The formula
Tryptophan Calm Chews, and why it is built this way
L-tryptophan is the precursor to serotonin, but it only converts if B6 and magnesium are present and if it is taken without competing large neutral amino acids — which is why this formula pairs it with a carbohydrate carrier and B6 rather than selling tryptophan alone.
No 5-HTP — the combination with SSRIs is a genuine risk we avoid.
What it does
Three things you can expect
01
Supports serotonin production
The pathway behind mood and settle-down behaviour.
02
Cofactors included
B6 and magnesium are required for the conversion step.
03
For cats too
Half a chew for cats, crumbled over wet food.

From the household
What owners say
"Fireworks night: he slept through most of it instead of shaking in the bathroom."
"A vet visit without the trembling. That is enough for me."
"Not a sedative — he is still himself, just less on edge at the doorbell."
Questions
Before you buy
Can I combine this with the Calming Chews?
Pick one. Both raise serotonergic tone and stacking them is unnecessary.
Is tryptophan safe long term?
At these doses, yes. Very high doses have been linked to eosinophilic myositis in dogs, which is why we cap at 3 chews.
Why does it say 'with food' on the tub but 'empty stomach' here?
A small amount of carbohydrate improves uptake; a full meal introduces competing amino acids. Give it with a biscuit, not dinner.
