Cannabis study shows: Hemp protein is the best plant-based protein

More and more people are discovering plant-based proteins as a sustainable alternative to animal protein sources. But which plant-based protein is really the highest quality? A recent laboratory analysis by HANAFSAN provides clarity: In a direct comparison of various plant-based protein sources, it is shown that hemp protein leads the way in terms of amino acid composition, digestibility, and biological value.

The Scientific Basis: HANAFSAN Analysis of Plant-Based Protein

As part of a study, Dr. Feurstein Medical Hemp GmbH (HANAFSAN) commissioned Quality Services International GmbH (QSI) to conduct a detailed laboratory analysis. Several plant-based protein sources were examined, including hemp protein, pea protein, rice protein, and soy protein. The goal was to compare their amino acid profiles and evaluate their nutritional value. The result is clear: hemp protein has the most balanced and complete amino acid profile of all tested plant proteins.

Detailed Results: Amino Acid Profile of HANAFSAN Hemp Protein

The QSI test reports show that HANAFSAN Organic Hemp Protein (40% protein content) contains all 20 proteinogenic amino acids – including the nine essential ones that the body cannot produce itself.

Amino Acid Content (mg/kg)

Arginine 44,900
Glutamic Acid 72,600
Aspartic Acid 40,400
Leucine 25,000
Valine 19,300
Lysine 17,000
Isoleucine 15,400
Phenylalanine 17,700
Threonine 13,000
Tryptophan 3,600

These values illustrate: hemp protein provides all essential amino acids in an ideal ratio. No other tested plant protein achieved such a harmonious profile.

What Makes Hemp Protein So High-Quality?

The biological value of a protein measures how well the body can convert the ingested protein into its own protein. Hemp protein achieves top values here because it:

contains all essential amino acids,
offers a balanced ratio between them,
and is easily digestible – without known allergens or antinutrients.

Particularly noteworthy are:

Arginine: supports blood circulation and the cardiovascular system.
Leucine, Isoleucine, Valine (BCAAs): promote muscle building and regeneration.
Lysine: often limiting in plant-based diets, but present in ideal amounts in hemp.

Comparison with Other Plant-Based Protein Sources

The HANAFSAN study compared hemp protein with several plant proteins – the result clearly favored cannabis:

Pea protein: Pea protein provides a lot of arginine and lysine but contains little methionine. Therefore, the amino acid balance is unbalanced – hemp protein performs significantly better here.
Rice protein: Rice protein scores with high methionine content but has a deficiency in lysine. Hemp protein compensates for this imbalance and thus offers a more rounded nutrient base.
Soy protein: Soy protein is considered complete but is often genetically modified and potentially allergenic. Hemp protein is free from genetic engineering, hypoallergenic, and at the same time richer in certain amino acids like arginine.
Pumpkin seed and sunflower protein: These proteins contain individual valuable amino acids but are less balanced overall. Hemp protein convinces with its natural balance and high bioavailability of nutrients.

Sustainable, Natural, and Nutrient-Rich

Another plus: hemp is an environmentally friendly crop. It grows quickly, requires little water, no pesticides, and improves soil structure. Thus, hemp protein is not only nutritionally but also ecologically the most sustainable choice among plant-based protein sources. Additionally, hemp protein provides:

fiber for healthy digestion,
omega-3 and omega-6 fatty acids in the ideal 1:3 ratio,
as well as important micronutrients such as iron, magnesium, zinc, and vitamin E.

Practical Application in Everyday Life

HANAFSAN hemp protein powder can be easily integrated into the daily diet:

As a post-workout shake for muscle regeneration, in breakfast (e.g., smoothies, porridge, muesli),
or as a baking ingredient for breads, pancakes,
or energy bars. Thanks to its mild nutty flavor, it is versatile – completely free of artificial additives or sweeteners.

Conclusion: Hemp Protein is the New Standard for Plant-Based Proteins

The HANAFSAN Cannabis study clearly proves: hemp protein delivers the best amino acid profile among plant-based protein sources and can therefore be classified as the best plant protein. It combines highest biological value, natural tolerance, and ecological sustainability – a comprehensively superior protein for health, sports, and the environment.
