TJ Dillashaw has implemented strict measures to avoid plastic in his daily life, a practice he has maintained for several years. He refuses to drink from plastic bottles and has created his company's beverage product in aluminum bottles. At home, he has installed reverse osmosis systems in his shower, toilet, and sinks, and drinks only reverse-osmosis filtered water. When traveling, he stops at stores like Whole Foods or Sprouts to purchase glass-bottled water such as Mountain Valley. Dillashaw regularly tests his urine and consumes glutathione to help eliminate heavy metals and plastic from his body. He expressed frustration about finding a coffee machine without plastic tubing, noting it is nearly impossible to find one that does not use plastic in its lining.
Former UFC bantamweight champion TJ Dillashaw has spoken publicly about an extensive regimen he has built around avoiding plastic exposure in his everyday life, a practice he says he has maintained for several years.
Dillashaw, 40, holds an 18-5-0 professional record and remains one of the most accomplished fighters in bantamweight history. The orthodox striker stands five-foot-six with a 67-inch reach and built his reputation on high-volume, technically sharp striking, averaging 5.09 significant strikes landed per minute across his career at 41 percent accuracy, while also contributing on the grappling side with 1.56 takedowns per 15 minutes.
Away from competition, Dillashaw has channeled a similar detail-oriented mindset into his approach to health and environmental toxins. He refuses to drink from plastic bottles and has designed his own beverage product to come in aluminum packaging as a direct result of that stance. At home, he has installed reverse osmosis filtration systems across his shower, toilet, and sinks, and drinks exclusively reverse-osmosis filtered water. On the road, he makes stops at retailers such as Whole Foods or Sprouts to source glass-bottled options like Mountain Valley water.
His protocol extends further. Dillashaw says he regularly tests his urine and uses glutathione supplementation specifically to help his body clear heavy metals and plastics. He also described the difficulty of sourcing a coffee machine free of plastic tubing, calling it a near-impossible task given how widely plastic is used in the internal lining of such appliances.
Why it matters
- Dillashaw's approach reflects a growing conversation in combat sports around environmental toxin exposure and long-term athlete health.
- His decision to build a beverage product around aluminum packaging ties his personal philosophy directly to his business interests.
- The detail and consistency of his regimen — home filtration, travel adjustments, supplementation, and regular testing — illustrates how far some athletes are willing to go outside the gym to manage their physical condition.
