tastes good works well. it’s just a little pricy compared to similar products. I love the bottle too.

Best thing I’ve done for myself in a while!

I’m very thankful for this drink because it truly helped me restart and regain my health! I love the taste. I love the transparency and the support of the company.
HIGHLY RECOMMEND! I even shared my 3 day cleanse on my socials and people could see a difference and feel my excitement. Planing on doing this more often

Delicious and Refreshing

I am over halfway done with my first bottle of Koso, but I absolutely love it! It smells strange, like grassy, but it tastes refreshing and fruity. I've noticed less bloating overall. I will continue to monitor my digestion to see if it improves that as well.

R's KOSO - Japanese Postbiotic Drink (474ml / 16oz)

Good product

I have been using the Koso once a day for my gut health. One of the fist thing I noticed is that it helped reduce bloating tremendously.

Excellent Product

I love the taste and felt the difference immediately. My bloating seems to be gone after consuming this product. It’s expensive but worth it. Glad I have found you!

I’ve used one bottle of KOSO but only once a day. I was told to use it twice a day. I’ll use the ...

I think it is a good product. Very unusual. I have only used one bottle.

1st time review

Try it for the 1st time.. very good taste and notice the detox benefits very quickly. Can't wait for the 2nd bottle

R's KOSO - Japanese Postbiotic Drink (474ml / 16oz)


tastes just right

Love the taste

I don’t take it as a meal replacement
But as an snack in between meals


I like it but I don’t have gut heath issues so it’s not worth the expense, didn’t make me lose any weight either

Love it!!

I been drinking Kodo 2weeks
I love the taste and everything.
It’s so refreshing and now it’s on my daily schedule.
I feel I have more energy as well!
I feel my got shrink then before !:)


This product is amazing, I was feeling very bloated and having stomach issues. After taking this in the morning for just a week it cleared up everything. I will definitely be buying this product again, want to try the fast next time around.

Fabulous ✨

Before I found out about R’s Koso I was taken a pill probiotic and it does not live up to Koso. When I finished the trial I knew I had to invest in the bigger bottle. I recently had skin issues with eczema and this helped tremendously!

It was good

Reason: seems to be quite a bit of sugar in the product.


I like the taste and it helps with digestion. It also helps with weight loss.

Best Tasting Pre- and Probiotic I've Had!

highly recommend for those who do not want to go full-on cleanse, but want to improve their gut health and detox in everyday life!

Worked like a charm especially after a few consecutive days~!!

I feel like this drink, when diluted with water per the instructions, softened everything in my gut and intestines and everything came through much easier and this helped me to start to lose some extra belly inches~!! And it's so rich with great nutrients and superfoods so when I can afford to, I will subscribe to the big version. :)))

I love it

My body feels more energize and skin feels smoothly and brighter after 3days I started drinking 30ml per day . I’m now waiting for new bottle to be delivered .
Only thing is I hope if there is another subscribe option for every 3 weeks since it won’t be enough for a month for people who drinks every day so😊
