Magnesium helps regulate GABA, the brain's main calming messenger, and supports muscle relaxation. Yet roughly half of U.S. adults don't get enough from food.¹ In a placebo-controlled trial with older adults, daily magnesium improved sleep time, sleep efficiency and how quickly participants fell asleep.²* We use magnesium glycinate, a form bound to the amino acid glycine and known for being gentle on digestion.

L-theanine is an amino acid found naturally in tea leaves. Brain-wave (EEG) studies show it increases alpha activity, the pattern linked to calm, relaxed alertness, without causing drowsiness.¹ In a four-week randomized trial, healthy adults taking 200 mg a day reported better sleep quality and fewer stress-related symptoms than with placebo.²*

Reishi (Ganoderma lucidum) has been part of East Asian wellness traditions for centuries. Modern research focuses on its active compounds, beta-glucan polysaccharides and triterpenes. In laboratory studies, reishi extract increased total sleep time.¹ In a randomized trial of adults with persistent fatigue, eight weeks of reishi extract reduced fatigue and improved well-being.²* Human sleep research is still early, which is why reishi plays a supporting role in our blend.

Chamomile has been a bedtime tradition for centuries, and modern research helps explain why. Its flowers contain apigenin, a natural compound that binds to the same calming receptors in the brain that GABA acts on.¹ In a randomized trial, older adults taking chamomile extract for four weeks reported significantly better sleep quality than the control group.

Zinc is an essential trace mineral, and because the body can't store it, you need a little every day. It's involved in hundreds of enzyme reactions, and research points to a role in how the brain regulates sleep.¹ In a randomized trial with healthy adults, zinc-rich foods helped participants fall asleep faster and sleep more efficiently.²* A separate trial found zinc supplementation improved sleep quality in nurses working shifts.³*
