Meiji R1: The Yogurt Boosts Your Immune System

Every morning, when I eat breakfast, I definitely have a yogurt drink called “Meiji R1”.

Actually, the R1 yogurt is a kind of superfood from the leading Japanese food company Meiji, which comes in 2 types, ordinary yogurt form, and drinks.

Because of its benefits, Meiji R1 became a popular topic several years ago in Japan, together with the probiotic yogurt also from Meiji LG21.

Now widely consumed by many people, these yogurt products are available at almost any supermarket and convenience store around the country.

Health Benefits

The reason why Meiji R1 has gained deep-rooted popularity is that this probiotic yogurt literally has excellent health benefits.

The yogurt contains lactic acid bacteria producing lots of exopolysaccharides (EPS) called “OLL1073R-1”, and the EPS helps strengthen the immune system.

Exopolysaccharides activate natural killer cells (NK cells) that boost the ability of the immune system to fight against diseases such as cancer, flu, and common colds.

So the most expected effect of Meiji R-1 yogurt is to improve immunity. 

As proof of this, during the period spanning from September 2010 to March 2011, an extensive study program of the probiotic yogurt was conducted in Arita Town, Saga Prefecture,

where elementary school children were assigned to eat a cup of R1 yogurt every day.

As a result, their influenza infection rate amazingly dropped to 1/10 compared to the group of elementary school children who didn’t eat R1 yogurt at all.

Other Benefits

Not only that, but Meiji R-1 yogurt is also effective in improving intestinal environments, and prevents arthritis, rheumatism, and skin troubles as well.


Meiji R1 has such wonderful benefits, but to see its effects, you need to eat a cup or drink a bottle of it on a daily basis.

As for me, I have rarely caught a cold since I began consuming R1 yogurt every day.

    It is recomended for young age, like 5yrs old ? What happen if you drink more than 1 bottle of r1 yogurt drink ?

      Thank you for your comment.
      According to Meiji’s official website, R1 yogurt is recommended for people who are 1 year or older.
      I don’t find consciously that something has changed, but I think something like what I said in this
      article is going on inside the body.
      An important point is to have one R1 yogurt everyday.

    Would there be anywhere that would ship this to the US?

    • Tomo says:

      The yogurt can be kept in the fridge only for 2 weeks after it’s produced, and sorry, I couldn’t find online marketplaces that ship it abroad.
