insights Analysis
Nutricost Vitamin K2 100 mcg provides Menaquinone-4 (MK-4) at an exceptionally low price per serving, making it highly accessible. However, similar to the NOW K-2 product with MK-4, this form of Vitamin K2 is typically effective for systemic health benefits at much higher, milligram-level dosages. At 100 mcg, its impact on bone density and arterial health is likely limited according to nutritionist recommendations. The large quantity (240 servings) offers good value if one wishes to consume MK-4, but it misses the critical synergistic component of Vitamin D3, which is vital for optimal calcium regulation and the full benefits of K2 for bone and cardiovascular health. Online reviews often praise its affordability.
- Very cost-effective with a low price per serving and a large quantity.
- Provides Vitamin K2 (MK-4) for those specifically seeking this form.
- The 100 mcg dose of MK-4 is considered low for achieving significant systemic bone and cardiovascular benefits.
- Lacks Vitamin D3, a crucial synergistic partner for K2 in calcium metabolism.
- Less potent and comprehensive compared to MK-7 forms or D3+K2 combinations.

Vitamin K 70
It offers an economical source of Vitamin K2 as MK-4 in high quantity, making it a good choice for those who prioritize value for this specific K2 form.
Goals
While MK-4 has a role in bone, the 100 mcg dose is generally insufficient for significant impact, and the absence of Vitamin D impedes optimal calcium integration into bones.
The low dose of MK-4 offers limited direct benefit for preventing arterial calcification, a key mechanism of K2 in supporting heart health.
Its contribution to cardiovascular support is minimal due to the suboptimal MK-4 dosage for broad effects and the lack of essential synergistic nutrients like Vitamin D.
