With research about vitamin D and cancer prevention in the news, many people are flocking to the stores and picking up just any old vitamin D supplement. While the idea and logic behind this is well-intentioned, unfortunately consumers aren’t always getting what they hoped for, and could be getting a whole lot more than they want.
Besides the question of bioavailability (how absorbable and useable the product is by your body), purity (many brands add a number of binders, fillers and preservatives), and form (beware of synthetic vitamin D2… Vitamin D3 is the only form of vitamin D your body can effectively use) there is an even greater risk factor – The Calcium Paradox.
The Calcium Paradox
- Vitamin D3 (the natural form of vitamin D) is required for the absorption of minerals in the body, including calcium.
- Vitamin K2 is required to direct these minerals to the right place in the body, preventing the inappropriate calcification of the soft tissues
A number of clinical trials have shown that the combination of vitamin K2 and vitamin D3 is more effective in preventing bone loss than either nutrient alone, and there is overwhelming evidence that the safety of vitamin D is dependent on adequate levels of vitamin K2:
— Without vitamin K2 to complement vitamin D3, calcium may go to the arteries instead of the bones.
Vitamin K2 has been linked to a decrease in atherosclerosis and coronary heart disease, due to its ability to decrease serum cholesterol and reduce cholesterol deposits and calcification in the aorta.
- Consider following the guidelines set out by the experts, and take 1000 IU of vitamin D3 daily.
- Make sure your supplement contains Vitamin D3, not the synthetic Vitamin D2
- Ensure that your supplement contains vitamin D’s important partner, Vitamin K2.
