Review: Best For the Gut health! - Hands down one of the best products but the only bad thing is it keep on getting out of stock which is kind of frustrating.
Review: Great for Digestive Health and Energy Levels - I’ve been using this probiotic product for some time, originally in Hong Kong and now continuing here in the UK. I chose it because it’s developed by the Chinese University of Hong Kong, a brand I trust for its scientific backing. Since starting this formula, I’ve noticed several significant improvements. My sleep quality has gotten better, I feel more energetic, and most importantly, my digestive health has improved dramatically. I now have a regular toilet routine every day, and the bloating and belly grumbling issues I used to experience have disappeared. I highly recommend this probiotic for anyone looking to improve their gut health and energy levels!

### ⭐⭐⭐⭐ Seems to be OK, but difficult to know.
*by B***I on 9 January 2024*

G-NiiB Immunity+ microbiome Balance Formula. It's difficult to review vitamin's/Minerals etc as unless you have blood tests etc to show the difference, how do you know they are working? I've been taking these for a week now, on its own in a glass of room temperature water, the fine white powder dissolves easily and becomes almost completely clear, on drinking there is no taste at all, and no grittiness either. Does it work? I think this sort of thing needs to be taken for a lot longer to notice any real improvements, but I can say I have had no negative side effects which is a good point at least. Unfortunately at almost £2 a day this is something I couldn't afford every month but it will be interesting see how it goes in a few more weeks time.
