Vitamin D and the Lab



Vitamin D and the lab

Everyone should know their Vitamin D levels at some point. There has been a huge flap when Quest Lab acknowledged errors and alerted everyone they screwed up.

Quest’s comments are also found at,

As noted on a prior eNews, Vitamin D testing is also available,

This last link will get into steadily increasing information about Vitamin D that will not plateau for the next 10 years. Your data, if you wish will be part of a giant program, will be used to determine how ultimately vitamin D would be used in multiple situations. Your data can help determine success of treatments. New treatment systems with D can be brought in to play and used immediately due to the ability to continue monitoring your situation. Nice.

Your body handles increasing levels of Vitamin D without problems. The values in the blood go up increasingly as you take higher levels of Vitamin D. When all the sites are saturated, the body will not allow any more Vitamin D in and the blood levels begin to fall.

If you take 50,000 IU of Vitamin D daily the blood values will go up to about 200 days and then decline to values that often will be less that the original values prior to starting. These are values from people in my practice who wanted to know these values and have them measured.

An industrial accident I was not associated with gave a gentleman 1.4 million units of Vitamin D3 daily and found that the blood levels were lower than his original levels. No other data is available.

So “toxicity” does not occur unless supplemental Calcium is taken with Vitamin D. I don’t use vitamin D2 because it does not have enough sustained effect. These are new thoughts and explanations for the phenomenon in endocrine/metabolic situations that I have observed since 1964.

When Vit D levels go back to lower levels than when you started, what on earth do you do?

Continue to “top it off” by staying at the same level of Vitamin D3. Further blood tests are not needed.

Dr. Joe,

I'm still not clear about the intake of Calcium. You said in this video to "take the normal amount of calcium", yet you said "not to take calcium". What do you recommend? Do we take calcium or not?

Thank you,

Linda

Use no supplemental CALCIUM. Food is fine.

Dr. Joe said...

Don’t take Calcium.
