Hemp seeds are a rich source of nutrients. Part of the hemp plant, these seeds are technically a nut that can be eaten raw or used to make milk, oil, cheese substitutes, or protein powder.
While related to the cannabis plant, hemp seeds have little to none of the psychoactive compound THC found in marijuana. For centuries the seeds have been used for oral and topical applications to treat and prevent certain health issues. A growing body of modern clinical research is backing up many of these claims.
Hemp seeds’ nutty flavor and versatility also make them a great substitute for the levels of protein, essential fatty acids, and other nutritional benefits found in meat and dairy products.
Hemp seeds can be:
- Eaten raw, roasted, or cooked
- Shelled as hemp hearts
- Cold-pressed to produce hemp seed oil
- Used for non-dairy hemp milk and hemp cheese
A 30 gram serving (three-tablespoons) of raw hemp seeds contains:
- Calories: 166
- Protein: 9.47 grams
- Fat: 14.6 grams
- Carbohydrates: 2.6 grams
- Fiber: 1.2 grams
- Sugar: 0.45 grams
Hemp seeds are also good source of:
Hemp seeds also contain high levels of omega-3 and omega-6 essential fatty acids.
Studies have shown that the ideal ratio for the fatty acids in hemp seeds is 3 to 1. At this ratio, these fatty acids help to support healthy cholesterol levels, immune system function, and may help regulate your metabolism.
Potential Health Benefits of Hemp Seeds
Hemp seeds are an excellent source of plant-based protein. They contain all nine essential amino acids, and research suggests that hemp’s protein content is well-absorbed by our bodies.
In addition to this protein load, hemp seeds history is tied to their potential health benefits. Many modern studies have backed up several of these claims.
Hemp seeds’ health benefits include:
Hemp seeds are a great source of magnesium, which helps regulate your heartbeat and is linked to the prevention of coronary heart disease. They also contain Linoleic acid, which one study found reduced participants’ cholesterol levels by 15% and may act to reduce blood pressure.
One of the omega-6 fatty acids in hemp seeds is gamma-linolenic acid (GLA,) which may have anti-inflammatory effects similar to drugs like ibuprofen. One study found a 75% reduction in arthritis-associated pain in participants after nine months of GLA supplementation.
Hemp oil can be used in cooking to add nutritional benefits to your meal, and it can also be applied topically to the skin. Studies have found that hemp seed oil can relieve the symptoms of eczema and improve dry or itchy skin.
Research is ongoing, but hemp seed oil’s antimicrobial and anti-inflammatory effects may also help to treat acne.
The ratio of omega-6 to omega-3 fatty acids in hemp seeds is the optimal level for nutritional benefit. This balance supports both heart and cognitive health and is often lacking in most diets..
Hemp seeds also contain plant compounds called terpenes. While research is ongoing, studies suggest that terpenes may help protect the brain and prevent tumor growth.
Potential Risks of Hemp Seeds
While the fat content in hemp seeds comes primarily from its healthy essential fatty acids, eat them in moderation to meet your recommended daily consumption of fat. High fat intake can also cause nausea or diarrhea.
Other things to consider before adding hemp seeds to your diet include:
Hemp seeds may interact with certain medications including anticoagulants.
Studies have shown that hemp seeds reduce blood clotting, which can interact with blood-thinner prescriptions.
There is not enough clinical research to show that hemp is safe either orally or topically for women who are pregnant or breastfeeding, so it is not recommended.
Hemp seed shells can contain trace amounts of THC, the active psychoactive compound in marijuana. People with a previous dependence on cannabis may consider looking for an alternative.
The fiber content in hemp seeds can cause digestive discomfort like bloating, nausea, or constipation in large amounts. Make sure to drink plenty of water when eating hemp seeds to help avoid gut problems.

The Health Benefits of Hemp Hearts
Just like chia and flax seeds, hemp hearts pack a punch of nutrition in just a few tablespoons. Here’s the low-down.
Over the last decade, chia and flax seeds have gone from hipster products hidden in the back of a Whole Foods to beloved pantry staples, all thanks to their portable size, versatility in flavor combos, and nutritional values. And it’s about time hemp hearts got the same kudos.
Derived from the Cannabis sativa plant, hemp hearts are actually just hulled or unshelled hemp seeds, and no, they don’t naturally contain CBD — the compound that can potentially ease anxiety and treat other health concerns — or THC — the chemical responsible for cannabis’ mind-altering effects, per the Food and Drug Administration. While hemp hearts do have an ever-so-slightly nutty taste and creamy texture, that’s not their main draw. “Just like chia seeds or flax seeds, you don’t recommend hemp hearts for the taste — you recommend them for the added nutrition,” says Keri Gans, M.S., R.D.N., C.D.N, a dietitian and Shape Brain Trust member. That’s not to say hemp hearts taste bad (some people may enjoy that added bit of nuttiness!), it’s just that their nutritional qualities are probably the primary reason you’ll want to add them to your diet.
