Guest guest Posted August 25, 2007 Report Share Posted August 25, 2007 More specifically, it is the active form of vit. D Vit D3 that you need. 2000 U at least needed. A study of women ages 55 and over showed a 60% decrease in cancer incidence by taking vit. D 77% decrease if you excluded women that already had cancer early in the study. These women excluded did not have time to benefit from vit D Quote Link to comment Share on other sites More sharing options...

Guest guest Posted January 9, 2008 Report Share Posted January 9, 2008 Vern, Any " megadoses " of Vitamins are not recommended. The FDA guidelines for " D " in International Units (IU) are: 200 IU, until age 50 (One cup of vitamin D-fortified milk or juice provides 50 IU of vitamin D.) 400 IU, age 51-70 (Multivitamins typically provide 400 IU of vitamin D.) 600 IU, over age 70 Hope this helps.

Guest guest Posted January 10, 2008 Report Share Posted January 10, 2008 Vern, Assuming that you are under age 50, the 200 mg of " D " should be OK. Considering that one cup of vitamin D-fortified milk or juice provides 50 IU of vitamin D it should be easier to get the 200 mg through nutrition instead of supplements. You may want to consult your physician about this as there's no point in taking supplements if your diet includes what you need. Sunlight is also a source of " D " .

Guest guest Posted January 10, 2008 Report Share Posted January 10, 2008 I don't drink much if any milk and not much if any juice. I live in the north so we don't get much sun in the winter. I already take a lot of supplements as it is, I just wasn't sure if D was bad news or not at a low IU amount. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 10, 2008 Report Share Posted January 10, 2008 Thanks for the info...I have heard very recently that the levels of recommended daily Vit D are being revised upwards by the medical community ... to closer to 600 - 1000 IU/day . Perhaps others, too, have heard something in this regard, too. Sue Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 11, 2008 Report Share Posted January 11, 2008 My Doctor recommended that I take 800 IU per day. She actually said that unless you are outside (naked) at 12 noon everyday you are not likely to get enough vit.D from the sun! Assuming there is sun (especially in a Canadian Winter).

Guest guest Posted January 11, 2008 Report Share Posted January 11, 2008 Thanks for posting. I keep reading many lyme sufferers have low levels of Vit D (including myself). I always supplemented it plus took sun whenever I could (still doing that). I wonder if lyme depletes us of Vit D in a similar way it depletes us of magnesium.... Vit D is one of the supplements that tested very long for me, together with magnesium. I can tell I take these almost without interruption for about 2 years (since I started seriously my lyme treatment).

Guest guest Posted January 11, 2008 Report Share Posted January 11, 2008 There've been reports indicating that too little Vit D allows certain cancers to grow. They found this out because so many people were avoiding the sun when they said it causes skin cancer. Now a certain amount of VitD is said to prevent certain cancers. ellen > > Thanks for posting. > > I keep reading many lyme sufferers have low levels of Vit D (including > myself).

Guest guest Posted January 17, 2008 Report Share Posted January 17, 2008 It may be the lack of sunlight during the winter months up in Canada that is affecting him and why the sunlight in mexico seemed to help so much.

Guest guest Posted January 20, 2008 Report Share Posted January 20, 2008 Uh oh -- I'm just catching up on e-mails and saw this. I've been taking 1000 IU of Vitamin D/day for a year and a half. What would any symptoms be of taking too much? I don't feel any different -- in fact I never feel a difference no matter what vitamins I take. Thanks for any info. JoAnn N.

