Hi Sir, My boy male 9 years 8 month old having lactic intolerance since 4 yrs, thin in structure underweight (24 Kg) and low height 4'3" only. Recently diagnosis with low vitamin d level (9 ng/ml), doctor prescribed vitamin d3 60KUI once weekly, and he started taking but after two weeks he started developing allergy and rashes so immediately I stopped the dose, now I am thinking to give him lower dose of vitamin d3 (1K UI) every day, should I give vitamin k2 supplement along with this? I also tried calcimax-p syrup which contains calcium 774 mg along with vitamin d3 200 UI dosage 10 ml per day, but that too develop allergy, please suggest me solution.
