Aegis™ Potassium Iodide Tablets 130mg — 120 Count | FDA-Compliant Thyroid Protection "I'd rather have it and not need it, than need it and not have it." This timeline has gotten unpredictable. Nuclear power plants, geopolitical instability, things that used to feel distant don't anymore. You're not being dramatic — you're being smart. Potassium Iodide (KI) is the same thyroid-blocking compound stockpiled by governments and distributed to families living near nuclear facilities. When radioactive iodine enters the environment, your thyroid is the first organ at risk — especially for your kids. KI works by saturating your thyroid with stable, non-radioactive iodine so there's no room left for the dangerous kind. One bottle. 120 tablets. Enough to protect your whole family when it matters most. FDA-recognized. Clinically backed. Built for the prepared. This product is intended for emergency preparedness use. Follow guidance from public health officials during a radiation emergency.
