Turkish doctor Professor Galip Eköklu warned that taking vitamins and nutritional supplements without medical advice may lead to health problems. Following a balanced diet and regular sleep are sufficient to maintain the strength of the immune system.
People who do not suffer from a specific disease or disorder related to the absorption of vitamins can get all the vitamins they need from foods while following a healthy diet. The most dangerous thing is to buy nutritional supplements online based on circulating rumours, without any medical advice, adds the Turkish doctor.
