The antiaging industry is booming, pulling in billions in investment and drawing the attention of both entrepreneurs and world leaders. But behind the glossy marketing and bold promises lies a heated scientific feud, one that pits pioneers of the field against their former students and rivals. At the heart of this debate is Leonard Guarente, an MIT biologist whose early research helped launch the modern longevity movement. As reported by The Wall Street Journal<\/em>\u2019s Amy Dockser Marcus, the battle over antiaging science is as much about ideas as it is about money and power.<\/p>\n\n\n\n

From Lab Discovery to Supplement Empire<\/h3>\n\n\n\n

Leonard Guarente began studying aging in the early 1990s, shifting his lab\u2019s focus after promising genetic results in yeast. His work helped spotlight a family of genes called sirtuins, which he believes play a key role in how we age. Guarente argues that sirtuins need a molecule called NAD to function, and as NAD levels decline with age, so does the body\u2019s ability to stay healthy.<\/p>\n\n\n\n

In 2014, Guarente co-founded Elysium Health, a company selling supplements designed to boost NAD levels and activate sirtuins. These supplements, which range from $40 to $60 a bottle, are marketed as science-backed tools to help people stay younger, longer. Guarente points to the seven Nobel laureates on Elysium\u2019s advisory board as proof of the company\u2019s scientific credibility.<\/p>\n\n\n\n

The Prot\u00e9g\u00e9 Who Became a Critic<\/h3>\n\n\n\n

One of the most outspoken critics of Guarente\u2019s theory is Matt Kaeberlein, a former Ph.D. student in his lab. While Kaeberlein once helped show that sirtuins could extend life in yeast, he now questions whether those results apply to humans. In 2011, he co-authored a paper challenging the idea that sirtuins meaningfully extend the lifespan of worms and flies.<\/p>\n\n\n\n

\u201cThere\u2019s no rock-solid clinical trial data showing these supplements work,\u201d said Kaeberlein, now CEO of Optispan, a healthcare tech company. He\u2019s currently leading a major study on rapamycin, a drug used in organ transplants, to test whether it can extend the lives of dogs and possibly, one day, humans.<\/p>\n\n\n\n

Guarente has brushed off such critiques, saying that scientists often defend their own pet theories. \u201cIn the aging field, people have their favorite theory,\u201d he said. \u201cIt drives a lot of critique of theories that are not yours.\u201d<\/p>\n\n\n\n

A Booming Industry With Blurry Boundaries<\/h3>\n\n\n\n

Whether you side with Guarente or his critics, there\u2019s no denying that the antiaging industry is exploding. According to Longevity.Technology, the field has attracted $55.7 billion in global investment over the past decade. Some in the field are now calling for faster regulatory pathways to approve antiaging treatments.<\/p>\n\n\n\n

Political support is also rising. Robert F. Kennedy Jr., now head of Health and Human Services, has said he follows an antiaging regimen. His proposed deputy, Jim O\u2019Neill, previously led a nonprofit that funds longevity research.<\/p>\n\n\n\n

Still, critics warn that many products in the marketplace are being promoted before there\u2019s enough evidence they work. Clinical studies are often small and short-term. While consumers see ads citing scientific studies, the actual science is still evolving and sometimes conflicting.<\/p>\n\n\n\n

Former Allies, Now Competitors<\/h3>\n\n\n\n

David Sinclair, another former student of Guarente, also built a reputation on sirtuin research and helped co-found Sirtris Pharmaceuticals, a company that was later bought by GSK for $720 million. But that effort stalled after safety concerns, and GSK shut it down.<\/p>\n\n\n\n

Today, Sinclair is part of Metro International Biotech, which is working on NMN, a molecule similar to NAD. Metro hopes NMN will be approved as a drug to treat age-related diseases like Alzheimer\u2019s. That has created new conflict with Elysium, which sells NMN as a supplement, a practice the FDA has challenged.<\/p>\n\n\n\n

Sinclair has said he supports access to both supplements and drugs, but only if they\u2019re proven to be safe and effective. Guarente, for his part, argues that Metro\u2019s push to restrict NMN supplements is more about profits than public health.<\/p>\n\n\n\n

Despite these clashes, Guarente and Sinclair still collaborate on Galilei Biosciences, another company aiming to develop drugs based on sirtuins.<\/p>\n\n\n\n

Is the Promise Real?<\/h3>\n\n\n\n

Not everyone is ready to give up on sirtuins or NAD. Eric Verdin, head of the Buck Institute for Research on Aging, has spent more than 25 years studying them. While he agrees the science is complex, he says sirtuins remain promising targets.<\/p>\n\n\n\n

\u201cThere is no magic pill,\u201d Verdin said. \u201cEven though we all would love the idea that something magical could stop you from aging.\u201d<\/p>\n\n\n\n

Guarente remains undeterred. Elysium is running a long-term study involving 25,000 people to track how lifestyle, supplements, and genetics affect aging. Early research shows NAD levels can be raised in the short term, but whether that translates into living longer is still unknown.<\/p>\n\n\n\n

Guarente believes the field is slowly building toward stronger evidence. He points to studies showing that people who live past 100 often carry mutations in sirtuin genes. His hope is that targeting those genes could one day lead to therapies that truly delay aging.<\/p>\n\n\n\n

\u201cThis is a little more complicated than inventions that have led to progress,\u201d Guarente said. \u201cThe automobile is so tangible. It speaks for itself. This does not speak for itself. It needs a spokesperson.\u201d<\/p>\n\n\n\n

In today\u2019s crowded marketplace, it also needs clarity, rigorous evidence, and perhaps most of all, trust.<\/p>\n","protected":false},"excerpt":{"rendered":"
