ThyroBase AM + PM System

We never add iodine, kelp or iodised salt to ThyroBase. The only iodine in it is a trace that comes naturally with its greens, chiefly the spirulina, a freshwater algae rather than a sea vegetable like kelp.

That difference is the whole point. Kelp and seaweed carry high, unpredictable iodine, which is exactly what people with thyroid conditions are told to watch. Freshwater spirulina carries only a trace, less than you would find in a single egg. A test will still detect it because it comes from real food, but nothing is added on top of it.

That is what makes ThyroBase appropriate for people who have had a thyroidectomy or RAI therapy, and for people with Hashimoto’s, where added iodine is the thing to avoid.

ThyroBase is built to sit alongside your thyroid medication, not to act on your thyroid hormones. It contains no added iodine and no kelp, with no added goitrogens, no glandular extracts and no hormonal compounds, so nothing in it is designed to raise or lower your TSH, T4 or T3. It also has no added biotin, so it will not interfere with your thyroid test results the way high-dose biotin supplements can.

The one thing that matters is timing. If you take thyroid medication, take it first on an empty stomach, then your AM serve at least 4 hours later, so minerals like iron never interfere with how your medication absorbs. As with anything you add, keep your prescriber in the loop.

Fair question. ThyroBase started as something Mum needed after thyroid cancer took her thyroid, so we built it together, held to the standard you would want for someone you love long before it was a product.

It was co-formulated with qualified naturopaths, dietitians, research nutritionists, food scientists and oncology pharmacists, made in Australia to FSANZ standards, and third-party tested. And every order is backed by the 60-Day Empty Pouch Promise: empty the pouches, and if you don't feel a real shift we refund what you paid. The risk sits with us, not you.

AM is Pineapple + Cardamom. Bright, lightly spiced, closer to a tropical smoothie than a supplement. Mix one AM serve (40g) into 250 to 300ml of cold water or oat milk.

PM is Chocolate + Cinnamon, with real cocoa and vanilla bean. A warm, gentle cocoa you stir into warm water or warm oat milk about 45 minutes before bed.

Both are food-style powders with no synthetic sweeteners, designed as a daily ritual you keep rather than a chore you push through. AM lands as a late-morning shake once your medication window has cleared. PM is the signal your day is done.

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, with no gluten-containing ingredients, and production runs dedicated gluten-free controls. If you have coeliac disease and would like batch documentation before starting, email hello@thyrobase.com.

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.

The System is designed around a build: the first 2 to 3 weeks settle the AM and PM rhythm in, and nutrient reserves keep building from there over weeks and months of consistent use. The Promise gives you a full 60 days to judge it on your own body.

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

Tell them exactly what it is: food-style nutritional support designed to sit alongside your treatment, not a medicine and not a replacement for it.

The three facts they will usually want. ThyroBase contains no added iodine, no kelp, no glandular extracts and no hormonal compounds, so nothing in it is designed to raise or lower your TSH, T4 or T3. It has no added biotin, so it won't interfere with thyroid test results the way many multivitamins can. And if you take thyroid medication, the AM serve is taken at least 4 hours after it, clear of the absorption window.

The full ingredient list and both nutrition panels are on this page. Plenty of people simply show their specialist the label at their next appointment, and we encourage exactly that. Your medication and your care team always come first.

Yes. ThyroBase is food-style nutrition built around the nutritional needs that change with a thyroid condition, whether or not you take medication. Nothing in it acts on your thyroid hormones, and it is not a treatment for anything.

If you do take thyroid medication, timing matters: medication first, then the AM serve at least 4 hours later, because the AM formula carries minerals. If you don’t, it is simpler still: AM with breakfast, PM about 45 minutes before bed.

As with anything you add, talk to your doctor, especially if you have been told you need medication. ThyroBase never replaces treatment you have been prescribed.
