Trial Pack - Japanese Postbiotic Drink (30ml/1oz × 5 bottles) - R's KOSO -

Amazing probiotic!

I have been using Koso for about a year, and love it! I look forward to drinking it every morning! Great start to my day!

Effective and delicious

Highly effective! Tastes great when mixed with sparkling water, making it easy to enjoy daily. I noticed weight loss within the first week, especially when following the recommended guidelines. Thank you!

Delivery/order issues

There were issues/problems with my order but I’m glad they were able to fix it, very calm and professional.. definitely will order again..

Easy to take a sip in the morning and it seems to be working very well.

Great product!

This is a great product! It tastes delicious when mixed with sparkling water. Following the suggested guidelines in the packaging, my wife and I lost a few pounds within a week. The customer service is also efficient and friendly. We’re beyond satisfied with the entire experience. Thank you!

Koso

Love this product. It tastes great and helps fasting. Makes me feel great

Works well, does not taste great

This works a treat, but the taste is off putting. It is far from the worst thing I have tasted, but it is bad enough that I have to force it down each morning and chase it with something stronger flavoured.

That said, I can already tell that it is working. Overall, less bloating and gas buildup and even there are smoother BMs since starting.

Gut Soothing

R’s KOSO is so soothing for your gut. Magical probiotics ♥️

Great results

Amazing quality

Next do
Order can I get the normal bottle?

Amazing stuff!

After an amazing trip to Italy, I felt I wanted to come home and clean out my gut and give it a refresh. Koso did exactly that. After two weeks my gut health seems vastly improved. Awesome product it really works!

Mini bottles

The product is great, I have lots of energy and weight loss.

It's working

I bought for my husband and luckily he enjoyed it every morning with hot water with honey, it reduce the belly fats slightly and without any side effects.