Guest guest Posted January 25, 2008 Report Share Posted January 25, 2008 Hi Roni, Well, you have a lot of company! Both my wife and I were extremely deficient in vitamin D3. IMO you take far too little, it takes 4,000iu for my wife (5'0 " and petite) to make it to 50ng blood level. It takes over 6,000iu daily for me. Both of our children (aged 11 and 17) get 2,400iu daily. None of us have had a cold this season, as one of the wonderful things vitamin D does is taking responsibly for managing much of the immune system (yea, I have links AND studies!). I would start taking more and getting your blood levels checked after a couple of months. If it were me I would start taking 10,000iu daily for about 7-10 days, then back off to 4,000iu daily FOREVER! Dr. of Milwaukee (internal medicine and cardiology) tests everyone of his patients, 95% are deficient, so have zero levels of circulating vitamin D. With vitamin D, everyone is like a snowflake...some only need 2,000iu daily, some need in the range of 10,000-12,000iu daily to reach 50ng, so BLOOD TESTING IS CRITICAL! Neil > > I just discovered that I am vitamin D deficient, and I take well over 1000 IU of vitamind D > a day. However, I am allergic to the sun, so I never go into the sun for more than a minute > or two. > > Here's a site: > Roni > > Diet, nutrition & weight loss > Preventing vitamin D deficiency — the new breakthrough? by Marcelle Pick, OB/GYN NP > > I just returned from a conference where everyone was discussing vitamin D. It's been a hot topic in both conventional and alternative medicine lately because vitamin D deficiency seems to be related to so many health concerns: depression, heart disease and stroke, cancer, osteoporosis, parathyroid problems, immune function — even weight loss. > Practitioners from both sides of the aisle are seeing more cases of vitamin D deficiency — one colleague reported that 85–90% of his patients don't get enough D. And that's consistent with what we see at Women to Women. > How can this be happening? And what should you do about it for you and your family? The answer isn't as simple as drinking more fortified milk. > We've been testing and treating patients for vitamin D deficiencies for several years, and I know there are effective, natural strategies that work in most cases. In others, vitamin D therapy is needed and can bring wonderful results. So let's explore vitamin D's role in your health and how to determine what you should do. > What does vitamin D do for the body? This essential nutrient is called a vitamin, but vitamin D is actually a precursor hormone — the building block of a powerful steroid hormone in your body called calcitriol. It's been known for many years that vitamin D is critical to the health of our bones and teeth, but our deeper insight into D's true role in our health is quite new. > Vitamin D works in concert with other nutrients and hormones in your body to support healthy bone renewal — the ongoing process of mineralization and demineralization that when awry shows up as rickets in children and osteomalacia ( " soft bones " ) in adults. > Researchers are discovering that D also promotes normal cell growth and differentiation throughout the body, a key factor in maintaining hormonal balance and a healthy immune system. It appears that calcitriol actually becomes part of the physical composition of cells, assisting in the buildup and breakdown of healthy tissue — in other words, the process that keeps you well. > What's more, evidence from studies that track the prevalence of disease by geography and nationality shows links between vitamin D deficiency and obesity, insulin resistance, heart disease, certain cancers, and depression. I test all of my patients and have been surprised to find that 85% come up with a vitamin D deficiency. > Your body can't create vitamin D on its own. Instead, it's designed to make it through sun exposure. In theory, you can make an ample supply of vitamin D with as little as a couple of hours per week in the sun. You can also ingest D through food, especially eggs and certain fish. So vitamin D deficiency should be an easy problem to solve, right? But the truth is we're just not getting enough. > Vitamin D requirements The growing awareness of how much our bodies rely on vitamin D has raised concern that the dietary recommended daily intake values (DRI's) are obsolete — 200 IU (International Units) a day for adults 19–50 years old, 400 IU for those 51–70, and 600 IU for those over 70. Many experts now agree that the DRI's for vitamin D are way too low, particularly for people who don't get sufficient sun exposure. It's also important to note that we lose some of our ability to absorb vitamin D as we age. Some studies have shown that adults can metabolize up to 10,000 IU per day without side effects. The European Union's Scientific Committee on Food lists 2000 IU per day as the safety cut-off, as does the US Food and Nutrition Board, but until we have more complete information on who needs how much, general wisdom has put the tolerable intake level at 1000 IU per day. > Vitamin D supplementation appears beneficial throughout our lifespan, from in utero to advanced age. A recent long-term study indicates that we are at less risk of developing osteoporosis later in life if our mothers had adequate stores on board while pregnant. Another age group needing ample vitamin D is teenage girls living in northern climates who cannot get enough sunlight to make enough vitamin D naturally. Optimal bone growth and accumulation during puberty may be a factor in preventing osteoporosis later on in life, and a new daily recommendation for teenage girls of 400-600 IU — up from 200 IU — would be wise, particularly in winter. > The elderly, who are at increased risk of falls and fractures, also stand to benefit. Some studies in the US indicate that supplementation with vitamin D and calcium significantly reduces bone loss and incidence of nonvertebral fractures in women 65 and over. Even in sunny Australia, a two-year study conducted among the elderly showed that supplementation with vitamin D reduced incidence of falls and fractures. Yet all these studies have their limitations, and it's a misconception to think that supplements alone are enough to protect your bones for life. > Another consideration is that not all forms of vitamin D are the same — some are more usable (bioavailable). Our bodies can naturally synthesize more than 20,000 IU of vitamin D in just 20 minutes of sun exposure without ill effect. That's because we have a natural check-and-balance mechanism that shuts off the synthesis when we get enough. This doesn't happen when we eat sources of vitamin D — the same 20,000 IU of vitamin D taken as an oral supplement could be toxic. > Most milk suppliers fortify their products