Minerals come from water and from the earth. Plants and animals absorb them to get nutrients.
Your health care professional may suggest taking extra vitamins or minerals if you have health problems such as osteoporosis
You also need more vitamins and minerals at certain times in your life, such as pregnancy, breastfeeding, or if following a vegan or vegetarian diet or have an allergy to a major food group such as dairy.
You can overdose on vitamins and minerals and should follow the recommended daily doses or those recommended by a health care professional.
If you are taking prescription medicine check with your doctor before commencing vitamin and mineral supplementation as these may interact with your prescription medicine or prevent correct absorption.
