What it is
A daytime calm blend built around L-theanine (200 mg), with lemon balm (Melissa officinalis) leaf extract (600 mg) and magnolia bark extract standardized to honokiol (40 mg). L-theanine is the relaxing amino acid found in tea, and the formula is aimed at a settled, focused calm and a healthy cortisol response — without a sedated or flat feeling. Taken as two capsules once a day.
Why the evidence supports it
Each of the three actives has human calming research behind it: L-theanine is studied for promoting relaxed, alert brain-wave states and steadier cortisol under stress, lemon balm for easing feelings of stress in acute testing, and magnolia's honokiol for mood and calmness. There is also a 30-day, double-blind, placebo-controlled study on the Feel Calm blend itself reporting improvements in occasional anxiousness and mood measures. With L-theanine dosed in line with its studies, it is an evidence-based way to support the Mind's Regulate function — the nervous system's calm, steady baseline through a busy day. (Availability has come and gone, so check the current site.)
