Certain forms of vitamin A pose a higher risk of toxicity, such as retinol, retinyl acetate, and retinyl palmitate. Beta-carotene and carotenoids are less risky.Vitamin D: Taking too much vitamin D can raise the calcium levels in the body too high, causing pain, dehydration, nausea, vomiting, kidney stones, or even kidney failure and heart disease.
