I am a second year cancer survivor and needed to get my gut back to normal. I saw and review the information from the website and had to try it. All I can say is wow! I felt on day 3 having energy! When I are, I didn’t feel so full, couldn’t move for the rest of the day. I would eat, full full, have energy, start workout and moving again. The price is what stopped me at first but totally worth every penny to be able to move and have energy again I hope this company stay in busy and help anyone with digestion issue. Thank you!!

So far I like the product. It tastes between plum wine and balsamic without the vinegar burn. Mixed with sparkling water it is not that bad. I look forward to the health benefits.

It’s a added bonus to my gut I didn’t experience a lot of bloating while drinking it so, I recommend R’ Koso.

This product caught my attention since I am Chinese and never come across this interesting product before! The variety of 100 different fruits, vegetables,seaweeds, mushrooms fermented with both probiotics and prebiotics captivated me. This concoction is purposefully made for cleansing and fasting, of which I do. I do intermittent fasting and utilize this to break my fast, especially on the longer 2-3 day fasts. Customer service chat support answered my queries honestly and the best he could, especially when I asked for certificate of authenticity for organic certification. Because it was made in Japan, he only can verify verbally it is natural, but could not prove to me it was pesticides, herbicides free. I was glad that I did not have to pay further duties and taxes when it arrived from USA into Canada through UPS courier services. The Koso(fermented drink) arrived in regular bubble wrapped package and inside was a plain box. When I read the instructions I panicked a bit because I didn’t have the proper measuring utensils to pour my it 30 millimeters into half a cup dosage. To my delight, after opening the box containing the bottle of koso, on the cap was a plastic measuring cup hung upside over it. It had the exact 30 mil required to make the drink. For those of you when have been to Asian or Chinese hot pot restaurants, where you dip veggies, meat, seafood, located in the middle of the table in a heated stew pot. They often serve what is called a sweetened plum juice drink. This koso tastes very similar to this! This drink did curb my hunger pangs, although for me, half a cup wasn’t enough and I drank a full cup with 2 shots of 30 millimeters instead. It is sweet, sugary but you need to mix or swirl the thick syrup like mixture using cold water, room temperature or filtered water. I didn’t use hot water since it might destroy the nutrients. Koso is a food based supplement, used for cleansing and not a meal replacement. I enjoyed it and it did not affect my fasting diet. I have been using it for two weeks so far after my long fasting periods. I am already down to half way through the bottle and if you follow their cleanse schedule this bottle will not last more than a month. There is an option to subscribe every 14/30/60/90 days at 25% discount if you want it as part of your cleanse regimen.
