Vitamin and Supplements
New research from Albert Einstein College of Medicine of Yeshiva University shows that seven out of ten US children do not have enough vitamin D to sustain good health, putting millions of children at risk for heart disease, and high blood pressure. Researchers looked at 6000 children to find the widespread prevalence of vitamin D deficiency, defined at less than 15mg/ml. Vitamin D insufficiency is defined as 15 to 29/ml of blood.
Taking multivitamins or dietary supplements is a routine practice for many people. But, what may be beneficial and safe for one person, can be ineffective or even potentially dangerous for another.
Researchers and physicians at the Ohio State University Medical Center are utilizing the genetic-based information of individuals to assist in developing tailored medical and therapeutic treatments. The innovative research program is transforming the delivery of health care using a more personalized, cost-effective approach to wellness.
Marketed as supplements with synthetic steroids, these products are considered to be alternatives to anabolic steroids by American Cellular Laboratories, Inc. This is far from the truth. The FDA recently sent a letter to the company warning that their product was not a dietary supplement and that they were using unapproved drugs that had not been reviewed for safety through the FDA for safety. Apparently, the supplements have resulted in some adverse events that involve men between the ages of 22-55.
The American Academy of Dermatology (Academy) recently issued an updated position statement on vitamin D after an updated review of the increasing body of scientific literature on this vitamin and its importance for optimal health.
The Academy continues to recommend that the public obtain vitamin D from nutritional sources and dietary supplements, and not from unprotected exposure to ultraviolet (UV) radiation from the sun or indoor tanning devices, as UV radiation is a known risk factor for the development of skin cancer.
Fish oil (EPA & DHA) supplementation helped the heart when paired with a low-fat diet, but not when added to a high saturated-fat diet fed to rats with heart failure, according to a study in Hypertension: Journal of the American Heart Association.
A group of six researchers from different institutions, led by William C. Stanley, Ph.D., from the University of Maryland-Baltimore, hypothesized that when the heart is stressed, such as in heart failure, a high-fat diet may block the heart cells’ ability to absorb the heart-healthy omega-3 polyunsaturated fatty acids (PUFAs) found in fish oil.
Retinoic acid, a derivative of vitamin A, could lead researchers to a new set of drug targets for treating breast cancer, researchers from the University of Chicago report in the June 26, 2009, issue of the journal Cell.
The potential health benefits of vitamin D and marine omega-3 fatty acids are receiving increasing attention in both the media and medical field; however, definitive evidence on the health benefits and risks of these supplements is not yet available. Researchers at Brigham and Women's Hospital (BWH) will soon launch the largest randomized trial of vitamin D and omega-3s in the primary prevention of chronic disease.
Health Canada is advising Canadians to carefully read the labelling of iron supplement products as there is potential for confusion about dosage. Products currently on the Canadian market display the dose in different ways on the product label and consumers may misinterpret the amount of iron in the product and potentially take an incorrect dose. The potential for harm from consuming too much iron includes adverse effects such as constipation, nausea, vomiting and diarrhea.
At very high doses, iron may cause serious harm. Children may be particularly at risk for overdose.
Health Canada is advising expectant mothers and breastfeeding women not to take the vitamin-mineral supplements Maxum Matragen or Maxum Multi-Vite by Seroyal International Inc. Maxum Multi-Vite has been approved as a vitamin-mineral supplement for only the general public but lacks the required cautionary statement on the label regarding pregnant and/or breast feeding women.
The product Maxum Matragen is being promoted by the company as a prenatal supplement; however, neither product has been authorized for sale by Health Canada for use by women who are pregnant or breastfeeding.
Results of a new study show that cancer patients can benefit from ginger supplements. University of Rochester Medical Center found that ginger could reduce nausea by forty percent when taken before chemotherapy.
The study is the first to focus on using ginger combined with anti-nausea drugs to help relieve nausea associated with chemotherapy. Patients studied had a significant reduction in nausea from taking fresh ginger three days before chemotherapy and three days after treatment.
The U.S. District Court for the Eastern District of Michigan, Southern Division, today entered a consent decree that condemns and forfeits to the United States for destruction about $1.3 million worth of dietary supplements.
Researchers at the University of Warwick say older people can reduce risk of heart disease and diabetes by spending more time outside in the sunshine. Lifestyle changes and increased age lead to vitamin D deficiency, in turn leading to metabolic syndrome, heart disease, and diabetes. The scientists suggest that older people spend less time outdoors in the sun, and wear protective clothing outdoors, putting them more at risk for heart disease and diabetes from vitamin D deficiency.
Nature & Health Co., located in Brea, California, announced that it is conducting a voluntary nationwide recall of the company's supplement product sold under the name Libimax. The Company has been informed by representatives of the Food and Drug Administration (FDA) that lab analysis by FDA of Libimax samples found the product contains tadalafil, an active ingredient of an FDA-approved drug for erectile dysfunction (ED), making Libimax an unapproved drug.
Vitamin D levels tend to be very low in very sick patients, found Australian researchers. The sicker patients are, the lower the Vitamin D levels.
