Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C, also known ascorbic acid, does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients according to the results published in the American College of Rheumatology (ACR) journal, Arthritis & Rheumatism. http://medicalxpress.com/news/2013-05-vitamin-uric-acid-gout-patients.html Health Thu, 16 May 2013 00:00:02 EST news287856837 Pregnant women are advised not to smoke during pregnancy because it can harm the baby's lungs and lead to wheezing and asthma, among other problems.
