High blood viscosity, a robust predictor of cardiovascular disease risk, is also predictive of cognitive dysfunction in older people, and may be an early indicator of the risk of Alzheimer's disease.
Magnesium supplementation, particularly at doses over 370 mg per day, can significantly reduce both systolic and diastolic blood pressure in hypertensive and pre-hypertensive people, according to a new metanalysis of 22 trials.
The recent Preventive Services Task Force draft recommendation against routine Prostate Specific Antigen (PSA) screening has a lot of guys pissing vinegar, with some calling the new report "a death sentence." More moderate voices call for recognition of the limits of PSA testing while cautioning against sweeping policy moves. Integrative Urologist Dr. Geo Espinosa sheds some light.
A Cochrane Collaboration systematic review of 32 clinical trials involving nearly 75,000 elderly women, concludes that daily supplementation with vitamin D3 (cholecalciferol), significantly decrease all-cause mortality.
A protein originally isolated from the Aequorea victoria species of jellyfish, can improve cognitive function in older adults experiencing mild but troublesome impairment.
Cellular longevity is governed by telomeres, the DNA caps on the ends of chromosomes. Telomere length is regulated by an enzyme called telomerase. When telomerase activity is high, so is telomere length, and this delays cellular senescence. Substances including Omega 3s, vitamin D and folate have been shown to slow telomere shortening, but until recently researchers had not found anything that could actually activate telomerase and lengthen short telomeres. That changed with the discovery of a unique compound within the root of the Astragalus plant.
Phylloquinone, a naturally-occurring form of vitamin K, is found in several different types of foods.
