By week four I could see a noticeable decrease in my appetite, and my mood has improved significantly. It's amazing how much of a difference it makes when your body starts burning fat more efficiently.

After years of trying various diets and exercise routines with little success, I was feeling frustrated and defeated by my slow metabolism. After using these two, I finally shed some pounds, but I also feel more energized and motivated to keep pushing forward in the gym.

2 EASY STEPS FOR MAXIMUM WEIGHTLOSS RESULTS

Metabolism Booster Extreme + OK!FatBurn

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

Metabolism Booster Extreme + OK!FatBurn

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 scientifically proven active ingredients

Magnesium

1. Magnesium

Magnesium plays a key role in maintaining the normal functioning of the nervous system and muscles and supports energy metabolism and electrolyte balance. With magnesium citrate, the form that allows the best absorption and bioavailability, you can replace lost magnesium and avoid deficiencies.

Guarana and Garcinia Cambogia

2. Guarana and Garcinia Cambogia

Guarana provides a sustained energy boost and stimulates fat metabolism, contributing to weightloss. Garcinia cambogia (Garcinia gummi-gutta) contains hydroxycitric acid (HCA), a natural compound that inhibits the enzyme lipase, which is responsible for fat breakdown in the body. This helps in preventing fat accumulation and weight loss in the body.

ID-alG™

3. ID-alG™

ID-alG™ is an extract of the brown seaweed Ascophyllum nodosum, which is rich in long-chain polyphenols called phlorotannins. They help to inhibit the action of the two main digestive enzymes, lipase and amylase, and block up to 77%* of carbohydrate digestion and 63%* of fat digestion.

Gymnema sylvestre extract

4. Gymnema sylvestre extract

Gymnema sylvestre is a plant used in traditional practices, commonly known as "gurmar," which roughly translates to 'sugar destroyer' in Hindu. The leaves of Gymnema sylvestre contain gymnemic acid, a compound known for selectively inhibiting sweet tastes, which may help reduce the desire for sweetness.

Kelp

5. Kelp

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

Zinc

6. Zinc

Zinc contributes to normal immune function, contributes to normal DNA synthesis and cell division, helps protect cells from oxidative damage, helps maintain normal bones and contributes to normal cognitive function.
