Why does Vitals⁺ include Iodine?

Iodine is essential for maintaining thyroid health, which affects your energy, metabolism, and brain. But due to low levels in soil and food, iodine deficiency is still common across Europe—especially for those on plant-based diets.

Vitals⁺ provides 152mcg of iodine from potassium iodide, delivering 101% of your daily NRV—just over the sweet spot to fully support thyroid hormone production and long-term health.

🤔 What does Iodine actually do?

Iodine is a key building block of thyroid hormones (T3 and T4). These hormones:

• Support energy-yielding metabolism, helping convert food into energy

• Contribute to cognitive function, including memory and attention

• Help produce thyroid hormones, which regulate nearly every cell in your body

• Support foetal and infant brain development, making it especially important for women of childbearing age

🤔 Why potassium iodide—and why that dose?

We use potassium iodide because it’s stable, well-absorbed, and effective—the gold standard in both food fortification and supplementation.

EFSA sets the Adequate Intake (AI) for adults at 150mcg/day. Our 152mcg dose aligns with this—enough to:

• Keep you in optimal range for thyroid hormone synthesis

• Support your long-term iodine stores

• Stays well below the Tolerable Upper Limit of 600mcg/day for adults
