What is hemp seed oil?

Hemp seed oil is oil cold-pressed from the seeds of Cannabis sativa. It is rich in polyunsaturated fats, especially linoleic acid (omega-6) and alpha-linolenic acid (omega-3).

Does hemp seed oil contain CBD or THC?

Hemp seed oil made from seeds typically does not contain cannabinoids like CBD or THC in meaningful amounts. Products can vary, so check the label and testing information if cannabinoid content matters to you.

What are the main benefits of hemp seed oil?

It provides essential omega-6 and omega-3 fatty acids that support general nutrition. It may also support skin hydration and has potential mild anti-inflammatory effects, though evidence varies by outcome.

How much hemp seed oil should I take per day?

Common supplemental amounts are about 15–30 mL per day. Start lower to assess tolerance, and consider total calorie and fat intake from your overall diet.

How should hemp seed oil be used in cooking?

It’s often used as a finishing oil in dressings or added to foods after cooking. To preserve its fatty acids and flavor, avoid high-heat cooking unless the product is specifically labeled as suitable for it.
