Can We Slow Down Aging?

Harvard Scientist Says He’s 20 Years Younger Than His Biological Age!

Renowned Harvard University geneticist David Sinclair recently made a startling assertion: Scientific data shows he has knocked more than two decades off his biological age. What’s the 49-year-old’s secret?

He says his daily regimen includes ingesting a molecule his own research found improved the health and lengthened the life span of mice. Sinclair now boasts online that he has the lung capacity, cholesterol and blood pressure of a “young adult” and the “heart rate of an athlete.”

Despite his enthusiasm, published scientific research has not yet demonstrated the molecule works in humans as it does in mice. Sinclair, however, has a considerable financial stake in his claims being proven correct, and has lent his scientific prowess to commercializing possible life extension products such as molecules known as “NAD boosters.”

His financial interests include being listed as an inventor on a patent licensed to Elysium Health, a supplement company that sells a NAD booster in pills for $60 a bottle. He’s also an investor in InsideTracker, the company that he says measured his age.

Discerning hype from reality in the longevity field has become tougher than ever as reputable scientists such as Sinclair and pre-eminent institutions like Harvard align themselves with promising but unproven interventions — and at times promote and profit from them.

Fueling the excitement, investors pour billions of dollars into the field even as many of the products already on the market face fewer regulations and therefore a lower threshold of proof.

“If you say you’re a terrific scientist and you have a treatment for aging, it gets a lot of attention,” said Jeffrey Flier, a former Harvard Medical School dean who has been critical of the hype. “There is financial incentive and inducement to overpromise before all the research is in.”

Elysium, co-founded in 2014 by a prominent MIT scientist to commercialize the molecule nicotinamide riboside, a type of NAD booster, highlights its “exclusive” licensing agreement with Harvard and the Mayo Clinic and Sinclair’s role as an inventor. According to the company’s press release, the agreement is aimed at supplements that slow “aging and age-related diseases.”

Further adding scientific gravitas to its brand, the website lists eight Nobel laureates and 19 other prominent scientists who sit on its scientific advisory board. The company also advertises research partnerships with Harvard and U.K. universities Cambridge and Oxford.
Some scientists and institutions have grown uneasy with such ties. Cambridge’s Milner Therapeutics Institute announced in 2017 it would receive funding from Elysium, cementing a research “partnership.” But after hearing complaints from faculty that the institute was associating itself with an unproven supplement, it quietly decided not to renew the funding or the company’s membership to its “innovation” board.

“The sale of nutritional supplements of unproven clinical benefit is commonplace,” said Stephen O’Rahilly, the director of Cambridge’s Metabolic Research Laboratories who applauded his university for reassessing the arrangement. “What is unusual in this case is the extent to which institutions and individuals from the highest levels of the academy have been co-opted to provide scientific credibility for a product whose benefits to human health are unproven.”

“Until about the early 1990s, it was kind of laughable that you could develop a pill that would slow aging,” said Richard Miller, a biogerontologist at the University of Michigan who heads one of three labs funded by the National Institutes of Health to test such promising substances on mice. “It was sort of a science fiction trope. Recent research has shown that pessimism is wrong.”

Mice given molecules such as rapamycin live as much as 20 percent longer. Other substances such as 17 alpha estradiol and the diabetes drug Acarbose have been shown to be just as effective — in mouse studies. Not only do mice live longer, but, depending on the substance, they avoid cancers, heart ailments and cognitive problems.

History is replete with examples of cures that worked on mice but not in people. Multiple drugs, for instance, have been effective at targeting an Alzheimer’s-like disease in mice yet have failed in humans.
“None of this is ready for prime time. The bottom line is I don’t try any of these things,” said Felipe Sierra, the director of the division of aging biology at the National Institute on Aging at NIH. “Why don’t I? Because I’m not a mouse.”

Research by Sinclair and others helped spark interest in resveratrol, an ingredient in red wine, for its potential anti-aging properties. In 2004, Sinclair co-founded a company, Sirtris, to test resveratrol’s potential benefits and declared in an interview with the journal Science it was “as close to a miraculous molecule as you can find.”

GlaxoSmithKline bought the company in 2008 for $720 million. By the time Glaxo halted the research in 2010 because of underwhelming results with possible side effects, Sinclair had already received $8 million from the sale, according to Securities and Exchange Commission documents. He also had earned $297,000 a year in consulting fees from the company, according to The Wall Street Journal.

At the height of the buzz, Sinclair accepted a paid position with Shaklee, which sold a product made out of resveratrol. But he resigned after The Wall Street Journal highlighted positive comments he made about the product that the company had posted online. He said he never gave Shaklee permission to use his statements for marketing.

Sinclair practices what he preaches — or promotes. On his LinkedIn bio and in media interviews, he describes how he now regularly takes resveratrol; the diabetes drug metformin, which holds promise in slowing aging; and nicotinamide mononucleotide, a substance known as NMN that his own research showed rejuvenated mice.

Of that study, he said in a video produced by Harvard that it “sets the stage for new medicines that will be able to restore blood flow in organs that have lost it, either through a heart attack, a stroke or even in patients with dementia.”In an interview with KHN, Sinclair said he’s not recommending that others take those substances.

“I’m not claiming I’m actually younger. I’m just giving people the facts,” he said, adding that he’s sharing the test results from InsideTracker’s blood tests, which calculate biological age based on biomarkers in the blood. “They said I was 58, and then one or two blood tests later they said I was 31.4.”

InsideTracker sells an online age-tracking package to consumers for up to about $600. The company’s website highlights Sinclair’s support for the company as a member of its scientific advisory board. It also touts a study that describes the benefits of such tracking, which Sinclair co-authored.

Sinclair is involved either as a founder, an investor, an equity holder, a consultant or a board member with 28 companies, according to a list of his financial interests. At least 18 are involved in anti-aging in some way, including studying or commercializing NAD boosters. The interests range from longevity research startups aimed at humans and even pets to developing a product for a French skin care company to advising a longevity investment fund.

He’s also an inventor named in the patent licensed by Harvard and the Mayo Clinic to Elysium, and one of his companies, MetroBiotech, has filed a patent related to nicotinamide mononucleotide, which he says he takes himself. Sinclair and Harvard declined to release details on how much money he — or the university — is generating from these disclosed outside financial interests. Sinclair estimated in a 2017 interview with Australia’s Financial Review that he raises $3 million a year to fund his Harvard lab.

Supplement Loophole?
The Food and Drug Administration doesn’t categorize aging as a disease, which means potential medicines aimed at longevity generally can’t undergo traditional clinical trials aimed at testing their effects on human aging. In addition, the FDA does not require supplements to undergo the same safety or efficacy testing as pharmaceuticals.
