Is it safe to use protein powder if you have thyroid disease?

Is animal protein better than plant protein? Which one is ideal if you have thyroid disease?

How much protein should you consume each day? And will it help you with weight loss?

All of these questions are more will be answered in this article. 

But to the point:

Yes, you can and should consume plant-based protein if you have thyroid dysfunction as it can potentially help you manage your weight and help you feel better. 

The specifics are a little bit more complicated so let’s dive in to help you gain a better understanding:

Not All Protein Powders Are Created Equal – What to Look For

One of the main reasons that people want to use protein powder is to help manage their weight. 

You’ve probably been told that working out and using protein powder is a good way to lose weight and build muscle. 

And that CAN be true but let me ask you a question:

Are you using protein powder and is it helping you lose weight?

Do you feel good after you consume your protein powder?

The answer, for most thyroid patients, is a big fat no. 

But why is that?

Much of it has to do with what happens in your body after you consume your protein powder.

If your protein powder isn’t being absorbed, if it’s causing inflammation, if it’s slowing down your thyroid then you won’t see the weight loss you are looking for. 

This is important because if you have thyroid disease then you should be considered in a different ‘group’ when compared to other people. 

Some people (those without thyroid problems) are able to pound down whey protein shakes, lose weight, and feel better. 

But if you are like many thyroid patients then the chances are high that you are not someone who tolerates dairy products or whey protein very well. In fact, whey protein may be doing more harm than good in your intestinal tract and, therefore, your thyroid. 


A big portion of thyroid conversion occurs in the gut. So if you are causing any inflammation or damage to the gut then you may be negatively impacting your thyroid whether you realize it or not. 

And dairy isn’t the only thing you have to worry about if you have a thyroid problem. Many thyroid patients also do not tolerate soy or gluten (1) which are found in some types of protein powders. 

So what is a thyroid patient supposed to do? Avoid protein altogether because it may be harmful to their thyroid gland?

Not by a long shot! 

Fortunately, there are many different types of protein powders that you can use if you have any type of thyroid problem including hypothyroidism, Hashimoto’s thyroiditis, or if you simply don’t have a thyroid

You can get the benefits of protein powder, including weight loss if you use the right type of protein powder! One that doesn’t impede thyroid function or cause gut inflammation. 

As a thyroid patient, you will want to find a protein powder that has the following attributes:

  • Ensure that your protein powder is dairy-free (2), soy-free (3), and gluten-free
  • Make sure that your protein powder contains a broad array of amino acids
  • For extra benefit, look for protein powders that also contain additional vitamins and nutrients that can help support your thyroid
  • Look for protein powders that contain plant-based protein (pea, rice, etc.)
  • You want your protein powder to contain somewhere between 10 grams and 20 grams of protein per serving
  • Make sure that your protein powder does not contain inactive fillers, binders, artificial flavors, GMO products, or dyes

If you follow these recommendations then you can ensure that you are getting what I like to call a “clean” protein powder. 

There are many protein powders out there but if they are causing gut inflammation or other issues then you simply won’t get the effect you are looking for. 

By keeping your protein clean, you can ensure that you absorb all of the protein that you are consuming so it can actually do its job. 

My personal recommendation is to use a protein powder such as this one which fits all of the criteria above. 

I’ve had great success in recommending it to many patients over the years including my own family members. 

If you elect to use a different version, though, just be sure that it meets the criteria listed above! 

5 Big Benefits of Protein Powder & Why Thyroid Patients Should use it

Using the right protein powder on a daily basis can have big benefits for your weight, your thyroid, your metabolism, and more. 

Check out the potential benefits that you can expect to see if you are using protein powder correctly:

#1. May Enhance Weight Loss & Improve Metabolism

If you are like many thyroid patients then you are probably struggling with weight gain. 

Protein powder definitely has the potential to help with weight loss because it impacts your body and metabolism through a variety of different mechanisms. 

One of the most important factors in controlling your weight has to do with your basal metabolic rate or BMR. 