with vitamin D in the form of ergocalciferol (also called D2). Some orange juice makers are doing the same, and like many food fads, you can soon expect to see lots of other products claiming to be good for you because they're fortified with vitamin D. While the amount in these beverages is enough to ward off malnutrition, you'd have to drink four or five glasses a day to reach optimal levels; that's just too much milk or juice for most adults. > But let's not write off vitamin D-fortified foods altogether. It's interesting that a bakery here in the US had to test their new vitamin D bread in Europe because of the high amount of vitamin D it contained. The bread also contained calcium carbonate and was reported to increase lumbar bone mineral density in the elderly patients consuming it. > The bottom line is, we still don't really understand the mechanism behind vitamin D — we just know our bodies rely on a certain amount and that many of us aren't getting enough. The truth is that adequate levels are probably highly individualized and depend on a variety of factors. To know whether you're D–deficient, you need to get a blood test from your healthcare practitioner. > Why the lack of vitamin D? Awareness of vitamin D first took center stage in the early part of the 20th century, although it was described in medical writings as early as the 17th century. Children with vitamin D deficiency developed rickets, a condition in which the body fails to mineralize bone. This led to a movement to fortify milk and cereal with vitamin D. By the 1960's, rickets had become a relatively rare disease. > As we now know, sun exposure is critical to sufficient vitamin D. Until modern times, human beings spent a great deal of time outdoors. The origin of our species was subtropical, meaning we naturally got enough sun exposure to generate vitamin D. But as Homo sapiens migrated to less temperate climes this changed. The shift from an agrarian-based society to an increasingly industrial society also meant less time in the sun. > Today many of us work in sealed buildings with glazed windows, and we wear sunblock and drive everywhere in cars instead of walking outdoors. Any sunblock with an SPF above 8 will block the UV rays necessary for vitamin D conversion. > If you live in a region above latitude 40 (a horizontal line that runs from just below New York City west to northern California), then the sun is only strong enough to trigger the vitamin D conversion between May and September. This means that a large percentage of the population is at risk much of the year for vitamin D deficiency. On the other hand, don't just assume that because you live in New England, for example, that you are deficient. You really need to see your practitioner and have your vitamin D levels tested before upping your supplemental dose. > Vitamin D deficiency symptoms Vitamin D deficiency may be characterized by muscle pain, weak bones/fractures, low energy and fatigue, lowered immunity, depression and mood swings, and sleep irregularities. Women with renal problems or intestinal concerns (such as IBS or Crohn's disease) may be vitamin D deficient because they can neither absorb nor adequately convert the nutrient. > Vitamin D, menopause and osteoporosis As we age, our bodies slowly lose the ability to mobilize vitamin D, a process that lowers our calcium absorption rates. This creates a higher risk of osteoporosis, particularly in post-menopausal women. > We're not sure how sex hormones affect vitamin D conversion, but women seem to have a harder time stimulating the mechanism that builds bone tissue when their estrogen levels are reduced. > Calcium is clearly an important co-factor to vitamin D, and may lose efficacy if vitamin D is deficient or estrogen levels are low, as vitamin D appears to be the more critical factor in bone health. A recent study by scientists at the University of Massachusetts found that a diet rich in calcium and vitamin D can help control some symptoms of PMS, such as tearfulness, anxiety, and irritability. > What does this mean? No one knows for sure, but it is more evidence that all the systems of the body are connected and we can't look for easy answers in one place. > Vitamin D and weight loss I'm sure many of you have seen the new " diet with dairy " ads launched by the American Dairy Council. Some studies have shown that weight loss does occur with an increase in calcium intake, while others appear to refute this. Since vitamin D is directly involved in calcium absorption, it stands to reason that vitamin D is also a factor in how the body regulates weight. > Moreover, people who have a reduced capacity to mobilize vitamin D often weigh more and have more body fat than those with full capacity. In the past 20 years multiple studies have shown a correlation between higher blood levels of vitamin D and leaner body mass. > Again, vitamin D seems to be very important in regulating our weight, but we don't yet understand the mechanism involved or how it relates to our environment and individual biochemistry. Still, there may be a correlation between rising rates of obesity and vitamin D deficiency. If you are having difficulty with weight gain — or can't keep the pounds off once you lose them — you may want to have your vitamin D levels checked by your healthcare practitioner. > Vitamin D and cancer Evidence is mounting that vitamin D may protect against some cancers, particularly breast cancer, prostate cancer, and colorectal cancers. In fact, over 60 years of research have shown vitamin D supplementation or sunlight-induced vitamin D conversion to be associated with lower incidence of cancers. > There is also a higher incidence of breast cancer in northern climates, but whether that is associated with lower levels of vitamin D is still speculation. Vitamin D deficiency most certainly affects your immune system because calcitriol actually helps regulate cell division, so adequate levels may help sustain normal cell growth. And stress and other physiological markers can disrupt the function of vitamin D receptors, among others, making us more susceptible to unusual cell activity. > Vitamin D and depression Another area of vitamin D research is its relationship to depression. Seasonal affective disorder, or SAD, is a situational mood disorder brought on by decreasing daylight in the winter months (for more see our article on antidepressants). High doses of vitamin D during these months have proven to be a very effective natural remedy for SAD, leading most practitioners to believe that normal neurotransmitter function depends in part on adequate vitamin D synthesis. > Vitamin D levels are inversely related to those of melatonin, another mood-regulating hormone. Melatonin helps modulate your circadian rhythms, with darkness triggering