WHAT IS VITAMIN D?

Vitamin D3 (Cholecalciferol): Vitamin D is a fat-soluble vitamin that helps maintain blood levels of calcium, by increasing absorption from food and reducing urinary calcium loss. Both functions help keep calcium in the body and therefore spare the calcium that is stored in bones. Vitamin D may also transfer calcium from the bone to the blood, which may actually weaken bones. Though the overall effect of vitamin D on the bones is complicated, some vitamin D is certainly necessary for healthy bones and teeth. Vitamin D is also produced by the human body during exposure to the ultraviolet rays of the sun. However, seasonal changes, latitude, time of day, cloud cover, smog, and sunscreen can all affect UV exposure. (www.nutritiondata.com/help/glossary#V)

Vitamin D deficiency is more common in northern latitudes, making vitamin D supplementation more important for residents of those areas. Vitamin D plays a role in immunity and blood cell formation and also helps cells differentiate—a process that may reduce the risk of cancer. From various other studies, researchers have hypothesized that vitamin D may protect people from multiple sclerosis, autoimmune arthritis, and juvenile diabetes. Vitamin D is also necessary to maintain adequate blood levels of insulin. Vitamin D receptors have been found in the pancreas, and some evidence suggests that supplements may increase insulin secretion for some people with adult-onset diabetes. (www.nutritiondata.com/help/glossary#V)

The high rate of natural production of vitamin D3 cholecalciferol (pronounced koh·luh·kal·sif·uh·rawl) in the skin is the single most important fact every person should know about vitamin D—a fact that has profound implications for the natural human condition.

Technically not a "vitamin," vitamin D is in a class by itself. Its metabolic product, calcitriol, is actually a secosteroid hormone that targets over 2000 genes (about 10% of the human genome) in the human body. Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more. (www.vitamindcouncil.org)

Many people are supplementing with 1,000 to 2,000 IU of vitamin D3 daily, but according to the Vitamin D Council that may not be enough. And blood testing is the only way to know for sure whether your regimen is appropriate. It’s hard to know exactly how much vitamin D your body is making from sun exposure. It depends on factors like what latitude you live at, your skin color and how much skin you expose for how long. And your needs may change according to the seasons, your age, your health and your weight. The Vitamin D Council suggests taking 5,000 IU of Vitamin D3 every day for three months, then get a 25-hydroxyvitamin D test. Optimal blood levels are between 50-80 ng/mL year-round. Adjust your dosage up or down according to your results. (www.vitamindcouncil.org)

A study published in the Journal of the American College of Cardiology indicated that people with low vitamin D levels might be twice as likely to suffer from a heart attack or stroke than those with higher vitamin D levels.

A University of California San Diego study found a 50 percent drop in colon cancer and a 30 percent decreased risk of ovarian and breast cancer with increased intake of vitamin D, which also reduced prostate cancer risk in men by 43 percent.

Recommended Daily Intake for Optimal Health

Dr. Joseph Mercola October 10 2009

http://articles.mercola.com/sites/articles/archive/2009/10/10/Vitamin-D-Experts-Reveal-the-Truth.aspx

Based on the most recent research, the current recommendation is 35 IU’s of vitamin D per pound of body weight.

So for a child weighing 40 pounds, the recommended average dose would be 1,400 IU’s daily, and for a 170-pound adult, the dose would be nearly 6,000 IU’s.

However, it’s important to realize that vitamin D requirements are highly individual, as your vitamin D status is dependent on numerous factors, such as the color of your skin, your location, and how much sunshine you’re exposed to on a regular basis.

So, although these recommendations may put you closer to the ballpark of what most people likely need, it is simply impossible to make a blanket recommendation that will cover everyone’s needs.

So how do you ensure optimal vitamin D levels for yourself, your child, and aging parents?

Blood Testing is the ONLY Reliable Way to Determine How Much Vitamin D You or Your Child Needs.

A blood test is extremely important!

Vitamin D May Lower Parkinson's Risk

Low Levels of Vitamin D Linked to Higher Risk of Parkinson’s Disease, Researchers Say

By Bill Hendrick
WebMD Health News

Reviewed by Laura J. Martin, MD

July 13, 2010 -- Higher levels of vitamin D may reduce the risk of developing Parkinson’s disease, a new study suggests.

