Lugol's Solution 10% Iodine Drops — 4oz Bottle, ~60-Day Supply

This is the 4oz format of our 10% Lugol's Solution: the same original 1829 formula — molecular iodine (I₂) and potassium iodide (KI) in purified water, nothing else — in a larger bottle that delivers approximately twice the supply of our standard 2oz size. At 10%, each drop delivers five times the iodine of our 2% formula. The 4oz format is for experienced users who have established a 10% routine and want a two-month supply without monthly reorders.

Why the 4oz Format?

The 4oz bottle contains the same two-ingredient Lugol's Solution as our 2oz — molecular iodine and potassium iodide in purified water, with no binders, fillers, or synthetic additives. At a standard serving, one 4oz bottle provides approximately 60 days of use. For users with an established 10% routine, the larger format means uninterrupted supply and fewer reorders. Every bottle is manufactured in the U.S.A. by Lugols Originals using high-purity ingredients.

What makes the 4oz format distinct:

✔ Size: 4oz — double the volume of our standard 2oz bottle
✔ Supply: Approximately 60-day supply at standard serving
✔ Concentration: 10% — 5x the iodine per drop vs. our 2% formula; 2x vs. our 5%
✔ Formula: Molecular iodine (I₂) + potassium iodide (KI) in purified water — two ingredients, nothing else
✔ Packaging: Amber glass dropper bottle — no plastic contact with the solution
✔ Formulated without alcohol for a milder taste
✔ Origin: Made in the U.S.A. by one of the world’s largest dedicated iodine manufacturers

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 10%, each drop is significantly more concentrated than lower-strength formulas — start with fewer drops than you used at a lower concentration and adjust gradually. 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 the formula the same as the 2oz version?

Yes — identical formula, larger bottle. The 4oz contains the same 10% Lugol's Solution: molecular iodine (I₂) and potassium iodide (KI) in purified water. The only difference is volume and supply duration.

How long does the 4oz bottle last?

At a standard serving, one 4oz bottle provides approximately a 60-day supply. Because 10% delivers more iodine per drop than lower concentrations, you will typically use fewer drops per serving. Exact duration depends on your daily serving size.

Should I start with the 4oz or the 2oz?

If you are new to 10% Lugol's Solution, start with the 2oz bottle to establish your preferred serving size before purchasing the larger format. The 4oz is best suited to users who already know how many drops they use daily.

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 preserves solution integrity over time.
