A daily multivitamin tablet may boost the memory and slow mental decline, the Daily Mail reported Sunday.
According to new studies, taking supplements has a beneficial effect on memory and may work by increasing the efficiency of brain cells.
One study showed that after just four weeks there were measurable changes in electrical activity in the brain when carrying out memory tests. Vitamin C keeps cells healthy, D regulates calcium and E maintains cell structure, while the B vitamins, including folic acid, have a wide range of functions. The actual dose of vitamin D you get from a supplement can vary widely from the amount listed on the label, a new study finds. The amount of vitamin D found in pill tested in the study ranged from 9 to 146 percent of the amount listed on the label, the researchers said. Inaccurate supplement labels pose the biggest worry for people who have low vitamin D levels, said study researcher Dr.
In the study, the researchers analyzed 12 bottles of vitamin D supplements (each made by a different manufacturer), bought at 5 different stores in Portland, Oregon, and tested five pills from each bottle. When the researchers calculated the average amount of D in the five pills, this dose was generally closer to the labeled amount.
Supplements are not inspected before they come to market to make sure they contain accurate amounts of nutrients.
Cohen suspects that over-the-counter medications, which are regulated by the FDA, would be much less variable in their doses. I recommend getting your vitamin D level tested at least once per year, when your levels are likely to be at its lowest. A robust and rapidly growing body of research clearly shows that vitamin D is absolutely essential for good health and disease prevention, in part due to the fact that it influences about 10 percent of all your genes.
The US Preventive Services Task Force recently proposed new guidelines for vitamin D screening,1 which can be crucial for a number of different health conditions. Unfortunately, the task force claims there's "inadequate evidence" to make a determination about the value of routine vitamin D screening for people with asymptomatic vitamin D deficiency.
In the end, the task force is leaving it up to individual doctors to make their own determinations as to whether a patient may benefit from vitamin D testing. From my perspective, it is simply reprehensible malpractice for a health care professional to fail to address your vitamin D level if you're pregnant or undergoing cancer treatment—it's just that important. As for cancer, there are well over 800 references in the medical literature showing vitamin D's effectiveness—both for the prevention and treatment of cancer.
Vitamin D has a number of potent anticancer effects, including the promotion of cancer cell death, known as apoptosis, and the inhibition of angiogenesis (the growth of blood vessels that feed a tumor).
Carole Baggerly, founder of the vitamin D research group GrassrootsHealth, believes that as much as 90 percent of ordinary breast cancer may in fact be related to vitamin D deficiency. An even more recent study,8, 9 published in the British Medical Journal on June 17, links vitamin D optimization to improved cancer prognosis among those with a family history of cancer—regardless of the type of cancer involved—and a reduced risk of death from any cause, courtesy of its multi-varied influence on your health.
The data showed a clear pattern: those with consistently lower vitamin D levels were more likely to die from various health problems, including cancer, compared to those with higher levels. In related news, an Indian study found that vitamin D and calcium supplementation in combination with exercise can aid prediabetic individuals by preventing the progression into full blown diabetes.
The treatment group received a once-weekly dose of 60,000 IUs of vitamin D3, along with 1,250 milligrams (mg) of calcium carbonate daily, for eight weeks.
Similar results11 were found in another recent randomized placebo-controlled trial12 investigating the effect of calcium and vitamin D supplementation on the metabolic status of pregnant women with gestational diabetes (GDM). Optimizing your vitamin D levels prior to, or at the very least during, pregnancy is important for other reasons besides protecting against gestational diabetes. The "core morbidities of pregnancy" were reduced by 30 percent in the women who took the high-dose vitamin D.
When it comes to vitamin D, you don't want to be in the "average" or "normal" range, you want to be in the "optimal" range.
As for HOW to optimize your vitamin D levels, I firmly believe that appropriate sun exposure is the best way.
If your circumstances don't allow you to access the sun or a safe tanning bed, then you really only have one option if you want to raise your vitamin D, and that is to take a vitamin D supplement. Vitamin K2 deficiency is actually what produces the consequences similar to vitamin D toxicity, which includes inappropriate calcification that can lead to hardening of your arteries.
While the US Preventive Services Task Force may be unclear on whether otherwise healthy people need to test their vitamin D levels, I believe the evidence is overwhelmingly clear: if your levels are consistently low, you will eventually suffer some kind of consequence. A Wired15 article published earlier this year discusses the revolutionary work of Elizabeth Holmes, a woman who invented a way to run 30 different lab tests on a single drop of blood.
