Lactobacillus gasseri

A specialised friendly bacterium that supports healthy belly fat balance, digestion, and vaginal health.

What it is

Lactobacillus gasseri is a friendly bacterium naturally found in a healthy human gut and intimate area. In Velobiotics supplements, live L. gasseri bacteria are grown gently and protected by a tiny micro-shield. This keeps them safe from stomach acid so they reach your lower gut and intimate areas intact.

Also known as: L. gasseri

Key benefits

  • Supports a healthy body weight and aids in managing visceral fat [deep belly fat].
  • Keeps intimate flora balanced and maintains a healthy, protective acidic pH.
  • Produces natural protective substances that stop bad bacteria from multiplying.
  • Soothes occasional stomach distress, gas, and abdominal bloating.

Amplified by probiotics

Lactobacillus gasseri works alongside other probiotic strains to make lactic acid, which keeps your gut environment healthily acidic. This acidic setting encourages other good bacteria to grow while keeping bad bacteria away. L. gasseri also teams up with strains like L. rhamnosus to build a strong mucus barrier on your gut wall, protecting your lining and helping your body use nutrients effectively.

Typical dose

1–10 billion live bacteria (CFU) a day

The evidence

Evidence: strong

Clinical studies show that taking Lactobacillus gasseri helps reduce waist size and visceral fat [deep belly fat] in adults. Research also confirms it helps balance natural intimate flora and supports digestive comfort.

Safety & who should check first

Lactobacillus gasseri is safe and well tolerated in human studies. Speak to a doctor or pharmacist first if you are severely immunocompromised or have a serious medical condition.
