Lactobacillus salivarius

A fast-growing probiotic strain that supports oral hygiene, gum integrity, and intestinal microbial balance.

What it is

Lactobacillus salivarius (Ligilactobacillus salivarius) is an indigenous lactic acid bacterium naturally abundant in human saliva, oral cavity, and intestinal tract. Produced through anaerobic fermentation and freeze-drying, L. salivarius is recognized for its rapid growth rate and high production of bacteriocins, lactic acid, and hydrogen peroxide. Formulated in Velobiotics supplements, L. salivarius is protected by patented MEP microencapsulation, shielding cells from gastric fluid for delivery to the intestine.

Also known as: L. salivarius, Ligilactobacillus salivarius

What it does

  • Inhibits periodontopathic bacteria to support healthy gums and breath.
  • Produces salivaricin bacteriocins that suppress opportunistic pathogens.
  • Reduces inflammatory cytokine production in mucosal tissues.
  • Helps maintain healthy intestinal microflora balance.

Amplified by probiotics

Lactobacillus salivarius provides rapid antimicrobial and acidifying synergy within probiotic formulations. Due to its fast doubling time, L. salivarius quickly colonises mucosal niches, secreting large quantities of L-lactic acid and salivaricin bacteriocins. This rapid acidification lowers luminal pH, immediately suppressing acid-sensitive bad bacteria and creating a favorable substrate environment for slower-growing Bifidobacteria species. L. salivarius also degrades proinflammatory bacterial endotoxins in the gut lumen, protecting the mucosal lining from immune overactivation. When paired with Lactobacillus acidophilus, it reinforces mucosal cell-to-cell tight junctions. Shielded by Velobiotics MEP lipid microencapsulation against stomach acid, L. salivarius maintains cell viability to promote intestinal and systemic health.

Typical dose

1–10 billion CFU/day

The evidence

Evidence: strong

Human clinical trials show that Lactobacillus salivarius supplementation significantly reduces plaque formation, bleeding on probing, and periodontal pathogens in oral health. Clinical studies also confirm its efficacy in modulating gut inflammation and supporting intestinal microflora balance.
