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.)

These are lab markers where this product's ingredients have measured evidence in our citation library. This is not a claim that the product will change your results -- the research attaches to the ingredient, and what a marker means depends on the whole picture.

What people often notice when this marker sits outside the usual range
Higher: "Wired but tired" -- exhausted all day, then alert the moment the head hits the pillow.
Lower: Profound fatigue that is worst in the morning, and improves slightly through the day -- the reverse of the usual pattern.
Lab results are interpreted by a qualified clinician who knows your history. Nothing here diagnoses anything or replaces that conversation.
No product works in isolation
Every cell function above -- Sense, Exchange, Transform, Build, Maintain, Adapt -- needs the same broad base of optimal micronutrient levels running underneath it, all the time. MYND360 Feel Calm is not a stand-alone fix; it is one piece that plugs into that larger system. The foundation comes first, and this supports it.
