Why You Need Primaldose® Cutting Drops? +

If the scale keeps climbing on 1,200 calories, the energy is gone by 2pm, and you're tired of hearing it's just your age — primaldose® was made for you.

Your thyroid makes T4: a storage hormone. It does nothing until your body converts it into T3 — the hormone your metabolism actually runs on. That conversion needs selenium, and years of dieting and stress quietly starve it. That's why the weight stays, no matter how little you eat. primaldose® feeds the conversion at the verified 2:1 selenium-to-iodine ratio — 10 nutrients, one sublingual dropper, 30 seconds under the tongue.†

Ten nutrients. One dropper. Thirty seconds every morning.

Already on levothyroxine? It works hand in hand with it — your prescription delivers the T4, primaldose® helps your body actually use it.

How Does It Work? +

Your thyroid (and your levothyroxine) makes T4 — the storage hormone. It’s inactive until your body converts it to T3, the active form that runs your metabolism. That conversion needs selenium, and a specific selenium-to-iodine ratio. Under stress or chronic dieting, your body makes Reverse T3 instead — a blocked copy that jams the receptors. primaldose gives your body all ten nutrients the conversion needs, in the 2:1 ratio, absorbed under the tongue.

Complete Ingredient List & Why Each Matters +

All 10 actives — exact doses, printed on the label:

  • Selenium (200 mcg) — Builds the deiodinase enzyme that converts T4 into active T3. Most women with thyroid issues run low.
  • Iodine (100 mcg) — the critical 2:1 ratio — The hormone building block, dosed at exactly half the selenium so it supports production without triggering an autoimmune flare.
  • Zinc (15 mg) — Lets your cells actually use the T3 you make.
  • L-Tyrosine (500 mg) — The amino acid your thyroid builds hormone from. Supports mental clarity.
  • Ashwagandha — KSM-66® (300 mg) — The branded, clinically studied extract that lowers the cortisol driving Reverse T3.
  • Vitamin B12 (100 mcg, methylcobalamin) — Active form. Hits the fatigue directly.
  • Magnesium (50 mg) — Required cofactor for the T4→T3 conversion.
  • Copper (1 mg) — Balances the zinc so it keeps working.
  • Manganese (2 mg) — Protects thyroid tissue from oxidative wear.
  • Vitamin D3 (1000 IU) — Calms the immune activity behind Hashimoto’s.
Recommended Use +

Take one full dropper each morning — shake well, squeeze the drops under your tongue, hold for 30 seconds, then swallow. No water, no food needed. Consistent daily use leads to the best results.

Most women notice the energy first — usually within the first 2 weeks. The scale typically follows in weeks 3–6.

Do You Offer a Guarantee? +

Yes! All Primaldose® orders are backed by our 60-day money-back guarantee.

Join Over 17,000+ Women Who Got Their Body Back

My wedding ring fits again for the first time in two years. My face isn’t puffy — I 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 had “work done.” Nope. I just finally fixed the Reverse T3 problem no doctor would look at.
Down 14 lbs. I was eating 1,200 calories and gaining — the scale finally started moving the other way. My body isn’t fighting me anymore.
Nine years on levothyroxine and I was scared to add anything. My doctor just shrugged — ‘your labs are fine.’ I wasn’t fine. Now it’s 30 seconds under my tongue with my morning coffee: my pill does its job, this does the rest. Down 9 lbs since March, and I’m not freezing in a warm house anymore. Wish the dropper were bigger — that’s my only complaint.
My hair was in the shower drain every morning and nobody could tell me why. ‘Stress,’ they said. Three months on these drops and my hairdresser asked what changed. Down 11 lbs too — without counting a single calorie. It’s not magic, I still watch what I eat. But my body finally responds again.

Every dose printed. Every batch tested. Every drop guaranteed.

Reason 1

The Studies Back the Weight Loss

In a 12-week study, 76% of women lost weight without cutting calories. The mechanism: your pill and your thyroid deliver T4 — the storage form. Selenium converts it into T3 — the hormone that actually burns fuel. These drops feed that conversion at the verified 2:1 selenium-to-iodine ratio.

Reason 2

Clinically Dosed, Not Underdosed

No trendy blends, no sprinkled-in doses. Selenium at 200mcg, L-tyrosine at 500mg, KSM-66® ashwagandha at 300mg — the doses the studies actually used, across all 10 nutrients. And every one of them is printed on the label.

Reason 3

Works With Your Levothyroxine

This isn’t a replacement for your prescription — it’s the support crew. Your pill delivers the T4. These drops supply the minerals your body needs to actually use it. Completes, not competes.

Reason 4

30 Seconds Under the Tongue

Years of thyroid trouble usually come with a worn-down gut — pills lose potency before they reach your blood. A dropper held under the tongue absorbs directly into the bloodstream. No capsule, no reflux, nothing to digest.

Reason 5

No 7-Day Miracle. A 60-Day Guarantee.

Hormone conversion doesn’t reset in a week — most women feel the shift in weeks 3 to 6. That’s why every bottle carries a 60-day money-back guarantee: take every drop, and if the scale hasn’t moved, send the empty bottle back.

Frequently Asked Questions

Find answers to common questions about our product, shipping, returns, and more.

How long until I see results? +

Most women feel steadier energy in the first 1–2 weeks; the scale usually starts moving by week 3–4. Reverse T3 takes 2–3 months to fully clear, which is why we suggest the 3-month bundle.

Is it safe for Hashimoto’s or other autoimmune conditions? +

The iodine is deliberately dosed at half the selenium (the 2:1 ratio) specifically to support the thyroid without the flare risk of high-iodine formulas. As always, check with your doctor if you have an autoimmune condition.

What if I’ve tried other thyroid supplements that didn’t work? +

Most are capsules that pass through the damaged gut, or they’re iodine-heavy and under-dose the selenium that actually drives conversion. primaldose is sublingual, in the 2:1 ratio, with all 10 cofactors. Different mechanism, different result.

Can I take it with my thyroid medication? +

Yes. It’s designed to support the conversion step your levothyroxine can’t do on its own. It contains no thyroid hormone. Take it a few hours apart from your pill, and never stop your prescription without your doctor.

Why liquid instead of pills? +

With Hashimoto’s, gut absorption is often compromised — capsules can pass right through. A sublingual liquid absorbs under the tongue, straight into the bloodstream.

How do I take it? +

One dropper under the tongue each morning, hold 30 seconds, swallow. That’s it.
