This is a convenient one-dropper D3/K2 formula, but its 10,000 IU daily vitamin D dose is high for routine unsupervised use.

Scoring criteria

Quantity
100 / 100
One daily serving provides ample vitamin D3 and a meaningful 120 mcg amount of vitamin K2, so the formula is quantitatively sufficient despite the excessive vitamin D level.
Form
75 / 100
Vitamin D3 and the MK-4/MK-7 vitamin K2 forms are clearly identified in a liquid dropper, but the label does not establish a specific oil vehicle or a comparative delivery advantage.
Convenience
100 / 100
The label directs one 1 ml dropper daily, and the two-pack contains two 30-serving containers.
Label accuracy
75 / 100
The photographed panel is broadly internally consistent, but medium-confidence image reading leaves ordinary uncertainty about complete label accuracy.
Formula balance
75 / 100
The D3 and K2 combination is nutritionally coherent, but the formula offers no demonstrated added balance benefit and the high vitamin D exposure remains a separate safety concern.
Purity
75 / 100
The label lists no obvious problematic additives, while GMP, organic, and non-GMO claims lack named certification or test evidence.
Cofactors
0 / 100
The listed omega-3 amount is not established as a meaningful cofactor for the stated D3/K2 role, and vitamin K2 is already treated as a principal nutrient.
