Vitamin D at Glow 20% off

By Candace McNaughton ND

Just mention “Sunshine finally” to redeem your discount. Glow has several options for vitamin D depending on your needs, blood levels, and personal preference.  They are all the active form, D3.  We have PhysioLogics’ Vitamin D3 2000 IU in the pill form.  We also have Genestra’s D-mulsion, which is 1000 IU per drop, with 1200 drops per 1 ounce bottle.  It has a bit of a creamy texture and it’s in a mildly sweet base, perfect for just dropping right on the tongue!  Our Thorne Basic Prenatal also has 1000 IU of D3 per three caps. It can be used by patients who are not pregnant, as it is simply a high dose vegetarian multivitamin-mineral formula which contains iron and superiorly absorbed forms of all of the nutrients.  I use it for my patients who show low blood levels of iron.  Let us know if you have any questions!

Sometimes when research is summarized to one sentence, the message is skewed.  The US Preventative Services Task Force has issued a draft statement saying that vitamin D and calcium should not be taken by healthy men or post-menopausal women to reduce fractures and that it may not prevent cancer.[1]  The evidence is mixed and many-layered, but because we are trained for take-home messages and sound bites, many will simply conclude “Don’t take vitamin D or calcium.”

Actually, they say that they can’t recommend for or against it.  More specifically, they say that 400 IU of vitamin D3 and 1000 mg of calcium carbonate don’t reduce osteoporotic fractures in men or postmenopausal women living at home as much as those living in facilities.  However, the risk is reduced in those living at home.  I think the difference could be because of missed doses. Although D3 is considered to be the active form, some studies use D2. Also, 400 IU of D3 is not a very high dose.  Calcium carbonate is the poorest absorbed form of calcium.  Bone density is best supported with a combination of well-absorbed calcium, vitamin D3, vitamin K, other minerals such as strontium and boron, and weight-bearing exercise. The task force reviewed 19 randomized trials and 28 observational studies (for cancer outcomes).  There are close to 18,000 studies that focus on vitamin D.

The task force reports that there is evidence of decreased risk of cancer, but found some evidence that high blood levels may be associated with an increased risk of cancer. A simple, inexpensive blood test that we commonly run here at Glow can make sure your blood levels don’t get too high. However, there is some evidence that higher blood levels may reduce the risk of colorectal cancer.

There is clear evidence that people with low blood levels of vitamin D have increased risk of heart disease, stroke, high blood pressure, and diabetes.  Further, some studies show that supplementing with vitamin D reduces risk for heart disease and diabetes, while some don’t.  The blanket conclusion from that research is “vitamin D does not prevent heart disease or diabetes”. I am not sure the answer is that simple.

Auto-immune disorders such as hypothyroidism or multiple sclerosis are skyrocketing in this country. Auto-immune disease-related deaths come only third to heart disease and cancer.[2]  Many diseases, such as heart disease and diabetes, are mediated by inflammation.  Vitamin D reduces auto-immunity and inflammation.[3]  A deficiency turns up auto-immunity and inflammation.
