No, you generally should avoid potassium supplements if you have kidney disease, as damaged kidneys struggle to remove excess potassium, leading to dangerous buildup (hyperkalemia) that can cause heart problems. Always consult your doctor or a renal dietitian before taking any supplements, as they can assess your blood levels and create a kidney-friendly diet plan, often restricting high-potassium foods like bananas, avocados, and salt substitutes.
About Potassium
People living with kidney disease are at risk for having potassium levels outside of the goal range (either too high or too low). To keep your potassium levels in the goal range, you may need to watch how much potassium you are eating throughout the day.
Potassium is essential for kidney function. Too much or too little potassium can affect this function and lead to complications. Potassium plays a key role in a number of bodily processes, including nerve transmission, heart contractility, cellular transport, and normal kidney function.
What vitamins should a CKD patient avoid? The fat soluble vitamins (A, D, E and K) are more likely to build up in your body, so these are avoided unless prescribed by your kidney doctor. Vitamin A is especially a concern, as toxic levels may occur with daily supplements.
Before taking potassium,
It helps control your fluid balance, muscle contractions and nerve signals, including those that keep your heart working properly. It also reduces the effect of sodium on blood pressure. While potassium is vital for many body functions, too much can be harmful for some people, especially those with kidney disease.
Potassium citrate is used to treat a kidney stone condition called renal tubular acidosis. It is also used to prevent kidney stones that may occur with gout. Potassium citrate is a urinary alkalinizer. It works by making the urine more alkaline (less acid).
Over-the-counter NSAIDS
They are not safe to use when you have kidney disease. Ibuprofen, such as Advil™ and Motrin™. Naproxen, such as Aleve™ and Naprosyn™. Aspirin for pain relief.
Here's a breakdown of the six most common supplements people with CKD may need to support kidney health.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
The 2010 Academy of Nutrition and Dietetics CKD guidelines recommend that patients with CKD stage 3–5 who have hyperkalemia limit their dietary potassium intake to <2.4 g/d (17).
Potassium affects the way your heart's muscles work. When you have too much potassium, your heart may beat irregularly, which in the worst cases can cause heart attack.
More severe cases of low potassium may cause signs and symptoms such as:
Take action to prevent, delay, or manage CKD:
Table salt, some seasonings, ketchup, mustard, and certain sauces such as barbecue, soy, and teriyaki sauces are high in sodium. The 2020–2025 Dietary Guidelines for Americans recommends adults limit their sodium to no more than 2,300 milligrams per day. Many people with CKD need to limit their sodium even more.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
Vitamins A, E, and K usually don't need to be taken as supplements if you have CKD. Most people get enough of these vitamins in their diet, even with CKD. Also, your body stores these vitamins to use later. So, taking too much can cause a buildup in your body and be harmful.

Current clinical research has shown that magnesium administration in people with CKD is safe, without concerns for severe hypermagnesemia or negative interference with bone metabolism.

Can I increase my GFR score?
People with certain kidney disorders (such as interstitial nephritis or kidney damage resulting from sickle cell anemia) may also urinate excessively because these disorders also decrease the amount of fluid reabsorbed by the kidneys. Rarely, urinary frequency is caused by spinal cord injury or disorder.
Some people, such as those with kidney disease or who are taking certain medications, should consult their health care provider before taking salt substitutes because of the risk of hyperkalemia posed by the high levels of potassium in these products.
You should not use potassium citrate if you have kidney failure, a urinary tract infection, uncontrolled diabetes, a peptic ulcer in your stomach, Addison's disease, severe burns or other tissue injury, if you are dehydrated, if you take certain diuretics (water pills), or if you have high levels of potassium in your ...
