Do you know some of the reasons for being overweight?

In today’s time, there are several reasons for being overweight:

  • Processed foods, such as fast food, sugary drinks, and snacks, which are often high in calories but low in nutrients.
  • Sedentary lifestyle and lack of exercise.
  • Lack of sleep and irregular sleep patterns.
  • Large portion sizes and eating out, as restaurant and fast food meals tend to have larger portions and we have less control over the ingredients and quantities.
  • Stressful situations and resorting to snacks.
  • Hormonal imbalance.
  • Lack of awareness or misinformation about healthy eating habits.

 

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. 1

Additional power from L-carnitine and L-tyrosine.

Vitamin C acts as an antioxidant, protecting cells from oxidative stress. It contributes to the normal functioning of bones, teeth, cartilage, gums, skin, and blood vessels. 4

Premium natural ingredients with proven effects

ID-alG™

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.

L-Carnitine

L-Carnitine

L-carnitine is an amino acid that is crucial for fat metabolism because it ensures that long-chain fatty acids are transported to the mitochondria where they are converted into energy.

L-Tyrosine

L-Tyrosine

L-Tyrosine contributes to the normal synthesis of catecholamines, including adrenaline, noradrenaline and dopamine.

Vitamin C

Vitamin C

Vitamin C is an important antioxidant that protects our cells from oxidative stress. It is necessary for the normal functioning of bones, teeth, cartilage, gums, skin and blood vessels.