I believe vitamin D testing should be at the top of virtually everyone's list—but especially pregnant women and cancer patients. For the past several years the data in support of increasing vitamin D intake for every living human has been mounting. Vitamin D is a fat-soluble prohormone and essential nutrient produced when ultraviolet radiation (UVB) contacts our skin. Low blood levels of vitamin D have now been associated with many different chronic diseases including cancer, coronary heart disease, multiple sclerosis, Alzheimer’s disease, tuberculosis, depression, hypertension, periodontal disease, schizophrenia, seasonal affective disorder and type 1 diabetes. In light of these findings, many nutrition researchers have argued for increasing recommended levels of vitamin D intake, but making population-wide recommendations have proved difficult for world health agencies because of large variability and uncertainty in vitamin D requirements. Because vitamin D is fat-soluble, it is retained in body tissues for several months after sun exposure. To further complicate matters, it is incredibly difficult to obtain vitamin D through dietary sources. Skin pigmentation, sun avoidance and body composition (high body fat) are all associated with vitamin D deficiency.


This week’s study by Anne Looker et al, suggests that increased body mass as well as awareness of skin cancer risk and use of sunscreen have contributed to a significant decline in vitamin D levels in north America in the past decade. The good news is that supplementation does appear to be effective at improving vitamin D status. Kevin Cashman et al offers estimations of dietary requirements of vitamin D for healthy adults. Remember this is most important if you are overweight, live north of San Francisco, get little sun exposure or have darker skin. Vitamin D supplements are easier to find than in the past, but they are usually packaged with calcium and are insufficient in dosage.
I will continue looking for a good vitamin D supplement and will post when I find one I am happy with.
A study published in the latest issue of the American Journal of Clinical Nutrition is the first to address how your choice of breakfast is correlated with the quality of food chosen during the rest of the day. Interestingly, breakfasts of lower energy density, such as cereal with milk and fruit, were an indication of a more diverse diet throughout the rest of the day.
People who chose breakfasts of higher energy density ate fewer different kinds of foods, but more pastries and junk foods.
The researchers also found that seventeen percent of people who ate breakfast reported items that could not be “grouped into the major food groups,” things such as pastries, confections and meal replacement drinks and bars.
In English, what this all means is that although eating breakfast alone does a body good, it is much better if your breakfast is cereal and fruit rather than eggs and meat.
There is no clear cause and effect in an analysis of this kind, however there seems to be a correlation between eating less healthy foods at breakfast and making poor food choices throughout the day. Even if your breakfast choice does not have a direct impact on the rest of your food selections, choosing cereals and fruit will certainly bring you a step closer to better health.
Erin LeBlanc, an investigator with the Kaiser Permanente Center for Health Research in Portland, OR. Pharmacopeial Convention — an independent organization that sets standards for dietary supplements, and certifies supplements for companies that allow their products to be tested.
Pieter Cohen, an assistant professor of medicine at Harvard Medical School and a general internist at Cambridge Health Alliance in Boston who was not involved in the study, has patients take D supplements to boost low vitamin D levels.
But current laws state that the dosages in supplements should match the amount listed on the label. She has a masters degree in journalism from New York University's Science, Health and Environmental Reporting Program.
However, the sunscreen that is used to protect us from skin cancer can also prevent us from getting enough vitamin D, especially during the winter. My recommendation is to get your vitamin D level tested at least once per year, when your levels are likely to be at its lowest. For pregnant women, optimizing your vitamin D is more important for your child's health and development than folate, which is routinely recommended for pregnant women. All in all, the studies followed more than 26,000 Europeans and Americans, aged 50 to 79, over the course of a 16-year period.
Since exercise is one of the most effective ways to improve your insulin and leptin sensitivity, this certainly makes sense. It is unclear, however, if bringing low vitamin D blood levels to normal through supplementation will affect progression to diabetes. Hollis and Wagner reveals even more reasons for addressing any vitamin D insufficiency during pregnancy. Hollis: "I'm telling every pregnant mother I see to take 4,000 IUs and every nursing mother to take 6,400 IUs of vitamin D a day.
GrassrootsHealth has a helpful chart showing the average adult dose required to reach healthy vitamin D levels based upon your measured starting point. The biological role of vitamin K2 is to help move calcium into the proper areas in your body, such as your bones and teeth.
The reason for this is because when you take vitamin D, your body creates more vitamin K2-dependent proteins that move calcium around in your body. And when you consider how inexpensive vitamin D testing is becoming, there's little financial disincentive to get tested at least once a year, in the middle of the winter when your level would be at its lowest.
Ideally, I recommend getting your level tested several times a year, at regular intervals, to ensure you're continuously staying within the ideal range. It's important to remember that optimal vitamin D levels appear to offer powerful PREVENTION of a whole host of chronic diseases, so please, do not wait for a problem to appear before addressing your vitamin D status.
