Lactobacillus salivarius

A fast-acting friendly bacteria strain that supports fresh breath, healthy gums, and gut balance.

What it is

Lactobacillus salivarius is a beneficial strain of friendly bacteria from the yoghurt family naturally present in human saliva and the digestive tract. Known for growing quickly, it produces natural organic acids and protective compounds called natural germ-fighting substances. Protected inside Velobiotics micro-shields (MEP microencapsulation), these live bacteria pass safely through stomach acid to support both oral and gut health.

Also known as: L. salivarius, Ligilactobacillus salivarius

Key benefits

  • Supports healthy gums and fresh breath by keeping unwanted oral bacteria in check.
  • Produces natural protective compounds that shield your digestive tract from bad bacteria.
  • Helps calm gut-lining inflammation, promoting comfortable digestion and tissue health.
  • Keeps your gut bacteria in balance, so your digestive system stays on track.

Amplified by probiotics

Lactobacillus salivarius multiplies rapidly, making it a powerful ally for your digestive system. It quickly secretes natural lactic acid to lower gut pH, making life difficult for harmful bacteria while preparing a welcoming home for slower-growing friendly strains. When paired with strains like L. acidophilus, it reinforces your gut lining and keeps your gut calm.

Typical dose

1–10 billion live bacteria (CFU) a day

The evidence

Evidence: strong

Human studies confirm that Lactobacillus salivarius helps maintain gum health, reduces dental plaque, and supports fresh breath. Clinical studies also demonstrate its ability to soothe gut inflammation and maintain a healthy bacterial balance (Ushizawa E 2026, Front Nutr) (Wang Y 2026, Can J Gastroenterol Hepatol) (Vasoglou G 2026, Eur J Orthod).
