Intro to Protein for ADHD

Food can have a powerful effect on the brain! Did you know that what we eat can positively or negatively impact our cognitive function? 

This blog post will explore the connection between protein and ADHD symptoms, as well as providing ways to incorporate more protein into your life!

What is Protein? 

Protein is one of the three major macronutrients that our body needs to stay healthy (the others being carbohydrates and fat). Macronutrients are the nutrients needed by the body in large amounts in order to provide our body with energy.

Different foods contain some or all of these macronutrients, and each macronutrient plays a different role in our body. In this blog post, we will be focusing specifically on the protein macronutrient.

Every cell in the human body contains protein (1). When looking at the actual structure of proteins, they are made up of chains of amino acids (the individual components that make up protein). This means that when we eat protein, the food is broken down into different amino acids. Once digested, amino acids can combine together to form the protein that our body needs to function (1).

Amino acids

Some roles of protein include:

  • Helps maintain our muscle mass
  • Repairing the body’s tissues (such as for wound healing)
  • Transporting nutrients throughout the body
  • Precursors of hormones and neurotransmitters – this means that they help carry messages around the body to tell it what it can or can’t do (2).

I could talk about the functions of proteins forever but let’s dive into the role of proteins and the brain.

The role of protein for the brain

How does the brain work?

The brain functions like a giant computer. It uses special cells called neurons to carry messages back and forth between the brain and the rest of the body (3). This is how our body knows how to act in different situations. These neurons are able to communicate with each other using neurotransmitters (4).

I briefly mentioned that amino acids (the building block of proteins) function as precursors to neurotransmitters – they tell the neurotransmitters what they can and cannot do. This is vitally important for the brain! 

When we eat protein, it gets digested in our bodies and broken back down into amino acids. In other words, without protein, our body would not be able to carry important messages to our cells or function properly. 

What is the connection between protein and ADHD?

Why do we need protein for ADHD? 


It is believed that a specific neurotransmitter called dopamine is connected to ADHD symptoms (5). Dopamine is responsible for controlling our memory, mood, attention, and movement (6). Individuals with ADHD often produce less dopamine compared to people without ADHD, and as a result may experience poor attention, impulsiveness, distractibility, and hyperactivity (7). 

When you have high levels of dopamine in your brain you feel more alert, motivated, focused, and happy (6)!  It is called the “feel-good” hormone because it gives you a sense of pleasure. 

Providing your body with protein for ADHD may result in higher levels of dopamine, which could possibly help manage ADHD symptoms, such as attention and focus. This is because our body needs amino acids to produce dopamine (eating protein = amino acid production = more dopamine!) (8).

Protein and Blood Sugar 

Did you know that protein can help stabilize blood sugar levels?! When we consume protein, it slows down the digestion of carbohydrates and prevents large spikes in blood sugar levels commonly seen with consumption of refined sugars (10). 

Spikes in blood sugar are often followed by a drop in blood sugar leading to symptoms such as irritability, fatigue, and poor concentration

Extreme fluctuations in blood sugar levels affect our ability to concentrate. Protein can help maintain stable blood sugar levels which can help us maintain energy, focus and concentration throughout the day. This in turn helps manage ADHD symptoms.

Sources of protein for ADHD

  • Eggs 
  • Lean meats and poultry such as turkey and chicken
  • Nuts and seeds
  • Fish and shellfish
  • Beans, peas, and lentils 
  • Dairy products such as milk, yogurt, cheese, and cottage cheese
  • Tofu

How much protein should I eat?

Determining how much protein to eat each day can be overwhelming! Canada’s Food Guide provides a plate method that allows you to visually see if you are eating enough protein. When looking at your plate, ¼ of your meal should come from protein. Click here for more information on the healthy plate method.

A good rule of thumb is to aim to include a protein source in each meal and snack. If you do this you will most likely meet your individual protein requirements!

What happens if you don’t eat enough protein throughout the day?

Since individuals with ADHD already have lower dopamine levels, when they don’t eat enough protein their dopamine levels may become even lower (5). 

Low dopamine levels decrease one’s ability to concentrate (6). Since dopamine is already low in people with ADHD, they often struggle to pay attention as is. With even lower dopamine levels,  concentration can worsen more. 

Protein for ADHD: Spreading out protein throughout the day

It is important to spread your protein intake evenly throughout the day. Remember that point I made about protein helping to stabilize blood sugars? We can focus better when our blood sugar levels are stable

Try following the plate method mentioned above to add some extra protein to your meals and  snacks! 

When we spread out our protein intake throughout our meals and snacks our body is better able to utilize the benefits from dietary protein (11). When we continuously supply our body with protein, we give it more precursors for dopamine!

The Bottom Line 

Overall, protein can have many benefits for ADHD symptoms. Please note that it is NOT a cure for ADHD, but it can help support optimal brain function. 

Protein gives us the building blocks (amino acids) needed to make essential neurotransmitters, like dopamine, to enhance focus and keep our brain happy. It also keeps our blood sugar levels stable, which helps us stay focused and energized.

As long as you include a protein source in each of your meals and snacks you should be consuming enough!
