What is forskolin:

Forskolin is extracted from the root of the Indian coleus plant. Indian coleus plant belongs to the mint family. It is indigenous to India, Nepal and Thailand. This herbal extract has long been used in the field of medicine for its beneficial effects. Its uses are especially diverse in Ayurvedic Medicine.


Chemically, Forskolin, is a labdane diterpene. It is also known as coleonol. Forskolin contains some unique functional groups, the most important of which is a tetrahydropyran-derived heterocyclic ring.

The basic mechanism of action:

Forskolin acts at the cellular level. It activates an enzyme in the body called adenylyl cyclase. Activation of this enzyme increases the amount of cyclic AMP (cAMP) inside the cells. Think of cAMP as a postman. It takes messages from the cell membranes to the nuclei. For example, when a hormone binds to the surface of a cell, it activates adenylyl cyclase, producing cAMP which takes the message inside the cell to the nucleus, thus eliciting the required response.

This makes cAMP important in eliciting the effects of different hormones in the body. It plays an important role in the release and action of different hormones from the hypothalamus, pituitary and thyroid glands.

This effect of Forskolin is utilised in various scientific experiments. But besides its uses in the laboratory, it has many practical uses as well.

Uses of Forskolin:

Traditionally, Forskolin has had diverse medical uses, especially in Ayurvedic medicine.

  1. Asthma: It is a popular folk remedy for Asthma. Forskolin relaxes the bronchial smooth muscles thus alleviating the symptoms of Asthma; like wheezing and breathing distress.
  2. Glaucoma: It decreases the pressure in eyes seen in Glaucoma. Its concomitant beneficial effects on both asthma and glaucoma, makes it an effective remedy for glaucoma patients who cannot tolerate beta blockers because they are asthmatics as well.
  3. Cardiomyopathy: It was used historically in the patients of cardiomyopathy. Some trials suggest that it does improve the ejection fraction of the heart, improving its function.
  4. Urinary tract infections (UTIs): It is especially useful in the prevention of recurrent urinary tract infections. Forskolin prevents their recurrence so that the excessive intake of antibiotics can be avoided.

Each use listed above has been subjected to at least some amount of trials and studies, if not a lot.

But the most important and relevant use of forskolin in this modern day and age is its use as a weight loss tool.

Forskolin and its use in weight loss:

One use of Forskolin, and the most important one in this modern day and age, as an effective weight loss agent, has especially emerged forward in the past few years. With 30 percent of the world’s population being overweight, this is a breakthrough scientific finding. Studies and trials have been done, where it is evident that forskolin is an effective tool for weight loss.

How does Forskolin help weight loss?

1. Forskolin increases the metabolic rate of the body.

You must have observed that the same amount of food intake has different effects on different people. Some people stay lean while others get obese while taking the same amount of food and calories. Why is this so? This happens because of the different metabolic rates of different people.  Some people have a naturally fast metabolism. They can eat anything without putting on weight. Some people have a slow metabolism, they put on weight even if they don’t consume that many calories.

That’s where Forskolin comes in, it increases the metabolic rate of the body, inducing weight loss. Forskolin increases metabolic rate by increasing the action of hormones in the body (eg thyroxine)

2. The body metabolism also slows down with age. Younger people have a relatively faster metabolic rate. So forskolin also helps those people lose weight, who have become obese with the increasing age.

3. Another important benefit of Forskolin is that it reduces the body fat while preserving the amount of muscle in the body. Because body uses its fat stores to obtain energy and not the muscle mass, and forskolin is just accelerating this natural process, so body fat is lost but muscles are preserved. Muscles are the workhorses of the body, fat is an unwanted guest. Using forskolin, you will lose weight but you won’t lose any strength or energy.

4. Forskolin can also help gain some muscle mass in very lean people. This advantage is attributed to the fact that it increases the testosterone levels in the body. Testosterone is an anabolic hormone that causes the build-up of muscles. This was also proved in a blind trial that forskolin increases the muscle mass of the body.

So in summary, forskolin:

  1. Causes weight loss.
  2. Increases the metabolic rate of the body.
  3. Helps the body to burn the fat faster.
  4. Preserves the muscle mass of the body.
  5. It can also help to gain some muscle mass in lean people.
