Lugol's Solution 5% Iodine Drops — Higher Yield, Same Two-Ingredient Formula

5% Lugol's Solution is a step-up concentration of the original 1829 formula: 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 5%, each drop delivers 2.5 times the iodine of our 2% formula — more iodine per drop, fewer drops per serving, same clean-label two-ingredient formulation.

Why Lugol's Solution?

Lugol's Solution is a two-ingredient liquid iodine source with no binders, capsule fillers, or synthetic additives. Diets low in iodized salt, seafood, or dairy may contain limited iodine, and liquid supplementation is a straightforward way to add a traceable, measurable iodine source to a wellness routine. 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 5% strength distinct:

• ✔ Concentration: 5% — delivers 2.5x the iodine per drop compared to our 2% formula
• ✔ Formula: Molecular iodine (I₂) + potassium iodide (KI) in purified water — two ingredients, nothing else
• ✔ Serving: Fewer drops needed per serving compared to lower concentrations
• ✔ 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 for long-term storage
• ✔ 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

• Users who have already tried 2% Lugol’s and want a higher per-drop yield without changing their drop count
• Functional health followers directed to 5% specifically by a practitioner or community and comparison-shopping on purity and sourcing
• Clean-label supplement stackers who want a higher-yield iodine source with the same minimal-ingredient formulation
• Plant-based and low-salt dieters looking for a more concentrated liquid iodine option to cover potential dietary gaps efficiently
• Emergency preparedness buyers who want a higher-concentration option for stockpiling — more iodine per bottle, same shelf-stable glass packaging

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. Because 5% delivers more iodine per drop than lower concentrations, start with fewer drops than you might use with a 2% formula and adjust over time. 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

What is the difference between 5% and 2% Lugol’s Solution?

The 5% formula delivers 2.5 times the iodine per drop compared to our 2% formula. The ingredient list is identical — molecular iodine (I₂), potassium iodide (KI), purified water — only the concentration differs. If you were taking 6 drops of 2%, you would take fewer drops of 5% to reach a comparable serving. The 2% is the recommended starting point for new users; 5% is the natural next step for those who want a higher yield per drop.

What is the difference between 5% Lugol’s Solution and 5% Nascent Iodine?

Lugol’s Solution contains two iodine compounds — molecular iodine (I₂) and potassium iodide (KI) — in the classic 1829 ratio. Nascent Iodine is a single-compound, atomized ionic form of iodine in a carrier liquid. They are chemically distinct products with different compositions. See our Nascent Iodine collection for a full comparison.

How long does one 2oz bottle last?

At a standard serving, one 2oz bottle provides approximately a 30-day supply. Because 5% delivers more iodine per drop than lower concentrations, you will typically use fewer drops per serving, which affects total bottle duration. Exact duration depends on your daily serving size.

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 — a key consideration for emergency preparedness buyers or anyone purchasing in quantity for long-term storage.
