The evidence in words
How much to take
2–6 g/day if trialing, often evening for stress.
Timing & separation
There are no strict timing conflicts on record for L-Ornithine; consistency matters more than the exact hour for most goals.
Why the dose is what it is
By supporting ammonia detoxification it may reduce exercise fatigue, and it modestly lowers cortisol/stress markers in small studies.
Bottom line
A minor anti-fatigue and stress option with thin evidence. Not essential.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
