Hi, I did a fair bit of research on the gut microbiome and found that supermarket probiotics are not necessarily the way to go and that naturally fermented foods such as kimchi, kefir and sauerkraut are way better for your gut as they deliver a more useful range of bacteria in a more gut friendly form. These are available in supermarkets but if you are game you could ferment your own and get a much better range of probiotics. I gave it a try but it's harder than it looks to get something that is safe to consume. I also found after trying a strict anti inflammatory diet for a while all my gut issues were gone. It was too restrictive to stay on long term but I've been on a very low gluten and little or no processed food diet for over 12 mths and my auto immune disease is finally at a level where I can enjoy life again.
