Irvingia Gabonensis, also known as African mango, has been used for over 200 years by tribes in West Africa as both a food and herbal medicine. Studies have shown that IG can help with weight loss, suppress appetite, lower cholesterol, and increase metabolism. A 2009 study found that a group taking 150 mg of IG daily lost 28 pounds in 6 weeks, compared to only 2 pounds lost by the placebo group. IG has also been shown to reduce blood pressure, cholesterol, and blood sugar levels. Researchers have concluded that IG is an effective appetite suppressant and can help improve metabolic health issues.
