Rating (out of 5): 1

Kelp, a type of seaweed rich in iodine and various minerals, has been used traditionally in some cultures for a variety of health purposes, including general detoxification and support of bodily systems such as the thyroid gland. However, its specific use to support the urinary system is primarily rooted in traditional herbal and folk medicine rather than scientific validation. The rationale for its use in urinary health is often based on the belief that its mineral content—especially potassium and sodium—may help maintain electrolyte balance and potentially support kidney function. Yet, there is a lack of robust clinical research or scientific studies directly linking kelp intake with improved urinary system health or function. Most available evidence is anecdotal or based on general observations in traditional practices, not rigorous scientific trials. Thus, while kelp is sometimes included in herbal blends aimed at urinary or kidney support due to its nutrient profile, its efficacy for this specific use remains unproven in modern scientific literature. Caution is advised, as excessive consumption of kelp can lead to iodine toxicity and other health issues. In summary, kelp’s use for urinary system support is primarily traditional, and the quality of evidence supporting this specific application is low.
