First look at the Hemp Oil or tincture and divide the amount of CBD by the size of the package/bottle to find the concentration. Look for the total amount of CBD on the oil’s package listed in milligrams. Then look for the size of the container, which is usually near the bottom and listed in milliliters. Take the lowest dose of CBD oil recommended by the manufacturer. Figuring out the right dose can take a little trial and error. Gradually increase the amount until you find the dose that’s effective for you. Administer the dropper with the oil under your touch for 60-90 seconds before swallowing it. This allows for maximum absorption.
