More is not always better. Did you know that you can develop toxicities from things that seem ‘harmless’ including vitamins? Vitamins A,D,E & K are “fat-soluble” meaning that they are able to dissolve in fat. These can be stored in your body if you take in too much of them. “Water-soluble” vitamins are more easily eliminated by your body unless you have liver or kidney disease.
What vitamins should you be worried about?
The vitamins you should be most concerned about are Vitamins A, D and B6 (Pyroxidine).
Vitamin A: Upper Limit is 3gm/day Toxicity is: Headache, double vision, nausea/vomiting, vertigo, fatigue
Vitamin D: Upper Limit is 50 mcg/day (2000 intl units)/day Toxicity is: Anorexia, hypocalcaemia, soft-tissue calcification, kidney stones, and renal failure
Vitamin B6 (Pyridoxine): Doses greater than 50mg/day may cause severe sensory neuropathy
So, the next time you are choosing a multivitamin or taking a supplement you may want to take a second look at the content of these three vitamins.
