More Evidence to Show Vitamin D Has Anti-cancer Benefits
Scientists have found breast cancer patients with low levels of vitamin D were much more likely to die of the disease or have it spread than patients getting enough of the nutrient.Those who were deficient in the sunshine vitamin were twice more likely to suffer recurrence.
Those who had sufficient blood levels of the vitamin at the time they were first diagnosed fared much better, Canadian researchers said.
Vitamin B12
Vitamin B12 (cobalamin) functions as a coenzyme for a critical methyl transfer reaction that converts homocysteine to methionine and for a separate reaction that converts L-methylmalonyl-coenzyme A (CoA) to succinyl-CoA. The Recommended Dietary Allowance (RDA) for vitamin B12 is based on the amount needed for the maintenance of hematological status and normal serum vitamin B12 values. An assumed absorption of 50 percent is included in the recommended intake. The RDA for adults is 2.4 µg/ day of vitamin B12.
Surviving Antioxidant Supplements
An association between healthy diet and good health has been noted since Hippocrates (460-377 BC)-and in fact long before (1). Our diet provides numerous vitamins and trace elements that are essential to good health.
Vitamin D May Protect Against Peripheral Artery Disease
People with low vitamin D levels may face an increased risk for peripheral artery disease (PAD), according to researchers at the Albert Einstein College of Medicine of Yeshiva University. The scientists reported their findings at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology Annual Conference 2008.
The New Recommendations for Dietary Antioxidants
Summary: The Food and Nutrition Board has increased the RDA for vitamin C to 90 mg/day for men and 75 mg/day for women. The RDA for vitamin E was increased to 15 mg/day for men and women. The RDA for selenium was decreased for men to 55 micrograms/day and unchanged for women at 55 micrograms/day. No RDA was established for beta-carotene.
The Bioavailability of Different Forms of Vitamin C (Ascorbic Acid)
In the rapidly expanding market of dietary supplements, it is possible to find vitamin C in many different forms with any number of claims regarding its efficacy or bioavailability. Bioavailability refers to the degree to which a nutrient (or drug) becomes available to the target tissue after it has been administered. We reviewed the literature for the results of scientific research on the bioavailability of different forms of vitamin C.

Are All Vitamins Created Equal ?
I have posted this video to make clear that not every label will tell you what's in the bottle. The supplement market is a multi-milion dollar (or euro) market and there are alot of companies on the market who produce their products in a non-healthy manner.
Lack Vitamin E Levels Linked to Physical Decline in Older People
A lack of Vitamin E -- often a sign of poor nutrition -- is linked to physical decline in older people, according to a study published Wednesday in the Journal of the American Medical Association.Researchers studied nutrition and physical function in 698 people aged 65 and older in Tuscany, Italy, conducting baseline examinations followed by three-year follow-up assessments, from 1998 to 2003.In particular the scientists, led by Benedetta Bartali of the Yale University School of Medicine, measured levels of micr
Resveratrol from Grape Skin Could Help Prevent Diabetes Related Complications
When it comes to keeping complications of diabetes at bay, it seems that an apple a day may have to take a back seat to another fruit - grapes.Researchers at the Peninsula Medical School in the South West of England have found that the grape skin compound Resveratrol could stop complications of diabetes like heart disease, retinopathy and nephropathy (kidney disease). It does so by protecting against the cellular damage to blood vessels caused by high production of glucose.
Extract made from broccoli sprouts may inhibit the development of bladder cancer.
An extract made from broccoli sprouts may inhibit the development of bladder cancer.
Bladder cancer is the uncontrolled growth of cells, usually originating in the bladder lining. The bladder is an organ located in the pelvic cavity that stores and discharges urine. Urine is produced by the kidneys, carried to the bladder by hollow tubes called ureters and discharged from the bladder through a tube called the urethra.
Natural antioxidants in Alzheimer's disease. Pubmed Extract
Catholic University School of Medicine, Institute of Pharmacology, Largo F Vito, 00168 Roma, Italy.Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterised by severe cognitive impairment that ultimately leads to death. Current drugs used in AD are acetylcholinesterase inhibitors and antagonists to the NMDA receptors. These drugs may only slightly improve cognitive functions but have only very limited impact on the clinical course of the disease. In the past several years, based on in vitro and in vivo studies in laboratory animals, natural antioxidants, such as resveratrol, curcumin and acetyl-L-carnitine have been proposed as alternative therapeutic agents for AD. An increasing number of studies demonstrated the efficacy of primary antioxidants, such as polyphenols, or secondary antioxidants, such as acetylcarnitine, to reduce or to block neuronal death occurring in the pathophysiology of this disorder. These studies revealed that other mechanisms than the antioxidant activities could be involved in the neuroprotective effect of these compounds.
Oligomeric Proanthocyanidins Monograph (OPC)
Introduction Oligomeric proanthocyanidins (OPCs) are some of the most abundant polyphenolic substances in the plant kingdom. Proanthocyanidins are an integral part of the human diet, found in high concentrations in fruits such as apple, pear, and grapes, and in chocolate, wine, and tea. OPCs in nutritional supplements are generally extracted from grape seeds or pine bark. Due to potent antioxidant activity, OPCs have been the subject of recent research, demonstrating anticarcinogenic, anti-inflammatory, antimicrobial, and vasodilatory properties, making them a potentially valuable therapeutic tool for the treatment of a variety of conditions. Synonyms for oligomeric proanthocyanidins include procyanidins, procyanidolic oligomers (PCOs), leucoanthocyanins, condensed tannins, and pycnogenols, although the latter term is no longer used. Pycnogenol® is the trade name for an OPC extract from the bark of the French maritime pine tree. Jacques Masquelier of the University of Bordeaux, France, first studied OPCs in depth after reading of explorer Jacques Cartier’s 1534 expedition up the St.
Chronic Dietary Intake of Plant-Derived Anthocyanins Protects the Rat Heart against Ischemia-Reperfusion Injury1
Consumption of flavonoid-rich foods and beverages is thought to reduce the risk of cardiovascular diseases. Whereas the biological activities of flavonoids have been characterized in vitro, there are no clear experimental data demonstrating that chronic dietary intake and intestinal absorption of flavonoids actually protects the heart against ischemia-reperfusion injury. We tested whether long-term consumption of specific flavonoids (anthocyanins) included in normal food could render the heart of rats more resistant to myocardial infarction.
Sirtuin modulating compounds : Sirtris Pharmaceuticals, Inc Patent
The Silent Information Regulator (SIR) family of genes represents a highly conserved group of genes present in the genomes of organisms ranging from archaebacteria to a variety of eukaryotes (Frye, 2000). The encoded SIR proteins are involved in diverse processes from regulation of gene silencing to DNA repair. The proteins encoded by members of the SIR gene family show high sequence conservation in a 250 amino acid core domain. A well-characterized gene in this family is S.
