Conclusive evidence that vitamin C reduces blood pressure and improves serum lipid profiles is frustratingly elusive. The latest study, a randomised crossover trial in healthy older adults, finds that 500 mg a day has a small effect on systolic blood pressure and a similarly small effect on high density lipoprotein cholesterol, but only in women (Journal of Hypertension 2000;18:411-5).
