Zion Herbals Gold Reserve 15ML Tincture Made from our 30% kratom extract but converted to a truly water-soluble form which has a higher bio availability than any other liquid extract on the market. This formula uses food grade natural solvents and a no heat extraction process that is proprietary and unique. Made in small batches on a craft scale. Each bottle contains 3 servings and comes with a dropper top. Each serving is equivalent to 5 grams of raw kratom leaf.
