30 Foods High In Arginine (2024)

Arginine is an amino acid that plays a range of important functions in the body.

This article provides a list of foods high in arginine alongside an overview of why arginine is important.

Before we explore the richest dietary sources, let’s first take a look at what arginine is.

What Is Arginine?

30 Foods High In Arginine (1)

Arginine, also known as L-arginine, is an amino acid used by the body to make protein.

Some amino acids are deemed essential, meaning that the body cannot produce them and requires them from the diet.

Conversely, certain amino acids are considered ‘non-essential’ since the body can produce them internally.

In the case of arginine, this amino acid has the distinctive class of a ‘conditionally essential’ amino acid (1, 2).

Although the body can produce it, there are specific circumstances in which the body may require additional arginine from the diet.

This is because, at times, the body’s arginine requirements may be higher than the amount it can produce. Some instances where we may require extra arginine include (3, 4):

  • Injury, illness, and certain diseases: The body uses arginine for recovery and wound healing. Specific conditions may increase arginine requirements or lower the body’s endogenous (internal) production of it.
  • Growth: Arginine plays a key role in the growth and development of children and teenagers.
  • During pregnancy: Arginine requirements increase during pregnancy to help the growth of the developing baby.
  • After exercise: Arginine needs are higher when following a heavy exercise program. Arginine plays a role in performance and recovery as it is a precursor to nitric oxide, which is involved in blood flow regulation.

How Can We Get Enough Arginine?

Most individuals typically consume a sufficient amount of arginine from their daily diet.

Given that most protein-rich foods have a high arginine content, maintaining a sufficient protein intake throughout the day should ensure a sufficient arginine intake.

Foods such as meat, seafood, legumes, and nuts all tend to be high in arginine.

Key Point: Arginine is a conditionally essential amino acid, and most people consume it in sufficient quantities from their daily diet.

Is Arginine Supplementation Beneficial?

In addition to arginine-rich foods, it is possible to purchase arginine supplements.

Firstly, as mentioned earlier, the majority of individuals obtain sufficient arginine from their daily diet and are unlikely to significantly benefit from supplementation.

That said, arginine supplementation may have potential benefits for certain individuals.

For example, arginine is a precursor for nitric oxide, so higher intakes may enhance nitric oxide production (35). Nitric oxide helps to dilate blood vessels, thus improving blood flow, which could potentially improve performance for intense exercise and physical activities.

Some studies show potential performance benefits from arginine supplementation, but the data is inconsistent, showing mixed results (36, 37).

Furthermore, research has also demonstrated that arginine supplementation might be effective for lowering blood pressure (38, 39).

However, as Mayo Clinic states, “because they can affect how some medicines work and worsen certain health conditions, they (arginine supplements) shouldn’t be taken unless a healthcare professional recommends them” (38).

Anyone considering arginine supplementation should discuss the matter with their primary healthcare provider beforehand.

Final Thoughts

Arginine is an important amino acid that is conditionally essential for human health.

However, the majority of people obtain sufficient amounts of arginine from their daily diet.

Arginine can be found in high concentrations in most animal-based proteins as well as protein-rich legumes, nuts, grains, and seeds.
