Lugol's Solution of Iodine Liquid | 5% | 100 ml

Lugol's Iodine Solution 5% in a 100 ml bottle is an aqueous iodine solution taken by the drop in water, supporting thyroid function with a mineral the body cannot make. Iodine is a trace mineral built directly into the structure of the thyroid hormones themselves, which is why intake is tied to metabolic rate and daily activity levels. At 5%, this is the higher of the common Lugol's strengths, meaning more iodine per drop and fewer drops for the same amount.

What is Lugol's solution?

Lugol's solution is an aqueous solution combining molecular iodine and potassium iodide, named after the French physician Jean Lugol who described it in the nineteenth century. Pairing the two forms is not incidental: molecular iodine alone dissolves poorly in water, and the presence of iodide is what keeps it dissolved and stable in solution. Iodine itself is classed as an essential trace mineral the body does not produce, so all of it comes from food or supplements.

Benefits of iodine

• Thyroid function support: Iodine is built into the structure of the thyroid hormones themselves, not merely their regulation.
• Metabolic rate support: Thyroid hormones are tied to setting the pace of metabolism in the body's cells.
• Energy level support: Thyroid balance is associated with daily physical activity and tolerance for effort.
• Mental focus support: Adequate iodine is associated with mental clarity and responsiveness.
• Hair and skin support: Fast-renewing tissues are tied to thyroid hormone balance.
• Body temperature regulation support: Thyroid hormones are associated with heat production inside cells.
• Flexible dosing by the drop: A liquid form allows the amount to be adjusted drop by drop, unlike fixed tablets.

How iodine works in the body

Iodine is absorbed from the intestine as iodide and travels in the blood to the thyroid gland, where follicular cells pull it in through a dedicated carrier known as the sodium-iodide symporter, which concentrates iodide inside the gland to many times its blood level. Within the gland, thyroid peroxidase oxidises the iodide and attaches it to tyrosine rings on the thyroglobulin protein, producing hormones carrying either four or three iodine atoms depending on where binding occurs. Those hormones are then released into the blood, and the four-atom form is converted into the more active three-atom form in peripheral tissues.

What sets this strength apart

Lugol's Iodine Solution here comes at 5%, the higher of the commonly available Lugol's strengths. The practical difference between 5% and 2% is drop density, not the nature of the substance: one drop at 5% carries more iodine, so a user reaches their amount with fewer drops and the bottle lasts longer. The second advantage lies in the liquid format itself: a dropper bottle allows a gradual drop-by-drop approach that a fixed-dose tablet cannot offer. At 100 ml, the bottle is large for this category.

Who is it for?

• People living far from the coast whose diet is light on fish and sea vegetables.
• Anyone following thyroid function under regular medical supervision.
• People who prefer liquid forms over tablets and capsules.
• Anyone wanting fine control over the amount, drop by drop.
• Anyone wanting a higher strength that reduces the daily drop count.

How to use

Begin with one drop added to a glass of water daily, then adjust the amount gradually under the guidance of a qualified healthcare practitioner rather than raising it independently. Morning is the preferred time, and the solution is never taken undiluted; it is always diluted in water. It is used in limited cycles with rest periods between them rather than open-ended continuous use.

FAQ

What is the difference between Lugol's 5% and 2%?

The difference between 5% and 2% is how much iodine a single drop carries; the substance and the formulation are identical in both. That means 5% delivers a given amount in fewer drops, while 2% allows finer steps between one level and the next.

Why does Lugol's solution combine iodine with iodide?

Lugol's solution combines molecular iodine with potassium iodide because molecular iodine on its own dissolves poorly in water. The iodide raises its solubility and keeps the solution stable, and this has been the basis of the formulation since it was first described.

How should liquid iodine solution be stored?

Liquid iodine solution should be kept in a cool place away from direct light with the bottle tightly closed, since iodine is sensitive to light and heat. It should always be kept out of reach of children.

Cautions

• Not intended for pregnant or nursing women.
• Not intended for anyone under 18; keep out of reach of children.
• Consulting a physician is mandatory with any thyroid disorder or while taking thyroid medication.
• Consult a physician when taking chronic medication, especially lithium or potassium-sparing diuretics.
• Never take undiluted; for diluted internal use only, and not a substitute for a balanced diet.
