Thyroid Answers Podcast

How many supplements are sitting in your cabinet right now? Five? Ten? Twenty or more? And more importantly, do you know why you're taking each one?
In this episode of the Thyroid Answers Podcast, Dr. Eric explores why taking more supplements doesn't always translate into better health. Many people continue to struggle with fatigue, bloating, constipation, poor sleep, hair loss, and other persistent symptoms despite taking an ever-growing list of supplements.
The problem may not be that you need another supplement. It may be that your current strategy needs a closer look.
Dr. Eric explains why every supplement should have a clear purpose, how adding too many products at once can make it difficult to identify what's actually helping, and why chasing better lab numbers doesn't always mean you're improving your health. He also discusses how inappropriate doses, overlapping ingredients, and side effects from one supplement can lead to a cascade of additional interventions.
You'll learn how to evaluate your current supplement routine, why a more targeted approach can be beneficial, and what to consider when persistent symptoms and multiple deficiencies suggest there may be a deeper issue to address.
In this episode, you'll learn:
Why a growing supplement routine doesn't necessarily mean you're getting healthier.

How to determine whether each supplement is still serving a purpose.

Why introducing supplements one at a time can provide more useful information.

How taking too much, too quickly can contribute to unwanted symptoms.

Why improving a lab value doesn't automatically mean you're feeling or functioning better.

How one supplement's side effects can lead to an unnecessary cycle of additional products.

How to approach simplifying a supplement routine and evaluating what is actually helping.

Why nutrition, digestive capacity, and chronic stress deserve attention when deficiencies and symptoms persist.

How to recognize when your supplement protocol may have become more of a burden than a benefit.

The bigger takeaway: The goal isn't to take the most supplements possible. It's to understand what's driving your symptoms, use interventions with a clear purpose, and continually evaluate whether your approach is helping you recover.

Ferritin is one of the most confusing laboratory markers in functional and integrative medicine.
A ferritin of 35 might be called iron deficiency by one practitioner, completely normal by another, and "far too low" by someone else who wants it between 70 and 100.
So which is it?
In this episode of the Thyroid Answers Podcast, Dr. Eric Balcavage breaks down what ferritin actually tells us, why serum ferritin is not the same thing as stored iron, and why a ferritin number cannot be interpreted in isolation.
He explains how ferritin fits into the larger picture of iron physiology, including serum iron, transferrin saturation, TIBC, CBC markers, soluble transferrin receptor, reticulocyte hemoglobin, and inflammatory markers.
More importantly, he challenges the idea that there is one universally optimal ferritin range everyone should reach. A ferritin of 35 does not automatically mean iron deficiency, just as a ferritin of 70 or 100 does not automatically mean better health.
The goal is not to optimize ferritin. The goal is to understand the physiology behind the number.
In This Episode, We Cover:
What ferritin actually is and how it stores iron inside cells

The difference between intracellular ferritin and serum ferritin

Why serum ferritin is an indirect marker rather than a direct measurement of stored iron

Why a ferritin of 35 can mean very different things depending on the rest of the iron panel and the person's physiology

Why ferritin increasing after iron supplementation does not prove that someone was iron deficient

How inflammation and hepcidin can affect iron transport and availability

The difference between true iron deficiency and inflammatory iron restriction

Whether there is actually evidence for a universal "optimal" ferritin range of 70 to 100

Why higher ferritin does not automatically mean healthier iron physiology

How ferritin can be interpreted alongside CBC, serum iron, transferrin saturation, TIBC, soluble transferrin receptor, reticulocyte hemoglobin, and inflammatory markers

Why the cause of iron deficiency matters just as much as replacing the iron

Common causes of iron deficiency, including blood loss, inadequate intake, increased demand, and impaired absorption

Why continually increasing iron can create problems when iron deficiency is not the actual issue

What elevated ferritin may tell us about inflammation, iron loading, liver stress, metabolic dysfunction, infection, or cellular stress

Why "appropriate" may be a better question than "optimal" when interpreting ferritin

The Bigger Picture
A laboratory value is not always the problem. Sometimes it is telling us a story about the person's physiology.
Ferritin is no different.
A ferritin of 35 does not automatically mean you need to take iron until you reach 70. A ferritin of 50 does not automatically need to become 80. And a ferritin of 100 does not automatically mean your iron physiology is healthier.
The better question is whether the ferritin makes sense in the context of the entire picture.
Before chasing a number, understand the physiology.

