Biohacker Bryan Johnson Turns His Urine Blue, But How?

Bryan Johnson, the tech entrepreneur known for spending millions each year on anti-aging methods, recently revealed that his urine has turned bright blue. He humorously compared the sensation to feeling “like I’m in Avatar.”

The vivid hue comes from methylene blue, a compound with historical medical uses now being explored by biohackers for potential mitochondrial and cognitive benefits.

Project Blueprint: The Million-Dollar Life Extension Plan

Johnson’s ongoing anti-aging quest—dubbed Project Blueprint—includes a strict daily routine involving a precise diet, light therapy, hormone tracking, intense physical treatments, and high-end supplements. He claims these habits give him the heart of a 37-year-old and the lung function of someone aged 18.

Why Methylene Blue?

Originally developed as a dye and medication, methylene blue is still used today to treat certain infections and blood-related conditions. Recently, it has gained traction in the biohacking world as a possible tool for boosting brain function and supporting energy production in cells.

Supporters believe it may improve mitochondrial health, sharpen memory, and even slow down the aging process. Although some early research shows potential, many scientists warn that the evidence is still very limited.

Safety First—or Should Be

Experts are quick to point out the risks. Methylene blue isn’t harmless—especially when taken in high doses or combined with certain medications. It can cause headaches, nausea, dizziness, and even serious side effects like serotonin syndrome in people taking antidepressants.

Doctors also warn that not all methylene blue products are created equal. Some online supplements are unregulated, which adds another layer of risk for those trying to follow Johnson’s path.

What It Means—for Biohacking and Beyond

Bryan Johnson’s blue urine may sound like a joke, but in the biohacking community, it’s serious business. It shows just how far some people are willing to go in the name of longevity, especially when they have the money to experiment with cutting-edge (and controversial) methods.

It also raises questions about how safe or ethical it is to publicly promote these practices. While Johnson’s transparency gives a behind-the-scenes look at his routine, it may also encourage people to try things their bodies aren’t ready for.

For now, the blue pee is just another chapter in Johnson’s headline-making life extension story. Whether it’s a breakthrough or just another trend, only time—and science—will tell.
