2 EASY STEPS FOR MAXIMUM WEIGHTLOSS RESULTS

STEP ONE:
Reduce calorie absorption
ID-alG ™ blocks up to 77% of carbohydrate and 63% of fat digestion enzymes
That means your body won’t absorb all the calories from your food, helping you loose weight even without changing your habits.
STEP TWO:
Boost your metabolism
A slow metabolism burns fewer calories, that’s why some people have difficulty losing weight by just cutting calories or working out.
A fast metabolism burns calories at a quicker rate, helping you burn more calories 24/7.
Metabolism Booster Extreme and OK!FatBurn
HOLISTIC SOLUTION that addresses the 2 stages of food processing in the body – digestion and metabolism

8-in-1 formula with ProGarcinia™ supresses lipogenesis – the process of storing excess energy as fat
Garcinia contains hydroxycitric acid (HCA), a natural compound with a high proportion of hydroxycitric acid that reduces fat storage in the body. With added bilberry, gymnema sylvestre, L-carnitine, guarana, magnesium, zinc and kelp – this formula is the ultimate choice for speeding up your weight loss results!
OK! FatBurn with triple action promotes weight and fat loss
ID-alG™ is a patented formula of brown seaweed extract that inhibits the activity of two main digestive enzymes, lipase and amylase. Additional power from L-carnitine and L-tyrosine. Vitamin C acts as an antioxidant, protecting cells from oxidative stress.
Together they:
- Contribute to reduce the storage of excess energy as fat in the body
- Reduce sense of appetite helping you loose weight with less effort
- Supress the lipogenesis and their accumulation in the body
- Reduce calorie absorption from fat and carbohydrates
- Reduce food intake reducing cravings
- Induce weight loss
