How We Chose These Products

Products are ranked using our published scoring methodology — evidence strength, dose adequacy, ingredient form, third-party testing signals, value, and clean-label factors are weighted across the 5 criteria below. Commercial relationships do not determine our editorial rankings.

Omega-6:Omega-3 Ratio

25%

Hemp seed oil's signature benefit is its approximately 3:1 omega-6 to omega-3 ratio, considered optimal for human health. Products maintaining this ratio through gentle extraction score highest.

GLA Content

25%

Gamma-linolenic acid (GLA) is the key anti-inflammatory omega-6 in hemp seed oil. GLA converts to DGLA, which competes with arachidonic acid to reduce inflammatory eicosanoids.

Cold-Pressed / Organic Quality

20%

Cold-pressing preserves heat-sensitive fatty acids and prevents oxidation. Hexane-free extraction avoids solvent residues. Organic sourcing reduces pesticide exposure.

Third-Party Testing

15%

Independent testing verifies fatty acid profile, absence of heavy metals, and confirms no THC/CBD contamination. GMP certification ensures manufacturing quality.

Value per Serving

15%

Cost per softgel adjusted for dose and count. Higher-dose products (1400mg) and larger counts (180ct) offer better long-term value.

How to Choose

Hemp Seed Oil vs. CBD Oil: A Critical Distinction

Hemp seed oil and CBD oil are completely different products despite both coming from the Cannabis sativa plant. Hemp seed oil is pressed from the seeds and contains NO cannabinoids (no THC, no CBD). It is a nutritional oil valued for its fatty acid profile. CBD oil is extracted from the flowers, leaves, and stalks of hemp and contains cannabidiol. If you are looking for anti-inflammatory omega fatty acids and GLA, you want hemp seed oil. If you are looking for cannabinoid therapy, you want a different product entirely. Every product in this comparison is pure hemp seed oil with zero cannabinoid content.

Why the Omega-6:Omega-3 Ratio Matters

Most Western diets have an omega-6 to omega-3 ratio between 15:1 and 20:1, which promotes chronic inflammation. Hemp seed oil naturally provides approximately a 3:1 ratio, which researchers consider close to optimal for human health. This balanced ratio means hemp seed oil delivers omega-6 without the inflammatory excess found in corn, soybean, or sunflower oils. Look for products that specify cold-pressed extraction, as heat processing can damage these delicate fatty acids and alter the ratio.

GLA: The Anti-Inflammatory Omega-6

Gamma-linolenic acid (GLA) is what makes hemp seed oil special among plant oils. Unlike the pro-inflammatory omega-6s in most seed oils, GLA converts to DGLA (dihomo-gamma-linolenic acid), which competes with arachidonic acid and produces anti-inflammatory prostaglandins. Hemp seed oil typically contains 2-4% GLA by weight. A 2005 randomized controlled trial by Callaway et al. showed hemp seed oil significantly improved eczema symptoms, likely through this GLA pathway. Products from Manitoba Harvest also contain stearidonic acid (SDA), another beneficial fatty acid.

Cold-Pressed vs. Refined: Quality Indicators

Cold-pressed hemp seed oil retains its full fatty acid profile, natural vitamin E, and chlorophyll. Heat extraction or solvent (hexane) processing can degrade GLA and oxidize omega-3s. Look for 'cold-pressed,' 'hexane-free,' or 'virgin/unrefined' on the label. NOW Foods and DEVA both specify cold-pressed hexane-free processes. Piping Rock also uses cold-pressing despite its budget positioning. If a product does not specify its extraction method, it may use heat or solvent processing.

Dose and Serving Size

Clinical studies typically use 15-30mL (1-2 tablespoons) of liquid hemp seed oil daily, which translates to roughly 1000-3000mg in capsule form. Most products offer 1000-1400mg per softgel. At one softgel daily, you get a maintenance dose. For therapeutic purposes like eczema management (as in the Callaway 2005 study, which used 30mL daily), you may need 2-3 softgels. The 1400mg options from Carlyle and Piping Rock get you closer to therapeutic doses in fewer capsules.

