More and more recent studies come to the same solution – buying dietary supplements isn’t worth the cost. Although doctors usually advise their patients that supplements aren’t worth taking, unless they are truly necessary, the most common mode of thinking is something like “okay, maybe I don’t need them, but hey, they can’t hurt me.”
Well, this mode of thinking may just be wrong. The newest researches show that supplements drive more than 20,000 people to the emergency room each year, and one tenth of that number ends in hospitalizations. A study found in the New England Journal of Medicine has investigated the medical records of the past decade and the results show that around 23k American citizens end up in hospital due to dietary supplements (including herbals, amino acids, vitamins, minerals, etc.).
However, according to scientists, this does not necessarily imply that supplements are hazardous. The main issue with supplements is that, unlike the prescribed medicaments, they are not always appropriately tested and some of them don’t have the FDA approval. In addition, when taking supplements without doctor’s supervision, they may be in conflict with your regular medication.
So, strictly speaking, supplements are not hazardous, but they should be taken with proper caution and in consultation with your doctor. If they are not necessary, for some reason, it may be better to avoid using them.
