⚠ Does NOT provide EPA or DHA — still need fish/algae oil [1]
⚠ Do NOT cook with it — heat destroys PUFAs [1]
⚠ Label confusion: 'hemp oil' can mean seed oil (food) OR CBD extract [2]
ℹ️ Not obtained from food. Not applicable — this is not obtained from food in meaningful amounts; supplementation is the practical route.
🔬 Lab interpreter

⚕ For professionals — confirm ranges against your local laboratory.
Clinical verdict
Hemp seed oil provides a 3:1 omega-6:3 ratio with unique GLA + SDA — but does NOT contain EPA, DHA, THC, or CBD. A nutritious culinary oil (don't heat). NOT a marijuana product, NOT a CBD product, NOT a DHA source. 'Hemp oil' label confusion: seed oil (food) vs extract (CBD). Optimal EFA ratio theory is sound but clinical outcome data are lacking [1] [2].

3 Common questions
Does hemp seed oil contain THC or CBD? ▼
NO — hemp SEED oil is from seeds, which contain no cannabinoids. CBD/THC are in flowers and leaves. 'Hemp oil' on labels can be confusing — check if it's seed oil (food/nutrition) vs hemp extract (CBD product) [2].
Is hemp seed oil better than flaxseed oil? ▼
Different profiles. Hemp: 3:1 omega-6:3 + GLA + SDA. Flax: higher total ALA but no GLA or SDA. Both provide ALA but neither provides DHA. Hemp has a more balanced overall PUFA profile [1].
Will hemp seed oil show on a drug test? ▼
No — hemp seed oil contains no THC. However, some poorly processed hemp EXTRACT/CBD products may contain trace THC [2].
