A convenient liquid D3 and K2 (MK-4) supplement, but its low dosages and use of MK-4 at a suboptimal level limit its effectiveness for comprehensive adult bone and heart health.
Dose: D:125mcg, K:100mcg, Quantity: 60
Seeking Health Vitamin D3 + K2 Drops provides a liquid formulation containing 500 IU of Vitamin D3 and 50 mcg of Vitamin K2 as MK-4. While the liquid form offers absorption advantages and dosage flexibility, the dosages of both vitamins are quite conservative for typical adult requirements for bone and cardiovascular health. Nutritionists often recommend higher D3 (e.g., 2000-5000 IU) and K2 (e.g., 90-300 mcg MK-7) for therapeutic or maintenance effects. Furthermore, the use of MK-4 at 50 mcg is generally considered less effective for systemic benefits compared to MK-7 due to its shorter half-life and the need for higher doses for therapeutic effects. The price per serving is relatively high for the low potency offered.
- Liquid drop form allows for flexible and potentially better absorption.
- Combines Vitamin D3 and K2, which are synergistic.
- Low dosages of both Vitamin D3 (500 IU) and K2 (MK-4: 50 mcg) for adult needs.
- Uses MK-4 form of K2, which at this low dose is generally less effective than MK-7 for systemic benefits.
- Relatively high price per serving given the low potency.

Categories
Vitamin K 55.0
It contains K2 as MK-4, but at a very low dose, making it a less competitive option within the Vitamin K collection compared to products with higher MK-7 concentrations or more comprehensive K forms.
Goals
Bone Health 50.0
The very low doses of D3 and K2, combined with the less potent MK-4 form, provide only minimal support for adult bone health compared to more robust formulations.
Heart Health 50.0
Its contribution to heart health is limited by the low dosages of both key vitamins, and the MK-4's reduced systemic impact at this concentration for arterial health.
Cardiovascular Support 50.0
The minimal D3 and K2 (MK-4) content means it offers insufficient comprehensive cardiovascular support for adults seeking targeted benefits.
