Overview
DK Soft Gelatin Capsule contains Cholecalciferol (Vitamin D3) 400 IU, Vitamin K1 (Phylloquinone) 60 mcg, and Vitamin K2 (Menaquinone-7) 30 mcg, manufactured by Square Pharmaceuticals PLC. This combination provides complementary nutrients essential for calcium metabolism and bone health — Vitamin D3 enhances calcium absorption, while Vitamin K1 and K2 direct calcium to bones and away from soft tissues (arteries, kidneys).
Dosage and Administration
Adults: one capsule daily with a meal, or as prescribed. Best absorbed when taken with a fatty meal.
Interaction
Thiazide diuretics may increase hypercalcaemia risk with Vitamin D. Warfarin anticoagulant effect may be reduced by Vitamin K — monitor INR closely if starting or stopping this supplement.
Contraindications
Contraindicated in hypercalcaemia, hypervitaminosis D, conditions requiring strict anticoagulation with warfarin (Vitamin K may reduce warfarin efficacy), and known hypersensitivity to any component.
Side Effects
Generally well tolerated at recommended doses. Excessive Vitamin D intake may cause hypercalcaemia.
Pregnancy and Lactation
Vitamin D and K supplementation may be recommended during pregnancy; use at recommended doses only under physician guidance.
Precautions and Warnings
Patients on warfarin should inform their physician before taking this supplement, as Vitamin K may reduce anticoagulant effect and require INR monitoring and warfarin dose adjustment.
Storage Conditions
Store below 25°C in a cool, dry place, away from light and moisture.
Frequently Asked Questions
Why is Vitamin K combined with Vitamin D in this supplement?
Vitamin D increases calcium absorption but without sufficient Vitamin K, calcium can deposit in arteries (calcification) rather than bones; Vitamin K (especially K2) activates proteins that direct calcium to bones and teeth and away from soft tissues.
Can patients on blood thinners take this supplement?
Patients on warfarin should use caution — Vitamin K counteracts warfarin's anticoagulant effect; any supplement containing Vitamin K must be discussed with the prescribing physician and INR monitored closely.