This week the American Journal of Clinical Nutrition features a collection of new research articles addressing the trends in vitamin D status and optimal dose recommendations. It is probably best known for its role in bone metabolism (it has been shown to be more important than calcium for maintaining bone health), however recent studies indicate that vitamin D is essential for other physiological process as well.
For this reason, people living at far north latitudes are particularly vulnerable to vitamin D deficiency because they frequently do not store up sufficient vitamin D during the summer to sustain their needs during the winter. Fatty fish and eggs are the only natural sources of vitamin D, though they are probably insufficient to achieve optimal status. Though there is still some disagreement on what the optimum blood levels of vitamin D are, it is generally agreed that they are much higher than currently recommended by any world health organization. They performed a randomized, placebo-controlled study testing the effects of different vitamin D doses and how they effect blood vitamin D levels. Very rarely do I recommend vitamin supplements (they are not usually effective and are sometimes dangerous), but in this case the evidence is unequivocal. Men should be wary of excess calcium supplementation since it is associated with an increased risk of prostate cancer. The scientists combined dietary data from three continuous National Health and Nutrition Examination Surveys (1999-2004) to determine energy density, nutritional quality and variety of foods eaten.


Although breakfast eaters ate more total daily calories during the study, the foods they chose tended to be of lower energy density.
In other words, participants who ate cereal for breakfast were more likely to report eating a lot of fruits, vegetables, grains, legumes and other healthful foods overall.
Countless studies have shown that dietary diversity is one of the best predictors of good health. With this the authors of the study point out that a significant percentage of Americans do not eat “real food” for breakfast (somewhere Michael Pollan is smiling and nodding).
While it is possible that some people simply make unhealthy selections all the time, there is also a possibility that your breakfast choices affect metabolic and hormonal systems that alter your cravings for different foods over the course of the day. Pouring a bowl of whole grain cereal and adding some fruit is pretty simple, and I guarantee you it is easier than making eggs and sausage.
The amount of vitamin D in USP-certified pills was generally very close to the amount stated on the label. She also holds a Bachelor of Science in molecular biology and a Master of Science in biology from the University of California, San Diego. This is particularly important if you're pregnant or planning a pregnancy, or if you have cancer. They also received 50,000 IUs of vitamin D3 at the outset of the study, and another 50,000 IUs three weeks later. I think it is medical malpractice for obstetricians not to know what the vitamin D level of their patients is. These magnetic ballasts are well known sources of EMF fields that can contribute to cancer. Many experts agree that 35 IUs of vitamin D per pound of body weight could be used as an estimate for your ideal dose. It also helps remove calcium from areas where it shouldn't be, such as in your arteries and soft tissues.
Without vitamin K2, those proteins remain inactivated, so the benefits of those proteins remain unrealized. Individual articles are based upon the opinions of the respective author, who retains copyright as marked. Anyone living in San Francisco or further north cannot get enough sun exposure to achieve sufficient vitamin D status, particularly during the winter months. One of the principle motivations of the present studies is to inform new vitamin D recommendations. However, this suggestion is only sufficient to avoid deficiencies associated with bone loss and not other chronic diseases. Lower energy density foods have fewer calories per gram and are usually associated with more nutritious fare such as fruits, vegetables and grains. This was confirmed in this study, as higher energy density breakfasts predicted fewer beneficial micronutrients consumed overall. Not surprisingly, this group comprised the highest average energy density of any type of breakfast. In both men and women, breakfast energy density showed a linear positive association with BMI. Indeed, there are studies showing that people who eat whole grains in the morning have altered insulin responses for nine to twelve hours after eating. According to the USP, pills should contain between 90 to 120 percent of the dose stated on the label.
So remember, if you take supplemental vitamin D, you're creating an increased demand for K2. Her company, Theranos, rolled out its blood testing service in a Walgreens pharmacy in Palo Alto, California in the fall of last year. The information on this website is not intended to replace a one-on-one relationship with a qualified health care professional and is not intended as medical advice. Now new data suggest that the nutritional quality of your breakfast is also important for your health.
This means that even for people who do eat breakfast, if you eat foods with higher energy density you will probably weigh more. Last month, a study by Cohen and colleagues found that some dietary supplements contain high amounts of caffeine, even though caffeine is not listed on the label.
After six weeks, the treatment group had "significant reductions" in fasting plasma glucose, insulin, and LDL cholesterol compared to the placebo group.
I strongly recommend you avoid these types of beds and restrict your use of tanning beds to those that use electronic ballasts.
It is intended as a sharing of knowledge and information from the research and experience of Dr. The treatment group also showed improved insulin sensitivity, and had higher HDL cholesterol. Mercola encourages you to make your own health care decisions based upon your research and in partnership with a qualified health care professional.
