How Does It Work?
+
About 60% of your T4 to T3 conversion happens in your liver. But years of Hashimoto's inflammation overload the liver until it becomes sluggish. When that happens the T3 your follicles need never reaches your cells — even though your blood work looks normal. Peak Form supports the liver pathway and gives your body the minerals to power the conversion so T3 actually reaches your follicles.
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)
Powers the liver's T4 to T3 conversion pathway. Your liver needs selenium to build the enzymes that activate your thyroid hormone. 200mcg is the optimal therapeutic dose.
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)
Supports liver detoxification pathways and thyroid receptor sensitivity. Your liver needs zinc to properly process and convert thyroid hormones. 76% of hypothyroid women are deficient
L-Tyrosine (500mg)
The amino acid precursor your thyroid uses to manufacture hormones. Supports mental clarity and helps combat brain fog.
Ashwagandha (300mg)
Cortisol from chronic stress increases liver inflammation and further impairs conversion. Clinically proven to reduce cortisol by 27.9%. Lowers the inflammatory load on your liver so the conversion pathway can actually function.
Methylcobalamin - 100mcg
Clinical-grade methylcobalamin. A 2025 Nature Communications study found it directly protects liver cells from inflammatory damage and promotes liver tissue survival. Supports the liver pathway that converts your medication into the active hormone your follicles need.
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 liver conversion is restoring: 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
Liver pathway opening. Shedding normalizes.
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 their liver. Years of Hashimoto's inflammation had quietly overwhelmed it. The conversion pathway that turns their medication into the active hormone their hair needs had broken down. Their blood work showed normal T3 but it wasn't reaching their cells. That's why I formulated Peak Form.

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?
+
Goes straight to your liver where T4→T3 conversion actually happens.
What if I've tried other thyroid supplements that didn't work?
+
our formula supports the liver pathway first — which is where 60% of your conversion actually happens — then fuels it with the precise 2:1 selenium-to-iodine ratio.
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?
+
If your liver is too sluggish to convert T4 into cellular T3, no amount of biotin or iron will fix that. They're all just sitting in your blood while your cells starve. Peak Form supports the liver pathway first then fuels the conversion
