Vitamin D2 or Vitamin D3: Which Should You Take Now?

You’ll have noticed, no doubt, the sun sneaking below the horizon earlier and earlier these days. Not only does that mean a darker commute home in the evenings, but fewer opportunities to catch some all-important rays. Since the human body synthesizes most of its Vitamin D from sunlight, wherever will we get the Vitamin D we need?!?

Why Do I Need Vitamin D?

Vitamin D deficiency has been linked to a number of physical and mental disorders ranging from osteoporosis to schizophrenia. It has been indicated in the development of diabetes, cancer, cardiovascular disease, and plays a significant role in immunity.

The CDC reports that, as of 2006, 25% of the American population was deficient in Vitamin D – and that includes states that enjoy sunny days year-round!  For those of us living north of the border, we don’t have enough access to the sun’s rays for about 8 months of the year. Our numbers are bound to be even worse.

Recent studies are linking depression and SAD (Seasonal Affective Disorder) to low levels of Vitamin D. If you find yourself feeling especially blue during the winter months, Vitamin D may just be the nutrient to help.


Where Do I Get My Vitamin D?

Once the earth tilts into fall and winter, and we can’t synthesize it from the sunlight as well, our Vitamin D levels plummet. We can get some Vitamin D from food: Vitamin D3 from animal sources like fish, egg yolks, and raw milk, and trace amounts of Vitamin D2 from plant sources (mushrooms and some fortified foods), but it’s rarely enough to keep up with our bodies’ needs.

For many of us (particularly the vegetarians and vegans of the world), Vitamin D supplementation is our only option. But which is the right Vitamin D for you?

Vitamin D2 or D3?

There are two forms of Vitamin D available on the market. Vitamin D2 (ergocalciferol) is often referred to as the “vegan” Vitamin D, as it is synthetically produced. Vitamin D3 (cholecalciferol) is the animal form of Vitamin D. So which one should you choose?

Studies have shown that both forms are helpful for the treatment of rickets, but D2 must be taken at much higher doses to achieve the same effect. Vitamin D3 is much more potent (87%!),  it converts to a usable form 500% faster, and raises the body’s storage levels of Vitamin D for a longer period of time. Other studies have shown that Vitamin D3 is more effective for other illnesses and conditions, even going as far as to say that Vitamin D2 has “no statistically significant beneficial effects“.


Pills or Liquid?

Generally, liquid forms of D3 are considered to be superior, as D is a fat-soluble vitamin, and they are already dissolved in oil. In a recent study, researchers found that liquid Vitamin D raises serum Vitamin D levels the most significantly (as compared with tablets and capsules). Liquid vitamin supplements are also more readily absorbable for those with compromised digestion.

As a result, we carry both Vitamin D drops, and Vitamin D liquid in capsules, so you can purchase according to your preference!

Come on in and pick up your choice soon, and keep yourself happy and healthy through the winter months ahead!
