skin reactions, dehydration, and constipation.


  • Calotren does not contain caffeine or ephedrine
  • Can be purchased online from various retailers
  • The supplement is quite popular


  • A broad range of claims associated with this supplement. Doesn’t seems to be focused on something in particular
  • The formula is not very complex, there isn’t much information regarding the ingredients
  • No clinical evidence to support the claims behind the product
  • Very expensive

Final Verdict

We do appreciate that Calotren is caffeine and stimulants free. We’ve seen many similar supplements “bombarding” the user with high doses of caffeine and other stimulants, resulting in a short energy boost, followed by an abrupt drop in energy levels.

Sadly, Calotren is one of the products that claim to support weight loss, clear up wrinkles, boost energy, support proper joint and bone health, and the list can go on and on. We fear it’s just one of those all in one package supplements that are “good for everyone” regardless of their expectations.

With so many proprietary products on the market, at more reasonable prices, we’d hold out for something that can provide more extensive clinical research and an approach that is more focused toward just one health concern.
