Antioxidant Vitamin C attenuates experimental abdominal aortic aneurysm development in an elastase-induced rat model. Vitamin C helps to strengthen the aortic wall. Small aneurysms, bulging areas that indicate weak artery walls, can also be reversed with vitamin C. This suggests many thousands of cases of brain or aortic aneurysms can possibly be remedied with supplemental vitamin C. After a time Dr. Bush judged that over 90% of patients with arterial disease can be improved with 3000 milligrams of vitamin C per day, but some need over 10,000mgs/day … One of the common results of this vitamin C shortage is a deterioration of the aorta that can result in aneurysm. Vitamin C attenuated AAA development in an elastase-induced rat model via crucial protective effect, which was mediated by an increased level of antioxidant in cooperation with preserving elastin lamellae, inhibiting matrix-degrading proteinases and suppressing inflammatory responses. 3. Pooled analyses of the 4 case-control studies demonstrated significantly lower circulating vitamin B6 levels (SMD, -0.33; 95% CI, -0.55 to -0.11; P=0.003) but non-significantly lower vitamin B12 levels (SMD, -0.42; 95% CI, -1.09 to 0.25; P=0.22) in patients with AAA than subjects without AAA. Vitamin C attenuated the development of AAA, decreasing maximal aortic diameter by 25.8% (P < 0.05) and preserving elastin lamellae (P < 0.05).
