Feel much more AWAKE!

I’ve been drinking Rs KOSO for about 6 weeks now, first thing in the morning, ( 1-2 tbsp with seltzer water) a shot in the afternoon and sometimes before bed .I haven’t lost weight ( I love food too much, to do a 3 day cleanse ) . I will admit I feel lighter though, more alert. I sleep better and have more energy. Lately I’ve noticed not having the afternoon slump. I love this drink!! I highly recommend! Maybe I will someday do the 3 day cleanse. 😁

KOSO low sugar Japanese Postbiotic drink Review

I take KOSO once every morning and before I go to sleep in evening and have been feeling great ever since! I love the taste and it’s so easy to mix with water. I would highly recommend this drink to anyone, you will not be disappointed!

Tastes Good

Glad there is a lower sugar option.

Love the little bottles

I love these little bottles because they are pre portioned , also love the labels reminding me of the benefits. My kids love the little bottles just because they are cute!! Thank you for this life giving, valuable mothers day gift!

Great taste

I love the R’s Koso Shots. Great taste, no need to mix, love the convenience plus it greatly helped with digestion and reduced bloating. I only wish the price wasn’t so expensive. Drinking the recommended two shots per day won’t last the month so $79 is pricey.

Very good morning start drink 👍

Great test

Great for travel

Packaging perfect for travel.

Great taste that’s a pluss and simple to understand. Will buy again

Enjoying it

It helps me to not be hungry

Best addition to daily life!

This drink has been the best and easiest addition to my daily routine. After only 2 weeks, I feel more energized, I’m sleeping better, my skin is clearing up, and I even lost a couple pounds. I’m so impressed with this drink and very thankful to have found it! Arigatou gozaimasu!

Smell and taste not for me..

I am having a hard time with the smell and the taste. No idea if it works since the smell and the taste in the sparkling water or filtered water make me not want to take it.

Clearer facial skin

Have had chronic acne problems on face for decades. Now it's clearer than it's ever been. So grateful for this product.

An easy way to improve gut health

I have been enjoying RS Koso in a glass of sparkling water each morning. It is a simple way to improve gut health which is so impactful for all of us. I feel that my digestion process is improving and I look forward to the ongoing benefits of RS Koso.

I love this stuff. I drink it woth mineral water. I am going to try a 3 day cleanse next.

Will Try Again At A Different Time

It didn't really do much for me, but perhaps I didn't prepare myself for it properly -- I will try the same product again at a different time.

Not sure it’s really doing much of anything

It isn’t unpleasant, just an unusual flavor for the American palate. I have gotten accustomed to it - it’s fine. That said, I cannot say it is helping my health with any firmness. I’ll finish the bottle (just cannot see wasting it) because it’s so expensive but will not order again.

Absolutely Amazing!!!

I saw this in an ad and thought I would give it a try. I have struggled with digestive issues, my whole life when I use anything with psyllium husks, I noticed that after I stop using it, my digestive issues go back to where they were. I jumped right in with the. koso started with the day fast. I could not believe how much energy I had and what was most shocking was the next day even without having any food I was able to go to the bathroom with ease and that has continued these past few days. I have been replacing my breakfast with. Koso just because I love how it makes me feel. This is definitely something that I’m going to keep taking!!! I am going to do a day cleanse for the next three weeks and once my body is adjusted, then I’m going to dive into a three day cleanse and can’t wait to see how I feel after that.

Pricey but it seems to be working for my bowels. FYI this is not Jerry

It's ok.

Too early to review I don't notice any changes to my body except I have to fart multiple times a day big smelly ones 😂

It tastes good and I feel like I am doing something good for my body. I feel energized since I started. It is a new morning routine.

Loving R's Koso

We tried R's Koso on the recommendation of a friend, I was hesitant at first due to the USD cost and shipping costs to Australia but after trying this we will definitely be repurchasing. The difference in bloating was almost instant and we both have noticed a significant improvement in our overall gut health. Please find a reseller in Australia!
