Vitamin D Health Benefits

Latest Vitamin D Studies Find Even More Health Benefits

Alcat logoIn their latest vitamin D report, the Institute of Medicine's Food and Nutrition Board (FNB) claims the only evidence for the benefit of vitamin D they could document was the improvement of bone health.

How they could come to this conclusion is truly beyond belief, because there are literally hundreds if not thousands of studies showing that it benefits dozens if not hundreds of clinical conditions!

Based on their limited findings, the FNB's updated recommended daily allowance (RDA) for vitamin D is as follows:

  • Infants 0-12 months 0 IU/day
  • 1-18 years 600 IU/day
  • 19-50 600 IU/day
  • 51-70 600 IU/day
  • Over 70 years old 800 IU/day
  • Pregnant women aged 14-50 600 IU/day


Cholecalciferol Vitamin D3 is a hormone with nuclear receptors in the same super family as testosterone, estrogens and glucocorticoids. These receptors are in the same sub family as those for thyroid hormone. When these ligands bind to these nuclear receptors,a conformational change happens that up-regulates gene expression. As we age (after 26 years old) vitamin D3 level drops.

How Much Vitamin D3 Should You Take?:

  • There is no disease prevention when Vitamin D3 levels are less than 40-60 ng/ml !!
  • Vitamin D is needed to prevent influenza, heart- or liver-disease, respiratory infections, cancer, or any of the numerous diseases that have a clearly documented link to vitamin D deficiency. [see list below]
  • Higher Vitamin D Levels ARE Beneficial to Your Health
  • You are the least likely to get disease when your vitamin D levels are 80-90 ng/ml, with 100 being the high limit of normal
  • Women who are pregnant need 7,000-8,000 IU’s /day of D3
  • Everyone is different, but generally 5,000 IU/day is a good dose for most; some need less some need more.
  • Between 40-50 ng/ml, you only get a 5ng/ml rise for each 1,000 IU Vit D3. So, it would take more than 6,000 IU/day to get 90-95% of the population above 40 ng/ml


Diseases and Conditions Linked to Vitamin D3 Deficiency:

1. Parkinson’s Disease - Two new studies suggest that older people who are deficient in Vitamin D may be more likely to develop the neurological disorder. The first study was directed by Paul Knekt of the Finnish Institute for Health and Welfare. David Llewellyn of Italy’s Exeter University spearheaded the second study, which was published in the Archives of Internal Medicine. Source

2. Asthma - A new study conducted by the Harvard Medical School in Boston found that children low in Vitamin D3 were more likely to suffer an asthma attack requiring hospitalization than were children with healthy levels of the vitamin. Source

3. Chronic Pain - Two studies – one by Dr. Greg Plotnikoff, the other by the Mayo Clinic – appear to show a link between Vitamin D Deficiency and chronic pain. Source

4. Childhood Obesity - A study published in the American Journal of Clinical Nutrition suggests that Vitamin D deficient children are likely to have a higher Body Mass Index (BMI) than their better-nourished schoolmates. Source

5. Osteoporosis in Patients with IBD - A study by the American College of Gastroenterology indicates that Vitamin D deficient patients with IBD (Irritable Bowel Disease) are at a greater risk of developing osteoporosis, osteopenia and an overall higher rate of abnormal bone density. Source

6. Autoimmune Disorders - A study published in Genome Research indicates that people with insufficient Vitamin D are more susceptible to autoimmune diseases such as multiple sclerosis, type 1 diabetes, and Crohn’s disease. Source

7. Arterial Stiffness – The Endocrine Society published a study this past summer linking Vitamin D deficiency to arterial stiffness in black teens. Source

8. Diabetes and Metabolic Syndrome – Researchers from Johns Hopkins University presented a study at the Endocrine Society’s annual meeting establishing a link between Vitamin D Deficiency and Diabetes and Metabolic Syndrome, which is the medical precursor to diabetes. Source

9. Cancer, Heart Disease and More – The following study appearing in the American Journal of Clinical Nutrition establishes the preventive benefits of Vitamin D3 with regard to various forms of cancer, heart disease and numerous others. Source

10. Rickets – This one has long-been established as fact by the medical and scientific communities, so I therefore feel no need to include specifics or cite sources. The link has been firmly established and repeatedly confirmed.

