Ingredients in Calotren

Calotren is a weight loss supplement that advertises as a no side effect, all natural, stimulant-free way to lose weight. It does not have caffeine or stimulants such as ephedrine to fuel metabolism, but instead has a more natural formula. Calotren is offered in both liquid and capsules and both have slightly different ingredients.

The capsule form of Calotren has collagen hydrolysate, aloe vera and vegetable glycerin as its active ingredients. Hydrolyzed collagen was created in the 1970s and is a common additive in weight loss supplements. While it doesn’t burn fat, it boosts the body’s metabolism to a state where burning fat can occur. Aloe, according to, is an antioxidant, antibacterial and anti-inflammatory. Glycerin is a natural fat that is used to absorb liquid.

Active Ingredients Calotren Liquid

Calotren in liquid form have the active ingredients of collagen hydrolysate, aloe vera, glycerin, potassium sorbate, methylparaben and natural raspberry flavoring. This has the same ingredients for the same reasons as the capsules, along with flavoring to make it easier to swallow and the preservatives methylparaben and potassium sorbate to keep it from spoiling quickly.

Inactive Ingredients in Liquid and Capsules

Both the liquid and the capsule form of Calotren have the same inactive ingredients. These are gelatin, magnesium stearate, stearic acid and microcrystalline cellulose. Gelatin, stearic acid and magnesium stearate are all three thickening agents used to make the compound able to stay together. Gelatin is from plants or animals while stearic acid is a fatty acid. Microcrystalline cellulose is found in plant cell walls and is categorized by the FDA as safe for a food additive. It is used as an anti-caking agent and a bulking agent to keep the product intact.
