“My labs were always "in range" but I still felt awful. I'd tried iron, vitamin D, all of it. Turns out my T4 wasn't converting into the active T3 my body could actually use. This is the first thing that held. I just wish I'd found it sooner.”

Frequently asked questions
Can I take it with my thyroid medication?
Yes, that's what it's for. Your pill delivers the hormone, and Conversion Complex helps your body use it. It works alongside levothyroxine, Synthroid, Armour, Tirosint, NP Thyroid and Unithroid, and it doesn't replace any of them.
Take your thyroid pill on an empty stomach as usual, then two capsules with your first meal, at least an hour later.
What does it actually do?
Your liver is where up to 80% of your T4 converts into the active T3 your body actually uses. Years of thyroid inflammation can slow that liver down, and the conversion slows with it.
Conversion Complex works in three steps.
Wake. Milk thistle, dandelion and artichoke wake the liver and clear the pathway.
Repair. Choline clears the fat quietly congesting the liver, and glutathione repairs what years of inflammation wore down.
Convert. Selenium, the mineral that finishes the job and turns T4 into active T3.
Most thyroid supplements start at the last step and wonder why nothing happens.
How does fixing my liver help my heart?
Because your liver has two quiet jobs, and they fail together.
The first is activating your thyroid hormone. The second is pulling cholesterol out of your blood before it builds up in your arteries.
Years of thyroid inflammation slow that liver down, so both jobs stall at the same time. That's why your energy crashed and your cholesterol climbed: one overlooked organ, two problems, and nobody connected them for you.
Support the liver, and it goes back to doing both.
How long until I feel results?
Most women notice something in the first week, usually sleep, and less of that wired-but-exhausted feeling by mid-afternoon. Brain fog and energy tend to shift around weeks 3 to 4.
Metabolism, weight, hair and skin come later, usually weeks 6 to 8, with the full benefit by 90 days. Every woman is different, and the guarantee covers the whole 90 days.
I had my thyroid removed. Does it apply?
Yes. Your levothyroxine still has to be converted into T3, and up to 80% of that happens in your liver, so the step Conversion Complex supports is the same.
Is it safe with Hashimoto's?
Yes. It was built for women with Hashimoto's and other thyroid conditions.
There's no iodine in it, which matters because iodine can flare Hashimoto's and many thyroid supplements load up on it. Every ingredient in Conversion Complex was chosen for the conversion step in your liver.
What if it doesn't work for me?
Then you don't pay. Every order has a 90-day money-back guarantee.
Email us, send back whatever's left (empty bottles are fine) and we refund you in full. We'd rather earn your next order than keep this one.

I actually wake up feeling rested

Why your labs say in range
A routine thyroid check, and what it leaves out
TSH
In range
Free T4
In range
Free T3
Rarely checked
How much T4 becomes T3
Not on the report
That's how you can be in range and still feel this way.
Your TSH reads normal because the tank is full. Levothyroxine keeps it topped up with T4, but a full tank doesn't take you anywhere until your liver turns that fuel into T3, the form your cells actually burn. When that step slows down, the tank stays full, your labs stay in range, and you still run on empty.
Conversion Complex supports your liver at exactly that step, so the T4 you already have can do its job.
What you've already tried
You tried everything. Here's why none of it held.
You were doing everything almost right. One step was always missing. Tap the ones you've tried.
Tap any you've tried to see why it didn't hold.
More of the storage form
A higher levothyroxine dose
A bigger dose raises the T4 on your report. If the step that turns T4 into T3 is slow, more T4 doesn't become more of the hormone you feel, which is how the numbers get fixed while you feel the same. Keep taking it as prescribed. It just can't do the second half on its own.
The last step, taken first
Selenium on its own
Selenium finishes the conversion. Taken alone, into a liver that's still congested, it arrives at a step that hasn't started yet. That's why so many women take it for months, feel no different and never find out why.
Aimed at the gland
Thyroid support blends
Most of them work on the thyroid itself, and many add iodine or kelp. The conversion happens mostly in your liver, and they leave it out. If one did nothing for you, that's usually why.
The right herbs, at a sip's dose
Liver teas
Milk thistle and dandelion are in a lot of liver teas, but a cup carries only a trace of each, with nothing for the repair step and no selenium to finish the conversion. All three steps have to happen, in order, at a dose that does something.
A push in the wrong place
Iodine or kelp
Iodine helps make thyroid hormone, not convert it, and many women with Hashimoto's feel worse on it. That's why there is none in Conversion Complex.
Real effort, a different step
Gluten-free, AIP or clean eating
It takes real discipline, and it helps some women. If you gave up foods you love for years and still felt the same, that's because cutting foods out doesn't reach the step where your liver turns T4 into T3.
Worth fixing, a different job
B12, iron or vitamin D
If you're low, they're worth fixing. But you can fix every one of those numbers and still feel no different, because none of them clear the liver pathway the conversion runs through.
In range, so nobody looked further
Being told it's age or stress
Your labs said in range, so the conversation stopped there, and you started to wonder if it was you. Routine tests look at the storage form. They rarely show how much of it your body actually uses.
The step they all missed
Your liver turns the T4 from your thyroid and your pill into T3, the form your body runs on. When it slows down, nothing above it can make up the difference. That's the step Conversion Complex supports.
Your pill does half the job. Your liver does the rest.
Levothyroxine gives you T4, the storage form. Your cells run on T3. Up to 80% of that conversion happens in your liver.
Tap to see the difference
Your thyroid and your pill make T4
The storage form. On its own it can't power a single cell.

