Vitamins D3 and K2

Taking vitamin D3 alone is effective for raising levels, but combining it with K2 and ensuring adequate magnesium enhances calcium absorption into bones. K2, often found in fermented foods and egg yolks, works synergistically with D3 to prevent excess calcium in the bloodstream, which can lead to health issues. While leafy greens provide vitamin K1, they do not supply K2, highlighting the importance of dietary sources or supplements for optimal health.
