Hemp protein powder stands out as a top-tier vegan protein powder source, boasting a rich blend of minerals, healthy fats, fiber, and antioxidants. It’s crafted by grinding pressed hemp seeds into a fine powder, retaining nutrients and an earthy flavor through a less intensive processing method than many other protein isolates. High-quality hemp protein powder may appeal to those who value a plant-based, nutrient-rich, and sustainable diet. 

Many fit folks conveniently incorporate the best hemp protein powder into their daily training routines by blending it into smoothies, which can help elevate their protein intake to reap the benefits of protein powder, like bolstered muscle development, expedited post-workout recovery, and weight management. 

Nevertheless, while hemp protein powder offers an array of health benefits, it may not suit every dietary preference or lifestyle. As a registered dietitian nutritionist, I’ll delve into hemp protein powder benefits to help you decide if it suits your needs.

1. Hemp Is a Complete Protein

Hemp protein is a complete protein, which means it contains all nine essential amino acids (EAAs) that the body cannot produce by itself. EAAs are necessary1 for protein synthesis, muscle growth, wound healing, metabolism support, and mood regulation. Included in the EAAs are branched-chain amino acids (BCAAs), leucine, isoleucine, and valine, which are particularly important for muscle-building and recovery.


Hemp has relatively low levels of lysine2, important for the production of collagen, a protein that helps give structure to bones and skin. Therefore, it’s often mixed with pea protein or soy protein, plant-based protein powders higher in lysine, to provide a rich essential amino acid profile.

Furthermore, hemp protein is high in arginine, a conditionally essential amino acid required for the synthesis of nitric oxide. Nitric oxide is a signaling molecule that relaxes blood vessels and increases blood flow to the muscles, giving you an impressive pump. What’s more, increased nitric oxide production (arginine in particular) has been shown to help improve anaerobic and aerobic physical performance3

2. Provides Fiber

Hemp protein powder typically contains fiber, a carbohydrate most adults don’t consume enough of. Hemp seeds—from which hemp protein powder is derived—contain soluble and insoluble fiber. The grams of fiber still remaining in hemp protein powder vary depending on the brand.

Fiber aids in digestive health by promoting regular bowel movements and preventing constipation. Moreover, it offers a feeling of fullness (or satiety), which can help with appetite control and weight loss4 by reducing caloric intake. Beyond its digestive benefits, dietary fiber is known to support heart health5 by helping to reduce cholesterol levels and manage blood sugar levels.

Although fiber is an important nutrient, you’ll want to avoid increasing your intake too quickly because this can lead to uncomfortable gas and bloating. If the hemp protein you choose is fiber-rich, consider gradually easing into a full serving size to allow your gut to adjust.

3. May Be Easier to Digest

Research in the Journal of Agricultural and Food Chemistry6 indicates that 91 to 98% of ground hemp seed meal is digestible, which is comparable to casein protein (98%). Its superior digestibility means your body can actually absorb and utilize most of its amino acid content. Researchers believe that hemp is easily digested due to its high edestin content, the main type of protein in hemp seeds that’s easily broken down by the digestive enzymes.

Furthermore, hemp is not a common allergen. For individuals who have allergies to milk or soy, hemp protein can be a suitable and better-tolerated alternative to whey, casein, or even soy protein powders. People with milk or soy allergies may find hemp protein easier to digest and less likely to trigger allergic reactions.

4. It’s Sustainable 

Plant-based diets are generally considered more sustainable than diets that rely on animal products. Vegan protein powders—such as hemp protein—may require less resources than animal products, preserve biodiversity, and have a lower environmental impact.

Hemp is known for its relatively low water requirements, adaptability to different climates and regions, and ability to grow with minimal pesticide use. This makes it a resource-efficient crop in comparison to the production of other plant and animal products. 

Additionally, hemp has a carbon-negative impact on the environment7. This means that hemp cultivation and utilization can help remove more carbon dioxide from the atmosphere than it produces. By reducing our carbon footprint, we can help slow rising temperatures due to global warming. 

5. It’s Rich in Minerals and Antioxidants

Hemp seeds are a good source of minerals8 such as phosphorus, potassium, magnesium and calcium. These minerals are essential for bone health, nerve signaling, proper muscle function, and fluid balance in the body.

Moreover, hemp seeds contain molecules with antioxidant activity, including tocopherols and lignan derivatives8. These compounds are considered beneficial because of their ability to combat harmful free radicals and reduce oxidative stress, which can cause cell damage in the body, potentially contributing to improved health. 

In particular, their antioxidant properties may be beneficial9 in combating inflammation and reducing the risk of heart disease, diabetes, and certain cancers. 

6. Contains Heart-Healthy Fats

Eighty percent of the fat content of hemp seeds is from polyunsaturated fats, omega-6, and omega-3 fatty acids, which protect against heart disease, high blood pressure, and elevated cholesterol levels8. Because hemp powder is less refined than other protein isolates, it retains a higher fat content than most. 

Aside from cardiovascular benefits, the essential fatty acids remaining in hemp protein powder also supports cognitive function and brain development, reduces inflammation, and contributes to hormone regulation and a strong immune system.

7. Taste

Many consumers approve of the earthy, nutty taste of hemp protein powder. The taste will vary slightly depending on the brand and how it’s processed, but the earthy and nutty characteristics are typically consistent. Those who do find the taste too strong often deem it more palatable when blended into the best protein shakes, mixed into oatmeal, or added to baked goods.

Possible Hemp Protein Powder Side Effects

Hemp protein powder is generally safe, but may cause side effects for certain individuals. Due to the higher fiber content of hemp protein powder, some may experience gas, bloating, or diarrhea if they consume the full serving and aren’t accustomed to a high-fiber diet. 

RELATED: Does Protein Make You Poop?

Those with an allergy to hemp should avoid hemp protein powder. Allergic reactions to hemp can vary from mild symptoms like itchy eyes or a runny nose to more severe reactions.

Consult with your healthcare provider before using hemp protein powder if you are pregnant, breastfeeding, or if you have an existing medical condition, as it may not be safe in these circumstances. 

Despite being derived from the hemp plant (cannabis sativa), hemp protein powder contains only trace amounts of THC, the psychoactive compound found in marijuana, and won’t pose any concerns regarding drug tests.

Hemp Protein Powder Recommended Dosages

The recommended dietary allowance (RDA) for protein stands at 0.8 grams per kilogram of body weight10 and is the minimal amount of protein daily recommended for adults. Under these guidelines, a 150-pound person would need at least 55 grams of protein each day.

Nevertheless, various reputable organizations such as the Academy of Nutrition and Dietetics, American College of Sports Medicine, and International Society for Sports Nutrition suggest elevating daily protein intake to a range of 1.2 to 2.0 grams11 per kilogram of body weight to promote muscle growth, aid in post-workout recovery, and enhance performance. Following these recommendations, a 150-pound athlete would need between 82 to 136 grams of protein daily. 

RELATED: How Much Protein Do I Need?

Hemp protein powder contains slightly less protein than whey, casein, and pea protein powders. Each 30-gram serving contains approximately 15 grams of protein, depending on the brand.

While whole foods should always be your primary source of protein, adding hemp protein powder to your diet can be a convenient tool to increase your protein intake and support your health and fitness goals.
