How to eliminate toxins and take care of your kidneys with these natural tricks and remedies

Maintaining kidney health is essential to prevent problems ranging from minor infections to chronic diseases or kidney failure. A diet high in salt or animal protein, lack of hydration, overuse of painkillers, or certain metabolic diseases can overload the kidneys. This overload can ultimately promote the formation of kidney stones or progressively reduce their filtering capacity. Although the body performs this cleansing process on its own, certain habits and natural remedies can facilitate it.

One of the most accessible and evidence-backed methods is consuming lemon juice . According to a clinical trial published in The Lancet , adding 60 milliliters of lemon juice twice a day to the diet helped reduce the recurrence of kidney stones in patients with lithiasis, by increasing urinary citrate levels, a substance that inhibits the crystallization of calcium oxalate. Lemon's alkalizing effect and its contribution of citric acid make it an effective natural support for keeping the kidneys free of waste.

Of course, constant and sufficient hydration remains the foundation of any strategy to care for these organs. Drinking between two and two and a half liters of water a day facilitates the elimination of toxins through the urinary tract and reduces the concentration of minerals that could form stones. Although there is no exact amount for everyone, it is recommended to adjust intake based on each person's physical activity, ambient temperature, and health status.

Fruits and infusions with a diuretic effect

In addition to lemon, some fruits with a high water content, such as watermelon and pomegranate , can help in a complementary way. Watermelon, rich in lycopene and potassium salts, has a mild diuretic effect and promotes the acid-base balance of urine. Pomegranate, for its part, provides antioxidants and potassium, which help prevent crystal formation and improve waste excretion. Both can be easily integrated into a balanced diet.

Some vegetables with a high water content and natural diuretic compounds can also help keep the kidneys healthy. Celery, for example , is known for its apiol and antioxidants like apigenin, which promote fluid elimination. Other vegetables such as cucumber, onion, and asparagus can be easily incorporated into the diet to support the body's cleansing function without resorting to artificial products.

As for traditional herbal remedies, dandelion is one of the most studied. For example, a small clinical trial published in the Journal of Alternative and Complementary Medicine found that its extract significantly increased urine production in healthy people. Its ability to lower blood pressure and exert a mild anti-inflammatory effect has also been investigated, which could benefit those seeking natural support without drugs. Parsley or horsetail infusions are also frequently used, although prolonged use without medical supervision should be avoided.

Finally, controlling salt intake , reducing animal protein , and prioritizing fresh foods over ultra-processed foods remains key. These measures not only help prevent kidney disease but also protect other organs such as the heart and liver. Although there is no single or foolproof remedy, incorporating these habits can contribute to long-term kidney health.
