Kelp

Discover why kelp is one of nature's richest sources of iodine and why it has been valued for supporting normal thyroid function.

Kelp is a large brown seaweed belonging to the Laminaria family that grows in nutrient-rich coastal waters around the world. It has been consumed for centuries as both a food and a traditional nutritional ingredient, particularly in East Asian countries.

Kelp is naturally one of the richest dietary sources of iodine, an essential mineral required for the normal production of thyroid hormones. Because iodine plays such an important role in thyroid health, kelp has become a popular ingredient in nutritional supplements designed to support normal thyroid function.

What is Kelp?

Kelp is a type of large brown seaweed that naturally absorbs minerals from seawater. Among these minerals, iodine is present in particularly high amounts, making kelp one of the richest natural dietary sources available.

Kelp & Iodine

Iodine is an essential mineral that the body cannot produce on its own. It is required for the normal production of thyroid hormones, which help regulate metabolism, energy production, growth and many other important physiological processes. Kelp naturally provides iodine in a whole-food source.

Supporting Normal Thyroid Function

The thyroid gland uses iodine to produce the hormones thyroxine (T4) and triiodothyronine (T3). Without adequate iodine intake, the thyroid cannot produce these hormones efficiently. Kelp is widely used in nutritional supplements because of its naturally high iodine content and its long history of traditional use.

Hormonal Balance

Supports normal hormonal health and wellbeing.

Energy Production

Supports normal energy-yielding metabolism and helps reduce tiredness and fatigue.

Brain Function

Supports normal cognitive function, memory and mental performance.

Healthy Inflammatory Response

Supports the body's normal inflammatory response.

What is kelp?

Kelp is a large brown seaweed that grows in coastal waters. It is naturally rich in iodine and has been consumed as a food for centuries.

Why is kelp rich in iodine?

Kelp absorbs minerals directly from seawater as it grows. This allows it to naturally accumulate iodine, making it one of the richest dietary sources of this essential mineral.

Why is iodine important for the thyroid?

Iodine contributes to the normal production of thyroid hormones, which help regulate metabolism, energy production, growth and normal nervous system function. Adequate iodine intake is essential for healthy thyroid function.

Can you consume too much iodine?

Yes. Although iodine is essential, excessive intake over long periods is not recommended. It is important to follow the recommended serving size, particularly when using kelp supplements, as iodine levels can vary naturally.

Is kelp the same as other seaweeds?

No. Kelp refers to several species of large brown seaweeds within the Laminaria group. While many seaweeds contain iodine, kelp is generally one of the richest natural sources.