melatonin secretion by the pineal gland within your brain, bringing you down gently at night for sleep. Insomnia, mood swings and food cravings are influenced by melatonin. Sunlight shuts melatonin production off, while triggering release of vitamin D — that's why doctors recommend getting outdoors as a remedy for jet lag. > Most of us can sense the positive influence of sunlight in our own lives by the immediate lift we get from taking a walk outdoors on a beautiful sunny day. Now there may be many factors at work that brighten our mood in such cases, but sun exposure is almost certainly a critical piece. Soaking in the warmth of the sun is one of the most relaxing activities we share with all living creatures — just watch a cat dozing in a beam of sunlight. > Healthy sunbathing — is it possible? > Our bodies are remarkably efficient. During the summer months, even as little as 15 minutes in the sun (without sunblock!) in the early morning and late afternoon is enough for most light-skinned individuals to create an ample supply of vitamin D. Skin with more pigment (melanin) may require up to 40 minutes. > But you could say we are trading our longer lifespan for an increased risk of skin cancers, so don't throw away your sunblock! It's important to protect your skin, particularly on your face and scalp, during the sun's peak hours (11 AM – 2 PM) by using a lotion with SPF–15 or more, preferably PABA–free. Melanoma is a serious condition, and I'm not in favor of increasing your risk with unhealthy sun exposure. > This means you should not be out in the sun unprotected for more than 15 minutes, twice a day, early in the morning and late afternoon. If you begin to turn red before 15 minutes, cover up completely or go inside. It is never a healthy practice to burn your skin. It is also not safe to use tanning beds as a source of vitamin D. Please click here to learn more about tanning beds and vitamin D. > I do believe from what I see in my patients here in Maine that the problem is on the rise. But it just makes good " body sense " to allow your skin to do what it already knows how — produce vitamin D with sunlight. What's more, unlike with supplements, it's impossible to get a vitamin D overdose from sun exposure. > Symptoms of vitamin D overdose or toxicity Vitamin D is fat soluble, meaning it is stored in your fat cells. It is not excreted daily like many other essential nutrients and can build up to unhealthy levels. And once you overdo it on vitamin D, it's not an easy situation to rectify. That's why it's absolutely vital that you approach vitamin D supplementation only under the care of a medical professional. > Vitamin D overdose leads to calcium toxicity, which can cause nausea, vomiting, decreased appetite, constipation, weakness, and weight loss. It raises levels of blood calcium and can create a confused mental state and heart arrhythmia. Too much calcium and phosphorous can cluster in your body's soft tissues and disrupt kidney function (remember, calcium and vitamin D work together). It can also cause kidney stones and hardening of the arteries, or atherosclerosis. > Understanding your own individual needs and levels of tolerance for vitamin D are important parts of healthy self-care. Don't just assume that because you live at a far northern (or southern) latitude, or work indoors and don't get much sun exposure that you're vitamin D deficient and need supplements. To fully answer that question you must see a medical professional and get a blood test. > What you can do to prevent vitamin D deficiency > Vitamin D deficiency may be a pervasive problem — one that we treat with specific therapies at our medical practice — but the best way to protect yourself from any deficiency is to build your health from the bottom up and let your body balance itself. We acknowledge the controversy over whether our primary source of vitamin D should be the sun, diet, or supplements. Which combination is best for you depends on many variables, including your age, nutritional status, and geographic location. In a world where so many of us are at risk of vitamin D deficiency, we recognize each of these sources as valuable. With this in mind we recommend the following steps to prevent vitamin D deficiency: > > Eat a diet rich in whole foods and complex carbohydrates. Nutrient-dense, fatty fish like mackerel and sardines are good sources of vitamin D. Eggs, fortified organic milk and other dairy products, and some organ meats (like liver) are also good natural sources of D. Because vitamin D is still somewhat of a mystery, we're not sure which co-factors are important, but we know they are most fully present in wholesome food. > > > Take a top-quality multivitamin every day to fill in any nutritional gaps, preferably one that includes fish oil. Your supplement should have a minimum dose of 200 IU of vitamin D. To be on the safe side, it should not exceed 1000 IU, to avoid vitamin D overdose. (We've designed our own multivitamin that we can offer our patients with confidence. Click here to read about our Essential Nutrients.) > > > Allow yourself limited, unprotected sun exposure in the early morning and late afternoon (no more than 15 minutes for light-skinned individuals, 40 minutes for darker skin) — particularly between May and September if you live in northern regions. > > > Check with your healthcare professional about vitamin D testing. If you think you may be suffering from vitamin D deficiency, get a blood test and ask for the results. I like to see an optimal value of 50–100 ng/mL. A conventional doctor might think anywhere from 20–50 ng/mL is normal, but that recommendation will soon change as the newest research becomes incorporated into the standard of conventional care. Discuss adding a vitamin D supplement to your diet during the winter months or if you get inadequate sun exposure. This is especially important for women over 50. Then be sure to get follow-up testing to monitor your response. > And keep in mind that in the end, optimal health is never about just one thing. Vitamin D is just one component of an ever-changing picture — your health is a work in progress that needs your consistent attention and support. > It may turn out that vitamin D is the key everyone's been looking for, or more likely an important part of a much larger mechanism. But what matters most is how you feel and what works for you. I encourage you to investigate your personal vitamin D level with your medical practitioner as part of a comprehensive approach to your whole health. > Our Personal Program is a great place to start The Personal Program promotes natural hormonal balance with nutritional supplements, our exclusive endocrine support formula, dietary and lifestyle guidance, and optional phone consultations with our Nurse-Educators.

