I don't believe I have a "gut health issue" vampirequeen but probably you were 'talking' to Fanny?
I have yogurt, kimchi home-made kefir, and prebiotic foods such as onions, wholegrains, legumes and nuts & seeds.
My interest really is in other health issues such as heart, brain, preventing Stroke, BP, inflammation etc.
Thanks Farzanah for info re your friend. It's not easy to see what you are "getting" for the fee. Obviously the study is ongoing.
I'm not keen to do things without a proper basis. I'm not easily influenced by no-evidence ideas.
Thanks everyone who has replied. I'm going to have to find out a bit more I think..
