Analysis

Carlson Vitamin K2 MK-7 (Menaquinone-7) 45 mcg provides a focused dose of Vitamin K2 in the highly bioavailable Menaquinone-7 (MK-7) form. At 45mcg, it's suitable for daily maintenance of Vitamin K levels to support bone mineralization and cardiovascular health by helping to prevent arterial calcification. This is a good choice for individuals who already supplement with Vitamin D separately or prefer to control their D3 intake independently. Carlson is a well-established brand, often recommended by nutritionists and earning positive online reviews for its quality and purity. Its straightforward formulation and reasonable price make it a solid option for targeted K2 supplementation without additional ingredients.

Pros
  • Contains the highly bioavailable and long-acting MK-7 form of K2.
  • Excellent price per serving for an MK-7 product, offering great value.
  • From a reputable and long-standing brand known for quality and purity.
  • Simple formulation without unnecessary additives, suitable for those who prefer standalone supplements.
Cons
  • Does not include Vitamin D3, requiring separate supplementation for optimal synergistic benefits for bone health.
  • The 45mcg dose might be considered a maintenance dose and could be insufficient for higher therapeutic needs.
