Lugol's Solution 2% Iodine Drops — Classic Formula, Entry-Level Strength

2% Lugol's Solution is the lowest-concentration version of the original 1829 formula: molecular iodine (I₂) and potassium iodide (KI) dissolved in purified water, with nothing else added. It is not Nascent Iodine (an atomized ionic form) and not a general liquid iodine blend — it is the specific two-compound Lugol's preparation that has been used as a dietary iodine source for nearly 200 years. At 2%, each drop delivers the smallest per-drop dose in the Lugols Originals lineup, making it the right starting point for holistic health consumers who are new to liquid iodine and want full control over their intake from day one.

Why Lugol's Solution?

Iodine is an essential mineral the body cannot produce — it must come from food or supplementation. Diets low in iodized salt, seafood, or dairy may contain limited iodine. Lugol's Solution is a clean-label option: two ingredients (molecular iodine and potassium iodide) in purified water, no binders, no capsule fillers, no synthetic additives. Every bottle is manufactured in the U.S.A. by Lugols Originals using high-purity ingredients, in a facility dedicated to iodine production. If traceability and ingredient simplicity matter to your wellness routine, this is the formulation to start with.

What makes the 2% strength distinct:

• ✔ Concentration: 2% — the gentlest Lugol's formula in the Lugols Originals lineup, ideal for building a baseline
• ✔ Formula: Molecular iodine (I₂) + potassium iodide (KI) in purified water — two ingredients, nothing else
• ✔ Serving: 1–6 drops per day in water or juice; start low and adjust to your preference
• ✔ Supply: One 2oz glass dropper bottle = approximately 30-day supply at standard serving
• ✔ Packaging: Amber glass dropper bottle — no plastic contact with the solution, supports long-term storage stability
• ✔ 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

• Holistic and clean-label supplement users who have already optimized their diet and want a traceable, minimal-ingredient iodine source to fill a potential dietary gap — especially those avoiding processed foods or iodized salt
• First-time liquid iodine users who want the smallest available dose and the ability to titrate up gradually on their own schedule
• Plant-based and whole-food dieters whose iodine sources from food may be limited
• Functional health followers who were directed to Lugol’s Solution specifically and are looking for a verified, pure-sourced 2% option
• Long-term Lugol’s users who have settled on 2% as their preferred daily concentration

How to Use

Add 1–6 drops to a glass of water, juice, or another beverage of your choice. Use the included glass dropper for consistent, precise measurement. Begin with a lower number of drops 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 2% Lugol’s Solution and Nascent Iodine?

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

Why start at 2% instead of a higher concentration?

The 2% formula delivers the smallest per-drop dose in our lineup, giving you the most granular control when establishing your routine. Higher concentrations (5%, 10%, 15%, 20%) deliver more iodine per drop and are typically chosen by experienced users, those directed to a specific strength by a practitioner, or buyers purchasing for long-term storage. If you are new to Lugol’s, 2% is the recommended entry point.

How long does one 2oz bottle last?

At a standard serving of 1–6 drops per day, one 2oz bottle provides approximately a 30-day supply. 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 specifically chosen over plastic to preserve solution integrity over time — an important consideration for anyone purchasing for emergency preparedness or long-term storage.
