Designed to sit alongside your levothyroxine, not interfere with it.

How to use

Morning. Take your thyroid medication first, on an empty stomach, with water only. Wait at least 4 hours. Then mix one AM serve (40g) into 250 to 300 ml of water or oat milk. AM lands as a late breakfast, brunch, or stand-alone shake once the 4-hour window has cleared.

Evening. Around 45 minutes before bed, mix one PM serve (40g) into warm water or warm oat milk. Best taken consistently around the same time each night.

Daily. One AM serve, one PM serve. Each box contains 4 pouches (2 AM + 2 PM), a 28-day supply.

Science & certifications

Every ingredient sits on top of peer-reviewed research relevant to its role: selenium and T3/T4 ratio, methylcobalamin and energy, ferritin and hair shedding, magnesium and sleep, glycine and sleep onset, probiotics and the thyroid-gut axis.

The 60-Day Empty Pouch Promise

60 days. Empty the pouches.

Take ThyroBase daily for 60 days. Empty all 8 pouches if you need to. If you don't feel a real shift in your day to day, email us and we'll refund both months in full. No return shipping. No awkward questions. The Promise applies to subscription only.

The only thing you risk is finding out it works.

What 60 days actually looks like

From day one to your first shift.

Real nutrition takes real time. Here's what most people notice on the AM + PM rhythm, and what the long game looks like.

Day 1 to 14

Lock in the rhythm.

AM 4+ hours after your medication, PM 45 minutes before bed. Your body finds the cadence.

Week 3 to 6

Early shifts.

Most people notice sleep depth and steadier daytime energy first. Subtle but real.

Week 8 to 12

Clearer signal.

Cofactor reserves build. Mental clarity, hair density and recovery often follow on consistent use.

Day 90 and beyond

Your new normal.

Cofactor reserves stable. Sleep dialled in. AM and PM as part of your rhythm. The long game thyroid nutrition was meant to be.

Individual results vary. Underlying ferritin, thyroid stability and consistency all influence timing. The Promise is designed to give you the time you actually need.

Ready when you are

Lock in early access.

First in line when ThyroBase opens for orders. Pre-launch pricing locked at $369/month subscription. The Promise stands from day one.

The real comparison

Less than your morning coffee.

A premium flat white costs around $6 in Australia. ThyroBase is $6.39 per serving. The difference is what you get back: complete clinical nutrition, specifically formulated to fill the gaps your medication doesn't cover.

A morning coffee
$6.00

A flat white. One serve. Caffeine and sugar.

vs.
A ThyroBase serving
$6.39

Complete daily nutrition. Bioactive forms, clinical doses, designed for life with a thyroid condition.

And here's what one serve replaces

What you're probably buying separately Monthly cost
A clean plant protein (25g per serve)$55 to $70
A greens or micronutrient powder$80 to $120
A magnesium sleep formula$30 to $45
A probiotic + prebiotic$40 to $60
A separate selenium / B12 / iron stack$30 to $50
Stacked monthly$235 to $345

ThyroBase is $369 a month on subscription, $399 one-time for the only AM and PM system formulated specifically for life with a thyroid condition. Iodine-free. Kelp-free. Goitrogen-free. Designed to sit alongside your thyroid medication, not interfere with it.

You're not paying more. You're paying for one thing that actually fits.

The substance difference

Why ThyroBase is engineered differently.

Most premium plant protein powders deliver 20 to 25 grams of protein per serve. ThyroBase delivers 47 grams of protein per day, across a clinically-designed AM and PM system built to support your body's natural rhythm, morning and night.

Built for the right person

Is ThyroBase right for you?

It's built for you if

  • You've had a thyroidectomy or live with a thyroid condition (Hashimoto's, hypothyroidism)
  • Your tests are "in range" but you don't feel like yourself
  • You've stacked supplements before and aren't sure what's helping
  • You want one structured ritual, not five pill bottles to manage

It's not for you if

  • You have an overactive thyroid (hyperthyroidism, Graves')
  • You're pregnant or breastfeeding
  • You're looking for a thyroid medication replacement
  • You want a stimulant-based energy boost

Always speak with your healthcare professional before starting any supplement.

The formulation difference

Why our ingredients cost more.

ThyroBase is FSANZ compliant and co-formulated with dietitians and oncology pharmacists. Where most supplements use the cheapest form of every nutrient, we use the form your body actually recognises and uses.

A note from Manny

We built ThyroBase for Mum.

She had a thyroidectomy after thyroid cancer that had spread to her lymph nodes. Her tests came back perfect, and she was wrecked. Exhausted, foggy, not herself. I looked for a supplement built for her, found nothing without iodine or kelp or fillers, so we built it ourselves over 18 months of research, formulation, and review.

