insights Analysis
Solaray Vitamin K-2 Menaquinone-7 50 mcg delivers Vitamin K2 in its preferred MK-7 form, derived from chickpea, indicating a natural source. While MK-7 is praised by nutritionists for its longer half-life and superior systemic activity compared to MK-4, the 50 mcg dosage is on the lower side for adult therapeutic or even optimal maintenance doses, which typically start from 90 mcg upwards. For maximal benefit in bone and cardiovascular health, Vitamin K2 works synergistically with Vitamin D, which is absent in this formulation. The product is a basic, single-ingredient K2 supplement, and its moderate price per serving doesn't quite justify the lower dosage given the availability of higher-dosed alternatives.
- Contains Menaquinone-7 (MK-7), the most preferred form of Vitamin K2 for systemic benefits.
- Derived from a natural source (chickpea).
- The 50 mcg dosage of MK-7 is relatively low for achieving significant bone and cardiovascular health benefits in adults.
- Does not include Vitamin D3, which is essential for optimal K2 synergy in calcium metabolism.
- Less potent and comprehensive compared to higher-dosed MK-7 products or D3+K2 combinations.

Vitamin K 60
It features the desirable MK-7 form of Vitamin K2, but the 50 mcg dose places it at the lower end in terms of potency within the Vitamin K supplement category.
Goals
While MK-7 supports bone health, the 50 mcg dosage is insufficient for robust adult benefits, and the absence of Vitamin D limits its capacity to properly utilize calcium for bone density.
The low MK-7 dose provides only a foundational contribution to heart health and arterial calcification prevention, falling short of more impactful dosages or combined formulas.
Its ability to offer comprehensive cardiovascular support is hampered by the conservative MK-7 dose and the lack of essential co-factors like Vitamin D.
