Ammonia is a waste product naturally produced in the body. It primarily comes from the digestion of protein by bacteria in the intestines.

Ammonia is a waste product naturally produced in the body. It primarily comes from the digestion of protein by bacteria in the intestines. If not processed by the liver and cleared from the body appropriately, excess ammonia can accumulate in the blood and pass from the blood into the brain, where it is toxic.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