The finding builds on previous research linking low vitamin D levels to Parkinson’s, and could mean that getting more sunlight and assuring an adequate dietary intake of vitamin D may help some people ward off the neurological disorder.

Paul Knekt, DPH, and colleagues at the National Institute for Health and Welfare in Helsinki, Finland, studied 3,173 Finnish men and women between the ages of 50 and 79 who did not have Parkinson’s when the research project began in 1978 to 1980.

Participants filled out questionnaires and were interviewed about socioeconomic and health backgrounds and underwent blood tests to be analyzed for vitamin D.

After 29 years, 50 of the participants had been diagnosed with Parkinson’s disease.

Participants who had the highest levels of serum vitamin D had a 67% lower risk of developing Parkinson’s than those in the lowest 25% of the group studied.

“Despite the overall low vitamin D levels in the study population, a dose-response relationship was found,” the authors write. “This study was carried out in Finland, an area with restricted sunlight exposure, and is thus based on a population with a continuously low vitamin D status.”

Therefore, the average serum vitamin D levels in the entire studied population were about 50% of what is considered optimal.

What Do You Lack? Probably Vitamin D

By JANE E. BRODY

Published: July 26, 2010

Vitamin D promises to be the most talked-about and written-about supplement of the decade. While studies continue to refine optimal blood levels and recommended dietary amounts, the fact remains that a huge part of the population — from robust newborns to the frail elderly, and many others in between — are deficient in this essential nutrient.

If the findings of existing clinical trials hold up in future research, the potential consequences of this deficiency are likely to go far beyond inadequate bone development and excessive bone loss that can result in falls and fractures. Every tissue in the body, including the brain, heart, muscles and immune system, has receptors for vitamin D, meaning that this nutrient is needed at proper levels for these tissues to function well.

Studies indicate that the effects of a vitamin D deficiency include an elevated risk of developing (and dying from) cancers of the colon, breast and prostate; high blood pressure and cardiovascular disease; osteoarthritis; and immune-system abnormalities that can result in infections and autoimmune disorders like multiple sclerosis, Type 1 diabetes and rheumatoid arthritis.

The Vitamin-D Debate

By Sanjay Gupta, M.D. Monday, May. 18, 2009

About 10 to 15 minutes spent outside in full sun will give a fair-skinned person dressed only in his skivvies 10,000 to 20,000 IUs. Turns out the debate about how much vitamin D we need has intensified over the past 10 years. One part of the discourse focuses on the growing body of research that points to numerous health benefits of the chemical (actually a hormone): it can help prevent rickets in children and severe bone loss in adults and potentially lowers the risk of multiple sclerosis, juvenile diabetes, cancer, heart disease, colds and influenza. Amid all this new evidence, the Institute of Medicine (IOM) has assembled a panel of experts to re-evaluate just how much vitamin D we really need and can safely tolerate. Current IOM recommendations, set in 1997, are 200 IUs a day from birth to age 50 and a bit more after that. The upper limit of safety, according to the institute, is 2,000 IUs daily--too much can lead to, among other things, nausea and kidney stones--yet some vitamin-D proponents are pushing for up to 4,000 IUs a day for adults.

Tired? Rundown? Check Your Vitamin D

Posted - 6/15/2010 at 10:31AM

TUCSON - Vitamin D is known as the sunshine vitamin, because sunlight exposure to skin is the best and only natural source for it. It's known to be essential for bone health, but research shows it's also crucial for fighting all kinds of diseases.

Todd Whitthorne, a health and wellness expert said, "We're finding that when we measure thousands of patients, the vast majority of them are low."

And Dr. Richard Honaker, a family practice physician, sees the same trends, "If you're low on vitamin D, your immune system does not function as well, or you're more susceptible to infections. There's a greater incidence of heart attacks and strokes in people that are vitamin D deficient versus people who are okay on their vitamin D levels."

How to Get the Most Out of Your Vitamin D Supplement

Triston Sanders - Medical Anchor

May 10, 2010

Your body may make better use of a vitamin D supplement if you take it with your largest meal.
Researchers at the Cleveland Clinic examined 17 patients with Vitamin D deficiency.
Over a period of two to three months, the patients were told to take Vitamin D supplements with the biggest meal they ate each day. This boosted the level of Vitamin D in their blood by an average of 56%, the researchers said.
The study was recently published in the Journal of Bone and Mineral Research.

