Everyone knows supplements can be expensive but they can be dangerous also.
Vitamins break down into water soluble and fat-soluble. Typically there is more concern with the fat soluble vitamins (A,D, E & K) because they are not excreted from your body. The excess of water soluble vitamins like B and C will get flushed out of the body but with the fat soluble vitamins the excess is retained in your body.
That can get to be a problem if you are taking excessive amounts of vitamin D for example. There is no official figure for how much vitamin D you need, but it should be somewhere in the vicinity of 5 mcg – 10 mcg at the most. For those who don’t get exposure to sunlight, you can get vitamin D in cod-liver oil but be careful not to consume more than 20mcg’s. Vitamin D is toxic at very low levels, so having too much in your system can be dangerous.
There are very well documented cases of vitamin overdoses and the consequences of taking too much of one vitamin or mineral. You must be careful. Most will tell you how much to take on the label.
If you intend to eat that day as well as take the supplements, you could be over-dosing yourself on that particular vitamin or mineral. I can become difficult to know if you are getting the right amount of nutrients.
Talk to your doctor about the correct supplements for you.
