Kelp is a type of brown seaweed commonly used in supplements for its rich iodine content and trace minerals. It is often promoted for thyroid support, which is essential for metabolic rate regulation, energy production, and overall hormonal balance—key factors in maintaining physical performance and body composition.
The high iodine content in kelp plays a critical role in the production of thyroid hormones (T3 and T4), which influence metabolism and energy utilization in the body. This can be particularly relevant for athletes or active individuals looking to support metabolic efficiency.
In addition to iodine, kelp contains antioxidants, polysaccharides, and alginates, which may offer further health benefits including immune support and digestive aid.
Synonyms:
Brown seaweed, Ascophyllum nodosum, Laminaria.
Benefits:
- Supports thyroid health and metabolism
- Provides essential trace minerals (e.g., iodine, iron, calcium)
- May enhance energy balance and endurance
- Contains antioxidants that aid recovery
Sources:
Harvested from cold ocean waters; often dried and milled into powder.
Observations:
Found in tablets, powders, or multinutrient blends. Excessive iodine intake can disrupt thyroid function—moderation is important.
