Enig, jeg benytter det også inden sengetid :-D
One of the most important aspects of supplementing with ZMA is timing. I have always recommended taking it about 1 hour before bed and 1-2 hours after you eat. This will not only help to maximize its uptake and utilization, as clinical research confirms, but taking ZMA at this time of day will also enhance sleep quality.
