A Japanese study is the first clinical trial to test vitamin D against flu; children who took vitamin D were less likely to get one kind of flu!

Last year, American researchers who analyzed data from a survey of nearly 19,000 Americans (NHANES III) found that those with the lowest blood levels of vitamin D reported having significantly more recent colds or cases of the flu.

A Japanese team has just published the results of the very first controlled human trial designed to test vitamin D’s power to prevent the flu.

And the outcomes were encouraging: “This study suggests that vitamin D3 supplementation during the winter may reduce the incidence of influenza A.

This study among schoolchildren included a sharp drop in asthma attacks among the kids assigned to take vitamin D and also showed that kids taking vitamin D were 63% less likely to have developed influenza type A.

Bottom line is start using Vitamin D on a daily basis to help your body’s immune system.




Low Vitamin D causes heart problems

15 09 2011

XCAP has a vitamin D product called Vita D (http://www.xcap.tv/VitaD_Home.asp).

Vitamin D levels were measured in ninety patients with chronic heart failure and thirty-one control patients without heart disease.
Vitamin D levels were much lower in those with heart failure than controls.

Specifically, an astounding 98% of the patients with heart failure had a vitamin D deficiency defined by vitamin D levels below 75 nmol/L and severe deficiency (less than 25 nmol/L) occurred in 67% of the patients.

These results mimic observations seen in animal studies that demonstrated vitamin D supplementation can prevent heart failure in rats. (Nutrition, Metabolism and Cardiovascular Disease, November 2010)

Low Vitamin D Hurts Pro Athletes

Xtreme Couture Athletic Pharmaceuticals or (XCAP) helps pro athletes with our VitaD product.

>>>>>>>>>>>>>>>>> Below is a study of the benefits on NFL players.

The authors tested the vitamin D blood levels of 89 players from the NFL’s New York Giants during the spring of 2010.

Their average age was 25, and the group included 31 white and 58 black (African American) players.

According to lead researcher Michael Shindle, M.D., “Eighty percent of the football team we studied had vitamin D insufficiency. African American players and players who suffered muscle injuries had significantly lower levels.” (AAOSM 2011)

Sixteen of the 89 tested players had spent time on the disabled list due to muscle injuries.

The average vitamin D level among these previously muscle-injured players was 19.9 nanograms per milliliter (ng/mL) … Levels below 20 are considered by most experts to be very low.

The 73 players with no history of time lost due to a muscle injury had an average vitamin D level of 24.7 ng/mL – which most experts would call insufficient or deficient – with their levels ranging from 9 ng/mL (very deficient) to 46 ng/mL (lower end of the optimal range).

These were the overall results of the blood tests on the 89 New York Giants players:

  • Twenty-seven
    (30.3%) players had levels considered deficient (less than 20 ng/mL).
  • Forty-five
    (50.6%) players had levels considered insufficient (20 to 31.9 ng/mL).
  • Seventeen
    players (19.1%) had levels considered normal (32 ng/mL or higher).

Based on the growing evidence that 20 ng/mL is too low to ensure adequate health, many vitamin D testing laboratories have raised their definition of a “normal” blood level to 30 ng/ml or more.  Many anti-aging doctors consider from 65 to 100 ng/ml to be optimal.

For example, Boston University’s Michael Holick, Ph.D., M.D. – a leading researcher and author of The Vitamin D Solution – says the optimal level is 40 to 60 ng/mL and that it takes 3,000 IU per day of dietary vitamin D to achieve and maintain that range.

Co-author Scott Rodeo, M.D., urged team physicians to heed the implications of their findings: “Screening and treatment of vitamin D insufficiency in professional athletes may be a simple way to help prevent injuries.” (AAOSM 2011)

XCAP’s product Vita D is the best form of vitamin D on the market today.  One drop is equal to 2000 iu.

Vitamin D improves Testosterone

25 01 2011

I have been saying for several years that when I give patients Vitamin D, it improves their hormone levels.  Now, here is some research to back it up.  Dr. John Fitzgerald, Blood Doc John

Effect of Vitamin D Supplementation on Testosterone Levels in Men.

