What we use: Potassium Iodide²⁸

What it does:

• Makes thyroid hormones²⁸
• Controls how fast your body burns energy (metabolism)²⁸
• Regulates body temperature²⁸
• Super important for brain development²⁸

When you don't get enough:

• Goiter (your neck swells up)²⁸
• Always tired²⁸
• Gain weight easily²⁸
• Always feel cold²⁸
• Babies born to moms without enough can have serious brain problems²⁸

Why potassium iodide is best: It's the most stable form that your body can actually use.²⁸ Some companies use kelp or other "natural" sources, but those are all over the place in how much iodine they have. Potassium iodide gives exact amounts every time and absorbs at over 95%.²⁸ When it comes to your thyroid, consistency matters.
