Tinctures are gaining in popularity because they are easy to use and appeal to nearly all demographics. Simply hold under your tongue, or add to any juice or smoothie. The CBD should enter your system within 15-45 minutes. Carrier oils such as MCT Oil can increase the bioavailability / absorption of CBD into our bloodstream by a factor of 3-4x when ingested, because cannabinoids dissolve in lipids. MCT oil has 6-9x more lipids than olive oil or hemp oil.
