One full dropper (1mL) contains 16 mg CBD and is marked at each quarter mL for easy dosing. For best results, shake well and place desired dose under your tongue and wait 30- 60 seconds before swallowing. The effects of CBD can be highly individual. To find your ideal dose, start with a lower dose and increase as necessary. CBD oil can also be applied topically (try adding to your favorite moisturizer). Store at room temperature out of direct sunlight.
