Every ingredient. Every reason.

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.

12Researched ingredients
100%Bioactive forms
0Added iodine, kelp, fillers
AM · Golden Morning

The morning cofactors.

The cofactors involved in converting and using thyroid hormone across the day.

Pineapple · Cardamom
AM Cofactor

Selenium

Selenomethionine · chelated
What it is:

An essential trace mineral.

A water-soluble B vitamin.

Why it’s in ThyroBase:

Bioactive methylcobalamin, no conversion needed. Supports normal energy metabolism and nervous system function.

AM Foundation

Plant-Based Iron

Naturally occurring · food-form
What it is:

An essential mineral.

Why it’s in ThyroBase:

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.

AM Cofactor

Zinc

Zinc gluconate
What it is:

An essential trace mineral.

Why it’s in ThyroBase:

Zinc gluconate at a researched dose. Supports immune function and the integrity of skin, hair and nails.

AM Cofactor

Vitamin D3

Plant-source D3
What it is:

A fat-soluble vitamin, sourced from plants.

Why it’s in ThyroBase:

A daily top-up to support what sunshine and diet provide. Plant-sourced D3 supporting immune function and wellbeing.

AM Cofactor

Vitamin C

Acerola cherry extract
What it is:

A water-soluble vitamin, here from whole acerola cherry.

Why it’s in ThyroBase:

Whole-food source with bioflavonoid cofactors intact. Supports absorption of the naturally occurring iron in the AM base.

AM Foundation

Plant Protein Matrix

24.9 g · four plant sources
What it is:

A plant protein blend from four sources.

Why it’s in ThyroBase:

Yellow pea, brown rice, faba bean, pumpkin seed. Soy-free, complete amino acid profile.

Nutrients chosen for the evening half of the day. No added caffeine. No melatonin. No sedation.

Chocolate · Cinnamon
PM Evening

Magnesium

Magnesium citrate
What it is:

An essential mineral.

Why it’s in ThyroBase:

The most documented mineral for sleep onset and quality (Abbasi, 2012, RCT). Citrate form, well-absorbed.

PM Evening

Glycine

The FSANZ permitted maximum
What it is:

An amino acid.

Why it’s in ThyroBase:

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.

PM Evening

Chamomile

Chamomile flower powder
What it is:

A traditional evening botanical.

Why it’s in ThyroBase:

Apigenin is the chamomile compound most studied for its calming role. Many thyroid people describe a "wired but tired" pattern at night.

PM Evening

Passionflower + Grapeseed

Botanical extracts
What it is:

Two botanical extracts.

Why it’s in ThyroBase:

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.

PM Evening

Probiotics

A real probiotic blend, in every evening serve
What it is:

Live cultures, included in every evening serve.

Why it’s in ThyroBase:

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.

PM Evening

Prebiotic Fibre

Acacia gum + psyllium husk
What it is:

Two soluble plant fibres.

Why it’s in ThyroBase:

Feeds the live strains overnight and supports gut barrier function, which matters for hormone conversion.

The foundation

The flavouring, sweetening, and finishing ingredients are held to the same standard as the actives. Whole-food sources. No artificial sweeteners. No flavour chemicals.

PM Flavour base

The seed of the cacao fruit, fermented and ground.

Why it’s in ThyroBase:

The heart of PM cocoa flavour. Naturally rich in magnesium and antioxidant polyphenols.

PM Flavour

What it is:

Whole ground vanilla bean.

Why it’s in ThyroBase:

Real vanilla bean, not synthetic flavouring. Adds depth and warmth to PM.

PM Warm spice

Cinnamon

Whole-spice
What it is:

A whole warming spice.

Why it’s in ThyroBase:

Adds the warm-spice signature to PM. A traditional warming spice that makes the chocolate flavour read as dessert, not medicine.

Nutmeg

Whole-spice
What it is:

A whole warming spice.

Why it’s in ThyroBase:

A pinch in PM for warmth and depth.

Natural sweetness

Lucuma

Low-glycemic Peruvian fruit

Named, not hidden: kale, spinach and broccoli sprout at culinary levels. Naturally rich in chlorophyll and trace micronutrients.

Algal nutrition

Spirulina

Freshwater blue-green algae
What it is:

A freshwater blue-green algae.

Why it’s in ThyroBase:

Algal protein and pigments. Iron-rich. Quiet plant nutrition in the AM blend.

What's missing matters

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.

Added iodine
Unnecessary if you're on thyroid hormone medication. Can interfere with treatment and is documented to trigger or worsen autoimmune thyroid conditions in susceptible people.
Kelp
High iodine content by another name. Contraindicated for most people on thyroid medication.
Soy isoflavones
Documented to impair thyroid medication absorption and may interfere with hormone signalling.
Added goitrogens
No goitrogenic agents are added to either formula: no raw brassica concentrates, no soy, no millet. The greens blend includes kale (1.2 g) and broccoli sprout (0.25 g) per serve, genuinely culinary amounts, a fraction of a side salad. If you are highly goitrogen-sensitive, check with your doctor.
Glandular extracts
Unregulated hormone content from animal sources. Quality control is unreliable.
Caffeine and stimulants
Caffeine reduces thyroid medication absorption by 25 to 50% when taken too close to a dose. Guarana and synthetic stimulants amplify the wired-but-tired pattern.
Melatonin
We support the underlying physiology of sleep (glycine, magnesium, chamomile, passionflower) rather than override it with a hormone signal.
Synthetic fillers and gums
Xanthan, guar, carrageenan. None of them earn their place in a daily ritual.
Artificial sweeteners
Sucralose, aspartame, acesulfame-K. We use the natural sweetness of cocoa, vanilla, lucuma, and monk fruit.