And a huge contributing factor to your BMR is your lean muscle mass. 

The more lean muscle mass that you have on your body, the more calories you will burn at rest. 

Consuming a sufficient amount of protein can help support lean muscle mass which may then have an impact on muscle mass. 

The more muscle mass you have on your body the better, especially if you are struggling with weight. 

If you are trying to lose weight then you should also check out additional weight loss supplements that work through different mechanisms. 

Other supplements including berberine, fish oil, probiotics, CLA, and glucomannan all work through different mechanisms and can be safely used in conjunction with protein powder. 

You can also consider adding other prescription weight loss medications to your protein powder to enhance weight loss. 

#2. Can Help Control Appetite

Another way that protein powder can help with weight loss is through its impact on your appetite. 

It’s no secret that protein, in general, has a powerful impact on appetite control. 

In fact, compared to fat and carbohydrates, protein exerts an even more powerful appetite suppressant-like effect. 

This is great for thyroid patients because it allows them to regulate cravings for sugary foods and sweets while also putting things into their body that tastes great AND may improve thyroid function. 

To get the most benefit, eating a protein smoothie at the beginning of the day can help provide your body with healthy whole foods while also naturally suppressing your appetite throughout the day until lunchtime.

#3. Easy way to get more Nutrients

Using a protein powder every day is an easy way to ‘sneak’ in nutrients that would otherwise be difficult to get. 

What do I mean?

Protein powders often taste very good which means you can hide other not-so-good-tasting supplements or ingredients inside of them. 

Ingredients such as prebiotics, probiotics, iodine, adaptogens, botanicals, and other nutrients can all be placed inside of your protein powder or consumed at the same time.

This is great because it helps to provide you with more of the nutrients that your thyroid needs without sacrificing taste. 

And let’s get real for a second: 

Healthy supplements don’t always taste very good so this is a huge plus. 

You may be able to choke down some unpleasant nutrients for a few days but what happens when it’s day 30 of the same nasty-tasting ingredient? 

Life gets a lot easier when things both taste good AND are healthy. 

#4. Quick and Easy to Prepare

Another big benefit is that you can easily prepare a protein shake with just a few ingredients. 

I know from personal experience that eating healthy can be hard. 

The last thing you want to do when you get home from a long day is to spend 30 minutes cooking a healthy meal. 

You can bypass the cooking process by throwing together a quick protein smoothie. 

Put some water or juice into a blender, throw in 1-2 scoops of protein powder, add some frozen fruit and you have a delicious meal that will help keep you full for hours. 

#5. Tastes Delicious! 

And lastly, another huge benefit is obviously the taste!

Eating healthy food can definitely be tasty, but it requires that you have a working knowledge of how to cook and how to combine flavors, herbs, and spices. 

For some people, this can be difficult and it can make eating healthy not quite as appetizing (or as easy) as simply eating unhealthy food. 

Protein powder can make this transition much easier because it makes creating healthy and good-tasting food much easier. 

Plant-Based Protein vs Animal Protein

If you’re on the protein powder bandwagon then you are probably asking yourself how you can get your hands on some protein powder. 

Well, not so fast because there are a few things we need to discuss. 

The first has to do with the type or SOURCE of protein powder. 

When it comes to protein powder sources, there are two broad categories to choose from:

Animal-based protein powders and plant-based protein powders. 

Plant protein comes from pea, hemp, brown rice, soy, quinoa, amaranth, oats, chia seeds, and even legumes/beans. 

Even though these are all potential sources of plant protein, most plant protein powders contain large amounts of pea, brown rice, and soy protein in various concentrations/ratios.  

On the other side, you also have the option of getting your protein powder from an animal source. 

Animal protein predominately comes in the form of whey (from dairy) but you can also find egg-based protein powders, collagen protein powders, and even hydrolyzed beef protein powders. 

Each of these protein powders has a list of pros and cons that go along with it and for thyroid patients, the cons of animal-based protein powders usually outweigh the pros. 

