Lauren J.
"Wish I'd found this 3 years ago instead of suffering while my doctor kept increasing my Levothyroxine dose. Peak Form fixed in weeks what years of medication adjustments couldn't."
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.
What Results Can I Expect?
+
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.

Here's What Peak Form Customers Think
Finally Found relief
Five years on Synthroid with perfect labs but feeling terrible. Peak Form gave me my energy back in just 3 weeks. My doctor was shocked when I asked to reduce my medication because it was finally working.
Worth It!
After years of feeling exhausted and gaining weight on 1200 calories, these drops changed everything. My brain fog lifted, periods normalized, and I finally sleep through the night. Worth every penny.

Peak Form Rules!
Started taking Peak Form drops three months ago for my thyroid issues. My hair stopped falling out, energy came back, and I've lost 12 pounds without changing anything else. This stuff actually works.

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 90-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.
