Why it was created

A meal-conscious routine,
made with Japanese fermentation.

Weight-management portfolios need products that feel practical, clear and easy to position without overpromising. Gymnema Sylvestre Calorie Block is built for that professional space.

The formula leads with fermented sake lees PROFIBER, then adds cyclodextrin, fermented tea powder and Gymnema sylvestre extract in a compact three-capsule daily format.

Important distinctionThe sources below examine individual ingredients, ingredient families or different preparations. They are not clinical trials of the complete Gymnema Sylvestre Calorie Block formula.
PROFIBERExploratory human report

Fermented sake-lees material and bowel regularity

A published Japanese review describes an exploratory intake report in 72 women with constipation tendencies using 750 mg of fermented sake-lees material. It is not a clinical trial of this finished formula and does not establish a guaranteed outcome.

PROFIBERPreclinical evidence review

Resistant protein, lipid binding and excretion

A scientific review summarises laboratory and animal work on indigestible sake-lees fractions, including lipid binding and increased faecal lipid excretion. These findings are preclinical and must not be read as a proven effect in people.

Gymnema sylvestreHuman ingredient study

Gymnema and metabolic-syndrome markers

A human study evaluated Gymnema sylvestre in people with metabolic syndrome. It concerns a specific preparation and population, not this finished product or this dose.

Cyclodextrin familyRandomised human study

Alpha-cyclodextrin and post-meal lipids

A randomised study examined alpha-cyclodextrin and acute postprandial lipid response. The product label declares cyclodextrin generally, so the publication is context, not equivalence.

Green teaSystematic review

Green tea and weight-management research

A Cochrane review found small and clinically limited effects of green tea preparations in overweight or obese adults. It does not test this fermented tea powder.
