Nutrition messages can be very confusing. One minute you’re advised to eat plenty of fruit and vegetables to get your essential vitamins and minerals and next, you’re told that too many vitamins might actually be harmful.
But wait! There’s no need to panic and it doesn’t mean that you have to throw out your week’s supply of veggies. However, if you take vitamin supplements, you should be aware that very high intakes of some vitamins could be potentially harmful.
If you eat a healthy, balanced diet then there is no need for you to take supplements. There are, of course, some instances where supplement use is advisable, such as during pregnancy or if you follow a vegan diet but many people take them in addition to a balanced diet. In extreme cases, they could actually be doing themselves more harm than good.
Here are some of the effects that excessive intakes of some vitamins can have:
Too much vitamin A can cause nausea, headaches, blurred vision, an orange skin colour and possibly even liver damage.
Over-consumption of vitamin D can lead to loss of appetite, weakness and excessive thirst and the other fat-soluble vitamins E and K can interfere with some blood clotting medications.
We all know how good vitamin C can be for us but did you know that too much of it can cause nausea, diarrhoea, and in severe cases, it can form kidney stones? And high levels of vitamin B6 can cause nerve damage.
So next time you’re thinking of stocking up on vitamins, ask yourself do you really need them. It may be a good idea to keep some in the cupboard for days when you are feeling rundown or haven’t eaten properly, but only buy those that have amounts no greater than the recommended daily amount.
As long as your diet remains balanced and varied, you will obtain all your vitamins from your food and will probably have no need to take supplements.
