I would advise you that the dosage of
vitamin D3 and
B12 for a child should be based on specific needs, which can be determined through a blood test and an evaluation of symptoms. Vitamin D3 is typically supplemented to improve bone health, while B12 is essential for neurological development. However, improper dosing can have side effects, so it’s crucial to consult a pediatrician for accurate recommendations based on your child's health condition, particularly since she has mentioned neck complaints.
