Every ingredient earned its place.
Each one chosen for its form, its dose, and the research behind it. No proprietary blends. No fairy dust. No filler.
Bioactive forms. Premium sources. Researched doses.
Most thyroid-targeted supplements use the cheapest form of every nutrient. We co-formulated ThyroBase with qualified naturopaths, dietitians, research nutritionists, food scientists, and oncology pharmacists around a single question: would I take this every day, for life. Every form below is the answer.
The morning cofactors.
The cofactors involved in converting and using thyroid hormone across the day.
Pineapple · CardamomSelenium
Selenomethionine · chelatedAn essential trace mineral.
Bioavailable selenomethionine at a researched dose, not a megadose. Selenium powers the body’s antioxidant selenoenzymes.
Vitamin B12
MethylcobalaminA water-soluble B vitamin.
Bioactive methylcobalamin, no conversion needed. Supports normal energy metabolism and nervous system function.
Plant-Based Iron
Naturally occurring · food-formAn essential mineral.
No added iron compound. It comes from the food base itself: pea and pumpkin seed proteins, spinach, spirulina. Ferritin is one of the strongest correlates of hair shedding and energy, and food-form iron is gentle on the gut.
Zinc
Zinc gluconateAn essential trace mineral.
Zinc gluconate at a researched dose. Supports immune function and the integrity of skin, hair and nails.
Vitamin D3
Plant-source D3A fat-soluble vitamin, sourced from plants.
A daily top-up to support what sunshine and diet provide. Plant-sourced D3 supporting immune function and wellbeing.
Vitamin C
Acerola cherry extractA water-soluble vitamin, here from whole acerola cherry.
Whole-food source with bioflavonoid cofactors intact. Supports absorption of the naturally occurring iron in the AM base.
Plant Protein Matrix
24.9 g · four plant sourcesA plant protein blend from four sources.
Yellow pea, brown rice, faba bean, pumpkin seed. Soy-free, complete amino acid profile.
The evening repair.
Nutrients chosen for the evening half of the day. No added caffeine. No melatonin. No sedation.
Chocolate · CinnamonMagnesium
Magnesium citrateAn essential mineral.
The most documented mineral for sleep onset and quality (Abbasi, 2012, RCT). Citrate form, well-absorbed.
Glycine
The FSANZ permitted maximumAn amino acid.
Studied for its effect on core body temperature and sleep onset, and a building block of collagen (Yamadera, 2007, RCT). We include the most FSANZ permits in a food, alongside the glycine naturally present in the protein base.
Chamomile
Chamomile flower powderA traditional evening botanical.
Apigenin is the chamomile compound most studied for its calming role. Many thyroid people describe a "wired but tired" pattern at night.
Passionflower + Grapeseed
Botanical extractsTwo botanical extracts.
Passionflower is studied for anxiety-driven sleep onset and sits alongside chamomile and glycine in the PM blend. Grapeseed brings OPC polyphenols for antioxidant support.
Probiotics
A real probiotic blend, in every evening serveLive cultures, included in every evening serve.
Chosen for gut support, not for chasing the biggest number on a label. Paired with prebiotic fibre, because live cultures need fuel to do their job.
Prebiotic Fibre
Acacia gum + psyllium huskTwo soluble plant fibres.
Feeds the live strains overnight and supports gut barrier function, which matters for hormone conversion.
Real flavour, not chemistry.
The flavouring, sweetening, and finishing ingredients are held to the same standard as the actives. Whole-food sources. No artificial sweeteners. No flavour chemicals.
Cacao
Polyphenol-richThe seed of the cacao fruit, fermented and ground.
The heart of PM cocoa flavour. Naturally rich in magnesium and antioxidant polyphenols.
Vanilla Bean
Whole vanilla beanWhole ground vanilla bean.
Real vanilla bean, not synthetic flavouring. Adds depth and warmth to PM.
Cinnamon
Whole-spiceA whole warming spice.
Adds the warm-spice signature to PM. A traditional warming spice that makes the chocolate flavour read as dessert, not medicine.
Nutmeg
Whole-spiceA whole warming spice.
A pinch in PM for warmth and depth.
Lucuma
Low-glycemic Peruvian fruitA Peruvian fruit, dried and milled.
Low-glycemic Peruvian fruit. Caramel-toffee sweetness without the spike.
Monk Fruit

Zero-calorie, fruit-derived sweetness. No glycemic impact, no artificial chemistry.
Himalayan Salt
Pink mineral saltA naturally pink mineral salt.
Trace minerals and electrolyte balance. A pinch, not a season.
Greens Blend
Kale, spinach, broccoli sproutThree named culinary greens.
Named, not hidden: kale, spinach and broccoli sprout at culinary levels. Naturally rich in chlorophyll and trace micronutrients.
Spirulina
Freshwater blue-green algaeA freshwater blue-green algae.
Algal protein and pigments. Iron-rich. Quiet plant nutrition in the AM blend.
What we deliberately left out.
What's not in the pouch matters as much as what is. Each exclusion has a reason, most tied to thyroid medication absorption or autoimmune triggers.
Co-formulated with qualified naturopaths, dietitians, research nutritionists, food scientists, and oncology pharmacists.
Every ingredient and dose was reviewed by people who actually understood the brief. Manufactured in Australia to FSANZ standards.
Every ingredient sits on top of peer-reviewed research.
