Nightly Sleep takes three ingredients that individually have solid sleep-quality data and puts them in a single pre-bed packet at the doses the protocol is actually built around. Magnesium L-Threonate raises brain magnesium. Apigenin, a flavonoid found in chamomile, binds the same GABA receptors that mediate calm. L-Theanine, from tea leaves, blunts the mental-noise side of falling asleep.
There is no melatonin here. Melatonin down-regulates its own receptors with continued use, which is why long-term users often notice it stops working. This stack supports the neurotransmitter systems that regulate calm without relying on a hormone your body already makes.
