About this study

This two-cohort study will evaluate a novel supplement developed for metabolic support using measures of glycemic variability, fasting glucose, and fasting insulin. In the first cohort, over the course of two weeks, these endpoints will be determined by continuous glucose monitoring (CGM) and blood/urine analyses in healthy adults using a carbohydrate blocking supplement (CBS). Following an interim analysis, the CBS will be evaluated for an additional two months in healthy volunteers using the same measures outlined above.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Treatment and study plan

Carbohydrate blocking supplement (CBS)

Dietary Supplement

The CBS is composed of a Hypromellose outer shell, and filled with mulberry leaf extract, berberine HCl, cinnamon bark powder, and cinnamon bark essential oil.

Mulberry leaf extract (Reducose) - 250 mg Berberine HCl (97%)(Berberis aristata root extract)- 25 mg Organic cinnamon powder (Cinnamon (Cinnamomum loureirii) bark powder) - 20 mg Essential oil blend (Grapefruit (Citrus paradisii) peel oil, Lemon (Citrus limon) peel oil Peppermint (Mentha piperita) aerial (leaf/stem) oil), Ginger (Zingiber officinale) root oil, Cinnamon (Cinnamomum zeylanicum) bark oil) - 5 mg

placebo capsule

Dietary Supplement

The placebo is composed of a Hypromellose outer shell filled with extra virgin olive oil.
