I purchased a bottle of tincture, I believe it's 2000 mg, 1 ounce (30ml) but I can't equate that into a mathematical formula of how many drops to take.
Possibly a questionable vendor because I ordered it before I saw the list of approved ones.. The directions on the box say it's not to be ingested at all, I think because of FDA regulations. The dosage is one dropper but there are no markings on the dropper.
Being cautious, I just took two drops under my tongue before bed on Monday, but no chande in sleep. Last night I took three drops under my tongue and still no change. What I'm looking for, is help with sleep so I'm hesitant to take it in the morning, because I'm sensitive to things and I don't want to be all wired out all day, I already have high morning cortisol and anxiety. Then again, I just may be one of the people that it doesn't work on. I will keep experimenting slowly and perhaps try ordering something different from one of the approved vendors.
