I used to have a pretty robust immune system, rarely ill, but over the last year it's gone to shit. I had flu in February, covid in March (which wasn't as bad as the flu), not too bad over the summer, then got a heavy cold around 3 weeks ago and was barely over that (still a lot of catarrh) when I came down with flu at the end of last week and still have a heavy cold but feel marginally better. I was due the flu vaccine a few weeks ago but cancelled because of the cold and hoped I'd get to half term when I could have the flu jab. I work with children from many different schools across my county which doesn't help. I work long hours, from 9am sometimes until around 8.30pm and don't always get as much fresh air or exercise as I need. I think I eat a pretty healthy, varied diet with fresh fruit and veg.
At the moment I'm taking prescribed vitamin D/calcium and menopace (currently the night time one as that's all they had last time).
Any recommendations for multi-vitamin/mineral supplements or tonics? I'm trying to reorganise my working hours so that I have more time for exercise and getting out into nature, but it's taking time and I'm so fed up of feeling so run down.
