The science

The strain nature gave healthy babies.

Until about age 10, bifidobacteria are the most common bacteria in a child’s gut. B. breve M-16V was discovered in a healthy infant’s intestine in 1963 by Morinaga Milk researchers — it feeds on milk oligosaccharides and tolerates lysozyme found in breast milk.

Questions, answered.

What age is Kids!Flora for?

It’s designed for babies and children from 6 months to 10 years. It’s also perfectly safe for older kids and adults.

Is it really made in Japan?

Yes. It’s produced by OSONE Co., Ltd. in Saitama Prefecture — an ISO 9001 and Health Food GMP certified facility.

What’s special about B. breve M-16V?

It was isolated from a healthy infant’s intestine in 1963 by Morinaga Milk and has been the subject of many scientific studies. B. breve is naturally abundant in healthy children’s guts.

How many live bacteria are in a sachet?

10 billion CFU at production, with more than 5 billion guaranteed until the expiry date when stored at room temperature.

How should I give it?

After a meal, mixed into cold or room-temperature milk — never a hot drink, as heat harms live bacteria. Don’t give it at the same time as antibiotics. Kids enjoy it like a sweet.

Does it need refrigeration?

No. Store at room temperature up to 30°C. Use soon after opening; leftovers keep about a week in the fridge.