Even on Formula, Babies Not Getting Enough Vitamin D.......

From: CNN.com

By Denise Mann, Health.com March 22, 2010 6:19 p.m. EDT

HOUSTON, TX - May 18, 2009 - Current recommendations for Vitamin D were called "grossly inadequate" at the American Association of Clinical Endocrinologists (AACE) 18th Annual Meeting & Clinical Congress. "National recommendations from the Food and Nutrition Board are 400 to 600 International Units (IU) a day," Neil Binkley, MD, an Associate Professor in Geriatrics and Endocrinology at the University of Wisconsin said. "That's simply not enough." "Experts recommend somewhere between 1500 to 2600 IU daily," Dr. Binkley said. "It's considered a very safe vitamin. One would need daily doses of 40,000 IU or higher before seeing negative side effects."

Dr. John Cannell MD is a psychiatrist at Atascadero State Hospital in California, a maximum security hospital for psychiatric patients. In 2005, an influenza A epidemic broke out in the hospital. One by one, each ward became infected as patients came down with chills, fever, cough, and severe body aches. Only one ward in the hospital remained free of infection — Dr. Cannell’s. Why was this so? His patients intermingled with patients from other wards and were not noticeably different in their age, health, or medical treatment. The only difference that could be discerned was that Dr. Cannell’s patients had been receiving a daily dose of 2000 IU of vitamin D for several months. That’s it. All of his patients took vitamin D and not one caught the flu! (Melanie Segala 07/15/2009)

Vitamin D Deficiency is Why You Get Flu!

Posted by Dr. Mercola | From: http://www.foodconsumer.org | March 25, 2010

http://www.foodconsumer.org/newsite/Nutrition/Vitamins/vitamin_d_deficiency_is_why_you_get_flu_2503100412.html

Taken from the above article:

Based on the latest research, many experts now agree you need about 35 IU’s of vitamin D per pound of body weight. This recommendation also includes children, the elderly and pregnant women.

However, keep in mind that vitamin D requirements are highly individual, as your vitamin D status is dependent on numerous factors, such as the color of your skin, your location, and how much sunshine you’re exposed to on a regular basis. So, although these recommendations may put you closer to the ballpark of what most people likely need, it is simply impossible to make a blanket recommendation that will cover everyone’s needs.

The only way to determine your optimal is to get your blood tested. Ideally, you’ll want to maintain a vitamin D level of 50-65 ng/ml year-round.

Vitamin D More Effective Than Previously Known

Editorial by Bill Faloon of Life Extension Foundation:

A large number of new vitamin D studies have appeared in the scientific literature since I wrote my plea to the federal government. These studies don’t just confirm what we knew 16 months ago—they show that optimizing vitamin D intake will save even more lives than what we projected.

For instance, a study published in June 2008 showed that men with low vitamin D levels suffer 2.42 times more heart attacks. Now look what this means in actual body counts.

Each year, about 157,000 Americans die from coronary artery disease-related heart attacks.4 Based on this most recent study, if every American optimized their vitamin D status, the number of deaths prevented from this kind of heart attack would be 92,500.

To put the number of lives saved in context, tens of millions of dollars are being spent to advertise that Lipitor® reduces heart attacks by 37%. This is certainly a decent number, but not when compared with how many lives could be saved by vitamin D. According to the latest study, men with the higher vitamin D levels had a 142% reduction in heart attacks.

What Is Vitamin D Deficiency Anyway...

www.easy-immune-health.com

Naturally, this would be the first question to answer before we can actually TREAT vitamin D deficiency. I’ve answered this question on the Normal Vitamin D Level page, and you should go there right now to find out what your vitamin D level SHOULD be- and the answer is NOT the same answer that is on your lab sheet.

The lab sheet does not provide you with what the ‘optimal’ Vitamin D Levels are. And many researchers believe that the low level on your lab sheet is WAY too low and should be considered “vitamin D Insufficiency” rather than ‘Low Normal Vitamin D Level’.