11. Inflammation – A 2009 study published in the Archives of Internal Medicine confirmed a link between Vitamin D Deficiency in otherwise healthy women and increased inflammation. Source

12. Autism - There is an increasing body of evidence that Vitamin D Deficiency is a contributing factor to autism. Dr. John Cannell, a psychiatrist and prominent vitamin D advocate, says flagging levels of the vitamin in pregnant women and young children could be the elusive factor explaining the rising rate of autism. Source

13. ADHD - Recent studies from the past several years increasingly point to a relationship between low levels of Vitamin D3 and an aggravation/intensification of the symptoms of ADD and ADHD. Source

14. Influenza & Swine Flu - Research presented by John Cannell, MD of the Vitamin D Council showed that Vitamin D3 is protective against seasonal flu. Further research performed by Norris Glick, MD and Ellie Campbell, DO, showed that Vitamin D3 helps prevent H1N1 Flu. Further, Dr. John Cannell showed that Vitamin D3 deficiency activates the influenza virus (the Flu). Vitamin D3 and Influenza

15. Fibromyalgia - A study published in the Journal of Pakistan Medical Association determined that Vitamin D3 deficiency is frequently seen in patients diagnosed with fibromyalgia and nonspecific musculoskeletal pain. Source

16. Hypertension & High Cholesterol - Evidence from numerous clinical and epidemiological studies have shown that increased dosages of Vitamin D3 can help lower blood pressure and cholesterol in patients deficient in the nutrient. Source

17. Depression - A scientific link between low Vitamin D3 levels and depression has been established following several recent studies confirming the relationship. According to one such study by scientists at Georgia State University: “The likelihood of having depression in persons with vitamin D deficiency is significantly higher compared to those with vitamin D sufficiency. Early diagnosis and intervention are paramount because coexistence of vitamin D deficiency and depression has serious negative consequences on health.” Source

18. Chronic Fatigue Syndrome - Vitamin D deficiency is closely associated with the chronic fatigue in patients with traumatic brain injury. Source

19. Tooth Decay - There is strong evidence indicating a relationship linking Vitamin D Deficiency to cavities and tooth decay. Dozens of studies were conducted in the 1930s and 1940s on this very subject. More than 90% of those studies concluded that supplementing children with vitamin D prevents cavities.

20. Lung Transplant Rejection - Vitamin D deficiency is associated with a significant increase in lung transplant rejection, according to research conducted at Loyola University Health System (LUHS). Source

Please keep in mind that this is only a partial list of the myriad of diseases and adverse conditions that are either caused in part by or aggravated by Vitamin D Deficiency, or that can largely be prevented with adequate sun exposure and/or supplemental intake. Check back as I will be posting a follow-up article sometime in the near future listing even more diseases for which this nutritional shortage is a contributing factor.

*** REMEMBER if you have CANDIDA your body is not capable or absorbing Vitamin D3. This is WHY I recommend and prescribe the Vitamin D3 Spray, it does absorb, almost as fast and effectively as an IV!

Reasons for taking Vitamin D3

by Dr. John J. Cannelll, founder of the Vitamin D Council, leader in Vitamin D metabolism

5,000 IUs of Vitamin D3 in every dose

Most Americans DO NOT get enough sunshine, the most natural source of Vitamin D

Vitamin D is crucial for optimal Calcium metabolism

Provides dynamic Bone and Muscle Support

Vitamin D provides natural Immune Support.

Supports Heart and Cardiovascular Health

Increases risk of developing macular degeneration and cataracts

Low Vitamin D levels exacerbate Parkinsonism


Q: What is the right vitamin D level?
A: Ideally 60-90 ng/ml.

Vitamin D3 Mouth Spray is great for those allergic to Gluten or gladin and suffering from Candida. The cell wall of Candida has the same amino acid sequence as gluten, so when you eat gluten in grains, it activates an immune reaction to Candida in the gut which causes gut inflammation and food allergies which cause more gut inflammation so that the absorption of Vitamin D is markedly decreased, which leads to decreased bone mass. So Vitamin D supplementation is very important at about 5000 units per day.

Dr. John Cannell, founder of the Vitamin D Council, says:

"It turns out that the higher your vitamin D level the less likely it is for that [macular degeneration] to happen. There is even a cross-sectional study that indicates that the lower your vitamin D level the more likely you are to get cataracts (and one of the reasons you've always been told to stay out of the sun is because you'll get cataracts)."

There is also an interesting new paper about Parkinsonism that suggests that low vitamin D levels exacerbate the disease. "So if you know of anyone with Parkinsonism make sure their vitamin D levels are in the high range; higher than normal, between 50-80 ng/ml," Cannell suggests.
This would also hold true for other chronic neurological diseases, such as Alzheimer's.
"That's a really important point," Cannell says.

"People are asking me, "What's the right vitamin D level?" If you're otherwise perfectly healthy, then a level of around 50 is fine… But many people who have heart disease, Parkinsonism, Alzheimer's, emphysema, or cancer… It's my opinion that [those] people should get their levels up into the high range of normal.

The rationale for that is that there are a number of studies with cancer now that show that the blood level of vitamin D you have at the time you're diagnosed with cancer predicts how long you're going to live. That is, high vitamin D levels at the time of diagnosis prolongs life.

… If you're sick, you want to keep your levels at 80-90 ng/ml."
