Tinctures are the most popular way to ingest CBD. Although not all tinctures are the same. Some are made by mixing with CBD isolate with an edible oil, such as MCT oil. Some tinctures are made with CBD distillate, which contains not only CBD, but also the other canabinoids found in hemp, including THC. You can also purchase tinctures that are strictly liquid CBD isolate, which is the liquid form of CBD isolate.
The amount of CBD on the bottle is the amount found in the ENTIRE bottle, not the amount you will consume with one dose. For best results, taking a dropperful daily is recommended. It is also important to search reputable sites online to read about the possible positive effects of CBD.
