How Does It Work? | The Science Behind Calotren

Calotren claims to help reduce weight by inducing the body to shed off excess fats. At the same time, it claims to help gain muscle mass[2], giving its user the proper balanced weight. The product also claims to reduce your appetite and lowers your total calorie intake.

Lastly, it can also enhance your energy levels for improved physical performance, and even strengthen your joints with some of its additional ingredients.

Calotren Ingredients – The Breakdown

Calotren has been very effective in inducing weight loss, all thanks to these five key ingredients:

Magnesium Stearate – This compound is a popular ingredient in most pharmaceutical capsules, powders, and dietary supplements. The exact mechanism is still unknown, but studies report a strong correlation between magnesium levels and weight loss.

This 2013 study[3] from PLOS ONE proposes the weight loss effect being a result of decreased insulin resistance.

Aloe Vera – This medicinal plant is said to have laxative properties that help improve gut health. A healthy digestive tract translates to a faster metabolism rate. The metabolic effects of aloe vera is one of the topics in this chapter of a book entitled Herbal Medicine: Biomolecular and Clinical Aspects (2nd edition)[4].

Vegetable Glycerin – This clear liquid extracted from palm oils, coconut, or soybean aids in weight loss by improving exercise performance.

Microcrystalline Cellulose – This substance induces weight loss by curbing the appetite, which does so by triggering parts of the brain to make the stomach feel full.

Gelatin – Derived from collagen, gelatin is a colorless and flavorless ingredient used in many different foods. It helps reduce appetite.

    By Travis M. 

    Product does not work. It has zero effect. It is worth nothing. Not recommended.

    This was a total let down. I read reviews and it did not live up to them. The product does not work. It has zero effect.
