L-Theanine is an amino acid analog of the proteinogenic amino acids L-glutamic acid and L-glutamine and is found primarily in black, green, and white teas. L-theanine has been shown to have effects on glutamate receptor signaling, and nitric oxide production. L-theanine used in combination with caffeine can have significant effects on attention and working memory, and blood pressure.(Learn more)


Melatonin is a neurohormone secreted by the pineal gland in the brain. Melatonin levels are the gold standard for assessing the circadian rhythm, also known as your sleep-wake cycle. Melatonin supplementation is a powerful and safe way to modulate your biological clock: to consolidate your normal sleep cycle, to set your sleep cycle to a new timezone, and to enhance the efficiency of napping. Melatonin has also been linked to reducing inflammation, improving the efficacy of chemotherapy, and antioxidant activity. (Learn more)


Magnesium is an essential dietary mineral and the second most prevalent electrolyte in the human body. Magnesium has a diverse set of cognitive effects, including improvements in sleep, decreased stress, and increased attention.

Magnesium is essential for general health, as it helps to improve neural excitation, control blood pressure, and maintain glucose tolerance. Magnesium deficiencies are common in developed countries. Approximately 68% of adults in the US do not meet the recommended intake of magnesium, with 19% consuming less than half the recommended amount. Some degree of magnesium deficiency appears to affect a large percentage of adults. Magnesium deficiency is implicated in various disorders and diseases, namely attention deficit hyperactivity disorder. (Learn more)
