“ People take these supplements to make sure they get enough essential nutrients and to maintain or improve their health. But not everyone needs to take supplements.”
“ Evidence does suggest that some supplements can enhance health in different ways. The most popular nutrient supplements are multivitamins, calcium and vitamins B, C and D.
