It’s the only thing I’m doing differently lately. I’ve been taking probiotics for a while (a vitamin that I swallow every morning) and eating Kefir yogurt too. I hope I don’t jinx myself but my DH is unwell at the moment with a sore throat/cold type symptoms and I have been in contact with people who are unwell lately - usually I catch everything going, but so far I’ve not been unwell at all this season touch wood
I also take vitamin D3, B6 and magnesium.
