African mango (Irvingia gabonensis) is a natural substance often marketed as a weight-loss aid. African mango supplements typically contain extracts of the seeds of the African mango tree (a plant native to West Africa). African mango seeds are known to contain a variety of nutrients, including fiber, amino acids, essential fatty acids and minerals.
Uses for African Mango
African mango is purported to promote weight loss by suppressing appetite, speeding up metabolism and preventing fat buildup.
Benefits of African Mango
To date, few scientific studies have tested the health effects of African mango. However, some research suggests that African mango may help protect against obesity and enhance metabolic health.
For instance, in a 2009 study in Lipids in Health and Disease, researchers found that participants who took African mango every day for 10 weeks experienced significant improvements in body weight, body fat, waist size, cholesterol levels, blood sugar levels and levels of C-reactive protein (a marker of inflammation). The study involved 102 healthy overweight or obese people; half of participants received African mango, while the other half were given a placebo.
Additionally, a 2008 study in Lipids in Health and Disease indicated that taking a combination of African mango and cissus (an herb long used in ayurvedic medicine) may help fight obesity. Every day for 10 weeks, 72 obese or overweight participants took capsules containing one of three substances: a placebo, the African mango/cissus combination or cissus alone. By the study's end, members of the African mango/cissus group showed the greatest reductions in body weight, body fat, waist size and cholesterol levels.
In animal-based research, scientists have determined that African mango may fight obesity by inhibiting the development of fat cells.
Is African Mango Safe?
Little is known about the safety of long-term use of African mango. There's some evidence that African mango may trigger mild side effects, such as headache, dry mouth, sleep disturbance and gastrointestinal problems.
Where to Find African Mango
Widely available for purchase online, supplements containing African mango are sold in many natural-food stores and in stores specializing in dietary supplements.
Should You Use African Mango for Weight Loss?
Due to a lack of supporting research, it's too soon to recommend African Mango for weight loss. If you're looking to lose weight, the National Institutes of Health recommends following a weight-management plan that pairs healthy eating with regular exercise. Keeping a food diary, getting eight hours of sleep each night and managing your stress may also help you reach and maintain a healthy weight.
If you're considering the use of African mango for a chronic condition (such as diabetes), make sure to consult your physician before starting your supplement regimen. Self-treating a chronic condition with African mango and avoiding or delaying standard care may have serious consequences.
