Overview

Vitamin D3 at 1,000 IU and K2 at 45 mcg are well below safe upper limits (4,000 IU for D3, no established upper limit for K2), minimizing hypercalcemia risk.
Potential interactions with anticoagulants like warfarin due to Vitamin K2's role in blood clotting; consult physician if on such medications.
Generally safe for healthy adults; no major side effects reported at these dosages, but monitor calcium levels with long-term use.
Not recommended for pregnant or nursing women without medical advice; suitable for children only under supervision due to varying needs.
Allergen-free formulation: no wheat, gluten, soy, milk, egg, fish, shellfish, tree nuts, or sesame; low contamination risk from GMP manufacturing.
