Please can anyone advise on the vitamins I’m taking? I am have found myself adding a new supplement to suit a variety of ailments over the last year. I take vItamin D and calcium (had a severe deficiency a few years’ ago and was advised to take them by the GP); Agnus Castus for PMT; vitamin B and magnesium (can’t remember why, but probably for tiredness and being generally miserable). I went to the GP yesterday as I’ve been having pains in my right kidney area. She asked about my stomach and bowel and I realised that I’ve had recurring constipation and stomach aches for about a month. I wondered if they could be attributable to the supplements. I’m 47 and feel peri menopausal, but this hasn’t been confirmed formally. I’m booked in for blood tests next week (cholesterol, thyroid, kidney function) but any tips before then would be really appreciated - happy to be told where I’ve gone wrong. Thanks for any help and advice.
