Dr. Stewart's notes on how this formula works and who it's for.

How It Works

Melatonin signals your brain that it's night.*

GABA is the brain's main calming messenger.*

Liposomes are tiny bubbles made from sunflower lecithin that surround the ingredients to protect them.

Doctor's Formulation Rationale

Not everyone wants to swallow a capsule at bedtime, and some people need only a little help to fall asleep or occasionally need help going back to sleep during the night. This spray delivers a small, gentle dose of melatonin and GABA in liposomes, tiny bubbles made from sunflower lecithin that protect the ingredients. I added glutathione for antioxidant support overnight. Six pumps in the mouth before bed.
