How Does It Work?
+
Your medication gives you T4 — but that's the inactive hormone. Your body still has to turn it into T3, which is the one your hair follicles actually need to grow. But with Hashimoto's, stress, and missing nutrients, your body turns that T4 into a broken version called Reverse T3 instead. It blocks the real stuff from reaching your hair. The follicle starves and the hair falls out — even when your bloodwork looks 'normal.' Peak Form gives your body what it needs to start making the real T3 again so it can actually reach the follicle and wake it back up
Is It Safe With My Medications?
+
Yes, Peak Form is designed to work WITH your thyroid medication, not replace it. Our formula enhances your body's ability to convert and use the thyroid hormone from your prescription. Many customers taking Synthroid, Levothyroxine, or NDT report better results from their existing medication.
Important: If you're on thyroid medication, share our ingredient list with your doctor. As your conversion improves, you may need dosage adjustments.
Not recommended for hyperthyroidism without medical supervision.
Proven Ingredients For Thyroid Health
+
Complete Ingredient List & Why Each Matters:
Selenium (200mcg)
Essential for T4 to T3 conversion. Your body needs selenium to build deiodinase enzymes that activate thyroid hormone. Most people with thyroid issues are severely deficient.
Iodine (100mcg)
The building block of thyroid hormones. Our precise 2:1 selenium-to-iodine ratio ensures optimal hormone production without triggering autoimmune flare-ups.
Zinc (15mg)
Critical for thyroid receptor function. Even with adequate hormone levels, zinc deficiency prevents your cells from actually using the thyroid hormone available.
L-Tyrosine (500mg)
The amino acid precursor your thyroid uses to manufacture hormones. Supports mental clarity and helps combat brain fog.
Ashwagandha (300mg)
Adaptogenic herb that helps regulate stress hormones (cortisol) which can block thyroid function. Reduces inflammation and protects thyroid tissue.
Vitamin B12 (Methylcobalamin - 100mcg)
Active form for better absorption. Supports energy production and helps reverse the fatigue associated with poor thyroid function.
Magnesium (50mg)
Required for over 300 enzymatic reactions including thyroid hormone production and T4 to T3 conversion.
Copper (1mg)
Works synergistically with zinc for optimal thyroid receptor sensitivity. Proper copper-zinc balance is crucial.
Manganese (2mg)
Supports thyroid hormone synthesis and protects against oxidative stress that damages thyroid tissue.
Vitamin D3 (1000 IU)
Modulates immune function and reduces thyroid antibodies in autoimmune conditions like Hashimoto's.

my hair looked like hay. dry, brittle, ratty — even felt dry when it was wet. the texture just completely changed and i remember thinking the product i used for years changed but it wasnt the product it was this disease. so much of who i am was connected to my hair. i was terrified to even brush it bc i would fill my whole brush up with hair. around week 5-6 on peak form it started feeling less brittle. like it wasnt breaking every time i touched it. by month 3 the shedding in the shower slowed down — i stopped dreading washing my hair. around month 5-6 the texture started coming back?? like actual soft hair not straw. im at 8 months now and i can actually wear it down without trying to conceal the damage. i dont straighten it to hide it anymore. theres comfort in finally feeling like myself again

i used to have hair so thick i could barely twist a hair tie around my ponytail twice. then it got to where the hair tie would wrap around 4 times. i could see my ponytail getting visibly smaller with every wash. i tried biotin for 8 months and nothing helped. raised my ferritin to 85. ate gluten free for over a year — cut out everything, ate in misery, and my hair STILL fell out. i was terrified to wash my hair. i would only wash once a week hoping it would slow the loss. shedding slowed around month 2 on peak form. not gone but the fistfuls turned into strands. baby hairs showed up month 3-4 along my hairline. by month 7 my hair had weight to it again instead of being thin and wispy. im a little over a year now and its the thickest its been since before my diagnosis. i dont dread the shower anymore. i dont pick hair off my clothes all day. i just want other women to know theres hope bc i had given up

you could literally see through my hair. my scalp was visible everywhere not just my part. i cant even look at myself in the mirror anymore is what i used to say every single day. i stopped letting people take photos of me. my social life went down bc i didnt want to leave the house. every time i got ready i had a mini breakdown. i was looking into wigs. ferritin was fine. tsh was fine. doctors kept saying everything looks normal. around week 5-6 on peak form i ran my fingers through my hair and less came with it. i was scared to believe it bc everything else had failed. month 3 i could feel baby hairs along the top of my head. its been 10 months now and you cant see my scalp anymore. i wore my hair down for the first time in over a year. i just wanted to feel normal and not think about it every second. i finally feel like a person again

