Seitan, often pronounced as ‘say-tan,’ is a vegan meat substitute made entirely from hydrated wheat gluten. Known by various names like wheat meat, vital wheat gluten, wheat protein, or simply gluten, seitan has gained popularity in both vegan and omnivore diets due to its low-carb, low-fat, and high-protein composition. In this article, we will explore seitan’s amino acid profile and answer the crucial question: Is seitan a complete protein? And if not, how can it be made into one?

Understanding Amino Acids
Before delving into seitan’s protein content, it’s essential to understand the role of amino acids in nutrition. Amino acids are the building blocks of proteins and come in two categories: essential and non-essential.
- Essential Amino Acids: These amino acids are not naturally produced by our bodies and must be obtained from our diet or supplements. They play a crucial role in building and repairing muscle tissues and are essential for overall health.
- Non-Essential Amino Acids: Unlike essential amino acids, our bodies can synthesize non-essential amino acids. They are involved in various functions, including toxin removal, red and white blood cell synthesis, and brain function support.
What Makes a Protein Complete?
A protein is considered complete when it contains all nine essential amino acids required by the human body. These nine essential amino acids are histidine, lysine, methionine, threonine, tryptophan, phenylalanine, isoleucine, leucine, and valine. These amino acids cannot be synthesized by the body and must be obtained from dietary sources.
Seitan’s Amino Acid Profile
Seitan is often hailed as a high-protein vegan superfood, but it falls short of being a complete protein. It contains eight essential amino acids but lacks lysine. However, this deficiency can be easily addressed by adding a source of lysine to your meal. One convenient option is to incorporate a vegan branched-chain amino acid (BCAA) supplement into your diet, ensuring you cover your lysine needs.
Here is the amino acid profile of seitan, comparing the minimum percentage required in a complete protein source to the amount present in seitan:
- Isoleucine: 3% (Seitan: 4.1%)
- Histidine: 1.5% (Seitan: 1.7%)
- Leucine: 5.9% (Seitan: 7.2%)
- Methionine + Cysteine: 1.6% (Seitan: 3.5%)
- Lysine: 4.5% (Seitan: 1.4%)
- Phenylalanine + Tyrosine: 3% (Seitan: 7.2%)
- Threonine: 2.3% (Seitan: 2.8%)
- Valine: 3.9% (Seitan: 5.4%)
Despite lacking lysine, seitan is an excellent source of protein, providing 21 grams of protein per one-ounce serving of vital wheat gluten, along with 104 calories. It is low in carbohydrates (4 grams) and fat (0.5 grams) per serving, making it a favorable choice for those seeking a protein-rich, low-calorie option.
Enhancing Seitan’s Protein Profile
To transform seitan into a complete protein, you can adjust its recipe by adding an extra ingredient like chickpea flour or nutritional yeast. This addition helps balance the lower lysine concentration and ensures you obtain all essential amino acids in your meal.
Sources of Lysine
If you’re looking to supplement your diet with lysine, there are various vegan sources rich in this essential amino acid. Consider adding the following foods to your diet to complement seitan:
- Potatoes, leeks, and peppers
- Quinoa, amaranth, and buckwheat
- Avocado, pears, and dried apricots
- Soy, chickpeas, and kidney beans
- Macadamia nuts, cashews, and pumpkin seeds
By combining these lysine-rich foods with seitan, you can create complete protein meals that meet your nutritional needs.
A Word of Caution
While seitan offers a nutritious source of protein, it’s important to note that it is a highly processed food. If your diet relies heavily on processed foods, consider incorporating whole foods to ensure a balanced nutritional intake. Additionally, store-bought seitan products may contain higher sodium levels, so it’s advisable to monitor your sodium intake.
Important: Avoid consuming seitan if you have allergies, sensitivities, or intolerances to wheat or gluten protein. Individuals diagnosed with Celiac disease, gut problems, or who are under specific medications that restrict gluten or sodium intake should also refrain from consuming seitan.
In conclusion, seitan is a valuable protein source for vegans and individuals looking to reduce their meat consumption. While it falls short of being a complete protein due to its low lysine content, simple recipe adjustments or the addition of lysine-rich foods can easily remedy this. For a diverse and balanced vegan diet, explore the rich variety of plant-based protein sources available.
