Oral Health Formulas

Mixed products combining CoQ10, xylitol and oral probiotics for gums and cavities. Individual ingredients have some trial support as adjuncts to dental care, but the blends as sold have not been tested and none replaces brushing, flossing or a dentist.

Evidence last reviewed: August 2026

What the science says

  • CoQ10 alongside gum treatment Limited evidence

    A systematic review with meta-analysis of adjunctive coenzyme Q10 in non-surgical periodontal treatment found small improvements in probing depth and attachment level. The trials were few, small and short.

  • Xylitol and cavity prevention Limited evidence

    A systematic review of xylitol for caries prevention found inconsistent results and low-certainty evidence, in line with earlier Cochrane assessments. Any benefit appears tied to chewing gum use rather than to xylitol in a capsule.

  • Oral probiotics for gum inflammation Moderate evidence

    An umbrella meta-analysis of probiotic supplementation in periodontitis treatment reported modest additional reductions in inflammation and pocket depth when added to scaling and root planing. Benefits fade after supplementation stops.

Dosage & safety

Studied doseStudied doses: CoQ10 around 60–120 mg daily as an adjunct; xylitol roughly 5–10 g daily split across chewing occasions; probiotic lozenges typically 1–2 billion CFU of Lactobacillus reuteri or Streptococcus salivarius daily.
SafetyXylitol causes gas and diarrhoea above roughly 20–30 g a day, and is dangerous to dogs even in small amounts. CoQ10 may slightly reduce warfarin effect. Probiotics should be used cautiously by people who are severely immunocompromised. None of these substitute for dental treatment of active disease.
