    Alpha-tocopherol does not impact gamma-tocopherol or tocotrienol concentrations

    Recent research conducted by Japanese investigators studied the impact of orally administered α-tocopherol on γ-tocopherol and tocotrienol depletion. Rats fed either a γ-tocopherol rich diet or a tocotrienol rich diet for 6 weeks were followed by a γ-tocopherol or tocotrienol free diet with or without α-tocopherol. The results showed that dietary α-tocopherol did not influence…

  • Cognitive Function, Dementia and Vitamin D Status.

    Cognitive Function, Dementia and Vitamin D Status.

    Research funded by the Ontario Research Coalition of Research Institutes/ Centres on Health & Aging examined the association between cognitive function and dementia with vitamin D concentration in adults. Studies containing data allowing mean Mini-Mental State Examination (MMSE) scores were compared between participants with Vitamin D levels <50 nmol/L to those with values ≥50 nmol/L.…

  • Vitamin D for Prostate Cancer?

    Vitamin D for Prostate Cancer?

    Accumulating evidence suggests that chronic prostatic inflammation may lead to prostate cancer development. Growth differentiation factor-15 (GDF-15) is highly expressed in the prostate and has been associated with inflammation and tu¬morigenesis. Researchers, led by Dr. Lambert, examined the relationship between GDF-15 and prostatic inflammation by measuring GDF-15 expression via immunohistochemical staining (IHC) in human prostatectomy…
