Abstract
Vitamin D promotes the production of vitamin K-dependent proteins, which require vitamin K for carboxylation in order to function properly. The purpose of this review is to summarize available evidence of the synergistic interplay between vitamins D and K on bone and cardiovascular health. Few intervention trials studied vitamin D and K supplementation with cardiovascular-related outcomes.
Current evidence supports the notion that joint supplementation of vitamins D and K might be more effective than the consumption of either alone for bone and cardiovascular health.
What Are Vitamins D And K?
Often called the “sunshine vitamin,” vitamin D is abundant in fatty fish and fish oil, but it’s also produced by your skin when it’s exposed to sunlight. A vitamin D deficiency may cause bone loss.
Vitamin K is found in leafy greens, fermented legumes and vegetables, as well as in some fatty, animal-sourced foods, such as egg yolk, liver and cheese.

There’s also some evidence vitamin K may help keep bones healthy.
Good Sources Of Vitamin K
Adults need approximately 1 microgram a day of vitamin K for each kilogram of their body weight.
The word microgram is sometimes written with the Greek symbol μ followed by the letter g (μg). Any vitamin K your body does not need immediately is stored in the liver for future use, so you do not need it in your diet every day. Taking 1mg or less of vitamin K supplements a day is unlikely to cause any harm.
