Many people also tend to have lower , mayhap insufficient storey of sealed nutrient , such asvitamin D , so supplement on a fount - by - compositor’s case basis could facilitate fill these gaps . But right now , about 52 % of Americans are gauge to take supplements on a regular basis , while about a third take a multivitamin .
