Asif Ahmed 4 Of course, the vitamin is much needed, especially when lacking. But the supplement is not always good for health and may be bad for your child. If you take enough food (Not Processed or Man-Made) that contains the right energy, you do not need a supplement to cover the loss.However, if you still want to take it, do not take it 3/per day and take it every day. Keep a gap between taking supplements to create a balance in health and nothing can harm you all off a sudden.Thank you.
