WHY PM CAPSULES
3 ingredients that support better sleep and overnight recovery
Deeper sleep
+L-Theanine promotes relaxation and natural sleep onset without drowsiness or grogginess.
200mg L-Theanine increases alpha brain wave activity, promoting a calm-but-alert state that transitions naturally into restful sleep. Unlike sedatives, it supports your natural sleep architecture without morning grogginess.
Calmer evenings
+Trace-dose lithium orotate supports mood stability and reduces racing thoughts before bed.
At 400mcg, lithium orotate is a trace dose -- roughly 1/100th of prescription levels. Population studies show regions with naturally higher lithium in tap water have lower rates of mood disorders and neurodegenerative disease.
Joint recovery
+The PM dose of glucosamine sulfate supports overnight joint repair and reduces morning stiffness.
750mg glucosamine sulfate completes the 1,500mg daily clinical dose (split AM/PM for steady levels). Overnight, the body prioritizes repair -- glucosamine supports cartilage regeneration and reduces inflammatory markers in joint tissue.
Neuroprotection
+Lithium orotate increases BDNF and supports brain autophagy at safe, trace-level doses.
Trace lithium upregulates BDNF (brain-derived neurotrophic factor), promotes neuronal autophagy, and inhibits GSK-3 beta -- a key enzyme linked to neurodegeneration. These neuroprotective effects occur at doses far below therapeutic psychiatric use.
HOW TO TAKE
