Review: Tastes like mochi to me - It tastes like mochi to me and I like taking it in water as it tastes good. Mixes fairly well. I give it a good stir and let it sit for a little bit so it dissolves more, but I will just eat the clumps if there are some still. If you like mochi, you should like it. I'm trying it because I am having problems with bloating reacting to fiber because of digestive issues. I can't say whether it's good for my usage yet, but I don't think it's causing me to bloat.
Review: Give it some time and be consistent - Okay, I have apparently been dealing with pretty serious gut issues for many years. I chalked it up to stress, some weight gain, etc. My wife suffered from "leaky gut" (I know; sounds fake...just google it..it's REAL) and used a similar product from a local healthfood store to incredible effect. I was doubtful this would do anything, but I started taking it. Immediately, I noticed some GI discomfort, some gas/bloating. This was partially mitigated by increasing fiber intake (also found here on desertcart; Naturebell's 3-in-1 2000mg stuff). But there's no sugar-coating it; I had some bubble-gut for a few days. BUUUT. Afterwards, my life changed. Seriously. I realized that I had some serious, chronic gut inflammation/irritation. For decades. I was only absorbing a portion of the food and vitamins I ate. I can't recommend this enough. Your gut takes time to regulate. This has changed my life.

### ⭐⭐⭐⭐⭐ Tastes like mochi to me

### ⭐⭐⭐⭐⭐ Give it some time and be consistent
*by T***Y on August 28, 2026*

Okay, I have apparently been dealing with pretty serious gut issues for many years. I chalked it up to stress, some weight gain, etc. My wife suffered from "leaky gut" (I know; sounds fake...just google it..it's REAL) and used a similar product from a local healthfood store to incredible effect.

### ⭐⭐⭐⭐ Relatively good buy for Amazon. Recommend Subscribe & Save for at least a 3-month period (IMO).
*by D***D on July 21, 2025*

Good product, however, not really sure if it is doing anything. It's not one of those products where something happens right away, at least in my experience. This product, overall, is relatively high priced in the supplement area. It cold be one to try for a 3-month period with probiotics to find out if someone feels better in different ways, as in elimination, gas, bloating, etc. I like to try trendy products backed by science, like this version, to see if it helps with overall health. There are other brands with larger containers, although this one was a relatively good buy for the price per ounce. It averages 30 servings, so a good trial, IMO, would be a repeat purchase. One may try the Subscribe & Save, to save more, about $0.10 per ounce, and cancel after the 3 months if nothing has improved.
