Analysis

Natural Factors Vitamin K2 100 mcg is a well-regarded supplement, evident from its high review count. The use of K2 in the Menaquinone-7 (MK-7) form, specifically from Natto, is highly desirable as MK-7 has a longer half-life and superior bioavailability compared to other forms like MK-4 or K1, allowing for consistent blood levels and efficient utilization in the body. The 100mcg dosage is considered effective for general bone and cardiovascular maintenance. While a solid choice for K2 alone, its utility for bone and heart health goals is enhanced significantly when paired with Vitamin D3, which this product does not include.

Pros
  • Contains Vitamin K2 in the highly bioavailable Menaquinone-7 (MK-7) form, derived from Natto.
  • Provides an optimal 100mcg dosage for daily maintenance and targeted health goals.
  • Offers a good price per serving, providing solid value for a quality MK-7 product.
  • High review count suggests strong consumer satisfaction and product reliability.
Cons
  • Does not include Vitamin D3, missing the synergistic benefits for bone and cardiovascular health.
  • As a standalone K2 product, it requires users to source Vitamin D3 separately for comprehensive benefits.

Vitamin K 85.0
This product scores highly within the Vitamin K collection due to its optimal dose of the superior MK-7 form of K2, which is widely recognized for its efficacy and bioavailability compared to other Vitamin K forms. It's a high-quality standalone K2 supplement.
Goals
Bone Health 80.0
Vitamin K2 is essential for activating osteocalcin, a protein that integrates calcium into bone matrix. The MK-7 form at 100mcg is effective for directing calcium to bones, thus supporting bone density and strength. However, the absence of Vitamin D3, which aids calcium absorption, means it's not a complete solution for optimal bone health alone.
Heart Health 78.0
K2 helps activate MGP (Matrix Gla Protein), which prevents calcium from depositing in arteries, thereby supporting arterial flexibility and heart health. The MK-7 form is particularly effective for systemic cardiovascular benefits. While effective, the lack of D3 limits its full potential as D3 also plays a role in cardiovascular function.
Cardiovascular Support 78.0
The 100mcg of MK-7 is a beneficial dose for activating proteins that prevent arterial calcification, a key factor in maintaining healthy arteries and supporting overall cardiovascular system function. Its effectiveness is well-supported by research in this area, though synergistic nutrients like Vitamin D3 would further enhance its supportive role.