What to Expect From Daily Peak Form Use Ahead
Week 1
First signs Reverse T3 is clearing: Less hair on your pillow in the morning. Energy returns without needing 3 coffees. The heavy exhaustion that makes you dread washing your hair starts lifting.
1 Month
Shedding starts to slow. Less strands on your clothes, less hair clogging the drain. Still shedding — but the clumps get smaller. Your nails may start feeling stronger. The texture of your existing hair starts feeling less brittle and dry.
2 Months
Noticeable reduction in daily shedding. You can run your fingers through your hair without that gut-punch of strands coming out. Baby hairs start appearing along your hairline and part. Your hairdresser might notice before you do.
3 Months
Reverse T3 clearing. Shedding normalizes to what it was before this nightmare started. Baby hairs are visible and growing. Hair texture improving — less straw, more softness. You might catch yourself looking in the mirror without flinching for the first time in months.
6 Months
Real regrowth filling in. Ponytail feels thicker. You stop obsessively checking the drain. The patches are filling. You start wearing your hair down again.
12 Months
Full growth cycle restored. Density returning. You recognize yourself in photos again. You stop planning your life around hiding your hair.
15 years watching women lose their hair — and their identity. ONE formula to fix it.
For decades, I watched my patients do everything right. They optimized their TSH. They raised their ferritin to 80. They cut out gluten, dairy, and every food they loved. They switched medications three times. And they still sat in my office crying because their hair wouldn't stop falling out. The problem was never their ferritin. It was never the diet. It was never the wrong medication. It was Reverse T3 — a broken version of thyroid hormone that blocks the real hormone from ever reaching the hair follicle. That's why I formulated Peak Form.
Selenium (200mcg)
+
Powers the deiodinase enzymes that convert inactive T4 into active, follicle-feeding T3. Without adequate selenium, your thyroid medication literally cannot become the hormone that keeps your hair in its growth cycle. 89% of hypothyroid women are deficient. Clinical studies show 200mcg is the optimal therapeutic dose — most supplements use 50mcg
Ashwagandha (300mg)
+
When you're stressed or dieting, cortisol forces your body to convert T4 into Reverse T3 (broken keys) instead of real T3. Clinically proven to reduce cortisol by 27.9% in peer-reviewed studies. Shuts down the Reverse T3 factory at the source so you stop making broken keys that jam your follicles.
L-Tyrosine (500mg)
+
The amino acid precursor your thyroid uses to manufacture T3 and T4 hormones in the first place. Like trying to bake bread without flour — most hypothyroid patients are depleted from years of metabolic stress. 500mg provides the raw material your thyroid desperately needs to feed your follicles.
Iodine (100mcg) – The Critical 2:1 Ratio
+
Your thyroid needs iodine to make ANY hormone. But here's what nobody tells you: too much triggers Hashimoto's flares — which means MORE shedding. The 2:1 selenium-to-iodine ratio is the only proven safe balance — enough iodine to support production, perfectly balanced with selenium to prevent autoimmune attacks. This ratio is why Peak Form works when other supplements made your shedding worse.
Zinc (15mg)
+
You can have perfect T3 levels, but if your follicles can't receive it, nothing happens. Zinc clears jammed thyroid receptors and restores cellular sensitivity so your hair follicles actually USE the hormones you're producing. 76% of hypothyroid women are deficient.
Vitamin D3 (1000 IU)
+
If you have Hashimoto's (90% of hypothyroid cases), your immune system is attacking your thyroid. Vitamin D3 modulates immune function and reduces thyroid antibodies so your thyroid can actually heal instead of being destroyed by friendly fire — ending the constant shedding cycles.
Liquid Delivery
+
Most thyroid patients have compromised digestive systems—low stomach acid, damaged gut lining, poor absorption. Pills pass through undigested. Peak Form's liquid formula absorbs directly through your mouth and stomach lining in minutes, bypassing your broken gut entirely. Goes straight to your liver where T4→T3 conversion actually happens. 10x better absorption than pills.
Women Who Were Told "Your TSH Is Normal" Share Their Results
I Stopped Counting The Hairs In The Drain
hashi's for 5 years. tried 3 endocrinologists. all said labs were fine (tsh 2.9) while i was pulling out fistfuls of hair every shower. i was washing my hair once a week hoping it would slow down the loss. i had tried biotin, iron supplements, expensive salon shampoos, rosemary oil — nothing. i was researching wigs at 2am when i found peak form. the reverse t3 explanation was the first thing that actually made sense to me. around week 6 i noticed less hair on my pillow. by month 3 my hairdresser said she could see baby hairs coming in along my part. im at 5 months now and the shedding has basically stopped. i actually washed my hair twice this week without crying. that sounds stupid but if you know you know.
First Time I Wore My Hair Down In Over A Year
after 3 years of my hair getting thinner and thinner i had basically accepted this was my life now. i was using toppik powder every single day just to leave the house. my scalp was showing through the top and i would plan my whole day around not being in direct light bc thats when you could really see it. found peak form through a thyroid support group on facebook. i didnt notice much the first month but around week 7-8 the daily shedding slowed down. less hair on my clothes, less on my desk at work. the baby hairs started around month 3 and i was scared to even acknowledge it. im at 8 months now and i dont use the toppik anymore. i wore my hair down at my daughters recital last month and my husband said he hasnt seen me do that in over a year. i cried when he said that.
I Did AIP For A Year And My Hair Still Fell Out
i cut out gluten dairy soy nightshades for over a year. ate in complete misery. couldnt go to restaurants anymore. my husband and i stopped eating together bc we couldnt have the same food. and my hair STILL fell out. my ferritin was at 82, my tsh was "perfect" and doctors had nothing left to tell me. peak form was honestly my last try before i gave up and bought a wig. the shedding slowed around month 2. by month 4 i could run my fingers through my hair without that sick feeling. im at 11 months now and my ponytail is thicker than its been in 3 years. its not where it was before hashimotos but i dont care. i eat normal food again and my hair is growing. thats all i wanted.
My Mom Cried When She Saw My Hair
im 26. ive been losing hair since i was 22. i tried everything — minoxidil made my scalp greasy and grew peach fuzz on my face so i stopped. spironolactone scared me bc of the thyroid interactions. biotin did nothing. every doctor told me my levels were fine and to "reduce stress" like yeah thanks thats helpful when im pulling clumps out in the shower. my hair was maybe 30% of what it used to be. i wore hats every single day. i deleted all my social media bc i couldnt look at old photos of myself. peak form took a while — i didnt see real change until month 3 when the baby hairs started. by month 6 the density was actually coming back. im at 13 months now and my mom visited last weekend and literally cried when she saw me bc she said i look like myself again. i look like myself again. thats everything.

