Vitamin D: Too Much Can Harm Your Kidneys

Study: Taking too many vitamins can lead to%

Vitamin D promotes calcium absorption in the body, and having enough is central to health and well-being, offering the promise of protecting bones and preventing bone diseases like osteoporosis, per the NIH. Supplemental vitamin D is popular because its difficult to get enough from food.

Also, as the Centers for Disease Control and Prevention notes, our bodies make vitamin D when bare skin is exposed to direct sunlight, but increased time spent indoors and widespread use of sunblock, as a necessary way to prevent skin aging and skin cancer, has minimized the amount of vitamin D many of us get from sun exposure.

But vitamin D supplements are a tricky topic. Sometimes, it can seem that guidelines and research contradict one another. The truth is, enthusiasm for vitamin D supplements is outpacing the evidence.

For example, when healthy pre- and postmenopausal women take vitamin D , it does not necessarily prevent them from breaking bones, according to a 2018 U.S. Preventive Services Task Force.

And taking high doses is not a good option. In healthy people, vitamin D blood levels higher than 100 nanograms per milliliter can trigger extra calcium absorption and lead to muscle pain, mood disorders, abdominal pain, and kidney stones, notes the Cleveland Clinic. It may also raise the risk of heart attack and stroke.

More is not necessarily better when it comes to micronutrient supplements, says Dr. Manson.

How Much Vitamin C Do You Need in 2020

Calcium is essential for a strong skeleton, but as with all nutrients, too much of this mineral may be harmful. As the NIH notes, more than 2,500 mg per day for adults ages 19 to 50, and more than 2,000 mg per day for individuals 51 and over, can lead to problems.

With calcium supplements, hardened arteries, or atherosclerosis, and a higher risk for heart disease, are risks, though research is mixed, according to the Cleveland Clinic.

Get calcium from your diet if you can, advises Dr. Millstine, noting that research shows that calcium is better absorbed through food than through supplements. In a study, researchers analyzed a group of about 5,450 healthy adults calcium intake and screened their hearts for calcium deposits associated with atherosclerosis over 10 years. They found that people who got their calcium from food had a lower risk of atherosclerosis, while calcium supplements were associated with an increased risk of the atherosclerosis.

The NIH recommends 1,000 mg of calcium a day for women ages 19 to 50 and 1,200 mg a day for women 51 and older. The recommendation for men ages 19 to 70 is 1,000 mg a day and 1,200 mg a day for men 71 and older. According to the Dietary Guidelines for Americans, there are various food sources of calcium, including plain low-fat yogurt, tofu, nonfat milk, cheese, and fortified cereal and juices.

How Much Vitamin C Should A Pregnant Woman Take Daily

To begin any discussion about vitamin C consumption, its first important to examine the dietary options available for obtaining vitamin C through the foods we eat. A balanced diet is essential for health and wellness. During pregnancy, this is even more true. A well-balanced diet supports both the pregnant persons body and the growing embryo. Foods that are rich in vitamin C include:

  • Raw Red and Green Peppers
  • Oranges and Orange Juice
  • Brussels sprouts

When choosing vitamin C-rich foods to eat, its best to consume raw fruits and vegetables over cooked ones, since cooking can decrease levels of the vitamin. Eating a variety of fresh fruits, vegetables, and whole grains can provide the micronutrients that support your health and the health of your baby. A balanced diet filled with whole foods, rather than highly processed foods, provides the micronutrients such as folic acid, zinc, and iron that help support a healthy pregnancy. If it is a challenge to eat a wide variety of fresh foods, supplementing with vitamin C is another option.

Subtle Signs You’re Getting Too Much

Should you take vitamins?

“I have not seen someone off the street who was taking a toxic level of vitamin A or D — those are very unusual,” says David Katz, MD, director of the Yale University Prevention Research Center in New Haven, CT, whose medical practice specializes in nutrition. “What I’m more likely to see is a person with a dosing level of supplements that’s higher than optimal.”

Scientists don’t yet know if routinely getting a little bit too much of a vitamin or mineral is a problem, Katz says.

“There might be hints of concern, but they would be very subtle signs,” he says.

These fairly mild symptoms may include difficulty sleeping or concentrating, nerve problems such as numbness or tingling, or feeling more irritable — depending on the nutrient that’s going overboard.

The bigger concern, Katz says, is that we’re “garnishing the food supply with overfortification.”

He says manufacturers have shifted their focus from what they’ve taken out of food — such as its fat, sugar, or salt — to what they’re putting in, whether it’s vitamin D, probiotics, or omega-3 fats — whatever nutrient is in vogue.

“When more and more foods are enhanced, it becomes impossible for consumers to know what dose they’re getting over the course of a day,” Katz says. “Clinicians have to realize we might be introducing new dietary imbalances because of this practice.”

A Closer Look At Major Minerals

The body needs, and stores, fairly large amounts of the major minerals. These minerals are no more important to your health than the trace minerals theyre just present in your body in greater amounts.

Major minerals travel through the body in various ways. Potassium, for example, is quickly absorbed into the bloodstream, where it circulates freely and is excreted by the kidneys, much like a water-soluble vitamin. Calcium is more like a fat-soluble vitamin because it requires a carrier for absorption and transport.

Ask Dr. Nandi: Should you take Vitamin B12 to boost mood?

Many of the terms you see on labels or supplement web sites can help you understand how much of the vitamin or mineral you should take. For example, here are some guidelines set up by the Institute of Medicine:

The RDA and the AI are the amounts of a vitamin or mineral you need to keep healthy and stay well-nourished. They’re tailored to women, men, and specific age groups.

The UL is the maximum amount of daily vitamins and minerals that you can safely take without risk of an overdose or serious side effects. For certain nutrients, the higher you go above the UL, the greater the chance you’ll have problems.

The DV is the only measurement you’ll find on food and supplement labels. That’s because space is limited, and there’s a need for one single reference number. That number is the amount of a vitamin or nutrient that you should get for top health from a diet of 2,000 calories a day. The DV is sometimes the same as the RDA.

Although the details may be different, remember that the RDA and DV are both set up to help you get the nutrients you need to prevent disease and avoid problems caused by lack of nutrition.
