Carrier Oil
Also known as: Base Oil, Tincture Base Oil
A carrier oil is the edible plant oil, such as MCT, hemp seed, olive, or grapeseed, that hemp extract is dissolved in to make a CBD tincture, because CBD is fat-soluble and does not mix with water.
Raw hemp extract is thick, concentrated, and hard to measure. CBD is fat-soluble, so it dissolves into oil and not into water. Mixing the extract into a carrier oil does three jobs: it spreads the cannabinoids evenly through the bottle, it makes a dropper serving something you can actually count in milligrams, and it gives you something pleasant to hold under your tongue. The common choices are MCT oil (medium-chain triglycerides, usually from coconut), hemp seed oil, olive oil, and grapeseed oil.
The oil you pick changes the product. MCT is close to flavorless, stays liquid, and is shelf-stable. Hemp seed oil has a nutty, grassy taste and is its own ingredient, since it carries no CBD of its own. Olive oil tastes like olive oil and runs thicker, which can make drops harder to measure. Many brands say MCT absorbs more efficiently than longer-chain oils, and the general reasoning is that medium-chain fats are handled differently by the body. We read that as a reasonable explanation and not as a measured promise for any one bottle, and we have no head-to-head data to share.
We use organic coconut-derived MCT oil in our oral drops, with real essential oil for flavor in Fresh Mint and Peruvian Lime and none in Natural. We do not market them as nano CBD. The drops are hemp extract in MCT, taken under the tongue. Check the label for the carrier by name, and if a brand will not say what the base oil is, that is worth noting. The batch COA shows the cannabinoid content, and we post ours at /coas.

- MCT OilMCT oil — medium-chain triglycerides, derived from coconut or palm — is the most common carrier oil for CBD tinctures because it improves absorption.
- Hemp Seed OilHemp seed oil is pressed from hemp seeds and contains essentially no CBD or THC. It is NOT the same as CBD oil.
- BioavailabilityBioavailability is the percentage of a dose that actually reaches your bloodstream. CBD's bioavailability varies dramatically by delivery method.
- SublingualSublingual means 'under the tongue.' CBD oil held under the tongue absorbs through the rich blood vessels there, reaching the bloodstream in 15-45 minutes.
- TinctureA tincture is a liquid herbal extract, traditionally made by soaking plant material in alcohol. Modern CBD 'tinctures' usually use a fat-based carrier (MCT oil) instead.
