What Is Vitamin D?

Vitamin D is both a hormone and a vitamin. It's considered a fat-soluble vitamin because it dissolves in fat (aka it needs fat to be absorbed) and is stored in your body fat, according to the National Institutes of Health (NIH). Unlike water-soluble vitamins, which are easily excreted, fat-soluble vitamins like D can build up in the body, so it's possible to get too much.

There are two forms of vitamin D — D2 and D3. Both are beneficial in raising vitamin D levels in your body, and there is inconclusive evidence to support the use of one over the other.

At low doses (1,000 IU), both forms of vitamin D appear to be effective, but in high doses, D3 may be slightly more beneficial, per the NIH.

Food Sources of Vitamin D

There are very few natural food sources of vitamin D. Some of them include:

  • Salmon, tuna, trout, sardines
  • Egg yolks
  • Fortified foods: Milk, orange juice, breakfast cereals

Mushrooms grown in UV light may also have vitamin D (look for a note about that on the mushrooms' packaging).

Do I Need a Supplement?

You only need about five minutes outside with your arms and legs exposed, twice a week, to get enough vitamin D, per the NIH. But that sun exposure is a double-edged sword: Too much can up your risk for developing skin cancer, according to the American Cancer Society.

If it's challenging to get enough sun and fit vitamin-D-rich-foods in your diet, taking a supplement is an alternative option. You should confirm your need for a vitamin with your doctor.

Some people are more prone to vitamin D deficiency. According to the NIH, factors that put you at a higher risk include:

  • Advancing Age​ – As you age, your skin's ability to produce vitamin D declines. Those over 65 only produce one-fourth as much vitamin D as adults in their 20's.
  • Darker Skin Color​ – Skin with more melanin (darker tones) typically retains less vitamin D.
  • Little Exposure to Sunlight​ – Not having access or the ability to get those rays of sun, reduce one's potential for obtaining sufficient vitamin D.
  • Obesity​ – Because vitamin D is stored in fat, obese individuals have less Vitamin D circulating in the blood – limiting the availability for the body to use it.
  • Malabsorption Issues​ — Inflammatory bowel disease, cystic fibrosis and liver disease are among those diseases that make it difficult for the body to absorb vitamin D.

Symptoms of deficiency include:

  • Fatigue
  • Muscle weakness
  • Joint pain
  • Mood changes

If you're concerned that you may be deficient because of any of these risk factors, talk to your doctor who can confirm by administering a blood test.

How Much Vitamin D Do You Actually Need?

Anyone over the age of 1 needs 600 IU of vitamin D every day, and adults over 70 need 800 IU per day, according to the NIH.

Keep in mind that more is not always better when it comes to any nutrient. While it's not likely you'll get too much vitamin D from the sun, you can get too much from a supplement, which can lead to side effects like vitamin D toxicity, per the Mayo Clinic.

Vitamin D toxicity can cause calcium to build up in your bloodstream, which can lead to side effects such as:

  • nausea
  • vomiting
  • weakness
  • frequent urination

Vitamin D toxicity might progress to bone pain and kidney problems, such as kidney stones. Reach out to your doctor right away if you think you have vitamin D toxicity.

To avoid this problem, keep your daily dose below 4,000 IU, per the NIH. Go for supplements that offer 1,000 or 2,000 IU unless otherwise directed.

Potential Interactions

High doses of vitamin D and blood pressure medications such as Diltiazem, Verapamil and Thiazide diuretics can increase your risk of hypercalcemia and reduce the effectiveness of the drug, according to the Mayo Clinic.

Also, be cautious about supplementing vitamin D when on the heart medication Digoxin, as it may also raise your blood calcium to higher-than-normal levels, increasing your risk of heart attack.

If you're taking any medications, talk to your doctor before taking vitamin D supplements to avoid harmful interactions.

What to Look for in a Vitamin D Supplement

You have a lot of choices when it comes to vitamin D supplements. Here's a list of what to look for to get you started.

Quality

Basically, you always want to check if your supplement is what it says it is and does what it's supposed to do by looking for things like third-party testing and certification.

Dietary supplements aren't tightly regulated by the Food and Drug Administration (FDA), though it does set Current Good Manufacturing Practices (CGMPs) for companies to follow. Brands also often seek a third-party verification from trusted organizations like Consumer Lab, U.S. Pharmacopeia or NSF International.

If a supplement brand uses CGMPs and/or has been third-party tested, it will often be listed on the product label or brand website.

Strength

Dosages on supplements can range pretty widely. As mentioned, the one with the most isn't always better. Opt for vitamin D supplements with 1,000 IU or 2,000 IU, and remember it's best to stick below the recommended 4,000 IU unless your doctor says you need it (in which case, you will likely be given a prescription).

Delivery Method

Vitamin D supplements are available in tablets, softgels, drops and gummies or chews, and you have the choice to take your vitamin D in any form that works best for you. If you have difficulty swallowing pills, chewables or gummies may be better options, for example.

Ingredients

Vitamin D3 can be obtained from several sources. If you eat a vegan diet, you'll want to look for one sourced from algae oil (lichen) versus fish oil or lanolin (from sheep's wool). Additionally, check for added sugars and other additives such as artificial colors or flavors on your product labels.
