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 KOSO

I’ve had a few types of KOSO and I love the taste of this one. I drink it daily as a semi sweet treat, but love the benefits. I started with one bottle and then purchased the 12 pack in bulk to share with family. Buy in bulk! You won’t regret it!
