According to the National Institutes of Health, the recommended Adequate Intake (AI) for vitamin K varies by age and gender. These guidelines are based on median dietary intake observed in healthy individuals, as a true Recommended Dietary Allowance (RDA) has not been established for this fat-soluble nutrient.

Studies show that certain forms of Vitamin K2 can maintain significantly higher serum concentrations over a longer period compared to Vitamin K1. So, when it comes to the question, **'Is K1 or K2 more bioavailable?'**, the answer is crucial for understanding how to optimize your dietary nutrition.

While most people know vitamin K for its critical role in blood clotting, fewer realize it comprises two main forms, K1 and K2, each offering distinct and important health benefits beyond coagulation. These fat-soluble vitamins, though structurally similar, differ significantly in their dietary sources, absorption, and primary functions within the body.

While vitamin D is widely celebrated for its role in calcium absorption, a significant portion of the population may be unaware that this process is incomplete without its fat-soluble counterparts. This is precisely **why take vitamin D with K1 and K2** is a crucial consideration for a truly effective supplementation strategy.
