There have been many efforts to produce an advanced resveratrol pill that stabilizes this wonder molecule, enhances its oral absorption, maximizes its immediate bioavailability (get as much unbound resveratrol past the liver’s detoxification system), enhances its biological activity, delivers it in modest doses to produce a hormetic effect (hormesis = provision of a biological stressor in a mild dose to activate the body’s internal antioxidant system) and deliver it safely without potential toxicity when administered intended or unintended mega-doses.

The problem is quite apparent – women over age 65 proportionally account for 63% of dementia sufferers worldwide and health authorities anticipate this difference will become more pronounced as more women live into their tenth decade of life. This problem is believed to emanate from a reduced ability of arteries in the brain to dilate (widen) under conditions of mental demand or emotional or physical stress.
The age-related decline in estrogen production from the ovaries is identified as a chief reason for these aging changes in mental function in women.

Ignoring prior science that shows the red wine molecule resveratrol blocks oxidative stress and convincingly prevents cell senescence, a researcher at Erasmus University Medical Center in the Netherlands says elimination of senescent cells from an aging body is now plausible.
As cells age they lose their ability to divide and replicate. This so-called cellular senescence is an obvious hindrance to the growth of cancerous cells but removal of senescent cells from animals resulted in animals hair regrowth, improved organ function and faster-paced running. [Science Daily Dec 29, 2016] So reversal of cell senescence (not just slowing senescence) appears to be a bona fide anti-aging strategy.

The first images of laboratory mice reprogrammed to reverse aging are presented above. [Cell Dec 15, 2016] Laboratory mice genetically altered to age prematurely show signs of age reversal upon epigenetic reprogramming. The mouse on the right (-Dox) exhibits a curved spine characteristic of a premature aging syndrome called progeria in humans. The reprogrammed mouse on the left (+Dox) exhibits a more youthful thicker coat and absence of the abnormal spine curvature. Internal organs were also more youthful in reprogrammed mice. Animals were genetically altered to produce a premature aging syndrome akin to progeria, which results in shortened lifespan (~13 years in humans) with premature baldness, cataracts and skin wrinkling in youth. While progeria is caused by a mutation in a single gene (LMNA, pronounced lamin-A) researchers were able to reverse aging changes in these animals by alteration of protein-making (i.e. epigenetics) in just four genes (known as Yamanaka factors). Mice and humans house a similar library of genes (~25,000) in the nucleus of their cells. The age-reversal effects were accomplished by returning cells back to their original embryonic state in order to remove certain epigenetic marks that occur in aging without altering the abnormal sequence of DNA (gene mutations) responsible for premature aging itself. This suggests biological fate can be changed.

Researchers report the administration of resveratrol to newborn rodents whose brains were experimentally deprived of oxygen after birth reduced tissue damage 7-days after the event and protected the newborn brain. [Oncotarget Nov 2, 2016]
Researchers say: “The immature brain is unable to repair itself from this injury; however, resveratrol may preserve the structure and morphology (physical makeup) of injured tissues and prevent dysfunction in the affected brain cells (neurons)” even 7-days after the event.

Modern medicine is getting into the soothsayer business. Various technologies now make it possible to foresee the health future of an individual and predict with some certainty which maladies may befall a person years before symptoms or signs become apparent.

Blood plasma exchange from old to young, modified versions of calorie restriction and a third new approach to super-longevity have emerged in the past year. Humans now have instruction how to achieve an indefinitely long lifespan.
Short of having surgeons intertwine your organs and blood vessels with another younger individual in an intervention called parabiosis that was previously shown to improve health and prolong life of laboratory animals, researchers recently infused blood plasma from young adult humans into to old mice which resulted in a similar dramatic rejuvenation of the body and brain. New cells were created in the hippocampus, the thinking lobe of the brain. Researchers describe young blood plasma as having a “massive rejuvenating effect.” [Daily Mail Nov 15, 2016]

The study was compelling. Bacteria samples were taken from twins, one lean the other overweight, and implanted into the gut of healthy mice. The results were astounding. Mice that received gut bacteria from the lean twin remained healthy and lean while the mice that received bacteria from the overweight twin piled on a massive amount of weight. [Science Sept 6, 2013]

Two-thousand years ago Roman soldiers wrapped their wounds in wine-soaked bandages and chewed garlic going into battle as an antibiotic. From that point forward we can’t say modern pharmacology has advanced much beyond that point.
The broad biological action of the molecules in grapes and garlic cloves activate key genes (mTOR, AMPK, NF Kappa B, Sirtuin1, Sirtuin3, Foxo1 and Nrf2) that perform beyond the limited capacity of any synthetically made molecule. [Resveratrol News Dec 15, 2015]