Storage and Freshness

Hemp seed oil is rich in polyunsaturated fats that are susceptible to oxidation. Store softgels in a cool, dark place and use them within the expiration date. Softgels offer better oxidation protection than liquid hemp oil because the gelatin or cellulose shell limits air exposure. If your softgels develop an off smell or taste, they may have gone rancid. Refrigeration can extend shelf life, especially in warmer climates.

Frequently Asked Questions

Is hemp seed oil the same as CBD oil?

No, they are completely different products. Hemp seed oil is cold-pressed from hemp seeds and contains zero cannabinoids, meaning no THC and no CBD. It is a nutritional oil valued for its omega fatty acids and GLA. CBD oil is extracted from hemp flowers, leaves, and stalks and contains cannabidiol. All products in this comparison are pure hemp seed oil with no cannabinoid content.

Will hemp seed oil show up on a drug test?

No. Hemp seed oil contains no THC (the psychoactive cannabinoid that drug tests detect) and no other cannabinoids. It is a food-grade oil pressed from seeds only. Drug test concerns apply to full-spectrum CBD products, not hemp seed oil. However, always buy from reputable manufacturers to ensure no cross-contamination during processing.

What is GLA and why does it matter in hemp seed oil?

GLA (gamma-linolenic acid) is an omega-6 fatty acid that, unlike most omega-6s, has anti-inflammatory properties. Your body converts GLA into DGLA, which produces anti-inflammatory prostaglandins. Hemp seed oil typically contains 2-4% GLA. A 2005 randomized controlled trial found that dietary hemp seed oil improved eczema symptoms, likely through this GLA pathway ^[1]. Few common plant oils contain meaningful GLA amounts, making hemp seed oil unique.

What is the ideal omega-6 to omega-3 ratio?

Research suggests a ratio between 2:1 and 4:1 is optimal for reducing inflammation and supporting cardiovascular health. Hemp seed oil naturally provides approximately a 3:1 ratio, which falls right in this optimal range. For comparison, the typical Western diet has a ratio of 15:1 to 20:1, which promotes chronic inflammation. This naturally balanced ratio is one of hemp seed oil's primary nutritional advantages.

How much hemp seed oil should I take daily?

For general nutritional support, 1000-2000mg daily (1-2 softgels) is a standard maintenance dose. The Callaway 2005 eczema study used approximately 30mL of liquid hemp seed oil daily, which translates to roughly 2-3 softgels of a 1400mg product. Start with one softgel daily and increase gradually. Hemp seed oil is a food oil with a strong safety profile, so higher doses are generally well tolerated.

Should I choose softgels or liquid hemp seed oil?

Softgels offer better protection against oxidation (the sealed capsule limits air exposure), precise dosing, and convenience. Liquid hemp seed oil is more economical per gram and allows higher daily doses more easily, but it must be refrigerated after opening and used within weeks. For supplementation purposes, softgels are generally more practical. For cooking or adding to smoothies, liquid oil is better.

Can vegans take hemp seed oil supplements?

Most hemp seed oil supplements use gelatin softgels, which are not vegan. The DEVA Vegan Virgin Hemp Seed Oil Capsules in this comparison use a plant cellulose capsule shell, making them suitable for strict vegans. Alternatively, liquid hemp seed oil (sold in bottles) is inherently vegan. Always check the capsule material if vegan compliance matters to you.

Does cold-pressed really matter for hemp seed oil?

Yes, significantly. Hemp seed oil's key fatty acids (omega-3 ALA, GLA, and SDA) are polyunsaturated and sensitive to heat. Cold-pressing preserves these delicate fats, along with natural vitamin E and other micronutrients. Heat extraction or hexane-solvent processing can oxidize omega-3s and destroy GLA. Products labeled 'cold-pressed' and 'hexane-free' (like NOW Foods and DEVA) retain the full nutritional profile that makes hemp seed oil beneficial.
