Iodine is an essential mineral your body uses to support normal thyroid hormone production, which helps regulate metabolism and energy. Kelp is a natural source of iodine, but amounts can vary, so the most important step is checking the iodine (mcg) per serving on the label. If you have thyroid concerns or are pregnant/breastfeeding, get personalised advice first.

How to choose an iodine (kelp) supplement

• Know your goal: Are you topping up iodine intake, or looking for a broader daily routine that includes iodine/kelp as part of a multi? Choose accordingly.
• Check the iodine amount (mcg): Compare the “iodine per serving” across products and follow label directions—more isn’t automatically better.
• Prefer consistent, clearly labelled formulas: Kelp can vary naturally, so look for products that clearly state iodine content per dose.
• Consider your routine: If you want an “all-in-one” approach, a senior multi that includes iodine (from kelp) may fit better than adding multiple separate products.
• Safety first: If you have thyroid conditions, take thyroid medication, or are pregnant/breastfeeding, ask a pharmacist or clinician before starting or changing iodine intake.

FAQs

What are iodine supplements used for?

Iodine supplements are used to support adequate iodine intake, which helps your body make thyroid hormones. Thyroid hormones support normal metabolism and energy regulation.

What are the benefits of taking iodine with kelp?

Iodine is the key nutrient; kelp is one natural source of it. The practical benefit is a convenient way to include iodine in a daily supplement routine—just make sure the label clearly lists the iodine (mcg) per serve.

How much iodine should I take?

Follow the label directions and avoid stacking multiple iodine sources unless advised. If you’re unsure what’s appropriate for you, a pharmacist or clinician can help you factor in diet, supplements, and individual needs.

What are signs of low iodine?

Low iodine intake can contribute to thyroid-related symptoms over time, but symptoms are not specific and can overlap with many other issues. If you suspect low iodine, it’s best to discuss next steps with a healthcare professional rather than self-diagnosing.

Is there any downside to taking iodine supplements?

Yes—too much iodine can be unhelpful for some people, especially if you’re sensitive to iodine or have underlying thyroid concerns. If symptoms change after starting, stop and seek advice.

Who should avoid taking iodine or kelp supplements?

If you have a thyroid condition, take thyroid medication, or have been advised to limit iodine, get personalised guidance first. This is especially important if you’re considering higher-dose iodine or combining multiple products that may contain iodine.

Can I take iodine/kelp supplements during pregnancy or breastfeeding?

Sometimes iodine support is recommended during pregnancy and breastfeeding, but the right approach varies by person. Speak with your midwife, GP, or pharmacist before starting or changing iodine intake.

What’s the difference between an iodine/kelp ingredient collection and a single-ingredient iodine product?

An ingredient collection groups products that include iodine/kelp as part of a broader formula. A single-ingredient product is designed mainly to provide iodine—so always check the label to confirm what you’re taking.
