Bifidobacterium infantis

A friendly gut bacterium that supports comfortable digestion, calms gut irritation, and balances immunity.

What it is

Bifidobacterium infantis is a beneficial probiotic strain naturally found in human digestive tracts. It is especially skilled at breaking down complex plant fibres and milk sugars. In Velobiotics products, a special micro-shield protects each bacterium from harsh stomach acid so it reaches your gut alive.

Also known as: B. infantis, Bifidobacterium longum subsp. infantis

Key benefits

  • Breaks down complex fibres, so your gut bacteria stay well nourished.
  • Supports a calm immune response, which helps reduce gut irritation.
  • Eases occasional gas and bloating, so your tummy stays comfortable.
  • Protects your gut lining, which keeps your digestive wall strong.

Amplified by probiotics

Bifidobacterium infantis works alongside other friendly gut bacteria to keep your digestive system balanced. As it ferments plant fibres, it produces nourishing compounds that lower gut acidity and keep unwanted microbes away. The micro-shield around each live bacterium ensures it arrives safely in your bowel to nourish your gut cells.

Typical dose

1–10 billion live bacteria (CFU) a day

The evidence

Evidence: strong

Human research confirms that Bifidobacterium infantis supports bowel comfort, eases bloating, and strengthens the gut lining (Chambers LM 2026, Gynecol Oncol) (Cassís-Nosthas ML 2026, J Vis Exp) (Parrino J 2026, Front Nutr).

Safety & who should check first

Bifidobacterium infantis has a strong safety record for adults and children. Some people experience mild, temporary changes in bowel habits when starting. Speak to a doctor first if you have a severely compromised immune system.
