Lugol's Solution of Iodine Liquid | 2% | 60 ml | J.Crow's

J.Crow's Lugol's Solution of Iodine 2% is an aqueous solution in a 60 ml dropper bottle, the classic pharmaceutical preparation known by Lugol's name. What separates this format from iodine capsules is that the amount is set drop by drop, allowing a fine gradation no pre-moulded dose can offer, and that is precisely why the preparation has stayed in use under medical supervision. It suits anyone whose physician sets the amount for them, and anyone who finds capsules and tablets difficult to swallow.

What is Lugol's solution?

Lugol's Solution of Iodine is an aqueous solution combining molecular iodine with potassium iodide in a single bottle, and it is one of the oldest pharmaceutical formulas to have kept its essential composition without substantive change. The reason for combining the two is purely chemical rather than promotional: molecular iodine is poorly soluble in water, but it dissolves once bound to an iodide ion, forming the soluble triiodide ion. Describing the strength as 2% places this particular solution among the various Lugol's concentrations.

Active ingredients

• Molecular iodine: the elemental form of iodine, and the form that is poorly soluble in water on its own.
• Potassium iodide: a salt supplying the iodide ion that raises molecular iodine's solubility and holds it stable in the aqueous medium.
• Purified water: the carrier medium in which the complete formula dissolves without settling out.

Benefits of iodine

• An irreplaceable raw material: iodine is the only element the two thyroid hormones are built from, and nothing else substitutes for it in that pathway.
• Energy expenditure control: the thyroid hormones built on iodine raise the rate of oxygen consumption inside the cell.
• Presence beyond the thyroid: iodine also concentrates in the salivary glands and stomach lining through the same transporter.
• Metabolic steadiness: a regular iodine supply is associated with a stable overall metabolic rate.
• A gradable amount: the liquid format allows the amount to be set drop by drop as a physician directs.

How Lugol's solution works in the body

Lugol's solution reaches the digestive tract already dissolved and ready, waiting on no capsule shell to break open and no compressed tablet to disintegrate. After absorption, molecular iodine is reduced to iodide in the biological environment and joins the iodide arriving from potassium iodide, so the two routes become one inside the body. From there the sodium-iodide symporter embedded in the thyroid cell membrane captures the ion and draws it into the gland for hormone synthesis, while the surplus is cleared through the kidney.

What sets this preparation apart

J.Crow's Lugol's Solution of Iodine brings both iodine species together at 2% strength in a 60 ml dropper bottle. The difference between a liquid solution and a capsule shows up in two places: the amount is flexible and set drop by drop rather than locked into a fixed unit, and the solution blends straight into water so absorption begins with no disintegration step first. Knowing the concentration is a precondition for using this preparation, because concentration is what determines how much iodine a single drop carries. The bottle is opaque with an integrated dropper because iodine is affected by direct light.

Who is this product for?

• Anyone whose physician sets the amount drop by drop.
• Anyone who prefers a gradable liquid to a fixed dose.
• Anyone who finds capsules and tablets hard to swallow.
• Anyone seeking the traditional pharmaceutical preparation known by its historic name.

How to use

Use Lugol's Solution of Iodine only at the amount a physician determines, because iodine is measured in very fine amounts and more of it does not mean greater support. Always dilute the drops in a glass of water or juice, and never place them undiluted on the tongue or on mucous membranes. Keep the bottle tightly closed in a cool dark place out of the reach of children, and avoid contact with fabrics and light-coloured surfaces, since the solution leaves a stain.

Frequently asked questions

Why does Lugol's solution contain two forms of iodine?

Lugol's solution combines molecular iodine and potassium iodide for a chemical reason: molecular iodine is poorly soluble in water, and binding it to an iodide ion forms the soluble triiodide ion. Without that pairing, a stable aqueous iodine solution could not be prepared at all.

What does 2% mean in Lugol's solution?

The 2% figure describes the proportion of iodine within the solution, and Lugol's solutions are prepared at various strengths whose single drops differ substantially from one another. Knowing the strength is therefore a precondition before any use.

How should iodine solution be stored?

Iodine solution is kept in its opaque bottle, tightly closed, in a cool place away from direct light, because iodine is affected by light and heat. It should be kept out of the reach of children at all times.

Cautions
