Does CalmLean Work? Evidence on This Caffeine-Free Fat Burner

The Meaning of Caffeine-Free Here

The maker says CalmLean has no caffeine or synephrine, the stimulants that power many fat burners. Cayenne pepper extract, a mild thermogenic, is in the formula. Without caffeine you avoid jitters and sleep problems, yet the product still isn't right for everybody. Forskolin can raise heart rate and lower blood pressure, which means a doctor should weigh in first for people with heart conditions or on blood pressure medicine.

Key Ingredients

• ForsLean is Coleus forskohlii, reportedly 500 mg of a 10% forskolin extract per serving. Trials are small, run 12 weeks and give mixed results
• Chromium comes as chromium polynicotinate. In meta-analyses it brings at most a small extra weight loss, and it does little for cravings in people without diabetes
• Cayenne pepper extract, which has a small effect on calorie burn
• BioPerine. Supplier-funded studies found it improved absorption of some nutrients, but it hasn't been tested with forskolin or chromium

We couldn't view the official label, so the doses above come from a third-party review of it and are unconfirmed.

Findings From the Forskolin Trials

In a 12-week trial of 30 overweight or obese men (Godard et al., 2005), body fat percentage and fat mass dropped with forskolin compared with placebo, while body weight held steady. Mildly overweight women in a comparable trial, also 12 weeks and funded by the ForsLean supplier, showed no significant change in body fat or weight. Diet and activity count for far more than any ingredient listed here.
