No, Vitamin D And Calcium Supplements Still Don’t Work

I think you should add calcium to your list of top 6 supplements that you shouldn’t take. Here’s why:

A year and a half ago, I studied a very reported on a large-scale study.

Well, that’s not true. What the research found was that People who take vitamin D have exactly the same risk of bone fractures as people who don’t. It didn’t matter how much vitamin D they took, and even if they took calcium in supplements, it had no effect. In any case, vitamin D had no effect.

Well, for now huge new researchjust go outside Annual report of internal medicine, followed over 36,000 older women and investigated the effects of a combination of vitamin D and calcium over a 22-year period. (This is a very long time for a study, and we commend the authors for their determination and effort.) The scientists who led this study did not only study the effects of supplements on femoral neck fractures, but also We also looked at whether this changes the risk of dying from cancer. Or heart disease.

result? Now, research has revealed that No reduction There is an increased risk of femoral neck fractures, which is not surprising given that previous studies have found the same. But this study was a very long-term study that followed people for more than 20 years, so he could have asked something else. Did vitamin D and calcium have any effect on mortality? More frankly, did the supplements prevent death?

Hmm, no. However, the report was a little more nuanced than that. It was found that deaths from cancer decreased slightly and deaths from heart disease increased slightly.

First of all, let me explain the whole experiment. About half of the women in the study, just over 18,000, were assigned to take both vitamin D and calcium daily. They were given tablets containing 1000 mg of calcium carbonate (400 mg of elemental calcium) and 400 IU of vitamin D.₃ every day. The other half of the participants took a placebo pill, but neither group knew whether their pill was a placebo.

Over 22 years, 1,817 women who took the supplement died of cancer compared to 1,943 women in the placebo group. That’s kind of nice. The study authors report that this result (126 fewer deaths) was statistically significant (barely), but there are good reasons to be skeptical of this “significant” claim. .

Meanwhile, 2,621 women who took the supplement died from heart disease, compared to 2,420 in the placebo group. So women who took vitamin D and calcium had 201 more deaths from heart disease, which isn’t much better.

Combining both causes of death, we find that women taking the supplement had over 75 more deaths from cancer or heart disease. The study also reported figures for all causes of death, but the causes of death remained small. more Mortality in the supplement group. (The annual mortality rate for supplement takers increased from 2.14% to 2.15%, but this is not a significant change.)

So overall, taking supplements didn’t seem to provide any benefit or reduce the risk of death.

Why would supplementing with vitamin D and calcium increase the incidence of heart disease or decrease the incidence of cancer? First, it’s entirely possible that these supplements have no effect at all, and may reduce mortality. It must be emphasized that the difference in must be just a random variation. Several studies have speculated on how vitamin D may help prevent cancer, but the effects are very small, if any. And when it comes to heart disease, perhaps, the authors of a new study speculate, long-term calcium supplements can cause calcification in coronary arteries, which could be bad. For now, this is just a hypothesis.

So here’s a new list of the top 7 (now 6) supplements you shouldn’t take.

1. vitamin C
2. vitamin A and beta carotene
3. vitamin E
4. vitamin B6
5. multivitamin
6. vitamin D
7. calcium

What’s left? If you don’t have a vitamin deficiency, there is no need to take vitamin supplements at all. If you want to spend a little more money at the grocery store, buy fresh fruit instead. You will be healthier because of it.

As a final note, I would like to point out the following:There is no point in taking supplements on a daily basis, and large doses of vitamins can be harmful, but If you think you have a vitamin deficiency, talk to your doctor. Severe vitamin deficiencies may be the result of other health problems, and your doctor may be able to help you manage them. Vitamins may also be included in treatments for certain conditions or illnesses.
