Some herbal supplements may harm chronic kidney patients, Kidney Foundation warns\
The National Kidney Foundation in the United States has warned that over-the-counter herbal supplements and vitamins may pose serious health risks for people with chronic kidney disease, stressing that the belief that “natural” products are always safe can be misleading.
In a report published on its official website, the foundation explained that damaged kidneys may struggle to filter and remove certain active ingredients found in supplements, causing them to build up in the body and potentially reach harmful levels.
The accumulation of these substances can worsen kidney damage, interfere with essential medications, including blood pressure and immune-suppressing drugs, and disrupt electrolyte balance, particularly potassium and phosphorus levels, which can lead to serious complications.
The foundation highlighted several supplements requiring caution, including:
Diuretic herbs such as dandelion and juniper, which may cause dehydration and disturb electrolyte balance.
Fat-soluble vitamins including vitamins A, E and K, which can accumulate in the body and become toxic when taken in excessive amounts.
Potassium and phosphorus supplements, which should only be used under medical supervision due to the risk of dangerous blood level changes.
Herbs such as St. John’s wort, ginkgo biloba and turmeric, which may interact with kidney medications and reduce their effectiveness.
The foundation urged kidney patients to inform their doctors about all supplements they use, including multivitamins, herbal products, probiotics and specialty teas, even if they appear harmless.
It advised patients to follow a kidney-friendly diet designed with medical guidance and obtain essential nutrients through appropriate food sources whenever possible.
The foundation stressed that products considered beneficial for healthy individuals may carry risks for people with kidney disease, making medical advice essential before using any supplement.