Conversion running
Your liver converts it to T3
Years of thyroid inflammation slow this step down, and T4 backs up here.

T3
T3 switches your body back on
Too little arrives. You feel it as tiredness, fog, the cold and a weight that won't move.
Energy, warmth, metabolism and a clearer head.
Your pill is doing its half. The step after it has slowed, which is why your labs can still say in range.This is the step Conversion Complex supports: wake, repair, convert.

The formula, in order
Three steps, in the order your liver needs them
You have to clear the road before you can drive on it. Most thyroid supplements start at the last step, which is why selenium on its own so often does nothing.
Step 1WakeMilk thistle, dandelion, artichoke
Milk thistle 250 mg, dandelion 100 mg, artichoke 100 mg, all cold-processed. These wake the liver and get bile moving again, so the pathway your T4 travels through is clear.
Step 2RepairCholine, glutathione
Choline 50 mg, glutathione 25 mg. Choline clears the fat quietly congesting the liver. Glutathione repairs what years of inflammation wore down.
Step 3ConvertSelenium
Selenium 50 mcg, as L-selenomethionine, 91% DV. The mineral your conversion enzymes are built from. It finishes the job and turns T4 into active T3. We use the organic form your body absorbs well.
All three steps happen inside the same two capsules with your first meal, so your routine never changes.
Your daily routine
Keep your levothyroxine. Add two capsules.
Your levothyroxine stays exactly as it is. Conversion Complex finishes the job it starts, in your liver.
Step 1
Your thyroid pill, as prescribed
Take your levothyroxine first thing, on an empty stomach, exactly as your doctor told you. Same pill, same dose.
Step 2
Two capsules with your first meal
Two capsules with breakfast, kept an hour clear of your thyroid pill, the same way your coffee already is. That's the whole routine, and one bottle lasts a month.
Step 3
Then watch for the small things
Most women notice something in the first week: easier sleep, a lighter afternoon, warmer hands. The rest builds over 90 days.
Works alongside levothyroxine, Synthroid, Armour, Tirosint, NP Thyroid and Unithroid. There is no iodine in it and no hormone. On a blood pressure pill or a statin too? Show your pharmacist the label.

How to tell it's working
This week, write down how you slept and how you felt at 3pm. That's your before.
Weigh yourself every Sunday morning, on the same scale, and take your resting pulse before bed.
If you have bloodwork around day 60, ask your doctor to include cholesterol, and free T3 if they'll run it.

