Why does it matter?

Iodine is an essential trace element, but how it is sourced matters significantly. Many iodine supplements rely on isolated iodine salts or poorly controlled seaweed powders, which can lead to large variability in iodine content.

Vitamine uses a standardized extract of Fucus vesiculosus L., a brown seaweed traditionally valued for its naturally occurring iodine. The iodine in Fucus exists in both inorganic and protein-bound forms, reflecting its natural biological matrix, rather than a single isolated compound.

This extract is water-extracted, preserving the integrity of the plant material while avoiding harsh solvents. It is standardized to ≥ 0.2% total iodine, ensuring consistent iodine delivery with microgram-level precision — a critical factor for a nutrient where both deficiency and excess matter.

Additionally, the raw material is European-origin, wild-harvested, and subjected to rigorous quality controls, including limits on heavy metals, pesticides, microbiological contamination, and environmental pollutants. This ensures a clean, reliable, and traceable iodine source, aligned with Vitamine’s science-first and safety-focused approach.

In short, this is iodine in its most controlled, natural, and physiologically relevant form, designed for precision supplementation.

Effects

Iodine is an essential micronutrient required for the production of thyroid hormones, which play a central role in regulating metabolism, energy production, and overall physiological balance. As a naturally iodine-rich seaweed, Fucus vesiculosus has been traditionally used as a dietary source of iodine in coastal diets.

By providing iodine in a carefully standardized amount, this ingredient supports normal physiological functions while respecting the body’s sensitivity to iodine intake.

SUPPORT FOR NORMAL THYROID FUNCTION
Iodine contributes to the normal production of thyroid hormones and normal thyroid function. Adequate iodine intake is essential for maintaining metabolic balance and supporting the body’s energy-regulating systems.

CONTRIBUTION TO ENERGY METABOLISM
Through its role in thyroid hormone synthesis, iodine contributes to normal energy-yielding metabolism, helping the body efficiently convert nutrients into usable energy.

ROLE IN COGNITIVE AND NERVOUS SYSTEM FUNCTION
Iodine contributes to normal cognitive function and the normal functioning of the nervous system, highlighting its importance beyond metabolism alone.

MULTIFACETED PHYSIOLOGICAL ROLES

Incorporating iodine into a personalized supplementation routine may support:

• Normal thyroid hormone production
• Energy metabolism
• Cognitive function
• Nervous system function
• Overall metabolic balance

Ensure you consult with a healthcare professional to determine your specific needs and to discuss any supplementation, particularly for nutrients such as iodine that require precise dosing.
