Liquid Iodine 20% Drops — Maximum-Strength Iodine Supplement in Purified Water

20% Liquid Iodine from Lugols Originals is the highest-concentration formula in the Liquid Iodine lineup: molecular iodine and potassium iodide in purified water at ten times the per-drop yield of the 2% formula and twice that of the 10%. At 20%, each drop delivers the maximum iodine yield available in this lineup — very few drops are needed per serving, making precise measurement essential. This is the formula for experienced liquid iodine users who know their serving size exactly, want the most concentrated format available, and value the storage efficiency of a high-yield, shelf-stable amber glass bottle. Manufactured in the U.S.A.

What Is Liquid Iodine?

Liquid iodine supplements deliver iodine in a water-based solution for easy, drop-based dosing. This formula uses molecular iodine (I₂) and potassium iodide (KI) in purified water — a combination used in liquid iodine supplementation for nearly two centuries. Iodine is an essential trace mineral; diets low in iodized salt or seafood may contain limited iodine from food sources alone. Lugols Originals’ Liquid Iodine is manufactured in the U.S.A. using high-purity ingredients with no fillers or artificial additives.

What makes the 20% strength distinct:

✔ Concentration: 20% — the highest in the lineup; 10x the iodine per drop vs. the 2% formula; 2x vs. the 10% formula
✔ Formula: Molecular iodine (I₂) + potassium iodide (KI) in purified water
✔ Additives: None — three ingredients, nothing else
✔ Serving efficiency: Maximum iodine yield per drop in the lineup — very few drops per serving; precise measurement is essential
✔ Storage: Shelf-stable in amber glass — the most compact, long-lasting iodine supply option in the lineup
✔ Supply: One 2oz amber glass dropper bottle = approximately 30-day supply at standard serving
✔ Packaging: Amber glass dropper bottle — no plastic contact with the solution
✔ Origin: Made in the U.S.A. by Lugols Originals

How to Use

Add the recommended number of drops to a glass of water or juice. Use the included glass dropper for consistent, precise measurement. At 20%, each drop delivers the highest iodine yield in the lineup — use care when measuring, start with fewer drops than you used at any lower concentration, and follow the serving guidance on the label exactly. Consult a qualified healthcare provider before use if you are pregnant, nursing, taking prescription medications, or have a known sensitivity to iodine.

Frequently Asked Questions

Is 20% liquid iodine appropriate for beginners?

No. 20% is the highest-concentration formula in the lineup and is intended for users who have already established a routine with liquid iodine at a lower strength and know their preferred serving size precisely. If you are new to liquid iodine, start with 2% or 5%. If you have been directed to 20% specifically by a practitioner, follow that guidance.

Why do preparedness buyers choose 20% over lower concentrations?

At 20%, you need very few drops per serving — the highest iodine yield per drop in the lineup. This means a given bottle volume goes further in terms of serving count than any lower-concentration formula. Combined with the shelf-stable amber glass packaging, the 20% formula is the most storage-efficient option in the lineup for users building a long-term iodine supply. Store in a cool, dark location away from direct light and heat.

What are the ingredients in 20% liquid iodine?

Three ingredients: molecular iodine (I₂), potassium iodide (KI), and purified water. No fillers, no artificial additives. Manufactured in the U.S.A. by Lugols Originals.

How does 20% liquid iodine compare to the rest of the lineup?

The 20% formula delivers twice the iodine per drop of the 10%, four times that of the 5%, and ten times that of the 2%. It requires the fewest drops per serving of any formula in the lineup. See our full concentration range: 2%, 5%, 10%.
