COMMON QUESTIONS
Everything about Liquid Iodine
Is Liquid Iodine safe to take every day?
Many people use iodine as part of a daily routine, but the right amount is individual. Follow the serving guidance on the label and talk with a healthcare provider before starting — especially if you take thyroid medication or have a known sensitivity to iodine.
What's the difference between the strengths?
The formula is the same; only the concentration changes. A higher percentage means more iodine per drop — for example, 5% has 2.5x the iodine per drop of our 2% formula. Each strength is its own product listing.
How is this different from your Lugol's Solution and Nascent Iodine?
Liquid Iodine and Lugol's Solution both use molecular iodine and potassium iodide in purified water. Nascent Iodine is potassium iodide in an ionic form, in purified water and food-grade vegetable glycerin, with no alcohol. What is Lugol's Solution? →
Can I take this while pregnant or nursing?
Talk to your healthcare provider before using any iodine supplement while pregnant or nursing.
How should I store an opened bottle?
Keep it capped and upright in a cool, dark place, away from direct light and heat. The amber glass bottle helps protect the solution from light.
What if I miss a dose?
Pick up with your usual routine. If you're unsure how to adjust, ask your healthcare provider.
