## Description

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

Review: Taste good - It tasted great and I had no reactions. I can not tell if it worked but I would use it again.
Review: This works! - This works, but you need to be near a bathroom when lightening strikes. The taste is nice. I used cold filtered water. I suggest that if you do not work from home that you use it during the weekend. I used a tablespoon with 8 oz of water. I noticed a difference in my skin and my thoughts are clearer. I've been using this for 2 weeks. I will buy this again.

### ⭐⭐⭐⭐⭐ Taste good

### ⭐⭐⭐⭐⭐ This works!
*by D***S on December 12, 2025*

This works, but you need to be near a bathroom when lightening strikes. The taste is nice. I used cold filtered water. I suggest that if you do not work from home that you use it during the weekend. I used a tablespoon with 8 oz of water. I noticed a difference in my skin and my thoughts are clearer. I've been using this for 2 weeks. I will buy this again.

### ⭐⭐⭐⭐ Too expensive and tastes so so
*by E***A on March 11, 2023*

I did a week cleanse so I purchased those small bottles. I drank one a day in the morning. The taste was bearable but not great. I know that it's not a smoothie, but the taste is not the best. It did help with my cleanse though, and combined with some healthy food, I feel that it helped me feel better and lighter. I would probably buy more if it was not so expensive. The large bottle is $100 unfortunately. I know that it comes from Japan, but really? $100? It is liquid gold? I will not purchase again.