Department of Internal Medicine, Division of Endocrinology and Metabolism, Medical University of Graz, Austria.


The male reproductive tract has been identified as a target tissue for vitamin D, and previous data suggest an association of 25-hydroxyvitamin D [25(OH)D] with testosterone levels in men.

We therefore aimed to evaluate whether vitamin D supplementation influences testosterone levels in men.

Healthy overweight men undergoing a weight reduction program who participated in a randomized controlled trial were analyzed for testosterone levels. The entire study included 200 nondiabetic subjects, of whom 165 participants (54 men) completed the trial.

Participants received either 3 332 IU vitamin D daily for 1 year or placebo. Initial 25(OH)D concentrations were in the deficiency range (<50 nmol/l) and testosterone values were at the lower end of the reference range (9.09-55.28 nmol/l for males aged 20-49 years) in both groups. Mean circulating 25(OH)D concentrations increased significantly by 53.5 nmol/l in the vitamin D group, but remained almost constant in the placebo group.

Compared to baseline values, a significant increase in total testosterone levels (from 10.7±3.9 nmol/l to 13.4±4.7 nmol/l; p<0.001), bioactive testosterone (from 5.21±1.87 nmol/l to 6.25±2.01 nmol/l; p=0.001), and free testosterone levels (from 0.222±0.080 nmol/l to 0.267±0.087 nmol/l; p=0.001) were observed in the vitamin D supplemented group.

By contrast, there was no significant change in any testosterone measure in the placebo group. Our results suggest that vitamin D supplementation might increase testosterone levels.

Flu and Allergies info for you

15 12 2010

I copied this excerpt about the Flu and Allergies that was in a newsletter that goes out to doctors.  I thought you would find it informative.

Starts Here:

I am reminded of a story Dr. John Cannell told at the IAACN a few years ago. Dr. Cannell is a physician at a psychiatric unit in California. Knowing the research on vitamin D and how it facilitates a healthy immune system, he placed a group of his patients on optimal levels of vitamin D.

That year the flu was unusually virulent and just about everyone in the hospital got sick… nurses, support staff and patients in other areas of the hospital. Everyone, that is, except his group of vitamin D sufficient patients. His patients were not affected by the flu except for minor sniffles.

It was an amazing demonstration of prevention. However, he is quick to add that vitamin D is not the cure for the flu. Dr. Cannell recommends everyone get tested for vitamin D and shoot for the 50-70 ng/ml range to optimize health and assure that sufficient levels are available to foster healthy genetic expression.

Of the 20,000 genes identified, researchers say we need vitamin D for approximately 3,000 of them to function efficiently. As a side note, sometimes vitamin D levels seem to be resistive getting into optimal ranges. In every case, whenever I’ve recommended:

Bio-D-Mulsion Forte (Vita D) to a doctor or patient, they have been successful in bringing vitamin D to optimal status.  (The reason Vita D absorbs so much better than other products is that it is the smallest available emulsion and absorbs lymphatically)

Vitamin D isn’t the only nutrient star. It may be the super star in recent years, but remember, the white blood cells need folic acid, B12, and zinc to name a few to do battle effectively.

The zinc “taste test” to assess for zinc is a test that can be done by your staff on every patient for pennies. Zinc is needed for well over 100 enzymes reactions. We need zinc to make hydrochloric acid and important enzymes like carbonic anhydrase and the metal transporting enzyme metallothionein.

Let me re-emphasize. Having these enzymatic reactions working properly can have far reaching effects ranging from pain reduction to reducing depression.

A study published in “Agents and Actions,” indicated that high doses of zinc would help to control the release of histamine from basophil and mast cells.  (In other words, zinc may help your allergies)

Zinc may be a key factor with your allergy sensitive patients as well. Helping your patients attain sufficient zinc levels in the fall could make the difference in how they feel when spring allergy season arrives. So that little zinc taste test goes far beyond preventing or reducing flu symptoms.

In talking to clinicians, some of you were discouraged with the zinc taste test as you didn’t see appropriate changes. According to the original research on zinc sulfate, make sure you keep your patients on 6 or more teaspoons a day of the liquid form until they can taste it. (Then reduce dose to once per day or once every other day).
