How much vitamin D should I take?

Gary Brecka recommends taking a minimum of 5000 international units (IUs) of vitamin D3 daily, ideally with 120 micrograms of vitamin K2. This combination helps ensure that calcium is properly absorbed and deposited into bones rather than arterial walls. He stresses the importance of maintaining vitamin D3 levels between 60 and 80 nanograms per deciliter for optimal health benefits, which include improved mood, better immune function, and reduced risk of various diseases 1.

It's also advisable to check your vitamin D3 levels during routine blood tests to ensure they fall within this optimal range 1.
