Calorie Fighter – Blocks calories, maintains balance!

Calorie blocking meets weight control – the ultimate combo!

Calorie Fighter helps reduce calorie intake from fat, sugar, and carbohydrates, so you can support your weight balance effortlessly.

✔ Revolutionary and patented formula consisting of Omtec50® (Chitosan derived from fungi (Aspergillus niger)) and OmtecXS® (white kidney bean extract (Phaseolamin)).
The active ingredients are Omtec50® and OmtecXS® extract. Omtec50® is a natural fibre with a high capacity to bind lipids, helping to neutralise calories from high-fat foods. OmtecXS® extract inhibits the starch-digesting enzyme pancreatic alpha-amylase, interrupting the carbohydrate digestion process.

Because balance starts from within – with Calorie Fighter!

Your questions answered

What does it mean for a product to be a medical device?

Medical devices are products intended to prevent, alleviate or treat a condition. In the UK they are regulated by the MHRA and must carry a UKCA or CE marking. Always read the enclosed leaflet, which tells you how long you can use the product.

How long does one pack last?

It depends on the product and dosage – see the How to use section and the enclosed leaflet. For Calorie Fighter and Fat Fighter, one pack of 30 tablets lasts 5 days at the recommended dose of 2 tablets 3 times a day.

Can I combine a medical device with other Slim Boost products?

Yes, but don't use Calorie Fighter and Fat Fighter with the same meal, and always follow the directions and limitations in the leaflet for each product. If you take medication, talk to your doctor before use.
