Overview
•At 1,000 IU vitamin D3 and 200 mcg K2 per serving, dosages are well within safe upper limits (4,000 IU for D3, 1,000 mcg for K2), minimizing hypercalcemia or other toxicity risks for healthy adults.
•Vitamin K2 (MK-4) interferes with anticoagulants like warfarin; avoid concurrent use and consult a physician if on blood-thinning medications.
•Generally safe for healthy adults with low interaction potential beyond anticoagulants; third-party tested for contaminants like heavy metals.
•Consult healthcare provider if pregnant, as safety data is limited; contraindicated in those with hypersensitivity to ingredients.
•No common allergens present; gluten-free, dairy-free, soy-free formulation suitable for most dietary needs.
•Long-term use at recommended doses supports bone and heart health without notable adverse effects in studies.
