We’ve talked a lot about Free T3 this week, but if there’s one thing I want you to take away, it’s this: Your Free T3 value needs context.

It’s tempting to look at one number and label it low, normal, or “optimal.” But thyroid physiology doesn’t work in isolation.

Your symptoms, other thyroid markers, medications, nutrition, activity, recovery, inflammation, and overall physiologic state all help us understand what that Free T3 value may actually mean for you.

Don’t just ask, “Is my Free T3 optimal?”
Ask why it’s where it is.
Save this one for the next time you’re looking at your thyroid labs.

Thyroid Thursday- watch now!

If your Free T3 is “low,” does that automatically mean you need to raise it?
Not necessarily.

Free T3 is one piece of the thyroid picture, and I don’t think it makes sense to interpret that number without considering what else is happening in your physiology.
Your symptoms matter. Your other thyroid labs matter. Medications and medication timing matter. Nutrition, energy availability, stress, recovery, inflammation, and your current physiologic state all matter.

That’s why simply trying to push Free T3 into an “optimal” range with more T3 medication may change the number, and may even help someone feel better temporarily, without addressing why that thyroid hormone pattern developed in the first place.

In this week’s Thyroid Thursday, I break down how I look at Free T3 and why the goal shouldn’t just be getting a lab value into someone else’s definition of “optimal.”
The better question is whether that Free T3 value makes sense for YOUR physiology.

EPISODE 245 ⬇️

What is the “optimal” Free T3 level?

You may have heard that your Free T3 needs to be between 4.0 and 4.5 to have optimal thyroid function. And if yours is 2.7, 3.0, or 3.5, you may have been told it’s too low or that you need T3 medication to push it higher.
But where is the evidence that 4.0–4.5 is the right target for everyone?

In this week’s episode of the Thyroid Answers Podcast, I break down what the research actually tells us about Free T3 and why a single number can’t tell us whether your thyroid physiology is working appropriately.

This isn’t an argument against T3 medication. Some people may absolutely benefit from having T3 included in their thyroid hormone replacement.
The problem is when we start chasing a specific Free T3 number without asking why that number is where it is in the first place.

Your medication and timing, nutrition, calorie intake, activity level, recovery, inflammation, metabolic state, and the rest of your thyroid panel all provide context.
A Free T3 of 2.7 isn’t automatically too low.
A Free T3 of 4.4 isn’t automatically optimal.
Instead of asking, “How do I get my Free T3 above 4?”
Maybe the better question is: “Why is my Free T3 where it is, and is that value appropriate for my physiology?”

What is the “optimal” Free T3 range?

Depending on who you ask, you might hear:
→ Between 3 and 4
→ Between 4 and 5
→ Above 5
→ Whatever number makes you “feel better”

But there’s a problem with trying to define one optimal Free T3 range for everyone.
A lab value by itself doesn’t tell us enough.

If your Free T3 is 3.2, for example, that number needs context:
→ Are you taking T3 medication?
→ When did you take it in relation to your blood draw?
→ What do the rest of your thyroid labs look like?
→ What signs and symptoms are you experiencing?
→ What’s happening with your nutrition, activity, recovery, and overall physiology?
Being within the lab reference range doesn’t automatically mean you’re healthy.
And getting your Free T3 into someone’s definition of an “optimal” range doesn’t automatically mean you’ve restored healthy thyroid physiology.
You’ve changed a lab value. Now you have to determine what that change actually means for the person.
Manipulating a lab value ≠ optimizing physiology.
I’m going much deeper into Free T3, “optimal” ranges, and what the research actually shows on tomorrow’s episode of the Thyroid Answers Podcast.

If you’re struggling with thyroid symptoms despite being told your labs are “normal” or “optimal,” it may be time to look at the bigger picture.

Exercise. Fasting. Cold plunges. Supplements. Tracking. Optimizing.

We tend to label these things as “healthy,” but that doesn’t mean your body experiences them the same way in every physiologic state.
Something that helps build resilience when you have the capacity for it may become another source of strain when you don’t.
Instead of only asking, “Is this healthy?” try asking, “Is this helping me recover and become more resilient right now?”
That’s a very different question.

And it’s one of the ideas I explore throughout Is This the Hill?

Hey everybody, back with another Thyroid Thursday.

You may be doing everything “right” during the day.

Exercising. Eating well. Taking your supplements. Working on your health.
But what happens during the last hour before you go to sleep?

If that hour is filled with work emails, social media, news, symptom research, notifications, or anything else keeping your brain and nervous system engaged, you may be missing an important opportunity to support recovery.
The last hour of your day should help shift your body out of activity mode and toward sleep, repair, and recovery.
And that matters for more than just getting a good night’s sleep.
Your nighttime rhythm can influence recovery, metabolism, thyroid hormone conversion, and overall thyroid physiology.

In this week’s Thyroid Thursday, I’m breaking down why protecting the last hour of your day may be one of the simplest changes you can make to better support your physiology.
You don’t need another complicated protocol. Sometimes you need to look at the signals your body is already receiving.

Want to better understand those signals and why they matter?

Your body is constantly receiving information from when you eat and sleep to how you exercise, how much you’re doing, and even what you’re consuming on your phone.

The important question isn’t whether each of those things is “healthy.” It’s what those signals mean in the context of your current physiology. Exercise can help build resilience, or it can become another demand. Fasting may feel great for one person while creating additional strain for someone else. Even scrolling on your phone may feel like downtime while your nervous system is still processing a constant stream of stimulation.

This is why I don’t believe health can be reduced to a list of things you should or shouldn’t do. We need to ask better questions. What signals are you sending your body? Does your body currently have the capacity to respond to those signals the way you want it to? And are the things you’re doing actually helping you become more resilient?

This is a big part of what I explore in Is This the Hill? Understanding why your body responds the way it does can completely change how you approach your health.

Thyroid Answers Episode 245

Could your phone be affecting your sleep, nervous system, and thyroid recovery? 📱
Most people think about nighttime screen use in terms of blue light. But the bigger issue may be everything your phone is delivering to your nervous system.
Work emails. Notifications. Social media. News. Symptom research. Comparison. Conflict. Endless information.

Scrolling may feel like downtime, but that doesn’t necessarily mean your physiology sees it that way.
If you’re struggling with fatigue, poor sleep, waking up tired, anxiety, cravings, or difficulty recovering, it may be worth looking at the signals you’re sending your body in the hours before bed.

→ Are you signaling darkness, predictability, sleep, and recovery?
→ Or are you signaling urgency, stimulation, work, worry, and vigilance?
You don’t need to throw away your phone or create the perfect nighttime routine.
Start with one change.

Stop scrolling in bed. Turn off work email at night. Stop researching symptoms before sleep. Charge your phone outside the bedroom. Give yourself 30–60 minutes to downshift before bed.

Your evening rhythm is either helping you rebuild capacity or borrowing from tomorrow.

In this week’s episode of the Thyroid Answers Podcast, I break down the connection between screen time, sleep, nervous system activation, and thyroid physiology, and why your nighttime routine may matter more than you think.
