These are things I use myself.

Not endorsements. Not affiliates. Just tools that sit at the intersection of physiology and performance.
Things that quietly affect the conditions under which clear thinking, recovery, and optimal function become more available.

Nothing here is essential. But each of it is considered.

Pure Ionic Water

Water quality affects cognitive clarity more directly than most people realise. This is Hydrogen-rich ionic water, what I use at home and what I recommend to clients who take the physiological side of performance seriously.

Oxygen Advantage®

Functional breathing is one of the most underused and most immediately effective levers in human performance. This is the methodology I'm trained in as an Advanced Instructor and the one I return to most consistently in my work.

Earthing

Recovery and nervous system regulation are the unsexy foundations of sustained high performance. Grounding - direct contact with the earth's surface - has a growing body of research behind its effect on inflammation, sleep, and cortisol. Simple. Overlooked. Worth knowing about.

Viome

Gut health and cognitive performance are more directly connected than most performance frameworks acknowledge. Viome offers precision testing that makes the invisible visible and actionable.

N1O1

Nitric oxide plays a direct role in cardiovascular function, circulation, and cognitive performance. This is the product I recommend to clients looking to support that system intelligently.

Scientific Sounds

Sound environments affect attention, focus, and nervous system state more than most people consciously notice. This is what I use for brain entrainment to enhance my sleep and flow states.
