How Does It Work?
+
Peak Form delivers the precise 2:1 selenium-to-iodine ratio your body needs to convert inactive T4 hormone into active T3. Unlike pills that barely absorb (10-15%), our liquid formula goes straight into your bloodstream, delivering conversion cofactors directly to your liver and tissues where thyroid hormone activation actually happens. This reactivates the enzymes that long-term thyroid medication depletes.
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.

Wedding ring fits again for the first time in 2 years. Face isn't puffy anymore—I actually have cheekbones again. Down 13 lbs in 8 weeks and my clothes fit like they used to. My sister saw me at Thanksgiving and asked if I'd gotten 'work done.' Nope. Just finally fixed the Reverse T3 problem no doctor would acknowledge.

Lost the bloat in week one—woke up with a flat stomach for the first time in forever. Lost 7 lbs by week four. Lost the guilt about eating by week six. I used to feel like I had to apologize for every bite of food I put in my mouth. Now I eat dinner with my kids without mentally calculating if I 'deserve' it. That freedom is priceless.

Down 14 lbs in 6 weeks eating 1,800 calories. After 3 years of gaining weight on 1,200 calories a day, I almost cried when the scale finally moved. My doctor kept telling me to 'eat less and exercise more'—I was already starving myself. Turns out my body wasn't broken. My Reverse T3 was. Finally feel like weight loss is possible again.

Lost 11 pounds in the first month without changing anything else. My endo asked what I changed at my last appointment. I just smiled. After years of her telling me my 'labs look fine' while I gained 40 lbs, it felt good to finally prove something WAS wrong. Peak Form fixed what she couldn't even diagnose.

Coworkers keep asking if I got on Ozempic. Nope—just finally fixed what was actually broken instead of masking the symptoms. Down 15 lbs, no nausea, no injections, and I'm eating more than I have in years. They want to know my secret. I tell them: stop starving yourself and fix your Reverse T3.

15 years watching women suffer. ONE formula to fix it.
For decades, I watched my patients suffer. Doctors kept prescribing more levothyroxine while ignoring the real problem. So I dedicated my career to studying one thing: how to actually clear Reverse T3. That's why I formulated Peak Form.
Selenium (200mcg)
+
Powers the deiodinase enzymes that convert inactive T4 into active, fat-burning T3. Without adequate selenium, your thyroid medication literally cannot become the hormone that burns calories. 89% of hypothyroid women are deficient. Clinical studies show 200mcg is the optimal therapeutic dose—most supplements use 50mcg (label decoration).
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 metabolism.
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.
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. 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 you worse.
Zinc (15mg)
+
You can have perfect T3 levels, but if your cells can't receive it, nothing happens. Zinc clears jammed thyroid receptors and restores cellular sensitivity so your body actually USES 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.
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
No More Crying At The Scale Every Morning
Hypo for 5 years, tried 3 different endocrinologists. All said labs were fine (TSH 2.9) despite gaining 72 pounds. Was doing IF 18:6, under 1,200 calories, cutting carbs - nothing worked. Some days I'd just cry looking at the scale. Found Peak Form after searching 'why can't I lose weight on levothyroxine' at 2am. The Reverse T3 explanation made everything click. 14 weeks in: lost 28 pounds, eating breakfast again (!), and my anxiety is so much better. My mom asked what I'm doing differently because I look happier. It's because I finally have my life back.
First Time The Scale Moved Since 2021
After 3 years of eating 1,200 calories and gaining weight, I was ready to give up. My endocrinologist kept saying my TSH was 'perfect' at 2.8, but I knew something was wrong. I'd gained 67 pounds since my diagnosis and was tracking every bite in MyFitnessPal. Found Peak Form through a thyroid support group on Facebook where women were talking about Reverse T3. I'm down 19 pounds in 10 weeks - eating 1,700 calories! First time I've lost weight since 2021. My husband said I seem like myself again. Still have 40+ to go but finally have hope.
I Cried When My Old Jeans Fit Again
I'm 52 and hypothyroid for 8 years. Tried everything - keto, intermittent fasting, even ate one meal a day for months. Nothing. My doctor actually told me to 'accept this is your new normal.' Started Peak Form in September after reading about the Reverse T3 issue (why don't doctors test for this??) Down 24 pounds and eating normal meals with my family again. The brain fog lifting was unexpected - I can actually focus at work past 2pm. Not gonna lie, I cried when I fit into my old jeans last week.
Finally Eating Dinner With My Kids Without Gaining 3 Pounds Overnight
TSH 'normal' at 3.2 but gained 55 pounds in 18 months. Was basically living on salads and protein shakes, maybe 900 calories some days. My doctor suggested Ozempic which made me furious - I don't need appetite suppression, I'm barely eating! Peak Form was my last try before giving up completely. Week 3 I lost 4 pounds eating actual food. Week 8 down 14 pounds total. I can eat dinner with my kids without gaining 3 pounds overnight. Still exhausted some days but nothing like before. Finally feel like my body isn't fighting against me.

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
How long until I see results?
+
Most customers notice improved energy and reduced brain fog within 1-2 weeks. Significant symptom reduction (hair regrowth, weight loss, stable mood) typically occurs by 2-3 months as your body rebuilds mineral stores and optimizes thyroid conversion.
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.
