I have vitamim d deficiency which was less than 10 (75-110 was normal value) and rest of the values were normal for which the doctor precribed me D3 60k and i started feeling well after 3 weeks but after that i started feeling unwell again after which he prescribed me bio d3 plus which is also not working well. I feel lack of energy (brain fog, confused) also gastritis for which i was precribed antacid every morning and dry throat n mouth every day and muscle pain and joint pain for which doctors prescribed shine 10 which is medicine for anxiety. I wanted to ask can it be due to magnesium deficiency? Can i take a safer magnesium supplement for some week like calmag by amway magnesium citrate 200 to see if it makes me feel well perhaps. Please help.