Despite the argument for D3 that was made, the D2 will certainly not harm you and will be effective at correcting your deficiency. If, however, you read the argument and prefer not to take D2 (a good choice), then going out and buying Vitamin D Supplements in the form of Vitamin D3 is really the best choice.

Either way, you SHOULD be using Vitamin D3 for your Daily Vitamin D Requirements after your regimen of Vitamin D Deficiency Treatment is finished.

The Right KIND of Vitamin D Supplements

Once you find out your Vitamin D Level, you need to decide what KIND of Vitamin D Supplements to take for your Vitamin D Deficiency Treatment. The BEST vitamin D supplements are those containing Vitamin D3- also known as Cholecalciferol, and you can see the Vitamin D 2 vs Vitamin D3 argument on that page. But if you are being followed by a doctor for your Vitamin D Deficiency Treatment, it’s likely that you will get a prescription for Vitamin d 2- also called ergocalciferol.

Vitamin D Deficiency Treatment Protocols

It is becoming more and more apparent that the Vitamin D Dosage required for a normal vitamin D level is MUCH higher than you might think. In fact, it is such a large amount that many doctors just won’t give enough to actually correct the deficiency- although this is changing as doctors are becoming more experienced with vitamin D deficiency treatment.

Vitamin D Deficiency Treatment Protocols
	Most Adults	Most Children aged 1 to 18
Dr. Michael Holick	50,000 IU's D2 once/week for 8 weeks Repeat if Level Less than 30 ng/ml	50,000 IU's D2 once/week for 8 weeks
Leventis, P.1; Kiely, P. D. W	300,000 IU Vitamin D3 Orally 3 times per year
The Use of Vitamin D in Clinical Practice	Up to 10,000 IU's per day
Vitamin D Council	Enough to get the Vitamin D Level Between 50 -80 ng/ml	Enough to get the Vitamin D Level Between 50 -80 ng/ml

If you have even mild Vitamin D Deficiency, it is likely that you will need to be taking approximately 50,000 IU’s per week for 4 to 12 weeks.

If you have SEVERE deficiency, then you may need to be taking Vitamin D Supplements as high as 50,000 IU’s per DAY for a month or even two months until getting a repeat Vitamin D Serum Level. Some doctors may even give a Vitamin D injection of 600,000 IU’s once a month for several months until your Vitamin D Level gets up to the ‘Optimal Range’ of 40 to 80 ng/ml.

While these doses may seem VERY high to those who are not used to them, they are all acceptable dosages for Vitamin D Deficiency Treatment. There is little risk of a Vitamin D Overdose as long as you are getting your Vitamin D Level checked every few months of treatment and then at least every year thereafter. In fact, there has NEVER been a documented case of Vitamin D Overdose on 10,000 IU’s per day or less, in an adult, even when taken for several years!

50,000 IU's is equivalent to approximately 1.25 mg

As a rule of thumb, 1,000 IU's will raise 25(OH)D levels by about 10 ng/mL

http://www.vitamindcouncil.org/newsletter/2008-may.shtml

According to the Vitamin D Council

The Dosage Recommended

John Jacob Cannell MD Executive Director 2008.10.01

If you use suntan parlors once a week or if you live in Florida and sunbathe once a week, year-round, do nothing. However, if you have little UVB exposure, my advice is as follows: healthy children under the age of 1 years should take 1,000 IU vitamin D3 per day—over the age of 1, 1,000 IU vitamin D3 per every 25 pounds of body weight per day. Well adults and adolescents should take 5,000 IU vitamin D3 per day. Around 2–3 months later have a 25-hydroxyvitamin D blood test, either through ZRT or your doctor.

Start supplementing with the vitamin D before you have the blood test. Then adjust your dose so your 25(OH)D level is between 50–80 ng/ml (125–200 nmol/L), summer and winter. But remember, these are conservative dosage recommendations. Most people who avoid the sun—and virtually all dark-skinned people—will have to increase their dose once they find their blood level is still low, even after two months of the above dosage, especially in the winter. Some people may feel more comfortable ordering the blood test before they start adequate doses of vitamin D. We understand. Test as often as you feel the need to, just remember, no one can get toxic on the doses recommended above and some people will need even more.
