Vitamin D3, vitamin K2, and magnesium are involved in a complex interplay inside your body.
Magnesium plays a key role in how your body uses vitamin D, while vitamin D levels can influence how magnesium is absorbed in the digestive system.
Meanwhile, vitamin K2 works in synergy with vitamin D to maintain calcium balance and regulate the deposition of calcium into bone tissue.
While magnesium supplements don’t have to be taken at the same time as vitamin D, it’s recommended to opt for a combined vitamin D3 and K2 when supplementing.
