I've never heard of calcium as an immune support!
Can't edit my post anymore...meant vit C!

However, I did do a little research just for the fun of it and did find benefits of calcium and the immune system.

How Much Vitamin D Should You Take?
How much vitamin D you need depends on many factors. These include age, race, latitude, season, sun exposure, clothing and more.

Recommendations from the US Institute of Medicine suggest that an average daily intake of 400–800 IU, or 10–20 micrograms, is adequate for 97.5% of individuals (21Trusted Source, 22Trusted Source).

However, some studies have shown that the daily intake needs to be higher than that if you aren’t being exposed to sun.

Depending on who you ask, blood levels above 20 ng/ml or 30 ng/ml are considered as “sufficient.” One study of healthy adults showed that a daily intake of 1120–1680 IU was needed to maintain sufficient blood levels (23Trusted Source).

In the same study, individuals who were vitamin D deficient needed 5000 IU to reach blood levels above 30 ng/ml.

Studies in postmenopausal women with vitamin D levels below 20 ng/ml found that ingesting 800–2000 IU raised blood levels above 20 ng/ml. However, higher doses were needed to reach 30 ng/ml (24Trusted Source, 25Trusted Source).

Overweight or obese individuals may also need higher amounts of vitamin D (26Trusted Source, 27Trusted Source).

All things considered, a daily vitamin D intake of 1000–4000 IU, or 25–100 micrograms, should be enough to ensure optimal blood levels in most people.

4000 IU is the safe upper limit according to the Institute of Medicine (IOM). Make sure not to take more than that without consulting with a health professional.
Definitely consult a health professional prior to taking any sort of high dose.

Based on this:
Weight divided by 20 x 1000.
I would be taking 6000 IU a day which seems like way way too much.

As far as calcium I’ve always been told 1,000 mg unless you’re getting no calcium from food sources or you’re over 70 years of age.
Everything I quickly just read seems to support this.

I get vitamin D in my calcium supplement, plus I go walking several times a week (outside) so I get it naturally, too. Zinc makes me a little nauseous, which is highly unusual for me, so I stay away from it.

The amounts calculated and mentioned sound way too high, though! I only get 1,000 with my supplements, plus smaller amounts I get with food.

I did read this on WebMD (not sure how accurate that is): Too much vitaminD can cause an abnormally high blood calcium level, which could result in nausea, constipation, confusion, abnormal heart rhythm, and even kidney stones.

The doctors recommended that much?

I take a women’s multi vitamin daily and know most doctors, generally, suggest it as in the United States we tend to not get enough daily nutrition from what we are eating.
To me, anybody in good health and with appropriate levels of vitamins in their blood/body is going to fare better with Covid than somebody not in good health.

I would also be cautious in taking to much of any one vitamin.

For anyone interested, some good articles on Covid and Vitamin D/Zinc:

Great info. THANK YOU!

RamonaQuimby 01-18-2021 05:17 AM

I believe Vitamin D is one of those that you need to check with a professional on if you are taking more than the recommended dose as it doesn't leave the body like other vitamins and too much built up in your body can lead to problems.

teachnkids 01-17-2021 08:59 PM

Yes!!! My chiropractor is a firm believer in this info too!

He says you should be taking the right amount of D3. Calculate this way

Weight divided by 20 x 1000. That's how many IUs you should take a day.

Calcium he said roughly 2000mg a day. If you feel sickness coming on triple it.

Keep zinc lozenges handy in case of illness.

Thank you so much for posting this reminder. I didn't know this about VD3, although I take it 5,000 units a day.

Just a reminder that taking Vitamin D3 is supposed to help people resist COVID. This was told me by a surgeon in August and I keep seeing other doctors recommend it. It wouldn't hurt to add in Vitamin C and have some Zinc on hand at the first hint of a cold, flu or COVID.
