levels of 1,168 subjects between the ages of 65 to 79 who suffered hip fractures during up to 11 years of follow-up were compared to those of 1,434 control subjects from the same cohort.
They randomly assigned participants into four treatment groups: 2000 IU/d of alpha-tocopherol
(n = 152), 20 mg/d of memantine (n = 155), the combination (n = 154), or a placebo (n = 152).
Cook-Mills had done previous allergy research in mice showing alpha-tocopherol
decreased lung inflammation, protecting healthy lung function and gamma-tocopherol increased lung inflammation and airway hyperresponsiveness, a characteristic of asthma.
Miia Kivipelto, director of the research from University of Eastern Finland, vitamin E exists in eight different natural forms (fat-soluble compounds) and the entire vitamin E family plays a role in protecting against memory disorders, not only alpha-tocopherol
in human spermatozoa and seminal plasma: relationships with motility, antioxidant enzymes and leukocytes.
Unlike the regular vitamin E alpha-tocopherol
, tocotrienol exists scarcely in nature and is especially low in Western diet.
There were small but significant increases in the proportion of alpha-tocopherol
in beans from the same genetic line grown in warmer, full-season Eastern Shore locations compared to beans that matured under slightly cooler conditions.
5-fold increase in relative alpha-tocopherol
content, compared to the other years during which rainfall was adequate.
The scientists attempted to form and characterize cyclodextrin inclusion complexes with the natural antioxidants alpha-tocopherol
The authors do not recommend vitamin E supplements to increase levels, since the approximately 15mg to 30mg per day of dietary alpha-tocopherol
(a component of vitamin E) needed can easily be reached through diet, from sources such as almonds, tomato sauce and sunflower seeds, among others.
Beta-Carotene Cancer Prevention Study Group.
decreases superoxide anion release in human monocytes under hyperglycemic conditions via inhibition of protein kinase C-[alpha].
source used was Roche ROVIMIX E50, an alpha-tocopheryl acetate containing 500 mg [alpha]-tocopherol [g.
Another form of vitamin E, known as alpha-tocopherol
, found naturally in olive oil, almonds, and sunflower seeds, appeared to be harmless.
However, just a few weeks later, results from the Alpha-Tocopherol
, Beta Carotene (ATBC) Cancer Prevention Trial showed that men with high blood levels of alpha-tocopherol
(a form of vitamin E) had a lower risk of prostate cancer, reports Harvard Men's Health Watch.
