Vitamin D3
What It Is Used For
Vitamin D3 (cholecalciferol) helps the body absorb calcium for strong bones and muscles. It is used to prevent and treat vitamin D deficiency, rickets in children and soft bones (osteomalacia), and alongside calcium in osteoporosis.
How to Take It
Daily maintenance for adults is usually 1,000 to 2,000 IU. Doctors give higher weekly or monthly doses to treat a proven deficiency. Take it with a meal that has some fat for better absorption.
Who Should Not Take It
Do not take it if you have high calcium in the blood, too much vitamin D already, or certain kidney stones.
Side Effects
Rare at normal doses. Too much over a long time can raise blood calcium and cause thirst, frequent urination, nausea, constipation, weakness and confusion.
Precautions
Do not take high doses for months without blood tests. Take extra care with kidney disease, sarcoidosis or a history of kidney stones.
Pregnancy and Breastfeeding
Safe at the usual recommended daily dose; higher doses only on a doctor's advice.
Interactions
Thiazide diuretics (such as Hydrochlorothiazide) with vitamin D can raise calcium. Orlistat and some seizure medicines can lower vitamin D levels. Use extra care with Digoxin.
Storage
Store below 30°C away from light, out of the reach of children.
