Great Product for Gut Issues

I'm so glad I found R's KOSO. It has helped me with my gut problems. I feel so much better.

It’s pleasant tasting, and you need about an ounce per serving, but after three days, I did not feel strong benefit. Left me a bit bloated, but I am going to continue to see if my digestion improves.

Deeply appreciated the Koso Team’s quick response to my request for an early delivery.

Best product ever, would recommend

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

I LOVE R's Koso!

I've been enjoying the great taste of R's in my daily glass of warm water in the moring! It's become a staple of my overall health regimen and I look forward to many years of this delicious, nutritious drink :)

I yous this only 3 times
I think it is a good product
I will know more when I use it appropriately

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

Bottle is very small

I expected more for the price

Not ordered but shipped

I like R’s Koso but do not use as quickly as you ship. I have been grateful for notifying me when a shipment is processing so I can adjust if needed. This last time it shipped without me seeing a notification. I now have several bottles and do not need any for a while. I do tell friends about your product and they are interested but slow to order.

Rs Koso Low Sugar is awesome

Rs Koso Low Sugar is part of my daily routine. It keeps me regular, tastes fine and doesn't compromise the diet I am on. I highly recommend Rs Koso for everyone!

I love it

I like the taste!

Feel so much better.

My coworker told me about koso and I’ve been using it for almost 2 years. I recently got a new assignment and I went a month without it and I definitely felt not having it, and once I was back on it I felt so much better. have a lot of gut issues and this is the best probiotic I’ve ever used. I highly recommend it. And the staff the are kind work with me when I have to change addresses with my job and answer my emails right away. So not only a great product but great customer service.

Love Koso

Love Koso ❤️ I am feeling so much better since taking it every morning as recommended. I have no stomach issues and I feel better.

Really enjoy this beverage

This is my beverage of choice for an evening treat ritual, delicious self care.

Doesn’t taste great but it seems to be working so far!

Didn’t find any difference

After trying 3 days cleanse process, couldn’t find any different feeling in my body. I think drinking that much drink for entire three days is not healthy for body. It’s just my experience, hope the others get the best out of it.

Helps my gerd

I tried Koso for 3 days detox and yes I lost some weight but most importantly I felt good. After that I’m using Koso for supplements since I have Gerd problem (gastric acid reflux) and so far it helps me a lot.

Tough to get down

There is a very distinct odor and taste. Almost a sickeningly sweet taste but also very earthy or like dirt. The odor really makes it tough to swallow down. I’ve been struggling so I haven’t been consistent to be honest.

Don’t think it’s worth the price

I’m not sure this really did anything for me. I’m almost done with bottle and noticed no real change. Maybe it “worked” for others. I won’t buy it again.

First Bottle🎉😍

I’ll be getting more after I used it as my breakfast replacer for a few weeks. I noticed I’m less bloated and have softer less inflamed skin-which is a win for someone with eczema.

An essential part of my day!

Whether I am making a refreshing drink or sustaining a cleansing fast, KOSO has become a basic component of my daily life. I especially love the concentrated lower sugar option.