If you're reading this and any of the above sounds like you, I want you to feel like ThyroBase was built for you too. Because it was. Try it for 60 days. If it doesn't help, the guarantee makes sure you don't lose anything.

Manny.Co-founder, ThyroBase

Your questions

Everything you need to feel confident.

Full transparency on what’s in ThyroBase, why each ingredient is included, and how the AM & PM system fits alongside your thyroid medication.

Why are there two separate formulas, AM and PM?

The two-formula system delivers the right nutrients at the right time, the way your body actually works.

AM supports energy, metabolism, and immune function with protein, B12, selenium, zinc, and Vitamins D3, K1, and C.

PM supports muscle recovery, sleep quality, gut health, and overnight restoration with protein, magnesium citrate, glycine, chamomile, passionflower, and probiotics.

Magnesium sits in the PM formula because it supports relaxation and sleep. B12 and selenium are in the AM formula to support energy when you need it most. No other plant protein system on the Australian market is designed around this daily rhythm.

When should I take the AM formula alongside my thyroid medication?

ThyroBase was designed with thyroid medication timing built in from day one.

Take your medication first thing in the morning on an empty stomach, as prescribed. Enjoy your AM formula 4+ hours later. A simple routine: medication at 7am, AM ThyroBase at 11am, PM ThyroBase 1 to 2 hours before bed.

This timing ensures your medication absorbs fully before any minerals or protein interact with it. No compromise on either side.

Does ThyroBase contain iodine?

No, and this is a deliberate formulation decision that protects people with thyroid conditions.

Many generic thyroid support supplements contain iodine, which is inappropriate for people who have had a thyroidectomy or RAI therapy. After thyroidectomy, the thyroid gland is no longer present to use iodine. For people who have had RAI therapy, added iodine can interfere with ongoing management.

ThyroBase was specifically formulated to be safe for post-thyroidectomy and post-RAI care. Iodine-free by design.

Why is Vitamin C at 503% of the RDI? Is that safe?

Yes. This figure reflects how conservative Australia’s RDI for Vitamin C is, set at around 45mg per day. The actual amount in your AM ThyroBase is 201mg, a very reasonable and safe dose.

Vitamin C is water soluble. Your body uses what it needs and naturally flushes the rest. Australia’s upper safe limit is 2,000mg per day. ThyroBase delivers 201mg, one tenth of that threshold.

The Vitamin C comes from natural acerola and amla, whole-food sources that absorb gently.

How much should I take each day?

For most people, 40g AM and 40g PM daily is the right target. That provides approximately 44g of complete plant protein plus a comprehensive array of vitamins and minerals across the day.

If you are new to plant protein or have a sensitive digestive system, starting with a half serve of each and building up over 1 to 2 weeks is a comfortable approach.

Stay well hydrated. The combined fibre content of both formulas supports digestive health and works best with good fluid intake.

Is ThyroBase suitable for vegans? Gluten-free?

Yes to both. All protein sources are 100% plant-based, and the Vitamin D3 is derived from algae. Both formulas are fully vegan.

Both formulas contain 0.0g of gluten per serve. ThyroBase is fully suitable for people with gluten sensitivity or coeliac disease.

How can I track the difference ThyroBase is making?

If you already have regular tests with your endocrinologist or GP, continue your existing schedule and share your results over time. ThyroBase is designed to complement those results, not complicate them.

Many people notice meaningful differences in energy, sleep quality, and mental clarity within the first 2 weeks. Measurable markers like Vitamin D, B12, ferritin, magnesium, and selenium often improve over 3 to 6 months of consistent use.

You do not need a test to start. Your existing monitoring schedule with your healthcare team is all you need.

Every purchase includes our Foundation Tracker. A free 16-page PDF designed for exactly this. A daily log for your routine, your energy, your sleep, and how you actually feel as you go. Preview the tracker →

Should I check with my doctor before starting?

For most people, no special consultation is needed. We do recommend a quick check with your healthcare provider if you:

Have a known legume allergy (both formulas contain pea and faba bean). Have a known ragweed or daisy family allergy (the PM formula contains chamomile). Are taking prescription blood-thinning medication such as warfarin (due to Vitamin K1 in the AM formula). Are taking prescription sedatives (due to passionflower in the PM formula). Are pregnant or breastfeeding. Have a diagnosed kidney condition.

These are standard, responsible disclosures. The vast majority of people will have no concerns at all. ThyroBase is a food supplement, not a medicine, and always sits alongside your existing healthcare plan.

Real reviews coming July 2026

We won't fake this part.

Real customer reviews will land here once people have lived with the system for 60+ days. We won't seed this section with anything else. No paid testimonials, no friend-of-the-founder quotes, no AI-generated stories.
