I take 5,000 IUs every day.

Doc put me on that for the month prior to hip replacement in 2020, and I felt great. Then Covid came, and D3 was recommended for prevention. So I never stopped taking it.

I’m still old though. My telomeres must be defective or something.

Interesting article, Red. What strikes me is the wildly contradictory data (U.S. vs U.K.), difficulty of measurement, and widely divergent opinions.

I’m 73 and spend some months in North Idaho where we don’t get a lot of sunlight and some months in the San Fran Bay Area were we get a lot more sun. I started taking 2,000 IU of Vitamin D per day as part of the COVID Protocols in March 2020.

After five years of Vitamin D, my telomeres are now so long that I can feel them tickling the insides of my cells.

Me too!...................

I’m 74 and take 12000 IU’s of D3 per day with vit, K2 which is recommended to take with D3.
I’ll drop my intake soon because of more exposure to the sun this spring and summer.

You might take vit K-2 in conjunction.

Best wishes.

Me three.
Democrats take 1,000,000 IUs of vitamin S daily.

Excess vitamin D reduces vitamin K and that damages teeth.

[TheThirdRuffian]

Vitamin k also sucks calcium out of your blood vessels and back into your bones (a good thing)

[Red Badger]

What teeth?...............

[bobbo666]

Some years ago my PCP tested blood and said my D was on low side of normal. So, take an OTC gel capsule . Did so. Six months later D concentration was high normal.

They cost practically nothing and cause no side effects at that dosage. Not testing for this is BS.

For some ODD REASON, Medicare doesn’t pay for Vitamin D Blood Testing..............hmmmmmmm.......................

[struggle]

There’s also that Israeli study from 2021 that showed that low Vit D increased COVID symptoms.

You might take vit K-2 in conjunction.

I know! I can’t believe these studies make no mention of the necessary K2 (abt 90-100 mcg/day) to go along with the recommended D3.

K2 it was keeps the calcium out of your arteries and *pushes* it into your bones, where you need it for strong bones.

How to Safely Get Vitamin D From Sunlight

Good article. Very informative.

[Georgia Girl 2]

We take 4,000 iu of D3 daily as part of the Zelenko protocol. We haven’t had a sniffle since Nov 2022. I think that’s when we had covid which for us was a 3 day mild head cold and a lingering cough. We were never really sick. We never bothered to get tested.

If you are over 55 you should be on the Zelenko protocol. Our doctor can’t understand how we look, act and feel so much younger than our age.
