There are no contraindications to combining Serpina Himalaya with tryptophan and GABA. These preparations do not interact with each other in a clinically significant way.

However, it is worth keeping a few hours between taking them, e.g. serpina in the morning (1/4 tablet), and tryptophan 300 mg and GABA 250 mg in the evening, as they have a calming effect and support sleep.

It should be remembered that both Serpina and tryptophan can lower blood pressure and affect the nervous system, so (especially at the beginning of the treatment) it is worth regularly measuring blood pressure and heart rate and observing whether excessive sleepiness, dizziness or pressure drops occur, which may indicate hypotension.