Dr Paul Lee, Professor John Eisman and Associate Professor Jackie Center, researchers at Sydney's Garvan Institute of Medical Research, examined a cohort of 42 Intensive Care Unit (ICU) patients. Forty-five percent turned out to be Vitamin D deficient.
These findings will be published as a letter in the April 30, 2009 issue of the New England Journal of Medicine.
If you knew you could reduce your risk of fractures by up to 20%, would you do it? A new study published in this month’s Archives on Internal Medicine shows that taking daily supplement doses of Vitamin D can do reduce the risk of fractures in older adults by up to 20%.
Vitamin D levels in Americans have plummeted in the last two decades. Vitamin D deficiency, which is the subject of much current research, has been linked to several disease, including multiple sclerosis, particularly pediatric multiple sclerosis. Consequently, in October 2008, the American Academy of Pediatrics doubled the minimum requirement for vitamin D in children. Several studies conducted in the last two years show an association between vitamin D deficiency and heart disease, breast cancer, prostate cancer, osteoporosis, rickets and autoimmune diseases.
Low levels of vitamin D were associated with an increased risk of high blood pressure, high blood sugar and metabolic syndrome in teenagers, researchers reported at the American Heart Association’s 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.
In the study, researchers analyzed 3,577 adolescents, 12 to 19 years old (51 percent boys), who participated in the nationally representative National Health and Nutrition Examination Survey (NHANES) conducted from 2001–2004.
Children born to women who have low blood levels of vitamin B12 shortly before and after conception may have an increased risk of a neural tube defect, according to an analysis by researchers at the National Institutes of Health, Trinity College Dublin, and the Health Research Board of Ireland.
Women with the lowest B12 levels had 5 times the risk of having a child with a neural tube defect compared to women with the highest B12 levels.
Vitamin D may emerge as an important player in the fight against winter coughs, colds and flu. University of Colorado Denver (UC Denver) School of Medicine, Massachusetts General Hospital (MGH) and Children's Hospital Boston have gathered data from a large scale study showing that vitamin D deficiency, especially during winter months, may make us more susceptible to respiratory infections.
The risk of cough, colds and flu is even higher in those with lower vitamin D levels and asthma or emphysema.
Health Canada is informing expectant mothers and women who are planning pregnancy taking the product PregVit Folic 5 and/or PregVit distributed by Duchesnay Inc. to check the product's individual sealed packages. Reports related to incorrect packaging of some blister packs have been received by Health Canada; however no concerns have been raised regarding the tablets themselves.
You may be wondering at this point whether to toss those vitamins into your mouth or into the trash. That's not surprising since several recent reports have called the value of vitamins into question, leaving people to wonder if it's time to ditch their supplements all together.
"People are so confused," says Elisabetta Politi, the nutrition director at the Duke Diet and Fitness Center. "But vitamins are like insurance, and there's no evidence that taking them is harmful."
Arab-American women living in southeast Detroit whose conservative dress limits their exposure to sun should be taking a vitamin D supplement to boost their dangerously low serum levels, according to a study published by Henry Ford Hospital researchers.
Researchers found that all 87 women involved in a small study showed vitamin D levels averaging 8.5 ng/mL (nanograms per milliliter) for those who wore western dress to 4 ng/mL for those who wore the hijab, modest dress with a headscarf. A healthy vitamin D level is 30 ng/mL or higher.
Omega 3 fatty acids, found in fish, canola oil, and over the counter supplements, are now found to protect against liver problems associated with obesity. The findings are important to clinicians for providing education to obese patients about how to prevent medical complications of obesity, while guiding weight loss.
The National Institute of Standards and Technology (NIST) has developed a new certified reference material that can be an important quality assurance tool for measuring the amounts of vitamins, carotenoids, and trace elements in dietary supplements. The new Standard Reference Material (SRM) 3280 for multivitamin/multimineral tablets was created in collaboration with the Office of Dietary Supplements (ODS) at the National Institutes of Health (NIH).
Like the workings of Wall Street or the mechanics of rocket science, the role of Omega-6 fatty acids in the diet hasn't been fully understood.
But the American Heart Association just declared Omega-6s - found in vegetable oils, nuts and seeds - a beneficial part of a heart-healthy eating plan.
For nearly a decade researchers worldwide have been investigating a link between vitamin D deficiency and autoimmune diseases, particularly multiple sclerosis (MS). In patients with the autoimmune hyperthyroid disorder Graves' disease the link has been explored even further with evidence suggesting that genetic polymorphism of the vitamin D receptor sometimes seen in patients with Graves' disease prevents adequate absorption of the vitamin D hormone.
According to a new study, Vitamin D is essential for muscle strength in adolescent girls, yet vitamin D deficiencies may be undetected. Vitamin D deficiency was discovered a large portion of 99 adolescent girls who took part in a study that measured vitamin D levels and muscle strength. The researchers found there were no symptoms among the vitamin D deficient girls. Furthermore, the girls performed poorly on muscle strength and velocity tests that used jumping exercises.
