Researchers followed 4,500 French men and women between the ages of 45 and 60 for eight years, with half the group taking a daily supplement and half taking placebo pills. After that period, all were given the option of taking vitamin supplements for six more years.
At the end of the six-year period, both groups were given a series of memory tests. The groups performed similarly on most of the tests, but the nutrient-taking group did better on long-term memory exercises than the placebo group.
The study was published online in The American Journal of Clinical Nutrition.
A couple of years ago my wife and I went and had a complete metabolic study and were prescribed a regiment of supplements. While initially believing that this was just nothing more than a way to drive supplement sales, the combination of the supplements actually improved our health and led to some incredible weight loss over six months. People who know what they are doing in this arena are invaluable. Beware of the hucksters however.
