Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — neurotransmitter production

Neurotransmitters like dopamine, serotonin, and GABA control mood, sleep, focus, and energy. When they fall out of balance, the effects can be wide-ranging — and testing is the first step to understanding why.

Dried urine testing is rapidly becoming the preferred method for neurotransmitter and hormone assessment — but collection timing is everything.
