well - no crude snacks - a white coffee that's actually peppermint ginger cinnamon cardamom orange(and lemon) peels' flour (or oil) ... aah yes and coffee (sometimes i forgot and then reminds from irregularly transparent outcome XD) + multiviamin + B-complex + C - letting the body to figure out what it lacks

Parameter	LM387(A)	КР538УН3А
ISUPPLY(mA)	10	5
USUPPLY(V)	30(40)	7.5
