🍏 9 Nutrients Your Thyroid Can’t Live Without
When it comes to thyroid health, there are nine key nutrients that can make or break your energy, metabolism, and antibody levels.
And here’s the thing:
I see so many people chasing medications, diets, and detoxes… but missing the simple foundation of thyroid-specific nutrition.
Here’s what you need to know ⬇️
𝟭. 𝗦𝗲𝗹𝗲𝗻𝗶𝘂𝗺
Supports T4 → T3 conversion (the active thyroid hormone)
Reduces thyroid antibodies (TPO, TG)
Often paired with myo-inositol in research for even better results
1 - 3 Brazil nuts per day or low-dose supplement under guidance
𝟮. 𝗜𝗼𝗱𝗶𝗻𝗲
Yes, your thyroid needs it, but too much can trigger flares if antibodies are high
Start only after selenium and iron are adequate
Seaweed, eggs, seafood = food-first approach
𝟯. 𝗜𝗿𝗼𝗻
Essential for TPO (the enzyme that builds thyroid hormone)
Low ferritin = fatigue, hair loss, brain fog
Aim for ferritin 70–100 µg/L if struggling with fatigue or hair loss
𝟰. 𝗭𝗶𝗻𝗰
Needed for TSH signaling + immune balance
Works closely with selenium + vitamin A for thyroid hormone production
Oysters, beef, eggs = top sources
𝟱. 𝗩𝗶𝘁𝗮𝗺𝗶𝗻 𝗗
Key immune modulator - lowers antibodies, supports mood + energy
MinimumTarget: 30–50 ng/mL (120–150 nmol/L) for thyroid autoimmunity
𝟲. 𝗩𝗶𝘁𝗮𝗺𝗶𝗻 𝗔
Supports thyroid receptor signaling + tissue repair
Found in liver, eggs, dairy (or beta-carotene from colorful veggies)
𝟳. 𝗧𝘆𝗿𝗼𝘀𝗶𝗻𝗲
Amino acid building block for thyroid hormones
Found in animal proteins, dairy, legumes
𝟴. 𝗢𝗺𝗲𝗴𝗮-𝟯𝘀
Anti-inflammatory, calming for the immune system
Sardines, salmon, mackerel = excellent choices
𝟵. 𝗩𝗶𝘁𝗮𝗺𝗶𝗻 𝗘
Protects thyroid tissue from oxidative stress
Found in almonds, sunflower seeds, avocado
Here’s the key:
You don’t need to take everything all at once or in high doses.
What you do need is a food-first strategy, targeted supplementation, and labs checked every 8 - 12 weeks so you know what’s working.