Even though animal protein powders can work great for many people, thyroid patients often do better with plant-based protein powders for a few reasons:

#1. Most animal-based protein powders come from whey which is a source of dairy. 

And we know that thyroid patients often have a hard time digesting and utilizing dairy products because they can cause intestinal issues and potentially exacerbate immune function (4) in certain people. 

We even have some studies showing that patients with Hashimoto’s thyroiditis who remove dairy from their diet see an improvement in thyroid function in a relatively short time frame. 

And before you think you don’t have to worry about this because you don’t have Hashimoto’s, think again. 

The #1 cause of thyroid disease in the United States and other developed countries is Hashimoto’s thyroiditis so there is a big chance that you have this condition whether you realize it or not. 

#2. Thyroid patients tend to have issues with digestion/absorption of nutrients/foods due to low stomach acid from low thyroid function.

Low thyroid function results in decreased acid production in the stomach. 

This reduction in acid can make it difficult to break down foods into their core components for absorption into the body. 

And because not all protein powders are as easily digestible as others, this is something to consider if you have thyroid problems. 

For most people, plant-based protein powders are more easily absorbed compared to animal protein powders. 

This means that most thyroid patients will have an easier time getting the nutrients and protein from their protein powder into their bodies compared to animal protein powders like whey. 

And #3. Animal protein can sometimes result in bloating, distention, or abdominal cramping.

Remember when I mentioned that plant protein is often better absorbed compared to animal protein?

A lot of this has to do with the concentration of bacteria in your gut known as the microbiome. 

Thyroid patients tend to suffer from overgrowths of certain types of bacteria (and even fungus) which prefer certain types of foods. 

benefits of using protein powder for your thyroid

Food that the bacteria feed off can result in the formation of gas which results in distention, bloating, or cramping. 

Because plant-based protein powders contain different compounds and an array of amino acids, they are utilized differently in the gut. 

In addition, some thyroid patients suffer from food allergies or food sensitivities which can cause similar symptoms. 

In general, dairy and whey tend to cause more issues for thyroid patients compared to plant protein but both can potentially cause problems! 

How Much Protein Should you Consume Daily?

It’s always possible to do too much of a good thing but when it comes to protein, I find that most people are not consuming enough. 

You can find out if you are consuming enough protein in a couple of different ways: 

The first is that you can let your body weight and muscle mass be your guide. 

Your goal, when consuming protein powder, is to find the amount of protein you need to maintain your muscle mass (6). 

This is a little bit complicated because it requires you to have an understanding of the percentage of fat in your body and the percentage of lean muscle mass which means you will need to track it. 

The amount of protein you consume will depend on whether or not you are trying to lose weight, build muscle mass, or maintain muscle mass. 

Because this option is somewhat more difficult to track, you can use a more general rule to guide your protein intake. 

That general rule is to consume 1 gram of protein for each pound that you weigh. 

If you are overweight then you will want to use your target weight as your protein goal as opposed to your current weight. 

Imagine that you are a woman with thyroid problems interested in losing weight. 

Your current weight is 175 pounds but your target weight is 145 pounds. 

In this situation, you would try to consume 1 gram of protein per pound up to 145 pounds. 

So your daily protein goal will be around 145 grams of protein. 

Of this total percentage, around 60% should be from whole foods and around 40% should be from protein powder. 

This is going to seem like a lot of protein for many people, especially women who aren’t used to consuming high quantities of protein but it’s not as difficult as you may think, especially when using protein powder. 

2-4 scoops of protein powder can easily provide your body with up to 40 to 80 grams of protein each day. 

If you are having trouble hitting these levels of protein intake then shoot for something more manageable such as 0.8 grams of protein per pound of body weight (or target body weight, if you are overweight). 

Using the example above, 0.8 grams of protein/pound of body weight gives you a total of 116 grams of protein per day instead of 145. 

This value can be obtained by multiplying your ideal body weight by 0.8. 

