Recent studies say taking extra amount is of the nutrient may not be a boon for every body

In the supplement world, vitamin D is a bit like a Kardashian. Its fame seemed to come out of nowhere about a decade ago, garnering so much press so fast that it’s hard to remember a time when people weren’t talking about it.
Vitamin D had long been known for protecting bones, but its star began to rise in the early 2000s after researchers made connections hinting that vitamin D was good for a lot more than our skeletons. It appeared to help protect against a lengthy list of ailments, including multiple sclerosis, asthma, depression, heart disease and cancer. The vitamin also was said to improve athletic performance.
Organizations like the Vitamin D Council — the 2003 brainchild of a psychiatrist who became a vitamin D enthusiast — began to actively promote the benefits to the public and to physicians, while selling test kits for vitamin D blood levels. Doctors checked for it; patients demanded testing. Researchers latched on.
But with more research comes more scrutiny, and most recently, a series of seemingly tarnishing findings. On November 10, the New England Journal of Medicine published the largest study so far to test vitamin D supplements’ protection against cancer and heart disease. The results were generally interpreted as inconclusive at best and disappointing at worst. One 2017 review of the evidence for cardiovascular benefits concluded that studies of people taking vitamin D “have failed to show clear improvements in blood pressure, insulin sensitivity or lipid parameters.”
Even the vitamin’s reputation for helping bones took a hit last April from the U.S. Preventive Services Task Force.

Thanks for mentioning D3.
I have a problem that the referenced article doesn’t distinguish between D2 and D3, D3 long argued to be a better formulation, D2 used in milk.
Note that skin produces D3 when exposed to sunlight. The problem is that the skin’s D3 is not immediately bioavailable. And if you clean up every day then it is argued that you’re washing off the D3 before it can hit target. So D3 supplement is said to be a good idea if you work in office and clean up every day.
Corrections, insights welcome.
There’s always some nutrition fad going. The only thing I emphasize in nutrition is getting enough protein, and that doesn’t mean consuming it until it comes out my ears.
Vitamin D works it’s magic when the body is saturated with Vitamin K2 and vitamin B2. If you are not getting enough from your diet of each, through food or the conversion of K1 to K2 by various gut bacteria, then high dosages of vitamin D can become problematic and cause calcium to become very damaging to the vascular system. In addition, vitamin D must be properly sinthysized by your body to improve the arming of macrophages, which destroy pathogens.
To put it simply, vitamin D does not work best alone and taking high dosages without other necessary nutrients can become problematic. There is plenty of research highlighting this, which goes back many decades, but for some reason, chosen main stream researchers choose to ignore such facts and information.
In Dynamic Health and Strength!
D3 is really good to take. The VA told hubby to take D2 instead, which is nuts. D2 is synthetic and does not work well.
One problem is that doctors don’t usually order Vitamin D 3 hydroxy in your lab workup unless you ask for it. I did that about a year ago and found I very deficient in D 3 hydroxy. I always take it now. That and B 12 and Biotin for skin and hair. Seems to be working well.
I’m do 5,000IU twice a day and K2 200mg. I love our FReeper family.
It shows promise with MS, and possibly colon cancer, but look at the results for D and prostate - which makes two vitamins men may want to talk to their doctor about (Vit A and eversmoked, being the other)
don’t forget that D is fat-soluble, that is, you’re not going to pee out what your body can’t use, so definitely take care to have your levels monitored so you don’t add to your problems with getting kidney stones.
I take 4,000 D3 and 100 K2.
While it is very good to increase one’s intake of Vitamin D3, I’ve been told that taking a concentrated for of the Vitamin actually reverses the intended effect. It is far better for the nutrient to be naturally balanced in one’s food, rather than as a pill or gel tab.
I’ve seen other advice recommending min 8000IU of D3 daily to others suggesting min of 400IU daily and it could be taken in 7X daily does once a week.
Apparently, there are risks of having D3 overdose. Also recommendations are made to have 30 min of sun exposure to the hands and chest, without sunscreen, daily to naturally produce the D3 in the blood stream.
Had younger women only taken this advice to go topless for 30 min during their lunch breaks they would have such stronger bones today,.....I would have encouraged them, but they would always think I had ulterior motives. Alas.
same here. VA had me take 50,000 iu a day for 10 days. Then 10,000 iu a day there after.
They are no longer touting D3 and I haven’t taken it in over a year.
They are no long giving the PSA test.
The are no longer forcing statins, but rather are asking.
All the pills I do take deplete something else. So I am prescribed additional different pills.
I’m tempted to stop taking everything.
If you want the benefits of Vitamin D, get outside in the sun more.......
“I read Dr. Mercola’s website a lot “
Yep. I drink four cans of his hydrogen-infused water each day.
I am also living proof of his theory that as the tummy gets larger the brain gets smaller.
“I think that’s it. There aren’t many more vitamins.”
Oldies never die. They get recycled.
Hypes very rarely do.
Vitamin D is critical for people with M.S.
I believe in eating a diet which includes all necessary nutrients. It’s totally possible if it includes foods with added vitamins and minerals and uses foods that haven’t had all of the fiber and healthy parts processed out of them.
Not so fast there... When these guys talk about Vitamin D supplements they are talking about D2 which has only a portion of what D3 has, which is the WalMart available supplement. D2 is totally synthetic and contains those parts deemed beneficial by doctors a long time ago. I can attest to D3 at least preventing respiratory viruses. All my family take it through the winter and I work at night so I take it all year and none of us has had a cold or flu so long as we have been “on” it. Several women I know are no longer manic depressive after I got them started with D3. My daughter started on it and stopped taking Xanax a month later.
D3 is still not so good as getting a lot of sunshine but in the winter when the sun is at a low angle and one is dressed against the cold you don’t get that sunshine benefit from it. I don’t know about bones and cancer but it is the magic bullet for viruses and clinical depression.
I work with many people with Multiple Sclerosis. Vitamin D really works best with enough daily K2. To realize optimal benefits, you most likely need K2 in the MG. 5 to 45mg.
5000 iu for me, too, since 2006 also. I started three miserable days into a flu that had many people hereabouts abed for 2-3 weeks. 8 hours later I was FINE. Wife did the same the following year.
I take an organic combo D3/K2 each day - 5k.
I’ve had fantastic success killing off the flu by taking 50k the first day I feel it coming.
Then 50k each day for up to 4 days. Plus fluids, plus garlic supplement.