Get Dr. Eric's Book
If you haven't picked up a copy of Is This the Hill?, it is available in hardcover, paperback, and Kindle.
The premise of the book is simple: learn how to recognize when you're spending your time, energy, money, and emotion fighting the wrong battle.
Because chasing ferritin simply because someone told you it needs to be higher can absolutely become one of those hills.

You can feel terrible, have significant symptoms, and still be told your lab work is normal. So you start looking for optimal ranges instead. But is replacing "normal" with "optimal" really helping us understand what's happening?
In this episode, Dr. Eric Balcavage explains why laboratory values need to be interpreted in the context of symptoms, other lab findings, metabolic demand, and overall physiologic state. A number can be normal but inappropriate, or abnormal but appropriate for the state someone is in.
The goal isn't to chase a number. It's to understand what the number is telling us and why.
In this episode, you'll learn:
What laboratory reference ranges actually tell us and what they don't

Why "optimal" ranges don't always explain persistent symptoms

The four ways to interpret a laboratory value: normal and appropriate, normal and inappropriate, abnormal and appropriate, or abnormal and inappropriate

Why a low Free T3 doesn't automatically mean you need T3 medication

How nutrition, sleep, stress, inflammation, activity, and recovery influence laboratory patterns

Why lab values may be signals of an underlying physiologic state rather than the problem itself

Why more testing and treating individual numbers don't always lead to better outcomes

Your lab results aren't a scorecard. They're information. The key is understanding what they mean for you and what needs attention first.
If you've been told your labs are "normal" but you still don't feel well, or you've spent years trying to optimize every number without understanding why those numbers are changing, this is exactly the kind of problem I work through with my clients.

What if the reason you keep getting stuck in thyroid care isn't that you haven't found the right treatment yet?
What if you've simply been given another number to chase?
You started this process because you didn't feel well. Maybe you were tired, gaining weight, cold, dealing with brain fog, constipation, hair loss, or simply didn't feel like yourself.
But somewhere along the way, the focus can shift from why you don't feel well to which laboratory value isn't where someone thinks it should be.
First it's TSH.
Then maybe it's Free T3 or reverse T3.
Then ferritin, vitamin D, estrogen, progesterone, cortisol, or whatever the next round of testing happens to show.
The message remains essentially the same: This value isn't optimal yet. If we can get it into the right range, you should feel better.
But optimizing a laboratory value, optimizing thyroid physiology, and actually improving your health are not automatically the same thing.
In this episode, I explain why the pursuit of optimization can become another hill to climb, and why the more important question may not be "How do I get this number into the optimal range?"
It may be:
"Why does this number look this way in the first place?"
In this episode, I cover:
Why getting your TSH into a preferred range doesn't necessarily mean you've restored your health
The difference between optimizing a laboratory value and actually improving physiology
Why both conventional and functional approaches can fall into the same optimization trap
How Free T3 and reverse T3 can become the next numbers to chase after TSH has been "optimized"
Why changing a lab value doesn't automatically mean you've addressed the reason it was abnormal
How repeatedly searching for the next abnormal lab can keep you stuck in an endless cycle of testing and treatment
Why lab values may sometimes reflect an adaptation to the physiologic state you're in
How energy availability, sleep, stress, exercise, inflammation, and overall load can influence thyroid physiology
Why a low Free T3 may need to be interpreted in the context of the person's current state
The potential consequences of trying to force thyroid values into a preferred range
Why improving sleep, recovery, capacity, and resilience may matter more than hitting a specific laboratory target
How to start viewing laboratory values as information about your physiology rather than simply targets that need to be manipulated
The Problem With "Optimal"
If you finally get your TSH where someone wants it and you still feel exhausted, you may be told that TSH wasn't the important number after all.
Then Free T3 becomes the target.
Maybe reverse T3 becomes the target.
Then perhaps ferritin, vitamin D, sex hormones, cortisol, insulin, or something else becomes the next target.
The numbers change, and the treatment strategy changes, but the underlying assumption can remain exactly the same:
If we can manipulate the laboratory value into the right range, your health should follow.
But what happens when the number changes and you still don't feel well?
That's when we have to start questioning the model itself.
Stop Chasing the Number. Start Asking Why.
When you see an abnormal laboratory value, it's extremely tempting to assume that the number is the problem.
But a better question is:
Why does my physiology need to maintain this pattern?
What is keeping you in the state that's producing that laboratory value?
What is happening with your sleep, nutrition, exercise, stress load, habits, inflammation, and overall capacity?
And could the thyroid pattern you're seeing be an adaptation to the conditions your body is currently trying to operate under?
This is where state-based medicine changes the way we think about the word optimal.
Before deciding that a number needs to be pushed higher or lower, we need to understand why the body produced that number in the first place.
A Low Free T3 Doesn't Tell the Whole Story
Consider two very different people.
One person is sleeping well, eating enough, recovering from exercise, managing stress reasonably well, and functioning in a resilient state.
Another person is undereating, exercising heavily, getting five or six hours of sleep, dealing with significant life stress, and struggling to recover.
Their Free T3 values cannot simply be interpreted the same way without considering the state they're in.
Research discussed in this episode shows that reduced energy availability can be associated with lower total and Free T3 and increased reverse T3 in exercising women.
That doesn't mean every low Free T3 is an adaptive response, or that abnormal thyroid patterns should simply be ignored.
It means the laboratory value needs to be interpreted in context.
A number on a piece of paper doesn't tell you why it looks the way it does.
The Goal Isn't a Perfect Lab Panel
The goal was never a TSH of 1.3.
It was never a Free T3 of 4.
It was never a reverse T3 of 9, ferritin of 80, or vitamin D of 70.
Those are numbers.
The goal is to restore health, improve capacity, become more resilient, and get your life back.
Sometimes improving the conditions driving the adaptation can allow thyroid physiology to improve without simply forcing the laboratory value higher with medication or supplements.
And when the laboratory values improve along with signs, symptoms, recovery, and overall health, the numbers become evidence that the physiology is improving rather than the sole definition of success.
Ask a Different Question
Instead of continually asking:
"What do I need to do to optimize this number?"
Start asking:
"Why does this number look this way?"
"What state is my body in?"
"How much load am I carrying?"
"How much capacity do I actually have?"
"What needs to change so my physiology no longer needs to maintain this pattern?"
That shift can change the entire way you approach thyroid recovery.
The lab value stops being the hill you're fighting.
It becomes information that helps you figure out which hill actually matters.

