Overview
•Vitamin D3 at 1,000 IU is well within safe daily limits (up to 4,000 IU for adults) with low risk of hypercalcemia in healthy individuals.
•Vitamin K2 (MK-7) at 45 mcg poses minimal side effects but may interact with anticoagulants like warfarin, requiring medical consultation.
•Product is suitable for adults; contraindicated in pregnancy/nursing without physician approval due to potential effects on blood clotting and calcium levels.
