In a double blind, placebo-controlled study of overweight and obese people, participants received either 4,000 IU daily of vitamin D or a placebo for 13 weeks, in combination with resistance training. Researchers observed a significant decrease in the waist-to-hip ratio for the supplemented group, and stated that the “study demonstrated that vitamin D supplementation improved…

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…

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.

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…
