FAQ
Questions, answered.
Closing the day. Two lemon-lime gummies half an hour before you want the evening to be over: 500 mg of Reishi 10:1, 100 mg of GABA and 60 mg of saffron, with no melatonin.
People whose evenings run on screens and to-do lists. Anyone who tried melatonin and hated the morning after. The ones who want a routine they can skip, not a schedule. And people who will not swallow a capsule.
No. None — not a low dose, not a gentle amount. That is the whole point of the jar: there is nothing to come off and no heavy morning.
Yes, and you can skip nights freely. There is nothing in it you have to stay on or taper off.
Two gummies, chewed, about half an hour before you want the evening to be over. No water needed. Do not exceed the stated daily portion.
You will not taste it. The gummy is lemon-lime. Saffron is here for what it is, not how it tastes — 60 mg of stigma extract a portion.
Not for children under 18, or during pregnancy or breastfeeding. If you take medication or are under medical care, talk to your doctor first. Keep out of reach of young children.
