What creators think

Thomas Seyfried and Bryan Johnson are among the strongest advocates here, with Seyfried arguing — based on published research with Dominic D'Agostino — that hyperbaric oxygen selectively targets cancer cells when combined with a ketogenic diet, and Johnson reporting that 60 sessions wiped out inflammation and improved a blood vessel growth marker by 300%. Chris Williamson describes the subjective effect as more energizing than coffee or a cold plunge, while David Sinclair says there's good evidence for brain and blood flow benefits from pressure cycling and that he's personally observed wound healing improvements in others. Mark Hyman credits it, alongside ozone therapy, with helping him recover from serious illness within days, and Ross Edgley says it helped him avoid surgery after injury. These are creator-stated claims, not established facts, and the protocol details vary significantly across endorsers — Williamson specifically uses a hard-shell chamber at 2.2 ATA with a 20-on, 5-off oxygen cycling approach, which isn't what everyone here is describing.

"Muse stem cells were amazing. Then hyperbaric, red light therapy. I did everything, and that got me back to the start line ready for Iceland. I think without it I might have needed them reattached with surgery. So that's how good they we..."

Used alongside Muse stem cells and red light therapy

Coffee Direct rival
caffeinated energy drink

Chris says a 90-minute hyperbaric session beats coffee for the energy and alertness boost you feel afterward.

"Hyperbaric oxygen therapy — that hard shell at 2.2 ATA is so good. I don't know what is happening to make me feel the way that I do after I come out of a hyperbaric therapy, but it is 20 minutes on, 5 minutes off, 100% oxygen on the mask..."

Rated superior to coffee and cold plunge for energy/alertness

"Hyperbaric oxygen therapy — in favor. There's good evidence that cycling up and down in pressure is good for the brain and blood flow. I have done it myself and have seen improvements in wound healing in others. So yeah, in general it's a plus."

Used for: Personal recovery from mold illness Praised: Led to noticeable recovery within a couple of days vs: Used alongside ozone therapy

"For myself, what rescued me was getting ozone therapy and hyperbaric oxygen together. It sounds like a crazy treatment, but I was desperate and I did it and I was better within a couple of days starting to kind of recover."

"After 60 sessions of HBOT, we saw the most impressive results we've seen from any therapy to date. It wiped out inflammation in my body, improved a marker for blood vessel growth by 300%."
