Oysters and Essential Amino Acids


Good nutrition is a vital part of maintaining a healthy lifestyle. One of the essential building blocks of good nutrition is protein. Proteins are made up of amino acids, which are crucial components of our body’s chemical structure. Of the 20 amino acids found in proteins, nine are labelled as ‘essential,’ signifying the body cannot produce them on its own. Therefore, we must obtain these essential amino acids (EAAs) through dietary sources.

One particular delicacy that packs a punch when it comes to providing essential amino acids is the delicious oyster. In this blog post, we will explore the world of essential amino acids and why oysters are indeed an extraordinary source of these indispensable nutrients.

What are Essential Amino Acids?

Essential amino acids are critical for maintaining the body’s vital functions. They play a significant role in muscle development, tissue repair, enzyme synthesis, and hormone production. These nine essential amino acids are:

  1. Histidine
  2. Isoleucine
  3. Leucine
  4. Lysine
  5. Methionine
  6. Phenylalanine
  7. Threonine
  8. Tryptophan
  9. Valine

Each of these amino acids serves a specific function in the body, making their dietary consumption a necessary aspect of our well-being. They are found in various food sources, such as meat, dairy, eggs, soy, and some plant-based sources like quinoa, buckwheat, and legumes.

Oysters: A Nutrient Treasure Trove

Oysters, often hailed as a culinary treat, are also incredibly rich in nutritional value. As a potent source of essential amino acids, they provide numerous health benefits, making them an ideal addition to any balanced meal.

  1. Complete Protein Source: Oysters are a complete protein source, which means they contain all nine essential amino acids in sufficient quantities. The term “complete protein” is a prized quality in food as it ensures that the body receives the required nutrients for optimal function.
  2. Low in Calories, High in Protein: Oysters are remarkably low in calories, with only around 68 to 80 calories per 3.5 ounces (100 grams), making them a healthy choice for anyone looking to maintain weight. Despite the low caloric content, oysters boast an impressive amount of protein, roughly containing 7 grams of protein per 3.5 ounces (100 grams).
  3. [Bioavailability]({{< ref “/bioavailability-in-dietary-supplements” >}} “Bioavailability In Dietary Supplemenets”): When it comes to protein sources, not all are created equal – some sources offer more accessible amino acids for the body to absorb and utilize. Oysters have highly bioavailable amino acids, meaning they are more readily absorbed, ensuring the body reaps the maximum nutritional benefits.
  4. Additional Nutritional Benefits: Beyond their EAA profile, oysters are also rich in vitamins and minerals, such as Vitamin B12, zinc, iron, copper, and selenium. Each of these vital micronutrients supports numerous bodily functions like immune health, energy production, and brain function.


In conclusion, oysters are a powerhouse of essential amino acids and provide a complete, bioavailable, and nutritionally dense protein source. Including oysters in your diet will not only satisfy your taste buds but also help maintain a healthy body due to their impressive nutritional profile. So, why not enjoy a plate of delicious oysters and ‘sea’ for yourself how good nutrition can taste!
