Lugol's Iodine Solution Liquid | 5% | 30 ml | Sun Dex

Sun Dex Lugol's Iodine Solution 5% is an aqueous iodine solution in a 30 ml dropper bottle, used as a source of the iodine the thyroid gland needs to produce its hormones. Lugol's solution is a pharmaceutical form known since the nineteenth century, and it is sought by anyone wanting a liquid iodine source that can be dissolved in water rather than fixed-dose tablets. The 5% strength is the figure stated on the bottle and is what distinguishes this solution from weaker concentrations.

What Is Lugol's Solution?

Lugol's Solution is an aqueous solution combining elemental Iodine with Potassium Iodide, named after the French physician who first described it. Elemental iodine does not dissolve in water on its own, so potassium iodide is added; it binds the iodine to form a soluble triiodide ion. Iodine itself is an essential trace element the body cannot make, and its main dietary sources are sea fish, seaweed and iodised salt.

Benefits of Iodine

• Supports the thyroid gland: Iodine is the core atomic component in the thyroid hormones T3 and T4.
• Supports energy metabolism: Thyroid hormones regulate the basal metabolic rate in most cells of the body.
• Supports body temperature regulation: Iodine-dependent thyroid activity is tied to heat generation within tissues.
• Supports neurological development: Iodine is considered an essential element during early stages of nervous system development.
• A liquid form with flexible dosing: Lugol's solution with a dropper allows the amount to be set precisely, unlike a fixed-dose tablet.

How It Works Inside the Body

Once absorbed, iodine is taken up from the blood by the sodium-iodide symporter (NIS) on the membrane of thyroid cells, an active transporter that drives iodine into the cell against the concentration gradient. Inside the cell, iodine is oxidised by thyroid peroxidase and then binds the tyrosine rings in thyroglobulin protein, and the coupling of two iodinated rings yields the hormone thyroxine. The presence of potassium iodide in Lugol's solution keeps the iodine dissolved and ready for absorption rather than precipitating.

What Sets This Formula Apart

Sun Dex Lugol's solution at 5% comes in a dropper bottle that makes the dosing unit a drop rather than a tablet, which allows a fine gradation that is hard to achieve with solid forms. The liquid form dissolves directly in water, so it needs no disintegration step in the stomach, and a 30 ml size lasts a long time because the unit of use is a drop. Lugol's solution differs from alcoholic iodine tincture, which is intended for external use, in that its vehicle is aqueous.

Who Is It For?

• Anyone whose diet sits far from fish and seaweed.
• Anyone who prefers liquid forms whose dose is set by the drop.
• Anyone tracking thyroid function with their doctor who wants an iodine source of known strength.
• Anyone looking for Lugol's solution with an aqueous rather than alcoholic vehicle.

How to Use

Lugol's solution is added to a glass of water and drunk, preferably in the morning. Start with the smallest possible number of drops; setting the daily dose and the duration of use should be done under a doctor's supervision, because iodine is a trace element with a narrow window between deficiency and excess. Store the solution in a cool, dry place away from direct light.

Frequently Asked Questions

What is the difference between Lugol's solution and iodine tincture?

Lugol's solution has an aqueous vehicle and combines elemental iodine with potassium iodide. Iodine tincture has an alcoholic vehicle and is intended for external use on the skin.

Why does Lugol's solution contain potassium iodide?

Elemental iodine is poorly soluble in water, and potassium iodide binds to it forming a soluble triiodide ion. That is the basis of the Lugol formulation as first described.

Is Lugol's solution taken neat without dilution?

Lugol's solution is added to a glass of water and is not placed directly on the tongue, because concentrated iodine irritates mucous membranes. Dilution in water is an essential step in using it.
