In a trial of 719 people with new colds, illness ran 6.34 days on blinded echinacea versus 6.87 on blinded placebo, and severity scores also favored echinacea. Media reports framed the result as no significant benefit; changes in interleukin-8 and neutrophil counts were not significant.

Echinacea, vitamin C help common cold?
In a trial of 719 people with early cold symptoms, echinacea shortened illness by seven to 10 hours, a difference the researchers did not treat as significant, and did not ease severity. A 2007 Lancet Infectious Diseases review had reported larger benefits.

Antioxidants may help prevent breast cancer
An Indian study in the Asian Pacific Journal of Cancer Prevention measured plasma antioxidants in 225 women and found higher beta-carotene, vitamin E and vitamin C accompanying significantly lower breast cancer risk. Higher vitamin A levels went the other way, tracking with higher risk.

Calcium supplements versus myocardial infarction: What you need to know
University of Auckland researchers pooled more than a dozen trials and epidemiological studies covering 11,921 participants followed about four years, and found people taking calcium supplements were 30 percent more likely to suffer a heart attack. None of them took vitamin D alongside the calcium.

High-Dose Vitamin C Therapy Proven Effective (PR)
The Orthomolecular Medicine News Service argues that 75 years of physician reports and studies on high-dose vitamin C have been ignored, and that unsuccessful research used doses far too low to show results. It traces the approach to Jungeblut, McCormick, Klenner, Riordan and Cathcart.

Vitamin C cuts smoking-induced atherosclerosis risk
Guinea pigs exposed to cigarette smoke developed atherosclerosis, but those fed a vitamin C-supplemented diet rarely did, a Journal of Atherosclerosis and Thrombosis study found. The authors credit vitamin C with blocking smoke-induced apoptosis and platelet activation.

Swine flu, vaccine and vitamins
A Harvard School of Public Health poll found 44 percent of American adults believe the 2009 swine flu pandemic is over, and 40 percent of parents have had their children vaccinated. CDC reported flat activity and nine more child deaths that week.

Vitamin c help would healing
A 1982 report by Ringsdorf and Cheraskin described faster recovery in patients taking 500 to 3,000 mg of vitamin C daily after surgery, injuries and ulcers. Four grams a day also improved newly made collagen in a boy with Type VI Ehlers-Danlos syndrome.

Vitamin C, E, Omega 3-fatty acids prevent pancreatic cancer
In a San Francisco Bay Area case-control study, the highest intakes of vitamins C and E were tied to 31 and 33 percent lower pancreatic cancer risk and omega-3s to 53 percent lower, while high saturated fat intake was tied to 60 to 160 percent higher risk. Vitamins from food showed no link.

Vitamin C Protects Against Hypertension-Induced DNA Damage
In 32 male Wistar rats with surgically induced renovascular hypertension, seven days of vitamin C at 150 mg/kg protected blood, brain, liver and heart cells against hypertension-induced DNA damage and eased the hypertension itself, a Human & Experimental Toxicology study found.

Vitamin C enhances production of adult stem cells
Chinese researchers report in Cell Stem Cell that vitamin C improves the reprogramming of mouse and human adult cells into induced pluripotent stem cells. Other antioxidants did not do the same, so the team suspects the effect is not simply antioxidant activity.

Plagued with H1N1? Forget the Flu Vaccine, Try Vitamin C*
With the Obama daughters vaccinated against H1N1, the editor argues the vaccine is safe for healthy people but untested in pregnant women and those with medical conditions, and points to a 1999 study in which 1,000 mg doses of vitamin C helped prevent and treat cold and flu.

Vitamin C deficiency may impair brain development
Newborn guinea pigs with moderate vitamin C deficiency had 30 percent fewer hippocampal neurons and markedly worse spatial memory than those fed enough, a University of Copenhagen study found. The authors suggest deficiency in pregnant women may similarly affect infant brain development.
