Vitamins
Vitamin supplements may be an undercover culprit in causing constipation. Constipation does not occur with every vitamin supplementation intake but is most common with people who take iron and calcium supplements. According to medical professionals, the iron and calcium supplements might act as blockers in the normal functioning of the digestive system. So, the people who need those supplements like anemic patients also use stool softeners along with these supplements to avoid constipation.
