Robert F. Kennedy Jr.’s warning about mitochondria slipped in between the anti-vaccine junk science and the excoriation of pharmaceutical drugs as “the No. 3 killer in our country.” He was speaking in 2023 to Joe Rogan, elaborating on the dangers of Wi-Fi—which

Good Energy follows a typical wellness playbook: using a mixture of valid and dubious research to pin a slew of common health problems on one overlooked element of health—and advertising a cure. Among the culprits for our mitochondrial ravaging, according to the Meanses, are poor sleep, medications, ultraprocessed foods, seed oils, too many calories, and too few vitamins, as well as chronically staying in comfortable ambient temperatures. The Means siblings therefore recommend eschewing refined sugar in favor of leafy greens, avoiding nicotine and alcohol, frequenting saunas and cold plunges, getting seven to eight hours of uninterrupted sleep a night, and cleansing your life of environmental toxins. Some studies indeed suggest that mitochondrial function is linked with sleep and temperature, but they’ve all been conducted on cell cultures, organoids, or mice. According to Macleod, evidence suggests that diet, too, is likely important. But only one lifestyle intervention—exercise—has been definitively shown to improve mitochondrial health in humans.
The Meanses are riding a wave of interest in mitochondrial health in the wellness world. Earlier this year, the longevity influencer Bryan Johnson and the ivermectin enthusiast Mel Gibson both endorsed the dye methylene blue for its power to improve mitochondrial respiration; Kennedy was filmed slipping something that looks a lot like methylene blue into his drink. (Kennedy did not respond to a request for comment; the FDA has approved methylene blue, but only as a treatment for the blood disease methemoglobinemia.) AG1, formerly known as Athletic Greens, formulates its drinkable vitamins for mitochondrial health. Even one laser-light skin treatment promises to “recharge failing mitochondria.” The enzyme CoQ10 is popular right now as a supplement for mitochondrial function, as is NAD, a molecule involved in mitochondria’s production of energy. NAD IV drips are especially beloved by celebrities such as Gwyneth Paltrow, Kendall Jenner, and the Biebers. These supplements are generally thought to be safe, and some preliminary research shows that NAD supplementation could help patients with Parkinson’s or other neurodegenerative diseases, and that CoQ10 could benefit people with mitochondrial disorders. Patients whose symptoms are clearly caused or made worse by deficiencies in a specific vitamin, such as thiamine, can benefit from supplementing those vitamins, Mootha said. But little research explores how these supplements might affect healthy adults.

In Good Energy, as well as on her website and in podcast appearances, Casey Means promotes a number of supplements for mitochondrial health. She also recommends that people wear continuous glucose monitors—available from her company, Levels Health, for $184 a month—to help prevent overwhelming their mitochondria with too much glucose. (According to Macleod, glucose levels are only “a very indirect measure” of mitochondrial activity.) As with so many problems that wellness influencers harp on, the supposed solution to this one involves buying products from those exact same people.
At best, all of this attention to mitochondria could lead Americans to healthier habits. Much of the advice in Good Energy echoes health recommendations we’ve all heard for decades; getting regular exercise and plenty of fiber is good guidance, regardless of anyone’s reasons for doing so. Switching out unhealthy habits for healthy ones will likely even improve your mitochondrial health, Jaya Ganesh, a mitochondrial-disease expert at Icahn School of Medicine at Mount Sinai, told me. After all, “if you consistently beat your body up with unhealthy habits, everything is going to fall sick,” Ganesh said.
But the mitochondrial approach to wellness carries risks, too. For patients with genetically caused mitochondrial disease, lifestyle changes might marginally improve some symptoms, Ganesh said, but attempting to cure such conditions with supplements and a healthy diet alone could be dangerous. Means also calls out medications—including antibiotics, chemotherapy, antiretrovirals, statins, and high-blood-pressure drugs—for interfering with mitochondria. Macleod told me that statins really do affect mitochondria, as do some antibiotics. (The latter makes sense: Mitochondria are thought to have evolved from bacteria more than a billion years ago.) That’s no reason, though, to avoid any of these medications if a doctor has determined that you need them.
Read: America can’t break its wellness habit
And yet, a whole chapter of Good Energy is dedicated to the idea that readers should mistrust the motives of their doctors, who the authors say profit by keeping Americans sick. The book is less critical of the ways the wellness industry preys on people’s fears. Zooming in on mitochondria might offer a reassuringly specific and seemingly scientific explanation of the many real ills of the U.S. population, but ultimately, Means and MAHA are only helping obscure the big picture.
