2 EASY STEPS FOR MAXIMUM WEIGHTLOSS RESULTS

Product image

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

Product image

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

This is the ultimate choice for speeding up your weight loss results!

Metabolism Booster Extreme and OK!FatBurn will help you most, if you:

 

  • spend a lot of time sitting, at work or at home
  • can’t manage to lose weight even if you watch what you eat
  • want to increase the effects of physical activity
  • want to get rid of extra pounds in a natural way
  • want to increase the effects of your diet

Made from quality ingredients

Magnesium

1. Magnesium

Magnesium contributes to the normal functioning of the nervous system and muscles, normal energy-yielding metabolism, and also supports electrolyte balance.

Guarana and Garcinia cambogia

2. Guarana and Garcinia cambogia

Guarana is known for helping maintain normal body weight. It is also an energy source and helps you feel more energetic. Garcinia cambogia (Garcinia gummi-gutta) extract contains hydroxycitric acid (60% HCA), which inhibits lipogenesis and fat accumulation in the body. Garcinia helps regulate body weight, reduces fat buildup, and decreases feelings of appetite.

Gymnema sylvestre extract

3. Gymnema sylvestre extract

Gymnema sylvestre is a plant used in traditional practices, commonly known as “gurmar,” which in Hindi means “sugar destroyer.” Its leaves contain gymnemic acid, a compound known for selectively suppressing sweet taste, which may help reduce sugar cravings.

ID-alG™

4. ID-alG™

ID-alG™ is a combination of grape seed extract and brown seaweed (Ascophyllum nodosum) extract, which is rich in long-chain polyphenols called phlorotannins. Ascophyllum nodosum reduces fat absorption and helps eliminate fat deposits, which in turn affects body weight.

Kelp

5. Kelp

Kelp (Ascophyllum nodosum) is a large seaweed that grows in nutrient-rich underwater habitats in shallow oceans. It is a source of iodine, which plays a role in thyroid hormone production and normal thyroid function. Iodine also supports cognitive function and the nervous system.

Zinc

6. Zinc

Zinc supports the normal function of the immune system, normal DNA synthesis and cell division, helps protect cells from oxidative stress, and contributes to maintaining normal bones and normal cognitive function.