Consuming high quantities of protein can really help build muscle mass, suppress your appetite, control your weight, and improve your thyroid. 

Can Protein be Used as a Meal Replacement?

No, no, no, and no. 

Protein powder (by itself) should absolutely not be used as a meal replacement or as a way to reduce your total calories. 

If you use your protein powder in this way you may lose weight temporarily but you will eventually cause metabolic damage which will make weight loss impossible (or VERY difficult) later in your life (8).

The only reason it’s safe to restrict your calories is if you are fasting for a targeted and specific set of times!

Otherwise, as a thyroid patient, you are doing more harm than good to your body when you restrict calories for a prolonged period of time. 

I realize that most people do recommend that you use protein powder as a way to reduce your calories and as a meal replacement but this is not the way that thyroid patients should use protein powder. 

Protein powder is best used as a dietary SUPPLEMENT (9) which can be used to supplement whatever you are currently eating. 


The bulk of your protein should be coming from real WHOLE foods. 

Having said that, it can be difficult to consume enough whole foods to reach your target protein intake, especially if you run a busy life or don’t have time to make meals. 

It should NOT be used by itself as a meal replacement to help you reduce your calories. 

With that in mind, here are two ways that you can use your protein powder for the best results:

Option #1: In a whole food smoothie with at least 20-30 grams of protein (this DOES count as a meal replacement). 

If you want to use your protein powder as a meal replacement then you better combine it with other real whole foods. 

If you throw together a smoothie that contains almond butter, frozen fruit, and vegetables WITH your protein powder then you can safely call this a meal replacement. 

Option #2: As a midday snack to help curb your appetite, achieve your target protein intake, or as a quick meal to keep you from eating unhealthy options.

Option #2 allows some more flexibility but still doesn’t take the place of an entire meal such as breakfast or lunch. 

If you mix your protein powder with some chilled water or non-dairy milk then you can count it as a snack but not a meal replacement. 

Using it in this way can be helpful, especially if you are someone that knows you struggle with midday cravings or if you are struggling to hit your target protein intake through whole foods alone. 

The Best Protein Powder for Thyroid Patients…

Is there a single best protein powder for thyroid patients?

Well, yes, but not in the way that you are thinking. 

The best protein powder will be one that works for YOUR body, one that tastes GOOD, one that you want to use DAILY, and one that provides your body and thyroid with the nutrients that it needs. 

It will probably take you some trial and error to figure out which one works best for you and that’s okay. 

Having said that, there are some basic guidelines that I have learned after helping thousands of thyroid patients over the years. 

If you are just starting out and you don’t know which one to start with then consider these guidelines:

  • Thyroid patients tend to do best on plant-based protein powders, especially protein powders made from pea and brown rice
  • Look for a protein powder that is gluten-free, soy-free, and dairy-free
  • Thyroid patients tend to do WORSE on whey based protein powders due to the dairy component but there are some thyroid patients who can handle whey protein
  • Sometimes pea protein can cause intestinal issues, especially if you have issues such as SIBO or SIFO. In these instances, you may want to consider using something like hydrolyzed beef or hydrolyzed collagen

I’ve spent a lot of time helping thyroid patients over the years and I’ve come up with my own protein powder specifically designed for thyroid patients

It fits all of the criteria above, is well tolerated, and has been tested by thousands of thyroid patients over the last 5 years. 

If you don’t want to use my protein powder then look for one that has similar properties. 


Almost every thyroid patient can stand to benefit from the use of protein powder as a part of their daily supplement regimen. 

Whether you are looking for weight loss, more energy, or a quick and easy snack, protein powder can help you.

My recommendation is that you stick to supplements that contain plant-based protein, which contain additional ingredients, and which do not contain products that can cause negative reactions (gluten, dairy, and soy). 

If your goal is weight loss make sure that you do not use protein powder as a meal replacement! Instead, use it as a snack or as a supplement to a whole-food smoothie in the morning. 

Now I want to hear from you:

Are you currently using protein powder?
