Tag: Vitamin k2 dosage

While no official Recommended Dietary Allowance (RDA) has been established for vitamin K2 specifically, many health experts and studies suggest a daily intake ranging from 100 to 300 micrograms for adults to support optimal bone and cardiovascular health. This fat-soluble vitamin plays a crucial role beyond just blood clotting, impacting calcium metabolism significantly.

In rare instances, taking vitamin K2 supplements can lead to mild digestive issues such as an upset stomach or diarrhea. While typically well-tolerated, some individuals may experience gastrointestinal discomfort, particularly when starting a new supplement regimen or taking higher doses.

Observational studies, like the Rotterdam Study, have shown a significant association between higher vitamin K2 intake and a reduced risk of coronary heart disease and mortality from heart disease. However, the ideal amount for optimal heart health remains a subject of ongoing research and varies depending on individual factors.

Studies indicate that consistent vitamin K2 supplementation, particularly the MK-7 form, for 2 to 3 years can significantly improve bone and cardiovascular health. The optimal duration for how long should we take vitamin K2 depends on individual health goals, dietary intake, and overall health status.

Observational studies show that higher dietary intake of vitamin K2 is associated with a 50% reduced risk of death from cardiovascular disease related to hardened arteries. However, the notion that a specific dose of K2 can 'clear' existing arterial plaque requires a closer look at the available research.
