Biohacking pioneer Dave Asprey recently praised vitamin C as a nutritional powerhouse, highlighting its wide-ranging benefits in a post on X that sparked both interest and debate.

“Vitamin C has superpowers,” Asprey posted on X. “It’s essential for collagen production, it boosts your immune system, protects your DNA, regulates neurotransmitters, and our body can’t make it on its own.”

Asprey outlined five key advantages of vitamin C, describing it as essential for collagen production to support skin, hair, nails, and joints. He also pointed to its role in boosting the immune system, protecting DNA from oxidative damage, and regulating neurotransmitters such as dopamine and norepinephrine. Asprey emphasized that vitamin C is a vital nutrient humans must obtain through diet or supplements.

The post aligns with scientific findings from institutions like the Mayo Clinic and PubMed, which support vitamin C’s antioxidant properties and its role in immune function and neuroprotection. Asprey encouraged his followers to explore biohacking strategies for improved health, reinforcing themes central to his work at Upgrade Labs and his bestselling books.

Asprey’s remarks, however, drew mixed reactions. One commenter warned that excessive vitamin C intake may convert to oxalates, which can increase the risk of kidney stones or even cancer. This concern reflects ongoing scientific scrutiny of high-dose supplementation, with research from Oregon State University’s Linus Pauling Institute noting potential risks.

Asprey’s post, part of his broader mission to promote health optimization, attracted both praise and skepticism, underscoring the complex and sometimes contentious nature of nutritional science.

Dave Asprey, widely known as the “Father of Biohacking,” is a four-time New York Times bestselling author and host of the Webby Award-winning podcast The Human Upgrade.
