Hemp oil comes from hemp seeds and contains no THC, so it won't get you high—but it does deliver omega fatty acids, protein, and minerals your body needs daily

Hemp oil (also called hemp seed oil) is pressed from the seeds of the hemp plant. It's a food, not a drug. The seeds contain little to no THC—the compound that produces a high—so you're getting nutrition, not intoxication. The oil itself is pale green, nutty-tasting, and works as a cooking ingredient, salad dressing, or supplement you take by the spoonful.

What makes it worth using is the fatty acid profile. Hemp oil is roughly 80% polyunsaturated fat, split between omega-6 and omega-3 in a ratio close to what some nutrition research suggests is optimal. It also contains gamma-linolenic acid (GLA), a compound found in few other foods. Beyond fat, hemp seeds deliver plant protein, magnesium, phosphorus, and zinc—nutrients most people don't get enough of.

Key Takeaways

  • Hemp oil is high in omega-3 and omega-6 fatty acids, which support heart and brain function and reduce inflammation in the body.
  • A typical serving is one to three tablespoons daily, either drizzled on food or taken straight, and it works best stored in a cool, dark place to prevent the oils from breaking down.
  • Hemp oil has a low smoke point (around 330°F), so it's better for drizzling, dressing, or blending into smoothies than for cooking at high heat.
  • The taste is nutty and earthy; if you dislike it straight, mixing it into yogurt, oatmeal, or salad dressing makes it easier to consume regularly.
  • Hemp oil is not the same as CBD oil or cannabis oil—those are extracted from different plant parts and have different compounds and effects.

The Omega Fatty Acids and Why They Matter

Your body cannot make omega-3 and omega-6 fatty acids on its own, so you have to eat them. These are called essential fatty acids. They're involved in reducing inflammation, supporting heart rhythm, building cell membranes, and helping your brain function. Most people get plenty of omega-6 from vegetable oils and processed foods, but omega-3 is harder to come by unless you eat fish regularly or use seeds and oils like hemp, flax, or chia.

Hemp oil gives you both in one source. A single tablespoon contains roughly 2.6 grams of omega-3 and 8 grams of omega-6. The ratio matters because too much omega-6 relative to omega-3 can tip your body toward inflammation. Hemp's ratio is closer to balanced than most plant oils, which is why it shows up in anti-inflammatory eating patterns. If you already eat fatty fish two or three times a week, hemp oil adds to that benefit rather than replacing it. If you don't eat fish, hemp oil becomes a practical way to get omega-3 without supplements.

How to Store and Use Hemp Oil Daily

Hemp oil goes rancid faster than many other oils because of its high polyunsaturated fat content. Buy it in a dark glass bottle—not clear plastic—and store it in a cool, dark cupboard or the refrigerator. Once opened, most bottles last two to three months in the fridge, sometimes less at room temperature. If it smells musty or off, throw it out. Rancid oil loses its nutritional value and can upset your stomach.

The simplest way to use it is to drizzle one to three tablespoons over finished food: salads, soups, oatmeal, yogurt, or roasted vegetables. You can also blend it into smoothies, mix it into salad dressing, or stir it into hummus. Do not cook with it. Hemp oil's smoke point is around 330°F, which is too low for frying or baking. Heat breaks down the omega fatty acids you're trying to get, so save it for cold or room-temperature dishes.

If you dislike the taste straight, start with a teaspoon mixed into something flavorful rather than a full tablespoon. Your palate adjusts over time, and many people find they enjoy the nutty flavor once they've had it a few times. Consistency matters more than the amount, so a teaspoon daily is better than a tablespoon once a week.

Hemp Oil Versus CBD Oil and Other Hemp Products

Hemp oil and CBD oil are not the same thing, and the confusion is common. Hemp oil comes from the seeds and contains no CBD. CBD oil is extracted from the leaves, flowers, and stalks of the hemp plant and contains cannabidiol, a compound that interacts with your nervous system. CBD oil is marketed for anxiety, pain, and sleep; hemp oil is a food source of omega fatty acids and minerals.

Cannabis oil and hemp oil are also different. Cannabis oil is extracted from the cannabis plant (which may contain THC) and is not legal in all states. Hemp oil is legal everywhere in the United States because it comes from seeds, which contain no controlled compounds. When you buy hemp oil at a grocery store or health food shop, you're buying a food product, not a supplement or drug.