5 reasons women choose Conversion Complex
What makes it different from the thyroid aisle you've already tried.
Reason 1
It starts where your pill stops
Levothyroxine gives you T4. This supports the liver step that turns it into T3, the step your prescription never touches.
Reason 2
The right order
Selenium finishes the conversion, but it needs a clear pathway to work on, so the formula clears the liver first.
Reason 3
Nothing that fights your prescription
It works alongside your levothyroxine and has no hormone in it. Two capsules with breakfast, an hour after your pill.
Reason 4
Every dose on the label
Six ingredients at the doses we list, third-party tested, with no proprietary blend. Easy to show your doctor.
Reason 5
90 days to decide
Give it the full course. If it's not for you, email us and we refund you in full.
Questions women ask us
Can I take it with my thyroid medication?
Yes, that's what it's for. Your pill delivers the hormone, and Conversion Complex helps your body use it. It works alongside levothyroxine, Synthroid, Armour, Tirosint, NP Thyroid and Unithroid, and it doesn't replace any of them.
Take your thyroid pill on an empty stomach as usual, then two capsules with your first meal, at least an hour later.
Morning or night?
With your first meal. That keeps the capsules an hour clear of your thyroid pill, the same way your coffee already is, and breakfast is the easiest routine to keep every day.
How does fixing my liver help my heart?
Because your liver has two quiet jobs, and they fail together.
The first is activating your thyroid hormone. The second is pulling cholesterol out of your blood before it builds up in your arteries.
Years of thyroid inflammation slow that liver down, so both jobs stall at the same time. That's why your energy crashed and your cholesterol climbed: one overlooked organ, two problems, and nobody connected them for you.
Support the liver, and it goes back to doing both.
Do I need to change what I eat?
No. Eat the way you normally do and take the capsules with your first meal. If your doctor has you off gluten for celiac disease, keep to that.
Is it safe with Hashimoto's?
Yes. It was built for women with Hashimoto's and other thyroid conditions.
There's no iodine in it, which matters because iodine can flare Hashimoto's and many thyroid supplements load up on it. Every ingredient in Conversion Complex was chosen for the conversion step in your liver.
I had my thyroid removed. Does this apply?
Yes. Your levothyroxine still has to be converted into T3, and up to 80% of that happens in your liver, so the step Conversion Complex supports is the same.
What if it doesn't work for me?
Then you don't pay. Every order has a 90-day money-back guarantee.
Email us, send back whatever's left (empty bottles are fine) and we refund you in full. We'd rather earn your next order than keep this one.
How long until I feel results?
Most women notice something in the first week, usually sleep, and less of that wired-but-exhausted feeling by mid-afternoon. Brain fog and energy tend to shift around weeks 3 to 4.
Metabolism, weight, hair and skin come later, usually weeks 6 to 8, with the full benefit by 90 days. Every woman is different, and the guarantee covers the whole 90 days.
Should I tell my doctor?
Yes, it's a good idea. The full label is in the "See what's inside" button at the top of the page, with all six ingredients and every dose listed.
If you take other prescriptions, like a statin or a blood pressure pill, show the label to your pharmacist as well.
Is it safe to take with my other supplements?
Yes. The selenium is L-selenomethionine, the well-absorbed form, at 50 mcg. That's a supportive dose, well under the 400 mcg daily upper limit. The rest of the formula is botanical.
If you already take a separate selenium supplement, put the two labels side by side so you're not doubling up. Your pharmacist can check that in about a minute.
Are there any side effects?
Most women have none, and there are no stimulants in it.
Some notice their digestion change in the first week or two. If your stomach is sensitive, start with one capsule a day for the first week, then go to two.
I'm scared to hope again.
We know.
You've been told your labs are normal while your hair was coming out in the shower. You've been handed a higher dose and told to wait three months. You've already tried the selenium, the iron, the B12, the gluten-free thing.
We can't promise you a miracle. What we can promise is that if it does nothing for you, you pay nothing. The only thing you risk is another 90 days of exactly what you have right now.
How long does shipping take?
Every order ships tracked, and most leave the next business day. Delivery in the US then takes 3 to 7 business days. Shipping is $3.99, and free on orders over $85.
Still wondering? Email support@phasea.co and a real person answers, usually within 24 hours.
90-day money-back guarantee
Use every capsule. If it isn't for you, email support@phasea.co, send back whatever is left (empty bottles are fine) and we refund you in full.