In fact, the health benefits of hemp hearts run aplenty. They offer everything from nutrients that support bone and heart health and essential minerals for plant-based eaters, to muscle-building macronutrients. And luckily, there’s an abundance of creative ways to add them to your diet too. “Any way you’d use chia seeds or flax seeds, you can use hemp hearts,” says Gans. “Add them to your smoothies, oatmeal, yogurt, or salads.” You can even incorporate them into homemade cookies, muffins, bread, granola, and energy balls for a punch of nutrients.
If this quick rundown didn’t quite convince you to swap your chia seeds for hemp hearts, read up on all the benefits of these little seeds below.
They’re loaded with protein.
Hemp hearts may be small, but they sure are mighty. Three tablespoons of the hearts contain a whopping 9.5 grams of protein — three grams more than a single egg and nearly double that of chia seeds, according to the United States Department of Agriculture. In case you forgot everything from high school health class, protein helps support your immune cells, hair, skin, and importantly, muscles. Following a round of exercise, your body uses protein to repair damaged muscle fibers, which helps them become even stronger. Unsurprisingly, if you don’t get enough of it through your diet, you could suffer from muscle loss, weak hair and nails, or immune issues.
For the average woman following a 2,000 calorie diet, the USDA recommends scoring 46 grams of protein a day. Do a little math wizardry, and that means one serving of hemp hearts offers nearly 20 percent of your daily need. Admittedly, a three-tablespoon serving is a lot, so you might eat only half a serving — and thus get half the protein — in one sitting. But every little bit adds up, so add as many as you’d like to your post-workout smoothie, and you’ll be on your way to achieving those #gains.
They boast omega-3 fatty acids.
While fresh fish and seafood are typically the go-to sources for omega-3 fatty acids, hemp hearts deserve to be on the favorites list, as well. In just three tablespoons of hemp hearts, you’ll get more than double the daily recommended amount of alpha-linolenic acid, a type of omega-3 that your body can’t produce on its own — meaning they need to be obtained from your diet, according to the National Institutes of Health.
Omega-3 fatty acids help reduce levels of triglycerides (a type of fat linked with increased risk of heart disease), curb the buildup of plaque in your arteries (which can ultimately lead to a heart attack or stroke), and slightly lower blood pressure, per the U.S. National Library of Medicine.

They support good bone health.
Though it’s not the most glamorous benefit of hemp hearts, it is one of the biggest. Just three tablespoons of hemp hearts provide 210 milligrams of magnesium and 495 milligrams of phosphorus, which breaks down to a whopping 68 percent and 70 percent of your recommended daily allowances, respectively, for each of those nutrients.
ICYDK, “magnesium can help in the whole bone equation,” says Gans. “We always talk about calcium and vitamin D, but magnesium also plays a role in keeping our bones strong.” In fact, research has found that people who consume more magnesium have higher bone mineral density, which is essential in reducing the risk of fractures and osteoporosis (a condition that causes bones to become weak and brittle.)
Likewise, the primary function of phosphorus in the body is to help build and maintain your bones and teeth, according to the NLM. Along with calcium, this essential nutrient forms the tiny crystals that give bones their rigidity, and when dietary intakes of phosphorous are lacking for a prolonged period, bones can actually weaken, per the Linus Pauling Institute at Oregon State University.
They supplement nutrients for plant-based eaters.
Listen up, vegetarians, vegans, flexitarians, and any other all or mostly all plant-based eaters. Three tablespoons of hemp hearts contain 13 percent of the recommended daily allowance for iron, a mineral that’s used to make proteins in red blood cells that carry oxygen from the lungs throughout the body and to muscles. Without enough of it, less oxygen is moved throughout the body, which can cause gastrointestinal upset, weakness, tiredness, lack of energy, and difficulty concentrating, per the NIH. Not exactly a pleasant situation to be in.
Along with pregnant women and young children, plant-based eaters are at a greater risk than most humans for iron deficiency, says Gans. That’s because the iron in food comes in two forms, heme iron (found only in meats and seafood) and non-heme iron (found in plant foods, iron-fortified products, meats, and seafood). Since the body doesn’t absorb non-heme iron as well as heme iron, plant-based eaters need to consume nearly twice as much iron to get their fill, per the NIH. And luckily, these crunchy hemp hearts can help herbivores easily amp up their iron intake, says Gans.
They help your body convert food to energy.
You can thank the tiny seed’s thiamine and manganese content for this hemp heart benefit. Also known as vitamin B1, thiamine helps your body break down carbohydrates so they can be used as energy, explains Gans. It’s also essential for the growth, development, and function of the cells in your body, according to the NIH. Without enough of the nutrient, you can start to experience weight loss, reduced appetite, confusion, memory problems, muscle weakness, and heart problems, reports the NIH. But not to worry, you can snag 35 percent of your recommended daily allowance in just three tablespoons of hemp hearts. (Related: Why B Vitamins Are the Secret to More Energy)
What’s more, a three-tablespoon serving of hemp hearts boasts nearly 130 percent (!)) of the recommended daily allowance of manganese, a mineral that helps break down the starches and sugar you eat and process cholesterol, carbohydrates, and protein, per the NLM. The nutrient also helps support strong bones, blood clotting, and a healthy immune system. It’s the bundle of nutrients you never knew you needed.
