Ancient Nutrients Vitamin D combines Vitamin D (implied from the product name) with a substantial dose of Vitamin K2 (Menaquinone-7) at 90mcg. The MK-7 form is highly regarded for its effectiveness in directing calcium to bones and away from arteries, making it excellent for bone and cardiovascular health. The 'Ancient Nutrients' brand often implies a focus on whole-food or fermented ingredients, which can appeal to consumers seeking more natural or holistic supplement forms. The 90mcg MK-7 dose is higher than many standard daily supplements, suggesting a more robust approach to K2 supplementation, which is beneficial for those aiming for more significant support. While a solid product, its higher price per serving may be a factor for budget-conscious consumers, and its lower review count compared to market leaders might indicate a more niche market or newer presence.
