XLS-Medical Max Strength tablets reduce calorie intake from carbohydrates, sugar and fat. They contain Clavitanol, a patented natural complex which reduces the break down and absorption of these nutrients. This results in a reduced calorie intake which helps you to lose more weight than dieting and exercise alone. It's clinically proven. In addition, the reduced absorption of dietary carbohydrates helps stabilise blood glucose and insulin levels, which helps in reducing food cravings and blood glucose management. This is a 5 day trial pack containing 20 tablets. Always read instructions before use.
