ID-alG™ is a patented brown seaweed extract that blocks a certain number of enzymes that digest carbohydrates and fats. This reduces fats and carbs assimilation and contributes to significant weight loss. 1
OK!Fatburn is an effective weight loss formula that inhibits carb and fat digestion enzymes with the power of ID-alG™. The triple-action formula contributes to normal energy-yielding metabolism⁴ with added power of L-tyrosine and L-Carnitine. Studies confirm significant weight loss correlated with fat mass. 1
90% of lipid (fat) intake is hydrolyzed by lipases, while carbohydrate digestion is mainly carried out by the amylases. ID-alG™ inhibits amylase and lipase, which means reduction of carbs and fat assimilation from the nutrients you consume.1
Studies show that 76% believe ID-alG™ induces weight-loss and 72% would continue using ID-alG™. Users experience visible effects after 8 weeks of use with significant reduction in carbs assimilation. Real customers report they lost weight with OK!Fatburn and their testimonials prove its effectiveness.1

Triple-action formula with a brown seaweed extract for significant weight loss1
ID-alG™ is a patented formula of brown seaweed extract with unrivalled weight management properties.
It has exceptional properties due to the content of specific long-chain polyphenols called phlorotannins and inhibit the activity of the two main digestive enzymes:
ID-alG™ blocks a big part both amylase and lipase enzymes, which means reduction of carbs and fat assimilation – nutrients responsible for more than 85% of the caloric intake.
Blocks more than half of carbohydrate-digesting enzymes1
Thanks to ID-alG™, a patented brown seaweed extract, the product reduces the activity of the enzyme amylase, which is responsible for breaking down carbohydrates.¹
Blocks more than half of fat-digesting enzymes1
ID-alG™ also helps limit the action of lipase, the enzyme responsible for digesting fats.¹
Results, demonstrated by studies
In studies, ID-alG™ was shown to support weight loss, closely correlated with fat mass, and fat reduction when used consistently over 16 weeks.¹
Consumers’ satisfaction
Preliminary study questionnaires assess the satisfaction of users:
Step 1

Step 2
Stir vigorously until completely dissolved (1 min).
Step 3
Drink twice a day with food or an empty stomach.
Made from scientifically proven active ingredients
ID-alG ™ is a grape seed extract and an extract of the brown seaweed Ascophyllum nodosum, which is rich in long-chain polyphenols called phlorotannins. Ascophyllum nodosum reduces fat absorption and helps eliminate fat deposits, which consequently affects body weight.
L-carnitine is an amino acid derivative that plays a key role in the body’s metabolism of fat. It is a natural compound that is produced by the body itself or can be obtained from certain foods and dietary supplements.
L-Tyrosine contributes to the normal synthesis of catecholamines, including adrenaline, noradrenaline and dopamine.
Vitamin C contributes to normal collagen formation for the normal function of skin, and to the protection of cells from oxidative stress.
