Knowledge base entries
4.6Ashwagandha
One of the best-studied adaptogens — standardized extracts have been shown in clinical trials to lower perceived stress and cortisol levels.
4.2Rhodiola Rosea (Golden Root)
An adaptogen traditionally used for mental and physical fatigue — research is promising, but less extensive than for ashwagandha.
4.4Lion's Mane
A functional mushroom studied for its effect on nerve growth factor (NGF) and cognitive function — human evidence is still preliminary.
4.5L-Theanine
An amino acid from tea leaves, most often paired with caffeine to smooth out its stimulating effect.
4.3Bacopa Monnieri
An Ayurvedic plant studied for long-term memory support — effects appear only after weeks of regular use.
4.6Melatonin
The hormone that governs your circadian rhythm — as a supplement it works better at resetting the body clock than as a classic 'sleeping pill.'
