The death of a young woman injected with NAD+ by an unlicensed doctor in the Bronx<\/a> to which she\u2019d entrusted her care is shining a light on the celebrity-favored boosting therapy.<\/p>\n

Assistant District Attorney Ethan Reisbaum said in Bronx Criminal Court early Tuesday that Elizabeth Baron, 27, \u201cimmediately went into cardiac arrest and later was pronounced dead\u201d Sunday after receiving an injection of Nicotinamide adenine dinucleotide at Luis Rojas Cabrera\u2019s Bereshit Lifestyle Center in Riverdale.<\/p>\n

It is unclear at this time whether NAD+ caused Baron\u2019s death, as autopsy and toxicology results from the Office of the Chief Medical Examiner are pending.<\/p>\n

Cabrera, 55, who billed himself as a \u201cM.D., Surgeon, Naturopath,\u201d is facing charges of reckless endangerment and unauthorized practice of a profession. He\u2019s been released without bail.<\/p>\n

So what is NAD+, and who buys into the youthful glow it claims to promise?<\/p>\n

What is NAD or NAD+?<\/p>\n

Levels of NAD+, which is produced by the body and crucial to cellular metabolism, \u201cis a feature of aging and may play a role in the process,\u201d according to one 2021 study by molecular biologist Nichola J. Conlon.<\/p>\n

The properties of NAD+ aren\u2019t limited to those in the human body, but \u201cchronically low NAD+\u201d has been \u201clinked to multiple hallmarks of aging\u201d and found in \u201caccelerated aging disorders and age-related disease states,\u201d the paper adds. However, it\u2019s worth noting that its author is the CEO and founder of Nuchido Laboratories<\/a>, which focuses on aging and sells an NAD+ supplement claiming to \u201creduce biological age.\u201d<\/a><\/p>\n

\u201cI haven\u2019t seen convincing evidence that they prolong lifespan in animal models, and I certainly wouldn\u2019t take any myself<\/a> until they\u2019d been proven to work, be safe and efficacious in a properly run, double-blind, placebo-controlled human trial,\u201d David Vaux, a professor and molecular biologist, told the Guardian in 2025.<\/p>\n

\u201cGiving these supplements to already healthy or relatively healthy people is not going to do too much because your body\u2019s already got enough,\u201d\u00a0Nigel Turner, a professor who heads up the Victor Chang Cardiac Research Institute\u2019s Cellular Bioenergetics Laboratory, told the outlet.<\/p>\n

Both Vaux and Turner pointed to the \u201climited\u201d human studies, despite some promising findings in mice and preclinical models.<\/p>\n

Which famous faces have bought in, or at least claimed to?<\/p>\n

Kendall Jenner and Hailey Bieber extolled NAD boosters in a May 2022 episode of Hulu\u2019s \u201cThe Kardashians,\u201d<\/a> during the show\u2019s inaugural season. The supermodels received the substance through IV drips, though they\u2019re also available in pill-form and injections, with self-proclaimed hypochondriac Jenner, now 30, saying IV therapy \u201ccomfort[s] me.\u201d<\/p>\n

Bieber, now 29, joked at the time she intended to continue NAD for the rest of her days. \u201cAnd I\u2019m never going to age.\u201d<\/p>\n

Also in the bag for NAD+ are neuroscientist and podcaster Andrew Huberman, as well as \u201cbiohackers\u201d<\/a> Bryan Johnson and Gary Brecka<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"The death of a young woman injected with NAD+ by an unlicensed doctor in the Bronx to which…\n","protected":false},"author":2,"featured_media":301955,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[38],"tags":[128,262,263,266,85,267,607,9,24,264,12,63,261,265,129,131,130],"class_list":["post-301954","post","type-post","status-publish","format-standard","has-post-thumbnail","category-the-bronx","tag-bronx","tag-city","tag-county","tag-crime-and-public-safety","tag-latest-headlines","tag-local-news","tag-national-news","tag-new-york","tag-new-york-city","tag-new-york-county","tag-news","tag-nyc","tag-nyc-crime","tag-sub-county-region","tag-the-bronx","tag-the-bronx-headlines","tag-the-bronx-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/301954","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/comments?post=301954"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/posts\/301954\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media\/301955"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/media?parent=301954"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/categories?post=301954"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ny\/wp-json\/wp\/v2\/tags?post=301954"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
