Vitamin D Isn’t Vitamin Me, BUT It’s Just As Good for YOU!

So although I DO like to think everyone needs a lil’ bit of ME in their life…that’s not the necessary D we’re talkin’ about today…it’s Vitamin D that’s the word.

What is It?

Vitamin D is crucial for the absorption and metabolism of calcium and phosphorous, which have various functions in the body, especially for the maintenance of healthy bones. Vitamin D is also an immune system regulator. There are many studies in process that are studying the effects of Vitamin D on Multiple Sclerosis, brain function, maintaining a healthy body weight, among many others.

How Do I GET Vitamin D?

While in the summer months ‘The D” is easy to come by from the sun, but only a few common foods are good vitamin D sources. Current daily recommendation: 200 to 600 IU, but some doctors propose 1000-1500 IU per day. Below are some common foods listed in International Units (IU) per serving. :

  • Cod liver oil, 1 tablespoon                  1,360
  • Salmon, cooked, 3½ ounces                 360
  • Mackerel, cooked, 3½ ounces              345
  • Tuna fish, canned in oil, 3 ounces          200
  • Sardines, canned in oil,1¾ ounces        250
  • Milk, vitamin D fortified, 1 cup                  98
  • Margarine, fortified, 1 tablespoon            60
  • Egg, 1 whole (vitamin D is in egg yolk)     20
  • Liver, beef, cooked, 3½ ounces              15
  • Cheese, Swiss, 1 ounce                           12

D is Reason to Move to the Equator (or less dramatic, take a vacation)!

If you live in the tropics and can expose your unprotected (aka no sunscreen) skin to two sessions of 15 minutes of sunlight each week your body will naturally produce adequate amounts of vitamin D. The following factors may reduce your body’s vitamin D synthesis:

  • If you live far from the equator, your sunlight exposure will be less during many months of the year (like NYC right now!)
  • Cloud cover
  • Smog
  • Sunscreens

Good news for Snookie! You CAN get vitamin D from tanning beds. The ultraviolet rays are what spurs the production on Vit D in your bod. Common sense is KEY. Two 15 minute sunscreen-free sessions per week will create enough D, so be smart! If your body can’t produce enough vitamin D because of insufficient sunlight exposure (or an aversion to looking like the JWow or Paulie D) you will need to obtain it from foods (above) and or supplements.

Supplements

Supplements contain the nutrient, but most use D-2 — that is far less potent than the more desirable D-3. Multivitamins typically contain only small amounts of D-2 and include vitamin A, which offsets many of D’s benefits. As a result, pills might not raise vitamin D levels much at all.

Take time to learn about your bod. Be smart, use common sense and try to get your D!

Sending you love! Have a fantastic weekend…’see’ you Monday!

  1. I take Vitamin D tablets specifically and not multivitamins. Still I am not getting benefited? What’s the diff between D-2 and D-3?

    • Vitamin D2 is synthesized by plants. Vitamin D3 is synthesized by humans in the skin when it is exposed to ultraviolet B (UVB) rays from sunlight. Foods may be fortified with vitamin D2 or D3. Taking supplements can be helpful, but absorption is not necessarily absorbed into your body in the amount of the tablet (i.e. if there is a 1000IU tablet you may not be absorbing all 1000IUs).
