BioLumen / Monch Monch
Advancing
Dr. Robert Lustig is co-founder and Chief Medical Officer of BioLumen, a company whose first product is Monch Monch, a microsponge fiber powder sold at monchmonch.shop. The product is marketed to reduce the absorption of sugar and starch in the gut while feeding gut bacteria — a commercial expression of Lustig’s long-standing fiber advocacy.
In an interview recorded in early January 2026 (published March 10, 2026), Lustig framed the strategy as harm reduction for ultra-processed food, saying it was “kind of like giving clean needles to drug addicts during the AIDS epidemic… you try to reduce the harm.” He said the company is working to get the fiber incorporated directly into ultra-processed foods themselves.
Disclosure: as a co-founder and CMO of BioLumen, Lustig holds a commercial interest in fiber supplementation — relevant context when citing his fiber advocacy. Independent 2026 confirmation of BioLumen beyond Lustig’s own statements and product-review coverage was not found in this research.