You can be doing everything you've been told is "healthy" and still feel like you're getting worse.
You cut calories. You cut carbohydrates. You exercise more. You add strength training, cardio, sauna, cold exposure, supplements, and more.
Then you look at your labs and see that your free T3 is low, so you add thyroid medication to try to bring that number up.
At some point, getting healthy can become a full-time job.
The problem is that more effort does not automatically produce more recovery. Sometimes, more effort becomes part of the load.
In this episode, I explain why the same strategy that helps one person can create a bigger mismatch for someone else, depending on their current physiologic state and available capacity.
In this episode, I cover:
Why doing "everything right" can still leave you feeling worse

The difference between a healthy stressor and a stressor your body can actually recover from

Why exercise, fasting, calorie restriction, sauna, cold exposure, and other interventions all require physiological resources

How energy availability can influence thyroid physiology, including T3 and reverse T3

Why a low free T3 should be interpreted in the context of the person, rather than treated as an isolated problem

How treating every abnormal lab value as another problem to fix can turn your recovery plan into another source of stress

Why raising a thyroid marker does not automatically mean you improved the underlying physiology

The potential trade-offs that can happen when you change one part of physiology

What to look at beyond the number you are trying to optimize

Why increased capacity, better recovery, and a more functional life are better measures of progress than simply having more "optimal" numbers

How to determine which health battles actually deserve your attention right now

The Bigger Question
The question isn't simply whether exercise, fasting, supplements, thyroid medication, or another intervention is "good" or "bad."
The better question is:
Can your body currently absorb this demand, recover from it, and become more capable because of it?
When capacity is high, you may be able to tolerate a significant amount of stress.
When you're in chronic strain, you have less room to absorb additional demands.
And when you're in overload, you may be spending resources faster than you can restore them.
That distinction matters because sometimes the thyroid pattern you're trying so hard to fix isn't actually the hill.
It may be the clue pointing you toward the hill you should actually be looking at.
What Does Recovery Actually Look Like?
Recovery shouldn't require your entire life to revolve around managing your health.
Instead, look at whether your overall capacity is improving.
Are you:
Sleeping better?

Recovering better?

Experiencing more stable energy?

Tolerating exercise better?

Able to handle a demanding day without paying for it for the next three days?

Able to travel without your physiology falling apart?

Able to occasionally go out to dinner or miss a workout without feeling like you've destroyed your progress?

Requiring fewer interventions instead of more?

Living a bigger life?

Those are signs that capacity is increasing.
The goal isn't to become better at fighting every possible health battle.
The goal is to understand your state, understand the load you're carrying, figure out what actually matters right now, and put your resources toward the things most likely to increase your capacity.
Sometimes that means doing more.
Sometimes it means doing things differently.
And sometimes it means having the discipline to stop doing something you were convinced was helping.
