I never received my order

delicious and nutritious

I drink R’s Koso mixed with sparkling mineral water every morning. What a great way to start the day!

KOSOtastic!

I have really enjoyed this product! I like the way it tastes and how it makes me feel! So happy I purchased this product!

Can't wait to try it! I am ready for that smooth, yet sweet plum taste!!

I love it-- R's KOSO Lower Sugar

This is my first time trying R’s KOSO Lower Sugar. The sweetness was right for me. The taste is great (the smell is very similar to Kim Chi but with some sweetness and no sourness). I am doing the Breakfast Cleansing Program. I will need more time to evaluate the long term health benefits. But I could notice less gas after my meals

R's KOSO Lower Sugar - Japanese Postbiotic Drink (280ml / 9.5oz)×2 bottles

I was surprised at how amazing this tastes! It is a real treat.

gut + glow

really enjoying this for my health. noticed my stomach is flat now & my face is glowing. vibrancy from inside out

Love it!

Have been drinking Koso for more than 2 years now and it is now a staple in my daily routine. I drink it in the morning right after I wake up and before or after meals depending on how I feel that day. I sometimes use it as a half day cleanse and always feel lighter and less bloated. Tastes like a yummy plum juice and I can't imagine not having it in my routine. It has helped me so much with digestion & bloating.

The Best!

It is the best remedy to bloating. No more bloating! Wish the price is a bit lower..,

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 ♥️
