Hemp Protein: A Complete Source Of Essential Amino Acids? (2025)

Hemp protein is a plant-based protein derived from the seeds of the Cannabis sativa plant. It is a high-quality vegan protein source that contains all nine essential amino acids, as well as fibre, healthy fats, minerals, and antioxidants. Hemp seeds are comparable to soybeans in terms of nutrition, and the protein content of whole hemp seeds can vary between 20 and 25% depending on the variety and environmental factors. Processing methods such as dehulling or oil fraction removal can increase the protein concentration in products like hemp seed meal to over 50%.

The protein in hemp seeds consists of two highly digestible globular types of proteins, edestin (60-80%) and 2S albumin, with edestin also being rich in essential amino acids. Hemp protein has a unique amino acid composition that includes cysteine-rich content and a high sulfhydryl (-SH)/disulfide (S-S) ratio, which can facilitate the development of new food materials.

While hemp protein does contain all the essential amino acids, there is some debate about the quality of the protein. Some studies suggest that hemp has relatively low levels of the essential amino acid lysine, making it a poorer option for this specific nutrient. Additionally, hemp protein has the lowest leucine content among plant-based proteins at 5.1%. However, hemp protein has a high digestibility factor, with 91-98% of hemp protein being digestible, which means the body can effectively use the essential amino acids it provides.

Hemp protein powder is a complete protein source, containing all nine essential amino acids

Hemp protein is derived from the seeds of the Cannabis sativa plant. The seeds are pressed to remove the oil, and the remaining seed meal is ground into a powder. This process means that hemp protein powder is less processed than other protein powders, which is a bonus for people who prefer minimally processed foods.

The protein in hemp seeds is made up of two highly digestible globular types of protein: edestin (60-80%) and 2S albumin. Edestin is also rich in essential amino acids. Hemp protein is more digestible than soy protein, with 91-98% of hemp protein being digestible.

However, hemp protein is low in the essential amino acid lysine, which is important for muscle-building. This means that while hemp protein powder is a complete protein source, it is not the best option for people looking to build muscle. Instead, hemp protein powder is a good choice for vegans and vegetarians who want to ensure they are getting enough protein, as well as other essential nutrients like fibre.

Hemp protein powder is highly digestible, with 91-98% of hemp protein being digestible

Hemp protein powder is highly digestible, with 91-98% of hemp protein being easily digestible by the body. This is due to the presence of the proteins edestin and albumin, which the body can break down quickly. In fact, hemp is more bioavailable than soy protein, which often contains trypsin inhibitors that interfere with digestion.

The digestibility of hemp protein is also influenced by processing methods. For example, heat treatment at temperatures above 80°C can improve the digestibility of hemp protein. However, it is important to note that heat processing can reduce the overall digestibility of hemp protein by about 10%. As a result, it is recommended to look for hemp protein powders made from cold-pressed seeds to ensure maximum digestibility.

The high digestibility of hemp protein means that the body can effectively utilise the essential amino acids present in hemp. This makes hemp protein a good choice for individuals looking to increase their protein intake and support various bodily functions, such as repair and maintenance.

In addition to its high digestibility, hemp protein powder offers several other nutritional benefits. It is a good source of fiber, unsaturated fats, antioxidants, and minerals such as phosphorus, magnesium, calcium, iron, manganese, zinc, and copper. These additional nutrients contribute to overall health and wellness, making hemp protein powder a well-rounded option for individuals looking to improve their nutritional intake.

While hemp protein powder is highly digestible and offers a range of nutritional benefits, it is important to note that it may not be the best option for individuals specifically seeking a high-quality protein source for muscle building. This is because hemp protein has lower levels of the essential amino acids lysine and leucine, which are important for muscle growth. Therefore, while hemp protein powder is a good choice for individuals looking for a well-rounded vegan or vegetarian protein option, those specifically focused on muscle building may need to consider alternative protein sources or supplements.

Hemp protein powder is rich in essential amino acids but falls short when it comes to lysine

Hemp protein powder is a plant-based protein derived from the seeds of the cannabis plant. It is a high-quality vegan protein that contains all nine essential amino acids, along with fibre, healthy fats, minerals and antioxidants. However, hemp protein falls short when it comes to the essential amino acid lysine.

Hemp seeds are comparable to soybeans in terms of nutrition. They are high in protein, low in carbohydrates, and rich in dietary fibre and unsaturated fatty acids. The seeds are processed to remove the oil, leaving a protein-rich seed meal that is ground into a powder. This powder has a distinctive earthy or nutty taste and a grittier texture compared to other protein powders due to its minimal processing.

Hemp protein powder contains the two highly digestible globular proteins, edestin and 2S albumin. Edestin, which accounts for 60-80% of hemp protein, is rich in essential amino acids. However, hemp protein has relatively low levels of the essential amino acid lysine, which is crucial for muscle-building. This makes hemp a poorer quality option for those seeking optimal levels of this specific nutrient.

According to Food and Agricultural Organization (FOA) standards, the levels of lysine in hemp protein are lower than the recommended levels for infants up to five years old. Nevertheless, the overall nutritive value of hemp protein remains good due to its higher levels of sulfur-containing amino acids compared to casein or soy. Additionally, other non-essential amino acids present in hemp, such as arginine, provide additional health benefits like cardiovascular support, immune function optimisation, and muscle repair.

While hemp protein falls short in lysine content, it stands out for its digestibility. 91-98% of hemp protein is digestible, surpassing the digestibility of other plant-based proteins. This is attributed to the presence of edestin and albumin, which the body can break down quickly. Furthermore, hemp protein does not contain the trypsin inhibitors found in soy protein, which can interfere with digestion.

In summary, hemp protein powder is a rich source of essential amino acids, but its lysine content is lower than optimal. This makes hemp protein a well-rounded option for those seeking a vegan or vegetarian protein source with additional nutritional benefits. However, for individuals specifically focused on maximising muscle-building capabilities, alternative protein sources with higher lysine content may be more suitable.