What the Research Shows About Hemp Oil and Inflammation

Studies on hemp oil are limited compared to research on fish oil or flax, but the evidence that exists points in a consistent direction. A 2020 review in the journal Nutrients found that hemp seed oil reduced markers of inflammation in people with high cholesterol. Another small study showed that people who consumed hemp seed oil for 12 weeks had lower blood pressure and improved cholesterol ratios compared to a control group.

The mechanism is straightforward: omega-3 fatty acids reduce the production of inflammatory molecules in your body. Hemp oil delivers omega-3 in a form your body can use directly, unlike some plant sources (like flax) where your body has to convert the omega-3 first, and conversion is inefficient. This doesn't mean hemp oil is a cure for inflammation or disease—it means it's a food that supports the anti-inflammatory processes your body runs naturally.

If you have a bleeding disorder or take blood thinners, talk to your doctor before adding hemp oil regularly. Omega-3 fatty acids have mild blood-thinning effects, and combining them with medication can increase bleeding risk. For most people, hemp oil is as safe as any other food oil.

Choosing and Buying Hemp Oil

Look for cold-pressed hemp oil in a dark glass bottle. Cold-pressing means the seeds were squeezed without heat, which preserves the omega fatty acids and other nutrients. Brands that list the harvest date or expiration date are more transparent than those that don't. Organic certification is available but not required; conventional hemp oil is safe, though organic means the seeds weren't treated with synthetic pesticides.

Price varies widely. A 16-ounce bottle typically costs between $12 and $25, depending on the brand and whether it's organic. Buying from a grocery store or established health food retailer is safer than buying from an unknown online seller, because you can see the bottle and check the date. If a bottle is very cheap or the label looks poorly printed, it's worth skipping.

Some brands mix hemp oil with other oils or add flavoring. Read the ingredient list: if it says "hemp seed oil" and nothing else, that's pure hemp oil. If it lists other oils or flavorings, you're getting a blend. Neither is wrong, but pure oil gives you the full nutritional profile without guessing what else is in it.

Combining Hemp Oil With Other Foods for Better Absorption

Fat-soluble vitamins and compounds are absorbed better when eaten with fat. Since hemp oil is fat, it actually helps your body absorb fat-soluble vitamins from other foods you eat at the same meal. Drizzling hemp oil over a salad with leafy greens means you absorb more of the vitamin K and other nutrients from the greens. Adding it to a smoothie with avocado or nut butter increases the total fat content and improves absorption of any fat-soluble compounds in the smoothie.

Pairing hemp oil with foods that contain vitamin C—like citrus, tomatoes, or bell peppers—may also help your body absorb iron from plant sources in the same meal. This is especially useful if you eat a plant-based diet and rely on seeds, legumes, and leafy greens for iron. The combination doesn't create a drug-like effect; it's just how your digestive system works when multiple nutrients are present together.

Frequently Asked Questions

Will hemp oil show up on a drug test?

No. Hemp oil contains no THC or CBD, so it will not trigger a positive result on any standard drug test. Drug tests look for THC metabolites, which hemp seeds do not contain. You can use hemp oil without any concern about testing.

Can I cook with hemp oil or add it to hot food?

You can add it to hot food after cooking—for example, drizzle it over hot soup or roasted vegetables right before eating. Do not heat it on the stove or use it for frying. Heat damages the omega fatty acids, which is the main reason to use it. Save cooking oils like olive or avocado oil for high-heat cooking.

How long does it take to notice a difference from hemp oil?

Hemp oil is a food, not a medication, so there's no sudden effect. If you're using it to support heart health or reduce inflammation, consistent use over weeks or months is what matters. Some people report better digestion or skin within a few weeks; others notice nothing obvious but benefit from the nutrients anyway.

Is hemp oil safe for kids?

Yes. Hemp oil is a food with no psychoactive compounds, so it's safe for children in normal food amounts. A teaspoon mixed into a child's smoothie or drizzled on their food is fine. It's no different from giving them any other seed oil.

Can I take hemp oil if I'm pregnant or breastfeeding?

Hemp oil is a food and is safe during pregnancy and breastfeeding. Omega-3 fatty acids are actually important for fetal brain development and infant nutrition. Use it as you would any other food oil. If you have specific health concerns, check with your doctor, but hemp oil itself is not a risk.
