Biome Shield Toothpaste
Two natural active ingredients — paeoniflorin and quercetin — chosen for published research on the bacteria and inflammation behind bleeding gums. SLS-free, triclosan-free, fluoride-free, and it tastes like toothpaste.

A clean that works where it matters.
Built around the biology rather than the sensory cues — which is why the ingredients most tubes carry to generate lather simply weren’t needed.
Ingredients with integrity.
Two natural actives, each chosen for published research on exactly this problem — and named on the carton rather than buried in a list.

A naturally occurring compound from the root of the peony, and the centre of Professor Rabie's own research into plant-derived actives.

A flavonoid found widely in fruits and vegetables, and among the more extensively studied natural compounds in the literature.
1Paeoniflorin is a naturally occurring compound from the root of the peony, Paeonia lactiflora, and a focus of Professor Rabie's published research into plant-derived actives. Described as studied, not proven.
2Quercetin is a plant flavonoid found widely in fruits and vegetables; peer-reviewed work has examined its activity against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans, species associated with periodontal disease. Studied, not a treatment claim.
