So my recommendation would be: if you are getting enough calcium in your diet (via dairy and other calcium-rich food), it is best to avoid supplements.
Ingcebiso yam kukuba ukuba ngaba ufumana icalcium eyaneleyo ekutyeni kwakho (kwiimveliso zobisi nakokunye ukutya okunecalcium), kuya kukunceda ukungazisebenzisi izongezo.
