I am a sixteen years old school girl. I want to have the magnesium caps along with my pills for the cold and cough. Would you recommend such an intake of the pills? I hope the combination is not harmful to me in any ways. What do you have to say about it? Another thing I need to ask you is that what according to you is the right dosage for the magnesium caps when I am taking them with my pills for the cold and cough?
