Ingredients & Dosage
2% Lugol's Solution Iodine Drops — Entry-Level Formula, 2oz bottle, ~30-day supply

Why Lugol's Solution?
Lugol's Solution is a two-ingredient liquid iodine source with no binders, capsule fillers, or synthetic additives: molecular iodine and potassium iodide in purified water. Iodine is an essential trace mineral your body uses for normal thyroid hormone production.

- ✔ Packaging: Amber glass dropper bottle — no plastic contact with the solution

The original formula
Molecular iodine and potassium iodide in the same 1829 ratio, at a concentration you choose.
Made in the USA
Formulated and bottled domestically, in an amber glass dropper bottle that protects the solution from light.
Dosing you control
Drop-by-drop dosing, adjustable in a way a fixed-dose tablet isn't — diluted in water or juice.
WHY LUGOL'S SOLUTION
Lugol's Solution is a liquid iodine formula first documented in 1829, combining molecular iodine (I₂) with potassium iodide in a stable aqueous solution. We offer it at six concentrations — 2% through 20%, each its own product listing — so you can pick the strength that matches your routine with your provider, then choose the pack size that fits how you stock up. Every bottle is formulated and packaged in the USA and shipped in light-protective amber glass.
01
Original 1829 ratio
The same molecular-iodine-to-iodide ratio used in the original formulation, not a synthetic substitute.
02
Six concentrations
From a gentle 2% entry strength to a maximum 20%, so dosing can be tailored with your provider.
03
Amber glass, light-protected
Iodine solutions degrade in light — every bottle ships in amber glass with a glass dropper.
04
Backed by the Iodine Journal
Our editorial library covers dosing, formulation, and the actual evidence — no disease claims, just the facts.

COMMON QUESTIONS
Everything about Lugol's Solution
Is Lugol's Solution 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 Nascent Iodine line?
Lugol's Solution is molecular iodine plus 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 Nascent Iodine? →
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.
