Reply To: So glad to find this site for D3 advice. My husband and I are 55 and 57 yo and are each taking 40,000 IU D3, 1,200 mcg K2 mk7 and 800 mg of magnesium DAILY and have done so for about 3 weeks. So far very positive results. My question is this; is our daily 1,200 mcg of K2 mk7 and 800 mg magnesium adequate to compensate for the high D3? Or should we take more of the K2 and magnesium? (I'm aware of the need to add K2 to help distribute the calcium to our bones rather than our blood/soft tissues.) Thank you for your response.
