The verdict
Clean label, clinical dose.
For baseline-coverage seekers.

Vitamin D3 at 5000 IU (125mcg) is above optimal. K2 is provided as both MK-4 (1000mcg) and MK-7 (100mcg at optimal), covering both fast-acting and long-acting forms. K1 at 1000mcg is generous. The D3+K2 synergy is perfectly executed. However, iodine at 1000mcg is near the upper limit (1100mcg) and may be too high for those with thyroid conditions.