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
How long until I see results?
+
Most women notice reduced shedding within 4-8 weeks. Baby hairs typically appear around month 2-3. Real thickness and regrowth usually become noticeable by month 4-6. Full hair growth cycles take 12+ months, so the longer you stay on it the more results you'll see. Hair that's falling out now died 3-6 months ago — so give it time for the new healthy growth cycle to kick in.
Can I take Peak Form with my thyroid medication?
+
Yes, Peak Form is designed to work alongside Synthroid, Levothyroxine, or NDT - not replace it. Our formula enhances your body's ability to convert and use thyroid hormone from your prescription. Many customers report better results from their existing medication and some have reduced their dosage with doctor approval.
Important: Always share our ingredient list with your doctor, especially if you're on thyroid medication.
Is it safe for Hashimoto's or other autoimmune conditions?
+
Yes. Our formula uses carefully balanced iodine levels (100mcg) that support thyroid function without triggering autoimmune flare-ups. The selenium and vitamin D actually help reduce thyroid antibodies. However, if you have hyperthyroidism or Graves' disease, consult your doctor before use.
Why liquid instead of pills?
+
Liquid delivers 10x better absorption than pills. Thyroid issues often cause digestive problems that prevent pill absorption. Our liquid bypasses your stomach and goes straight to your bloodstream where conversion actually happens - in your liver, kidneys, and tissues.
What if I've tried other thyroid supplements that didn't work?
+
We understand - most of our customers tried 5-10 supplements before Peak Form. The difference is our precise 2:1 selenium-to-iodine ratio that forces T4→T3 conversion, plus liquid delivery that actually absorbs. That's why we offer a 60-day money-back guarantee - you risk nothing trying it.
How do I take it?
+
Take one dropper (1ml) daily, preferably in the morning. You can take it directly under your tongue for fastest absorption, or mix it with water or juice. Take with or without food. If you're on thyroid medication, you can take Peak Form at the same time or separately - both work fine.
I've tried biotin, iron supplements, and special shampoos — nothing worked. Why would this be different?
+
Because those don't fix WHY the hair is falling out. Biotin gives building blocks but can't force a dormant follicle to grow. Iron supports blood flow but doesn't fix hormone conversion. Shampoos treat the surface, not the cause. If your body is turning T4 into Reverse T3 instead of active T3, no amount of biotin or iron will fix that. Peak Form targets the conversion problem itself.
