There are three main reasons carrier oils are used. Let’s cover each one in more detail.
Getting precise doses like 7.5 mg requires a precision scale and can’t be done accurately with the naked eye. We need special equipment for this, which simply isn’t realistic for most CBD users.
Absorbing fats in this way requires a series of enzymes in the digestive tract to prepare the fat molecules for absorption by breaking them down and turning them into micelles. When we eat fats, taste receptors in our mouth send signals to the digestive tract to get these enzymes ready.
What is a Carrier Oil?
Water-soluble compounds like most amino acids, sugars, and minerals can travel directly through the gut lining into the water-based blood. From here, they’re transported around the body. In the diagram above, water-soluble substances enter the red portion under the surface (the blood).
This is important because the body has two separate pathways for absorbing compounds into the body — a water-soluble pathway and a fat-soluble pathway. This all happens at the working unit of the intestinal tract known as the microvilli (pictured below).
The solution is to first dilute the CBD crystals into a carrier oil at a predictable amount — such as 100 mg, 300 mg, 600 mg, or 1000 mg CBD per bottle like you’ll find listed on most CBD oils.
There are many different carrier oils used in CBD products — coconut, MCT, palm, olive, avocado, hemp seed, sesame, and grape seed oil — each with their own set of positives and negatives.
Black seed oil (also known as black cumin seed oil, black onion seed oil, or kalonji) is derived from the seeds of Nigella sativa, a small flowering shrub native to eastern Europe, the Middle East, and western Asia.
Hemp seed oil (sometimes simply called hemp oil) is made, you guessed it, from hemp seeds, a superfood revered for its high concentration of plant proteins, vitamins, minerals, and more. It’s extremely rich in omega-3 and 6, and, while less studied than olive oil, has also been shown to have a unique range of health benefits.
CBD carrier oils can vary greatly, and each offers unique benefits and drawbacks. Keep reading for an in-depth look at some of the most popular CBD carrier oils on the market, including olive oil, MCT oil, hemp seed oil, and more.
Black Cumin Seed Oil
Carrier oils play a crucial role in CBD oils; chiefly, they help deliver the CBD, terpenes, and other beneficial compounds in cannabis extract into your body. Some of the most common carrier oils used in CBD products include:
If you’re planning on using CBD oil as a regular wellness supplement, you may opt for an olive oil or hemp seed oil-based oil, as these two carriers provide a whole range of beneficial properties that may benefit your entire body.
After discovering these seeds in the tombs of King Tutankhamun, scientists believe that black cumin seed has long played a central role in medicine and cooking. Studies suggest, for example, that black cumin seed oil is super rich in antioxidants  and may help relieve inflammation (when ingested or applied topically to the skin).
First and foremost, olive oil is extremely rich in oleic acid, a monounsaturated fat that has been shown to reduce inflammation  and, in some studies, even inhibit tumour cell proliferation  . Olive oil is also rich in omega-3 and 6 fatty acids, which are important components of cell membranes and precursors to many vital compounds that help regulate inflammation and blood pressure.
While many of these oils serve no purpose except to carry the CBD, others offer their own range of health benefits and advantages, potentially making them more desirable as carrier oils for any CBD product.
Second, there’s some evidence that grapeseed oil may have antioxidant properties that allow it to protect the skin. However, research into these benefits is still in its early stages, meaning we can’t yet draw any conclusions.
First, like several other common carrier oils, it’s rich in omega-6 fatty acids. More than 70% of the fat content of grapeseed oil is made up of heart-healthy polyunsaturated fats, resulting in a heart-friendly reputation that it very much deserves.
Another widely used carrier oil, avocado oil offers a range of unique advantages. Similar to MCT oil, avocado oil is highly bioavailable, meaning that your body can quickly and easily absorb the CBD content of the oil and deliver its effects.
Finally, there’s even some evidence that pomegranate seed oil may help to prevent the growth and proliferation of cancer cells. However, this research is still in its early stages, meaning we can’t yet draw any firm conclusions about pomegranate seed oil’s potential to fight disease.