Guest guest Posted January 26, 2008 Report Share Posted January 26, 2008 Actually I have never " recommended " a dose. I have told people the amount my family and I take to reach the " optimal " blood levels of vitamin D as recommended by cutting edge vitamin D researchers. Their papers and research can be found here... http://www.vitamindcouncil.com/research.shtml The amounts that someone pasted below, on the order of 200 IU, etc, were decided on like 60 years ago when the only thing known about vitamin D was the minimum amount necessary to prevent rickets. That's it. Since then it has been found that vitamin D is one of the key players in the human body, it is a steroid hormone precursor. As one doctor puts it, vitamin D has " profound implications for the natural human condition. " Recent science can measure that our bodies can make on the order of 20,000 IU vitamin D in just a few minutes of exposure of summer sun. There is no toxicity at all. People that work outside, like lifeguards, concrete finishers, etc, typically have blood levels above 50ng, all the way up to 90ng/ml. I have a big problem with the RDA recommending only 200iu, the result for 99% of the population is EXTREME deficiency and at huge risk for causing seventeen varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, and periodontal disease. Yes, vitamin D has a hand in all these diseases...the papers, the science is there. Problem is, vitamin D is cheap, non patentable, so there is no room for paid research. Otherwise vitamin D would be the biggest blockbuster drug of all time. What really doesn't make sense is that 200iu is recommended universally, when they already know that the ability to absorb vitamin D through the skin is profoundly affected by race, where you live, genetics, BMI, lifestyle, age, etc. The only real way to know how much to take is blood testing. Funny, people have their blood checked for cholesterol, PSA, and a variety of other markers. But blood testing of vitamin D is only now starting to gain hold.

