Protein Powder for ADHD

Is Protein Powder Good for ADHD?

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects 7.2 percent of children and 3.4 percent of adults around the world.

It is characterized by symptoms such as inattention, hyperactivity, and impulsiveness.

People with ADHD have trouble focusing, completing tasks, and controlling their behavior.

They often act without thinking things through, which can lead to careless mistakes and even dangerous behavior.

The exact causes of ADHD are not yet known, but research suggests that both genetics and environmental factors might play a role (Arch Dis Child, 2011).

Treatment for ADHD typically involves medication, psychotherapy, and behavioral therapy.

Stimulant medications, such as Ritalin and Adderall, are commonly used to help manage symptoms like inattention and hyperactivity.

Medication aside, ADHD can affect appetite in several ways.

For example, people with ADHD may not notice when they are hungry because they are distracted or hyper-focused on other tasks.

This can lead to irregular eating patterns, such as skipping meals or forgetting to eat altogether.

ADHD medications, particularly stimulant medications like Adderall and Ritalin, can also affect appetite.

Many individuals taking ADHD medications report feeling less hungry, especially during the day when the medication is most active.

This too can lead to meal skipping, particularly in the morning.

It can also cause binge eating later in the day when appetite returns.

The effects of ADHD and ADHD medications on appetite can sometimes lead to weight loss and malnutrition, which is a particular concern for growing children.

On the other hand, sudden cravings and overeating later in the day can lead to unhealthy weight gain.

For someone struggling with irregular eating, a protein supplement can be hugely helpful.

On the one hand, the convenience and versatility of protein supplements can help those who struggle with low appetite as having easy access to a liquid meal makes meeting nutritional needs easy.

On the other hand, eating lots of protein, which is the most filling macronutrient, can curb carvings and overeating.

Not all protein powders are created equal, however, and some might not be safe for someone with ADHD.

What Is the Best Protein Powder for ADHD?

Unless you have a food allergy or sensitivity, type or amount of protein is not what you have to worry about.

Instead, it is added ingredients that tend to be problematic.

Among top offenders are food additives.

🚫 Avoid Food Additives

Regularly eating emulsifiers, thickeners and other additives can not only upset your stomach, but also alter the composition of your gut microbiome (North Clin Istanb, 2019).

Over time, this can lead to gut dysbiosis (Microorganisms, 2022), which has been linked to the development of neuropsychiatric conditions like ADHD (Nutrients, 2021).

Keep in mind that your gut microbiome influences your mental health via the gut-brain axis, a two-way communication pathway connecting your gut and brain.

⚠️ Here is a list of the most common food additives in protein supplements:

• acacia fiber
• acacia gum
• acesulfame potassium
• artificial flavors
• ascorbic acid
• aspartame
• calcium carbonate
• carrageenan
• cellulose gum
• dextrin
• dicalcium phosphate
• dipotassium phosphate
• erythritol
• gellan gum
• guar gum
• gum arabic
• inulin
• locust bean gum
• maltitol
• maltodextrin
• mono- and diglycerides
• ‘natural’ flavors
• rice bran extract
• rice dextrin
• rice hulls
• rosemary extract
• silica
• silicon dioxide
• sodium alginate
• soluble corn fiber
• sorbitol
• soy lecithin
• sucralose
• sunflower lecithin
• tocopherols
• tricalcium phosphate
• xanthan gum
• xylitol
• zinc oxide

As a rule of thumb, if you cannot find it in nature or make it at home, it is probably a food additive.

🚫 Avoid Dairy-Based Proteins

Dairy-based proteins like whey and casein, although not an issue for everyone, can cause digestive issues too.

This is usually because they contain lactose, a sugar many individuals with sensitive stomachs cannot fully digest.

But you might be sensitive to dairy-based proteins even if you are not lactose intolerant.

This is particularly true for casein protein, which forms a gel-like substance in your stomach that slows down digestion.

🚫 Avoid Protein Concentrates and Isolates

You might also want to avoid ultra-processed protein concentrates and isolates.

Most protein supplements are made from one or both of these ultra-processed protein sources, which have been mechanically and/or chemically stripped of everything but the protein.

This includes the enzymes, fiber, and other natural digestive aids that help your gut break them down.

You therefore do not digest them in the same way that you do whole foods, which could affect your gut health.

Studies show that regularly eating protein concentrates and isolates might disrupt your gut microbiome and cause the formation of toxic byproducts in your gut ((Nutrients, 2018; Mol Nutr Food Res, 2024).

You should thus look for protein supplements made from whole food protein sources like egg whites and almonds, which are easier to digest and absorb.
