A study in a recent edition of the Archives of Neurology reports about 4740 patients from Cache County, Utah, who were 65 years or older and were followed over 5 years. At the start it was found that those who had taken vitamin C and E on a regular basis as separate supplements had a 78% lesser risk of developing Alzheimers (correct medical term: “Alzheimer’s disease”).
5 years later out of 3227 survivors who were at risk 104 more people had developed Alzheimers, but 64% of those who combined vitamin C and E as a supplement did not develop Alzheimers. Dr. Peter Zandi from the Department of Mental Health, Bloomberg School of Public Health, The Johns Hopkins University/ Baltimore, Md was the lead author of this study. He stated that this was only an observational study, but that the data was convincing enough to warrant a full-scale controlled trial to examine the value of anti-oxidant agents (such as vitamin C and E) as a preventative against Alzheimers. There were a number of built-in controls such as vitamin C alone, vitamin E alone and multiple vitamins (including vitamin C and E in smaller dosages) that were all ineffective in preventing Alzheimers. The daily dosages that were necessary for the protective effect were vitamin C 500mg to 1000 mg or more per day as well as 400 IU to 1000 IU of vitamin E per day. The U.S. recommended daily allowance was insufficient for the protective effect. These dosages typically are in the order of 22 IU of vit. E and 75 to 90 mg of vit. C. Vitamin B complex alone was also ineffective in protecting against Alzheimers.
Vitamins C And E – A Weapon Against Alzheimers
Comments: There are many unanswered questions about Alzheimers, but this paper gives valuable hints in terms of the protective effect of two vitamins (vitamin C and E taken as separate supplements daily). There are other factors such as genetic ones and perhaps a dysregulation of the cholesterol brain metabolism that lead to the production of a glue-like substance, called “beta-amyloid” ,that causes memory loss in Alzheimers patients. Testosterone has recently also been noticed to be important in the prevention of Alzheimers disease. In addition to these vitamin supplements a low glycemic, low fat diet would likely be very beneficial together with a regular exercise program and calorie restriction to prevent Alzheimers disease in many patients (prevention of the metabolic disease).