Yes; but the post states that if we took the same 20,000 IU of vitamin D as a pill it might be toxic. There seems to be some kind of natural control to prevent us from getting a toxic quantity from the sun. At least that's what I got...

Guest guest Posted January 27, 2008 Report Share Posted January 27, 2008 , You do raise a critical issue...while it is impossible to become vitamin D toxic from the sun (the excess " pre-D " is disposed of in the skin); it is possible to become toxic on excessive supplementation, so that's why I stress blood testing. IMO though, going through the trouble to raise 25-hydrox-D to optimal levels (50-60ng/ml) is worth it though. The benefits are just too incredible. Just ran across an fun and informative video given by Holick, PhD, MD, Professor of medicine, physiology and biophysics and director of the General Clinical Research Center at Boston University Medical Center. He was the former HEAD of the dermatology dept, but was fired from his views that SOME sunlight exposure was healthful. In the current medical thinking in dermatology circles, any sun exposure is horrifying. I would be curious to know what you think of the video...Neil http://www.uvadvantage.org/portals/0/pres/ > > > > > > On the vitamin D post did you folks see this part [below]?

Guest guest Posted January 29, 2008 Report Share Posted January 29, 2008 Sounds controversial... http://www.ncbi.nlm.nih.gov/pubmed/18177949 (they speak about " immune regulation/- modulation " - as by LDN, some say " boosting " , some say " supressing " ... Maybe better not to take Vit. D in Pillform (awaiting study-results) and sitting before a UV-Lamp (fullspectrum Daylight)? thaddus Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 29, 2008 Report Share Posted January 29, 2008 I wonder whether it was supplemental D2 or D3 that was looked at to come to the conclusion that "vitamin D is immunosuppressive and that low blood levels of vitamin D may be actually a result of the disease process. Supplementation may make the disease worse."

Guest guest Posted January 29, 2008 Report Share Posted January 29, 2008 This report really doesn't give enough information about how this study was conducted to be informative. And some of the examples about supplementing are inept. For example: " Supplemental vitamin D has been used for decades, and yet the epidemics of chronic disease, such as heart disease and obesity, are just getting worse. " All the OTHER gazillion vitamin D research has described this same circumstance but reaches a different conclusion. In these same decades we've been warned to stay out of the sun and/or to wear sunblock. And to blame vitamin D supplementing for obesity without mentioning 'high fruitose corn syrup' and lack of exercise... ??? Jann Quote Link to comment Share on other sites More sharing options...
