Lugol's Solution 15% Iodine Drops — 7.5x the Iodine of Our 2% Formula

15% Lugol's Solution is one of the highest-concentration versions of the original 1829 formula available from Lugols Originals: molecular iodine (I₂) and potassium iodide (KI) in purified water, with nothing else added. It is not Nascent Iodine and not a general liquid iodine blend. At 15%, each drop delivers 7.5 times the iodine of our 2% formula, three times the iodine of our 5% formula, and 50% more per drop than our 10% formula. This concentration is intended for experienced users who know exactly what strength they are looking for and require the highest per-drop yield in a standard 2oz dropper bottle.

Why Lugol's Solution?

Lugol's Solution is a two-ingredient liquid iodine source — molecular iodine and potassium iodide in purified water — with no binders, capsule fillers, or synthetic additives. Diets low in iodized salt, seafood, or dairy may contain limited iodine. At 15%, the formula delivers a highly concentrated dose per drop, making it suited to users who have established a routine at lower concentrations and are sourcing a specific high-yield strength. Every bottle is manufactured in the U.S.A. by Lugols Originals using high-purity ingredients, in a facility dedicated to iodine production.

What makes the 15% strength distinct:

• ✔ Concentration: 15% — 7.5x the iodine per drop vs. our 2% formula; 3x vs. our 5%; 50% more per drop than our 10%
• ✔ Formula: Molecular iodine (I₂) + potassium iodide (KI) in purified water — two ingredients, nothing else
• ✔ Serving: Very few drops needed per serving — precise dropper dosing is essential at this concentration
• ✔ Supply: One 2oz glass dropper bottle = approximately 30-day supply at standard serving
• ✔ Packaging: Amber glass dropper bottle — no plastic contact with the solution, preserves solution integrity over time
• ✔ Formulated without alcohol for a milder taste
• ✔ Origin: Made in the U.S.A. by one of the world’s largest dedicated iodine manufacturers

Who This Is For

• Experienced Lugol’s users who have worked through lower concentrations and are sourcing a specific high-yield strength for their established routine

• Users who require the fewest drops per serving and have determined that lower concentrations are impractical for their daily routine
• Bulk and long-term storage buyers who want maximum iodine density per bottle before stepping to our 20% formula
• Buyers purchasing in quantity who want the highest-concentration 2oz option before stepping to our 20% formula

How to Use

Add the recommended number of drops to a glass of water, juice, or another beverage. Use the included glass dropper for consistent, precise measurement. At 15%, each drop is highly concentrated — use care when measuring and start with fewer drops than you used at a lower concentration. 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

How does 15% Lugol’s Solution compare to 10%?

The 15% formula delivers 50% more iodine per drop than our 10% formula, and 7.5 times the iodine per drop compared to our 2% formula. The ingredient list is identical across all concentrations — molecular iodine (I₂), potassium iodide (KI), purified water. If stepping up from 10%, reduce your drop count by approximately one-third to start at a comparable serving.

Is 15% Lugol’s Solution appropriate for new users?

No. 15% is a high-yield concentration intended only for experienced users who are already familiar with liquid iodine supplementation, drop-based dosing, and their own established routine. If you are new to Lugol’s Solution, start with our 2% formula and work up gradually.

What is the difference between 15% and 20% Lugol’s Solution?

Our 20% formula delivers one-third more iodine per drop than the 15% formula and is the highest concentration in the Lugols Originals lineup. Both use the identical two-ingredient formulation. The 15% is the appropriate choice for users who want a near-maximum concentration without the full yield of 20%. See our 20% Lugol’s Solution for a full comparison.

Is this product shelf-stable for long-term storage?

Lugol’s Solution is chemically stable when stored in a cool, dark location away from direct light and heat. The amber glass dropper bottle is chosen specifically to preserve solution integrity over time.
