Overview

Coleus forskohlii is an herb from the mint family, traditionally used in Ayurvedic medicine. Its primary active compound, Forskolin, is believed to aid in weight loss by increasing levels of a molecule called cyclic AMP (cAMP), which may stimulate fat burning.

Key Benefits

May Aid in Weight Management

Forskolin increases cAMP levels, which can lead to an increase in fat breakdown (lipolysis) and may help reduce body fat.

Improves Body Composition

Some studies suggest that Coleus extract can help increase lean body mass while decreasing fat mass, leading to a more favorable body composition.

Supports Cardiovascular Health

Forskolin has been studied for its potential to lower blood pressure and improve heart function, though more research is needed.

Dosage & How to Take

The effective dose of Coleus extract depends on the standardization of Forskolin. Most studies use 250 mg of an extract standardized to 10% Forskolin, taken twice daily.
