There are 30 full droppers in every 1 oz. bottle of CBD, with the bioavailable equivalent of approximately over 5,000mg of CBD of a fat-based CBD product. Everyone’s body and needs are different. On average, bottles of our CBD tincture last about a month, give or take, depending on the user. Full spectrum CBD oil has an inverse tolerance, which means that less CBD is needed for the same results after the initial loading period for most people.
