Take a vitamin D supplement to correct the deficiency. When selecting a vitamin D supplement, you may want to choose D3 over D2. Both are easily absorbed by the body, but research suggests that vitamin D3 increases blood levels of the nutrient more and keeps those levels elevated longer than vitamin D2. You should take a vitamin D supplement as directed by your healthcare provider, likely every day or week, based on the formulation. Because vitamin D is a fat-soluble vitamin, it is best taken with meals or snacks containing fat, so the body can better absorb the nutrient. Side Effects of High Vitamin D Levels Vitamin D toxicity is unlikely to occur from diet or excess sun exposure since your body can control the amount of vitamin D it makes from the sun. In most cases, toxicity occurs due to the overuse of vitamin D supplements. The main side effect of vitamin D toxicity is a condition called hypercalcemia, in which too much calcium builds up in the blood, causing symptoms like:Nausea, vomitingConfusionMuscle weaknessDecreased appetiteGeneralized painExcessive thirst and urinationDehydrationKidney stones Extremely high vitamin D levels can cause more serious side effects, including irregular heartbeat, kidney failure, and death. Interactions Some medications may interact with Vitamin D supplements, decreasing their effectiveness or causing side effects. If you take any medications, check with your healthcare provider before taking a vitamin D supplement. Drugs that vitamin D supplements interact with include: Orlistat (Xenical, Alli): These weight-loss drugs may reduce the absorption of vitamin D.Statins: High-dose vitamin D supplements may decrease the effectiveness of cholesterol-lowering drugs like atorvastatin (Lipitor), lovastatin (Altoprev and Mevacor), and simvastatin (FloLipid and Zocor).Corticosteroids: Drugs like prednisone (Deltasone, Rayos, and Sterapred) may decrease levels of vitamin D in the blood.Diuretics: When taken with a vitamin D supplement, thiazide diuretics (like Hygroton, Lozol, and Microzide) can cause dangerously high levels of calcium in the blood. People with hyperparathyroidism, kidney disease, or hypercalcemia (high blood calcium) should also speak with their healthcare provider before taking a vitamin D supplement.
