The Complete Guide to Thyroids & IodineUpdated 4 months ago

What Is Iodine?

Iodine is an essential trace mineral that the body cannot produce on its own. It must be obtained through diet or supplementation.

For over a century, iodine has been recognized as a foundational nutrient for:

Thyroid hormone production
Metabolic function
Hormonal balance
Early development
Brain health

Its essential role in development and metabolism has made iodine one of the most studied trace minerals in modern nutrition.

Why the Thyroid Needs Iodine

The thyroid gland uses iodine to produce thyroid hormones: T3 (triiodothyronine) & T4 (thyroxine).

These hormones help regulate:

Metabolism
Energy production
Body temperature
Heart rate
Mood
Cognitive function

If iodine intake is too low, the thyroid may enlarge in an attempt to compensate. This enlargement is known as goiter.

Hypothyroidism (Low Thyroid Function)

Hypothyroidism occurs when the thyroid produces insufficient hormones. Customers with low thyroid function often ask: Can iodine help? Because iodine is required for hormone production, adequate intake is important. However, dosing must be personalized.

What Customers Have Shared: We’ve had customers with thyroid conditions who, under the guidance of their doctors, incorporated daily iodine supplementation. Some doctors recommended starting very slowly — sometimes as little as one spray per day.

After approximately one month, labs were re-tested. Based on results, doctors would:

Gradually increase iodine intake
Slowly adjust medication
Continue monitoring thyroid levels

Over the course of many months (sometimes up to a year), some individuals have shared that they were able to reduce — and in some cases discontinue — their thyroid medication under medical supervision. These stories have been incredibly heartwarming. They also highlight how important it is to move slowly and carefully. Every thyroid is unique.

Hyperthyroidism (Overactive Thyroid)

Hyperthyroidism involves excessive thyroid hormone production.

Because iodine plays a role in hormone production, medical supervision is especially important in these cases. If you have hyperthyroidism:

Do not begin iodine without physician approval
Ensure proper lab monitoring
Follow your provider’s guidance closely

Hashimoto’s Thyroiditis

Hashimoto’s is an autoimmune condition affecting the thyroid.

Individuals with autoimmune thyroid conditions must work closely with a healthcare professional before introducing iodine. Lab monitoring and gradual introduction (if appropriate) are essential.

If You No Longer Have a Thyroid

If you’ve had a full thyroid removal, iodine is no longer required for thyroid hormone production. However, iodine still plays important roles in other tissues, including: Breast tissue, Skin, Brain, Gastric tissue.

These tissues continue to utilize iodine for normal cellular function. As always, consult your healthcare provider to determine what is appropriate for you.

Thyroid Medication & Iodine Consumption

⚠️ Important: If you have a thyroid condition or are taking thyroid medication, always consult your healthcare provider before supplementing with iodine. Changes to medication or iodine intake should always be medically supervised.

We’ve had customers with thyroid conditions who, with guidance from their doctors, were able to gradually reduce and eventually come off their medication by incorporating daily iodine supplementation. These stories have been incredibly heartwarming—but they also highlight how important it is to move slowly and carefully.

For instance, while we generally recommend 5 sprays per day for a healthy individual, some doctors advised their thyroid patients to begin with just one spray per day. After about a month of following this low-dose protocol, they’d re-test thyroid levels and slowly adjust—slightly increasing iodine while gradually reducing medication. Over the course of a year, some have successfully transitioned off their medication entirely.

This is a clear example of how personalized and cautious this process must be. Supporting the thyroid is essential, but for those with thyroid issues, special care and professional guidance are key.

Iodine for Children, Pregnancy & Lactation

Our iodine formulation aligns with established RDA guidelines.

Safe for children ages 1+ (follow label dosing by age group)
Recognized within recommended dietary intake guidelines
Health Canada–aligned dosage guidance

Pregnant and lactating women require higher iodine intake, as iodine is critical for fetal and infant neurological development. All age-specific and pregnancy/lactation guidelines are listed on the label.

Iodine Beyond the Thyroid

Iodine is used by many tissues throughout the body.

1. Breast Health

Breast tissue contains a high concentration of iodine receptors.

Research has explored iodine’s role in:

Supporting normal breast tissue structure
Maintaining healthy cellular function
Supporting hormonal balance in breast tissue

(For general educational reading, see National Institutes of Health resources on iodine and breast tissue physiology.)

2. Hormonal Balance

Iodine interacts with endocrine tissues and may play a supportive role in:

Ovarian health
Menstrual cycle regulation
General endocrine function

Healthy iodine status supports normal hormone signaling pathways.

3. Brain Health & Cognitive Function

Thyroid hormones (which depend on iodine) are critical for:

Memory
Focus
Cognitive clarity
Neurological development

Iodine is especially important during:

Pregnancy
Infancy
Early childhood

The World Health Organization recognizes iodine deficiency as a leading preventable cause of developmental impairment globally.

4. Metabolic Health

Because thyroid hormones regulate metabolism, adequate iodine supports:

Energy production
Temperature regulation
Normal metabolic function

5. Skin Health

Iodine has traditionally been valued for:

Supporting normal skin appearance
Maintaining healthy tissue
Acne

Important note:

Iodine is not significantly absorbed through intact skin.
Topical use is supplemental to — not a replacement for — internal intake.
If using topically, continue internal intake as directed on the label.

6. Immune System Support

Iodine contributes to normal immune system function and plays a role in maintaining mucosal health.

A Gentle Reminder

Iodine is powerful because it supports one of the body’s master regulatory systems — the thyroid. But supporting the thyroid requires patience and monitoring.

We have seen many encouraging stories from customers working closely with their doctors. Each journey is unique, and safety always comes first.
