I'd like to boost my immune system, as I'm really struggling with a virus at the moment.
I currently work from home and don't mix much with other people. I do pilates/swimming a couple of times a week. I'm a post-menopausal woman.
I'm going to try to get outside during the day more regularly, and mix more with other people. I'm going to get better at drinking kefir. I'm going to pay for flu/COVID jabs privately.
What else can I try?
