Bifidobacterium lactis

A friendly probiotic strain that supports smooth bowel movements, gut barrier strength, and natural immune defences.

What it is

Bifidobacterium lactis is one of the most thoroughly studied friendly bacteria found in healthy human guts and yoghurt. In Velobiotics supplements, each strain gets a tiny micro-shield against stomach acid so live cells arrive safely in your lower gut where they do their best work.

Also known as: B. lactis, Bifidobacterium animalis subsp. lactis

Key benefits

  • Supports regular bowel movements, so food moves smoothly through your gut.
  • Strengthens your natural immune system, so your body resists everyday bugs.
  • Keeps your gut lining strong, which means harmful substances stay out of your bloodstream.
  • Helps balance cholesterol levels, which supports overall heart and blood sugar, weight and energy balance.

Amplified by probiotics

Bifidobacterium lactis works alongside other friendly gut bacteria like Lactobacillus. By digesting fibre from your food, it produces beneficial organic acids that nourish your colon cells and keep unwanted microbes away. A microscopic protective layer shields each bacterium during digestion, helping it settle in your gut to support total digestive wellness.

Typical dose

1–20 billion live bacteria (CFU) a day

The evidence

Evidence: strong

Clinical studies show that Bifidobacterium lactis speeds up slow digestion and supports comfortable bowel habits in adults. Human studies also show it strengthens immune response and supports respiratory health. (Cassís-Nosthas ML 2026, J Vis Exp) (Chen K 2026, Front Nutr) (Beskow CB 2026, Nutr Hosp)

Safety & who should check first

Bifidobacterium lactis is exceptionally safe and gentle for daily intake. It is suitable for adults, children, and pregnant or breastfeeding mothers. If you have a severely weakened immune system, speak to your doctor before taking probiotics.
