What vitamins have a higher potential for causing toxicity and why?
Fat soluble vitamins can be stored in the adipose tissue instead of excreted if in excess. As a result, vitamins A, D, E, and K can cause toxicity if patients take too much (in this order of incidence as well).
- Hypervitamintosis A can result in ataxia, hepatotoxicity, visual impairments, and orange skin.
- Hypervitamintosis D can result in hyperphosphatemia and hypercalcemia.
- Hypervitamintosis E can block vitamin K absorption and leads to easy bleeding and bruising
- Hypervitamintosis K is very rare and really only seen in infants receiving newborn injections after birth.
