It seems that everybody is jumping on the supplement craze these days. Taking supplements can improve overall health and help balance our bodies when it seems they are out of whack. However, it is possible to take it too far. Many people try to do what is best for their health, but if you take too many supplements, there can be consequences. The overconsumption and misunderstanding of how and when to take too many supplements does more harm than good. We will go over common supplements and what happens if you take too much. And if you do decide to take supplements, make sure you are well informed. Always consult a healthcare provider. If you are careless, some supplement overuse can even be life threatening.


Too Many Supplements Are Taken Without Research Or Medical Advice

While it’s a good idea to be proactive for your own health, it’s not a good idea to start taking too many supplements without valid reasons. With the rise of the internet, we experience more access to health information. This can be seen as both a positive and negative outcome. Information access is a powerful tool. However, access to a lot of information breeds information illiteracy. Influencers begin promoting a certain health trend or new supplement, and their followers will jump onboard without questioning.
