Dietary Supplement Niagen Shows Hope For Reversing Cardiovascular Aging

Scientists stimulate got long known that restricting calories tin fend off physiological signs of aging, with studies inwards fruit flies, roundworms, rodents too fifty-fifty people showing that chronically slashing intake past times near a tertiary tin reap myriad wellness benefits and, inwards simply about cases, extend lifespan.

From a world wellness perspective, that advice would survive impractical for many too unsafe for some.
But a novel University of Colorado Boulder study published today indicates that when people eat a natural dietary supplement called nicotinomide riboside (NR) daily, it mimics caloric restriction, aka "CR," kick-starting the same cardinal chemic pathways responsible for its wellness benefits.
Supplementation also tends to amend blood pressure level too arterial health, peculiarly inwards those with mild hypertension, the study found.

"This was the outset e'er study to plough over this novel chemical compound to humans over a menstruum of time," said senior writer Doug Seals, a professor too researcher inwards the Department of Integrative Physiology. "We flora that it is good tolerated too appears to activate simply about of the same cardinal biological pathways that calorie restriction does."

For the study, published inwards the magazine Nature Communications, Seals too Pb writer Chris Martens, thence a postdoctoral boyfriend at CU Boulder, included 24 lean too salubrious men too women ages 55 to 79 from the Boulder area.

Half were given a placebo for half-dozen weeks, thence took a 500 mg twice-daily dose of nicotinamide riboside (NR) chloride (NIAGEN). The other one-half took NR for the outset half-dozen weeks, followed past times placebo.

The researchers took blood samples too other physiological measurements at the halt of each handling period.

Participants reported no serious adverse effects.

The researchers flora that 1,000 mg daily of NR boosted levels of simply about other chemical compound called nicotinamide adenine dinucleotide (NAD+) past times threescore percent. NAD+ is required for activation of enzymes called sirtuins, which are largely credited with the beneficial effects of calorie restriction. It's involved inwards a host of metabolic actions throughout the body, but it tends to refuse with age.

Research suggests that every bit an evolutionary survival mechanism, the trunk conserves NAD+ when subjected to calorie restriction. But solely of late stimulate got scientists begun to explore the sentiment of supplementing with so-called "NAD+-precursors" similar NR to promote salubrious aging.

"The sentiment is that past times supplementing older adults with NR, nosotros are non solely restoring something that is lost with aging (NAD+), but nosotros could potentially survive ramping upward the activity of enzymes responsible for helping protect our bodies from stress," Martens said.

The novel study also flora that inwards xiii participants with elevated blood pressure level or phase 1 hypertension (120-139/80-89 mmHg), systolic blood pressure level was near 10 points lower afterward supplementation. H5N1 drib of that magnitude could interpret to a 25 per centum reduction inwards midpoint railroad train on risk.

"If this magnitude of systolic blood pressure level reduction with NR supplementation is confirmed inwards a larger clinical trial, such an number could stimulate got wide biomedical implications," the authors note.

Ultimately, the authors say, such CR-mimicking compounds could render an additional option--alongside the dietary changes too practise currently recommended--for people whose blood pressure level is non yet high plenty to warrant medication but who are nonetheless at run a peril for a midpoint attack.
They stress that the study was small-scale too "pilot inwards nature."

"We are non able to brand whatsoever definitive claims that this chemical compound is rubber or going to survive effective for specific segments of the population," said Martens, forthwith an assistant professor at the University of Delaware. "What this newspaper provides us with is a actually proficient stepping rock for hereafter work."

Martens too Seals stimulate got applied for a grant to bear a larger clinical trial looking specifically at the affect of NR supplementation on blood pressure level too arterial health. Martens is also launching a split upward trial looking at the affect NR has on older adults with mild cognitive impairment, a precursor to Alzheimer's disease.
