Pure Encapsulations Iodine & Tyrosine is a food supplement combining iodine (as potassium iodide) with free-form L-tyrosine in a single vegetarian capsule. The pack contains 60 capsules, giving a one-a-day source of iodine to support normal thyroid function alongside the amino acid tyrosine.

Key Features

• Iodine at 150% NRV: Each capsule provides 225 µg of iodine (as potassium iodide), 150% of the Nutrient Reference Value. Iodine contributes to normal production of thyroid hormones, normal thyroid function, normal energy-yielding metabolism, and normal function of the nervous system and cognitive function.
• Potassium iodide as the iodine source: potassium iodide gives a consistent, measurable amount of iodine in every capsule, unlike seaweed or kelp, where natural iodine content can vary considerably between batches.
• 500 mg free-form L-tyrosine: tyrosine is an amino acid the body uses, alongside iodine, as a building block for thyroid hormones.
• Free from common allergens and unnecessary additives: formulated without gluten, wheat, egg, peanuts, soya, dairy or GMO ingredients, and without unnecessary binders, fillers or artificial colours, flavours or sweeteners.
• Vegan and vegetarian capsule: the capsule shell is made from hydroxypropyl methylcellulose (HPMC) rather than gelatine, so the whole product is suitable for vegans and vegetarians.
• Simple once-daily dose: one capsule with a meal, making it straightforward to fit into a daily routine.

What is Iodine & Tyrosine used for?

This supplement provides a source of iodine and the amino acid tyrosine in one capsule. Iodine contributes to the normal production of thyroid hormones and normal thyroid function, normal energy-yielding metabolism, and the normal function of the nervous system and cognitive function. Tyrosine is an amino acid the body uses, together with iodine, as a building block for thyroid hormones.

How many capsules should I take, and can I take more than one a day?

The guidance for this product is 1 capsule daily, with a meal, or as directed by a healthcare professional. Do not exceed this stated dose unless a healthcare professional advises otherwise, even if other iodine products you've seen suggest a different schedule.

Why does this supplement use potassium iodide rather than seaweed or kelp as its iodine source?

Potassium iodide provides a consistent, precisely measurable amount of iodine in every capsule. Seaweed and kelp are natural sources of iodine, but their iodine content can vary considerably from batch to batch, making the exact dose less predictable.

Is this supplement suitable for vegans and people with allergies?

Yes. The capsule shell is made from hydroxypropyl methylcellulose (HPMC) rather than gelatine, so the product is suitable for vegans and vegetarians. It is also formulated without gluten, wheat, egg, peanuts, soya, dairy or GMO ingredients, and without unnecessary binders, fillers or artificial additives.
