Aloe Vera extract significantly decreases serum glucose and significantly increases serum insulin levels. It offers an attractive adjunctive strategy for impaired fasting glucose tolerance in conditions such as pre-diabetes /metabolic syndrome.
Other research found that Aloe Vera in people with pre-diabetes or early untreated diabetes, reduces body weight, body fat mass, and insulin resistance. Aloe Vera can also help reduce the levels of blood glucose and serum lipids in patients with advanced type 2 diabetes. Use up to 2 ounces per day of aloe gel.
