Both serum and whole blood samples were refrigerated and sent to Quest Diagnostic Labs (Ann Arbor, MI) for clinical analysis. It regulates the body's thermogenic response to food, increases the body's basal metabolic rate, and increases utilization of body fat. However, there are serious concerns over their safety and effectiveness. A chemistry profile was run on these samples using an Immulite Mark 5 HSS chemiluminescence random access immunoassay analyzer (Diagnostic Products Corporation, Los Angeles, CA) following standard procedures.

In other words, for weight loss to happen, energy expenditure (calories out) must exceed energy intake (calories in), which is precisely what was determined in a small 2015 study (9). (Huge catch here: The test subjects' overall weight didn't change.). Forskolin-induced diarrhea appears to be mild, and symptoms reportedly disappear within 4 weeks of use (9). The results of lean body mass revealed an increased trend when compared to the placebo group (p = 0.097). One small study, published in the journal Obesity Research, had 15 overweight and obese men take supplements, while another 15 men took placebo pills. Decreases were observed in ALT and uric acid levels. This panel consisted of muscle enzymes [creatine kinase, phosphorus, calcium]; liver enzymes [direct bilirubin, total bilirubin, gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), alkaline phosphatase, AST (SGOT), ALT (SGPT)]; lipid profile [triglycerides, total cholesterol, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), cholesterol/HDLC ratio, glucose], electrolytes [sodium, potassium, chloride, carbon dioxide, urea nitrogen (BUN), creatinine, BUN/creatinine ratio], protein status [uric acid, total protein, albumin, globulin, albumin/globulin ratio], and whole blood cell counts [hemoglobin, hematocrit, red blood cell counts, white blood cell counts (basophils, absolute basophils, eosinophils, absolute eosinophils, monocytes, absolute monocytes, lymphocytes, absolute lymphocytes, neutrophils, absolute neutrophils), platelet count, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW)].

This means that it widens blood vessels, such as veins and arteries, by promoting the relaxation of the muscles within their walls, thus improving blood circulation (8). Pharmacodynamic effects of inhaled dry powder formulations of fenoterol and colforsin in asthma. The upper left panel depicts changes in DEXA total scanned mass (g), the upper right panel illustrates changes in DEXA fat-free mass (g), the lower left panel highlights differences in DEXA lean mass (g), and the lower right panel shows changes in DEXA % body fat from Week 0 to Week 12 for CF () and P ().

Forskolin is believed to promote the production of hormone-sensitive lipase, an enzyme involved in moving stored triglycerides and releasing fatty acids so your body can use them for energy (8).
