vitamin D3 — not D2

I’m being lazy again today, quoting something that I want to share with you. Here is the executive summary from the Dr. Mercola newsletter today. The article is titled, “If You Take Oral Vitamin D You MUST Avoid Making This Serious Mistake. I quote:

A meta-analysis of 50 trials looking at mortality rates for “doctor recommended” synthetic vitamin D supplements versus natural vitamin D3 shows a six percent risk reduction among those who used D3, compared to a two percent increased risk among those who used D2.

  • Research shows vitamin D3 is approximately 87 percent more potent in raising and maintaining vitamin D concentrations and produces 2- to 3-fold greater storage of vitamin D than does D2. D3 is also converted into its active form 500 percent faster.
  • Plant-based food sources that contain vitamin D provide vitamin D2. Only animal-based food sources, such as fish, egg yolk, and raw milk, contain D3.
  • Optimizing your vitamin D levels may be one of the most important steps you can take in support of your long-term health. The ideal way to do this is by exposing large amounts of skin to sunlight or a safe tanning bed, but if you need to use an oral supplement, make sure you’re taking vitamin D3.
  • The most important factor is your vitamin D serum level, which should ideally be between 50-70 ng/ml. When taking an oral vitamin D supplement, you should take enough to reach and maintain this therapeutic level. As a generic guideline, adults need to take about 8,000 IU’s a day to reach this level.

I am not a proponent of using a tanning bed, even a safe one, but I agree with the concept that getting some sun can be good for you.

It’s cloudy here today, deeply overcast, so we will have to find other ways to bring sunshine into our lives!

All best,

Carolyn
