Vitamin D may help to reduce the risk of developing type-2 diabetes.

Vitamin D is rapidly becoming one of the most studied vitamins of our time. These studies have indicated that vitamin D is closely linked with several aspects of human health and survival. A new meta-analysis (collective review and analysis of previous studies) published in the European Journal of Clinical Nutrition (July 2011), reported finding a clear correlation between vitamin D intake of greater than 500 IU per day and a 13% reduced risk for developing type-2 diabetes. It was also noted that those individuals with the highest blood levels of vitamin D (>25 ng/dl) had a 43% lower risk of developing type-2 diabetes than
those individuals with the lowest blood levels (<14 ng/ml). This research review shows that vitamin D may play a role in the development and progression of type 2 diabetes; however, more high quality studies will be needed to find how and to what extent it may be used in the course of this health-related condition.

Vitamin E tocotrienols provide cholesterol benefits.

Tocotrienols are members of the vitamin E family that have been proven to influence several aspects of health such as neurological conditions and free radical reduction. Over the years, tocotrienols have often been overshadowed by a more commonly known form of vitamin E - tocopherol. Though both forms share some health related aspects, research is finding that tocotrienols might have a greater impact on human health than previously believed. A recent study published in Nutrition & Metabolism (June 2011) reported that 6 months supplementation with tocotrienols was associated with an improvement in plasma cholesterol levels, decrease in advanced glycosylation end products (AGEs), and increased vitamin E levels and antioxidant enzyme activity. This study included 62 subjects from two age groups, 35-49 years and 50+ years, who were randomly assigned to receive either the tocotrienols or placebo for the 6 month period. Both HDL cholesterol levels and total plasma HDL to cholesterol levels improved. The reduction in AGEs, which are normally occurring by-products of metabolism and aging that have been associated with the progression of age-related diseases, was correlated to a reduction in oxidative stress and protein damage. Though more research is needed to discover all of the benefits tocotrienols have to offer, this study supports the necessity for that research.
