Is garlic good or bad for kidney disease?

“Is garlic good or bad for kidney disease?” is a question I get asked by many patients suffering from kidney diseases. Though used in small quantities, it is an important ingredient in many dishes.

I will try to answer this question in detail mentioning all the benefits of eating garlic for kidney diseases and whether there is any downside of garlic for CKD patients. 

How is garlic good for kidney disease?

Let’s start with the benefits of garlic for kidney patients. Garlic is found in pretty much every house in the world. It can be added to any dish while cooking for extra taste and flavor.

Garlic has a wide range of benefits for kidney patients. Garlic is loaded with nutrients that help the kidney function better.

A study has shown that allicin (a compound derived from crushing garlic) is beneficial for treating severe kidney diseases like CKD.

Studies have also shown that garlic may be helpful in promoting kidney health because of its diuretic properties. It signals the kidney to remove any excess toxins and minerals through urination.

The antioxidant, anti-bacterial, and anti-inflammatory properties of garlic make it a nutritionally dense food, especially for kidney patients as it helps in preventing further damage to the kidneys. 

High blood pressure is one of the major causes of kidney disease as it can damage the blood vessels in the kidney. When the kidneys are damaged they are unable to function efficiently.

The antioxidant properties of garlic are beneficial not only for patients with kidney disease but also for people suffering from hypertension, as it may reduce oxidative stress on the blood vessels and improve blood flow. 

How garlic can be bad for kidney disease?

Garlic is generally safe for consumption for kidney patients due to its numerous health benefits. It is not very likely that garlic would pose any further risk to the kidneys.

The only thing that might not be ideal for kidney patients is garlic salt or any other processed food items made out of garlic as they might contain high amounts of sodium which should not be eaten in large amounts by a chronic kidney disease patient. 

Eating too much garlic can cause bloating, digestive issues, bad breath, etc. Hence, just because garlic is healthy, it doesn’t mean that it should be eaten in large amounts.

Keep in mind that anything in excess is bad for the body, even water. So, enjoy the addition of garlic to add extra taste and flavor to your meals in normal amounts and avoid overeating it.

Is raw garlic good for kidney disease?

A study done on renal transplant patients indicated that eating raw garlic produced a positive result in reducing LDL cholesterol and triglyceride (fat in the blood) levels.

Hence, raw garlic is not only good for renal patients but also for people suffering from high cholesterol and triglyceride levels.

Is garlic good for kidney infection?

Garlic can be an effective remedy for kidney infection. Garlic has been used for centuries as a treatment for various diseases such as cough, digestive issues, hemorrhoids, etc. 

A study has shown that garlic could be effective in fighting urinary tract infections (UTI) and other bacterial infections, which is one of the reasons for an infected or an inflamed kidney.


Garlic is an excellent way to spice up the flavor in your food. As stated above, it has numerous health benefits. It lowers the bad cholesterol, fights off bacterial infections, and also aids in lowering blood pressure.

Garlic may also be useful in helping kidney disease patients to stay away from heart diseases. Therefore, it is an ingredient that should be included in the diet of a kidney patient.

  1. That information was really useful to me, as my husband is on dialysis. We know now that we can eat more porridge (organically grown oats) and that garlic and turmeric are good. We take turmeric in supplement form and garlic in cooking! We eat our porridge with honey and use organic soya ‘milk’.
    Thank you!

    • Hummus is high in potassium. If potassium levels are normal, then a small amount can be consumed occasionally.

      • Reducing creatinine/controlling it requires a multi pronged approach and there is no one medicine that will bring it down in all patients.

          • That’s not proven. Apple is a good fruit for kidney patients because of its low potassium content.

          • Have you or someone you know used Apple for that reason? They say an apple has over 465 nutrients and most they can’t identify if I remember correctly . Guess the saying, “ an apple a day keeps the doctor away” is one to remember !😀
