I'm a Bristle paying customer, and love the entire conceptual area of microbiomes and self-directed assays. IMHO microbiome science provides a new kind of quantification of health and wellness, and suggests new vectors for treatments and feedback, and can even help enable discoveries of experimental confounders and colliders.
Thanks so much for your support! You’ve said it beautifully, and we are driven by the potential of the microbiome to better guide health and treatment decisions, and ultimately improve lives.
For a good introduction I suggest the paper "Oral microbiome: Unveiling the fundamentals" at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6503789/
