Good Bacteria is a doctor-formulated supplement brand aimed at promoting gut biodiversity. Gut biodiversity is the strongest indicator of a healthy, resilient gut microbiome. Traditional probiotics, with limited controlled strains, may lead to monocultures in the gut. 

Good Bacteria launched the first daily synbiotic where the formulation changes weekly. Every month you are shipped a 28-day supply that includes four unique blends of probiotic strains, prebiotic fibers, and a postbiotic. Sachets are labeled Week 1 through Week 4 and are designed to be taken daily, in sequence, to restore microbial diversity and support lasting gut health.

Founder and CEO Anabel González started Good Bacteria after a profound postpartum health struggle. She felt depleted in a way she’d never experienced, drained of energy and no longer feeling at home in her own body. Her path to healing came through learning about the gut microbiome and fermenting foods at home. Restoring microbial diversity transformed her health, energy, and sense of self. Good Bacteria was born from that experience: a desire to make the benefits of gut diversity accessible in a simple, daily ritual.

BrandProject led Good Bacteria’s pre-seed round in 2024.
