A 30-gram serving of hulled hemp seeds, about three tablespoons, delivers roughly 2,600 milligrams of omega-3, according to USDA FoodData Central. That is more, by raw weight, than the roughly 2,500 milligrams of omega-3 in a 100-gram fillet of raw farmed Atlantic salmon in the same USDA database.
The catch is what kind of omega-3 you are getting. Hemp's omega-3 is almost entirely alpha-linolenic acid, or ALA, the plant form. Salmon supplies EPA and DHA, the marine forms your body uses directly in the brain, eyes and cardiovascular system.
Why the plant form comes with an asterisk
ALA is one of two fatty acids your body cannot make on its own, which is why the Institute of Medicine set an Adequate Intake of 1.6 grams a day for men and 1.1 grams for women. A single 30-gram scoop of hemp seeds covers that daily target more than once over.
But your body has to convert ALA into EPA and DHA to unlock most of the benefits associated with fish. The National Institutes of Health's Office of Dietary Supplements notes that this conversion, which occurs mainly in the liver, is very limited, with reported rates of less than 15 percent, and conversion to DHA is typically lower than to EPA.

Harvard's Nutrition Source puts it plainly. The conversion is not efficient enough to rely on, and those long-chain omega-3s are best obtained directly from food sources like oily fish.
In practice, hemp seeds are a strong way to hit your ALA requirement. They are not a substitute for oily fish if EPA and DHA are what you are after.
The GLA angle that sets hemp apart from chia and flax
Hemp seeds carry something most other plant omega-3 sources do not, a meaningful dose of gamma-linolenic acid, or GLA. Neither chia nor flax supplies it in comparable amounts.
GLA is technically an omega-6 fatty acid, but a peer-reviewed review of hemp lipid profiles describes it as a metabolic intermediate that may modulate the immune and inflammatory system. Depending on the variety, GLA makes up 0.5 to 1.8 percent of hemp seed oil. USDA figures put the amount at roughly 400 milligrams per 30-gram serving.

The strongest human evidence for GLA comes from rheumatoid arthritis. A Cochrane systematic review concluded that GLA from evening primrose, borage or blackcurrant seed oil probably improves pain and may improve function, without raising side effects. Those trials used concentrated GLA supplements, not hemp seeds, and doses were far higher than what you would eat at breakfast. The takeaway for daily use is more modest. Hemp seeds add a small amount of a fatty acid with plausible anti-inflammatory effects, not a therapeutic dose.
What about the omega-6 to omega-3 ratio
Hemp seeds are often praised for a roughly 3-to-1 omega-6 to omega-3 ratio, which some nutrition scientists describe as favorable for inflammation balance. That framing is contested. Harvard's Nutrition Source states directly that the omega-6/omega-3 ratio is not a useful indicator of the healthfulness of a food or diet, pointing instead to total intake of each fat as what matters. So the ratio is a nice number to cite, but not a shortcut to a health claim.
How to actually eat them
A 30-gram serving, about three tablespoons, is a realistic daily amount. Sprinkled on oatmeal, blended into smoothies or stirred into yogurt, hemp seeds add about 150 calories, 9 grams of protein and comfortably clear the daily ALA target. They keep best refrigerated after opening because their high polyunsaturated fat content oxidizes quickly.
If you already eat oily fish twice a week, hemp seeds are a useful add-on rather than a swap. If fish is off the plate, combining hemp with other ALA-rich foods like walnuts, chia and flax gives your body more raw material to work with, even if the EPA and DHA conversion remains limited. People with a bleeding disorder or on blood thinners should talk to a doctor before adding large amounts of any omega-3 rich food to a daily routine.
