Vitamin C injections could play a role in treating blood cancers
Conclusion This mouse study explored whether treatment with vitamin C could restore function of TET2 and therefore block the progression of blood cancers like leukaemia. It found that using high doses of vitamin C intravenously did in fact suppress the growth of leukaemia cancer stem cells in the mice implanted with cell lines from human patients with leukaemia. It also reported that using vitamin C alongside existing treatment with PARP inhibitors helped reduce the progressions of the disease. The researchers suggest that in the future, vitamin C could be used alongside chemotherapy and other conventional treatment forms....

CRI scientists discover vitamin C regulates stem cell function, curbs leukemia development

Schools are back in session, which means the common cold is not too far behind.  To avoid a cold or cut one short, you may be tempted to stock up on supplemental drink mix-ins like Emergen-C and Airborne for supposed cold-fighting ingredients like vitamin C or zinc. But do these unregulated powders and tablets actually work? Unless you’re a marathon runner, skier or soldier in extremely cold temperatures, extra vitamin C probably isn't going to keep you from getting sick. And children are most likely to benefit from zinc, but their parents? Not so much.   The basics Vitamin C, or ascorbic acid, is an e...

Nature’s Most Powerful Age Fighter?
When I lecture at anti-aging conferences around the world, I get a good sense of what the leading anti-aging physicians are thinking about. And I’m surprised by how many are still holding out hope for an anti-aging “drug.” But I’m not holding my breath. And even if the FDA approved a drug for aging, it would likely include a laundry list of side effects, and only affect a small range of age-related decline. I’ve always had more faith in nature. Many of the most powerful age fighters are naturally occurring, and they do a better job of supporting and lengthening your telomeres than any drug. Te...

A novel highly sensitive ion-pairing reversed-phase high performance liquid-chromatography/electrochemical detection method for simultaneous determination of l -ascorbic acid, aminothiols, and methionine in biological matrices is presented. Reduced forms of the analytes are extracted from sample matrices with 10 % m-phosphoric acid solution(aqueous). To determine the total vitamin C, the total aminothiols, and the total methionine, samples are treated with tris(2-carboxyethyl)phosphine solution in 0.05 % trifluoroacetic acid solution(aqueous) subsequent to deproteination to reduce the oxidized forms of these compou...

Vitamin C not proven to 'boost' chemo
Conclusion Among 25 newly diagnosed ovarian cancer patients, those given vitamin C alongside standard chemotherapy were found to have significantly fewer mild to moderate treatment-related side effects than those on standard treatment. However, the researchers found no significant differences in terms of cancer survival, which was assessed up to five years after treatment. One explanation for this is that the study was too small to detect any effect, but this could also be because no survival benefit actually exists. It's also worth noting that the women knew whether they were given vitamin C, so the placebo effect&nb...
