Hemp oil, most commonly referring to hemp seed oil, is a nutrient-rich oil pressed from the seeds of the hemp plant. It contains essential fatty acids, vitamin E, and plant sterols but virtually no CBD or THC. This distinction matters because “hemp oil” on a product label can mean very different things depending on what part of the plant was used, and the difference affects what the oil actually does for your body.
Hemp Seed Oil vs. CBD Oil
The confusion between these two products is widespread, and it’s partly by design. Some manufacturers label CBD extracts as “hemp oil” to sidestep regulatory scrutiny, while others sell plain seed oil with packaging that implies cannabinoid content. Here’s the straightforward difference: hemp seed oil comes from the seeds, while CBD oil comes from the flowers, leaves, and stalks of the hemp plant.
Hemp seeds contain no more than trace amounts of cannabinoids like CBD and THC. The oil pressed from them is a nutritional product, similar in category to flaxseed oil or olive oil. CBD oil, on the other hand, is extracted using solvents or CO2 and contains meaningful concentrations of cannabidiol. If you’re looking for cannabinoid effects (relief from anxiety, pain, or seizures), hemp seed oil won’t deliver them. If you’re looking for a cooking oil or nutritional supplement rich in omega fatty acids, that’s exactly what hemp seed oil is for.
Nutritional Profile
Hemp seed oil stands out among plant oils for its fatty acid balance. It has a 3:1 ratio of omega-6 to omega-3 fatty acids, which nutritional researchers consider close to ideal for human health. Many Western diets skew heavily toward omega-6 (ratios of 15:1 or higher are common), so hemp seed oil offers a way to get both essential fats in better proportion.
The oil also contains gamma-linolenic acid (GLA), an omega-6 fatty acid that behaves differently from the more common forms. Rather than promoting inflammation the way excess omega-6 typically can, GLA has anti-inflammatory properties. It’s relatively rare in food sources, which makes hemp seed oil one of the more practical ways to get it.
Vitamin E content is notable too. Hemp seed oil contains between 76 and 92 milligrams of tocopherols (the active form of vitamin E) per 100 grams of oil, putting it in the same range as soybean and sunflower seed oils. It’s also rich in phytosterols, plant compounds that structurally resemble cholesterol and can compete with it for absorption in your gut.
How It’s Made
Most quality hemp seed oil is cold-pressed. The process works the same way as cold-pressed olive oil: hemp seeds are fed into a mechanical press that crushes them under high pressure, squeezing out the oil without adding heat. Keeping temperatures low preserves the fatty acids and vitamin E, which degrade when exposed to high heat. The result is a greenish oil with a mild, nutty flavor. Refined versions lose some color and taste but have a longer shelf life.
Effects on Heart Health
The cardiovascular research on hemp seed oil is promising but still early. A clinical study found that taking 30 milliliters of hemp seed oil daily for four weeks reduced total plasma triglycerides and significantly improved the ratio of total cholesterol to HDL (the “good” cholesterol), both markers associated with lower coronary heart disease risk. A separate randomized trial found that hemp seed peptides could help regulate both systolic and diastolic blood pressure in adults with hypertension.
That said, results vary across studies, and much of the existing research comes from animal models or small human trials. The overall pattern suggests hemp seed oil’s combination of omega-3s, GLA, and phytosterols works on multiple fronts: improving lipid balance, reducing oxidative stress, and lowering inflammation. But it’s not a proven treatment for any cardiovascular condition at this point.
Skin Benefits
Hemp seed oil is widely used in skincare, both as a standalone facial oil and as an ingredient in moisturizers and serums. Its GLA content encourages new cell generation while calming inflammation, which makes it useful for conditions like acne, eczema, and psoriasis. In a controlled crossover study, participants with atopic dermatitis who consumed 30 milliliters of hemp seed oil daily over a 20-week period saw improvements in their skin symptoms.
The oil rates at zero on the comedogenic scale, meaning it’s unlikely to clog pores. That rating isn’t standardized across labs, so individual reactions vary, but hemp seed oil is generally considered one of the safer plant oils for acne-prone skin. It absorbs relatively quickly compared to thicker oils like coconut or castor, leaving less residue on the surface.
Cooking and Storage
Hemp seed oil has a smoke point of 330°F (about 165°C), which is low compared to oils like avocado or refined coconut. That rules it out for frying or high-heat sautéing. Heat breaks down its delicate fatty acids and creates off-flavors. It works best drizzled over salads, blended into smoothies, stirred into dips, or added to dishes after cooking.
Store it in the refrigerator after opening. The same polyunsaturated fats that make it nutritionally valuable also make it prone to oxidation. An opened bottle kept at room temperature can go rancid within a few weeks. Refrigerated, it typically stays fresh for several months. Look for dark glass bottles, which block light and slow degradation.
Typical Dosage
Most clinical studies have used 30 milliliters per day, which is roughly two tablespoons. That amount has shown measurable effects on blood lipids and skin health in trials lasting four to twenty weeks. There’s no official recommended dose, but two tablespoons is a reasonable starting point if you’re using it as a daily supplement. Some people start with one tablespoon to gauge how their digestion responds, since any concentrated oil can cause mild stomach discomfort in the beginning.
THC Content and Legal Status
Hemp seed oil is legal throughout the United States and contains negligible THC. The federal legal threshold for hemp products has traditionally been 0.3% delta-9 THC by dry weight, and hemp seed oil falls far below that. New federal rules taking effect in late 2026 will tighten the standard further, capping final hemp-derived consumer products at 0.4 milligrams of total THC per container. For hemp seed oil, which naturally contains only trace cannabinoids, this change is unlikely to cause any compliance issues. You won’t get high from hemp seed oil, and it’s extremely unlikely to trigger a positive drug test.
Who Should Be Cautious
Hemp seed oil is a food product with a strong safety profile, but its high polyunsaturated fat content means it can cause loose stools or mild digestive discomfort in some people, especially at higher doses. If you take blood-thinning medications, it’s worth noting that omega-3 fatty acids can have mild anticoagulant effects at high intakes, though this hasn’t been specifically studied with hemp seed oil. The key is not to confuse hemp seed oil with CBD oil when reading safety information. Most reported side effects you’ll find online (fatigue, appetite changes, drug interactions) come from CBD research and don’t apply to the seed oil.
