Servings Per Container

90

Best Time to Take

With meals

Recommended Daily Intake

Adults: 600-800 IU/day (15-20 mcg); upper safe limit 4000 IU/day; deficiency correction doses up to 2000 IU/day are commonly used clinically

Upper Tolerable Limit

4000 IU/day (100 mcg) for adults; 1000-3000 IU/day for children depending on age

Absorption Enhancers

Dietary fat (increases micellar solubilization and lymphatic absorption); magnesium (cofactor for vitamin D activation); bile acids

Absorption Inhibitors

Orlistat (blocks fat absorption, reducing vitamin D uptake); cholestyramine and colestipol (bile acid sequestrants impair absorption); high-dose calcium supplements taken simultaneously may compete; mineral oil laxatives

Side Effects

Possible Side Effects

Generally well-tolerated at 1000 IU/day; excessive doses may cause hypercalcemia, nausea, vomiting, constipation, polyuria, polydipsia, weakness, and kidney stones

Upper Tolerable Limit

4000 IU/day (100 mcg) for adults; 1000-3000 IU/day for children depending on age

Safety & Warnings

Children Suitability

Consult a healthcare provider for appropriate dosing in children; adult formulation at 1000 IU may be suitable for children over 12 under medical guidance

Interactions

Medication Interactions

Thiazide diuretics (increase hypercalcemia risk); corticosteroids (reduce vitamin D efficacy); anticonvulsants such as phenytoin and phenobarbital (accelerate vitamin D catabolism); rifampicin (increases vitamin D metabolism); digoxin (hypercalcemia from excess D3 increases digoxin toxicity risk)

Supplement Interactions

High-dose calcium supplements combined with high-dose vitamin D may increase hypercalcemia risk; vitamin A at very high doses may antagonize vitamin D activity

Special Populations

Target Population

Adults with limited sun exposure, elderly individuals over 50, individuals with darker skin tones, people with malabsorption conditions, pregnant and breastfeeding women under medical supervision, individuals with confirmed vitamin D deficiency

Children Suitability

Consult a healthcare provider for appropriate dosing in children; adult formulation at 1000 IU may be suitable for children over 12 under medical guidance
