Vitamin D toxicity is rare and typically occurs only at sustained intakes above 10,000 IU daily without medical supervision. At 5,000 IU (125mcg), this product is within safe limits for most adults, but you should test your serum 25(OH)D levels periodically.

Vitamin D supplementation is generally recommended during pregnancy, but doses above 2,000 IU should be discussed with your OB-GYN. The American College of Obstetricians and Gynecologists recommends at least 600 IU daily for pregnant women.

Vitamin D can interact with certain medications including thiazide diuretics, corticosteroids, and weight-loss drugs like orlistat. Consult your healthcare provider if you take prescription medications.

Side effects are uncommon at recommended doses. Very high doses of vitamin D may cause nausea, constipation, or elevated calcium levels. Start at the recommended serving and monitor how you feel during the first two weeks.

Each bottle contains 360 servings. At one serving per day, this provides approximately 12 months of daily supplementation.
