Vitamin D Ultra 10K is our highest potency vitamin D product, providing 10,000 IU of vitamin D per serving, and is intended for situations where more aggressive vitamin D repletion is recommended. 


Vitamin D Ultra 10K also includes vitamin K as both K1 and the MK-7 form of K2. Both of these forms of vitamin K are important to our health: vitamin K1 (the naturally occurring form of vitamin K in vegetables) and vitamin K2 as MK-7, which is a product of soy fermentation (free of soy allergens) and has the special property of metabolizing slowly throughout the day.


Vitamins D and K are essential for optimal bone and arterial health and for maintaining the immune system in proper balance.



Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys. Deficiency in either of these nutrients is reported to be associated with various disorders, such as skeletal deformities, cardiovascular diseases, and metabolic syndrome. It is therefore essential to ensure that the recommended amount of magnesium is consumed to obtain the optimal benefits of vitamin D. 


So Be Sure that you are Taking the Complete Multi with Copper with this as it has the daily required optimum dose of Magnesium.
