It is now in the 90s (32C) in central Texas every day. Last summer saw 100+ (37C) every day for 90 days - 3 whole months. I would not dare get out in the sunlight for any extended time without slathering on sunscreen, which I do not trust. Hence, ... vitamin d3 supplement. 5000IU.

Its 95 here and feel temp on the news said 100 here in Florida. Wish I could say I was avoiding it but was at the beach a few hours today more than I should,
but really enjoy it.

Mr. Hutchinson,
There is an article that states: When Vitamin D has been restored, intestinal absorption of calcium is as much as quadrupled. Does that mean the calcium consumed from food is sufficient----assuming the person's diet has calcium-rich foods included?

YES
There are plenty of online calcium calculators that allow you to enter you daily foods and work out if they meet the CALCIUM RDA for your age/sex. You will also get some calcium from your water supply. In the UK tapwater is generally of reasonable quality and water suppliers generally list mineral quality on their websites or will supply this information when asked.
Given the risk of stroke from excess calcium supplement use I believe no more than 600mg/daily should come from calcium supplements.

I think it's far more important to take MAGNESIUM, which acts as a natural calcium channel blocker and counterbalances the actions of calcium. More people are magnesium deficient than calcium deficient. Vitamin K is also important to keep calcium under control and locked away in bones rather than circulating in the bloodstream.

Lecturer Hutchinson,

Your information is greatly appreciated--Thank You!!

How much do we need a day and how to get Vit. K in foods. Thank you.

Can you tell me how much Vitamin K we need and should we take it with Vitamin D?

I really appreciate your help; I went to the information and it was just what I wanted to know. As for bone marrow, I am a vegetarian, so that is not an option.
