Fisetin neuroprotective against Huntington’s disease

Salk.edu – Fisetin, a natural phytochemical found in strawberries and other fruits and vegetables, slows the onset of motor problems and delays death in three models of Huntington’s disease, according to researchers at the Salk Institute for Biological Studies. The study, published in the online edition of Human Molecular Genetics, sets the stage for further investigations into fisetin’s neuroprotective properties […]

Vitamin C may be life-saving treatment for sepsis

Physicians caring for patients with sepsis may soon have a new safe and cost-effective, natural treatment for this life-threatening illness – Vitamin C.

How SAM-e, vitamin B6 boost hydrogen sulfide in body

UMich.edu – How the dietary supplement SAM-e boosts the activity of a natural protein that uses vitamin B6 to make more hydrogen sulfide in the body has been revealed by researchers at the University of Michigan. The researchers have solved the structure of this protein that is integral to processes responsible for maintaining a healthy heart and nervous system. The protein […]

DHA-enriched milk might help brain development of preemies

ULaval.ca – Giving breastfeeding mothers DHA supplements, a type of omega-3 fatty acid, increases the concentration in their milk of this nutrient essential to brain growth and brain development, concludes a study presented recently by Université Laval researcher Dr. Isabelle Marc at the Pediatric Academic Societies annual meeting in Vancouver, Canada.

Omega-3 fatty acids may fight gum disease

Long-chain omega-3 fatty acids, like DHA and EPA, may serve as a natural treatment to help fight gum disease, according to a new study. Periodontitis, a common inflammatory disease in which gum tissue separates from teeth, leads to accumulation of bacteria and potential bone and tooth loss. Although traditional treatments concentrate on the bacterial infection, more recent strategies target the inflammatory […]
