When we think of vitamins, we usually think of deficiency as our primary concern. We’re constantly warned about the risks and symptoms of not eating enough of the nutrients we need to grow and stay healthy. But what if you overdose on vitamins?
It’s a scenario we rarely think about, yet it’s pretty accurate. If you take a daily multivitamins, as well as high-strength boosters of some supplements – such as a vitamin D spray – and eat a nutritious, balanced diet rich in fortified foods, you may be overdoing it on the vitamin front without realizing it.
Unfortunately, taking alot of vitamins and minerals can have the same adverse effects as taking too few. You might not even be aware you’re at risk because the consequences are so mild.
What happens if you consume a huge amount of vitamins?
Contrary to popular belief, getting too many vitamins from unfortified foods is nearly impossible. For example, because bananas contain a lot of potassium, it’s been suggested that eating a lot of them is terrible for your health.
To acquire the recommended daily amount of 3,500mg, you’d have to consume more than seven bananas a day – and more than 42 bananas in a short period to feel sick from a dietary overdose of the mineral.
‘In general, people assume that vitamins are safe and that, even if they don’t provide any benefits, they are unlikely to cause harm,’ adds Dr. Lee. ‘Taking high doses of vitamins A, E, D, C, and folic acid did not always help prevent disease, and in certain instances could be hazardous,’ she says, citing a scientific analysis of high-quality randomized controlled trials on the topic.
