Why It Works

Benefits

This yakult probiotic supplement delivers dual-strain support through Yakult's proven cultivation technology.

1

Supports Comprehensive Gut Health

This supplement delivers two distinct probiotic strains that work in different parts of your digestive system. Lactobacillus casei Shirota primarily supports the small intestine, while Bifidobacterium breve BY targets the large intestine. This dual-action approach provides gut health probiotic coverage across your entire intestinal system.

Strain-specific dual action

Delivers Live Bacteria to Intestines

Through Yakult's proprietary strengthened cultivation technology, both probiotic strains are fortified to survive harsh stomach acid and bile. Unlike regular bacteria that are typically killed during digestion, these strengthened strains reach your intestines alive to deliver their probiotic supplement benefits effectively.

The Science

How It Works

Understanding how this dual-strain yakult probiotic supports your intestinal health.

Dual-Strain Intestinal Coverage

Dual-Strain Intestinal Coverage

This supplement contains two complementary probiotic strains targeting different intestinal regions. Lactobacillus casei Shirota, the same strain found in Yakult drinks, primarily works in the small intestine. Bifidobacterium breve BY, found in Milmil products, primarily works in the large intestine.

Together they provide dual coverage - what the maker describes as reaching both intestines with a "W" (double) approach.
Strengthened Cultivation for Survival

Strengthened Cultivation for Survival

Regular probiotic bacteria are typically killed by stomach acid and bile before reaching the intestines. Yakult's strengthened cultivation technology fortifies both L. casei Shirota and B. breve BY strains so they can withstand the harsh digestive environment.

This allows them to reach your intestines alive, where they can deliver their beneficial effects.
Supporting Daily Intestinal Health

Supporting Daily Intestinal Health

The intestines serve as a critical gateway in your body. They provide:
  • Physical defense - blocking unwanted substances
  • Beneficial bacteria partnership - hosting microorganisms that support overall wellness
  • Nutrient absorption - absorbing essential nutrients to deliver throughout your system
By delivering live probiotic strains directly to both intestinal regions, this supplement supports these natural intestinal functions.

Probiotic Strain Research

LACTOBACILLUS CASEI SHIROTA

Yakult's signature probiotic strain, named after Dr. Minoru Shirota who founded Yakult. This strain has been the focus of Yakult's research for decades and is the same bacterium used in Yakult probiotic drinks consumed by millions worldwide. Through strengthened cultivation, it survives digestive acids to reach the small intestine alive.

BIFIDOBACTERIUM BREVE BY

The probiotic strain used in Yakult's Milmil products. Like L. casei Shirota, it undergoes strengthened cultivation to survive the harsh digestive environment.
