Renadyl Probiotics: Help For Kidney Disease?

The idea behind this supplement is intriguing and could be called enteric toxin removal technology. The supplement works in the colon (large intestine) to modulate the microbiome. According to the company, unique strains of probiotic bacteria consume nitrogenous waste products in food.

Nitrogenous waste, such as. B. Urea damages kidney function. When bacteria consume nitrogenous waste, they multiply and consume even more waste. When nitrogen waste is reduced, inflammation and free radical damage are also reduced.  All of these things can help your kidneys work better. Finally, you eliminate the microbes that consume the nitrogenous waste products in your stool.

The company calls this procedure intestinal dialysis. However, there are no clinical studies comparing the effect of traditional dialysis with that of Renadyl probiotic preparations.

What is BUN?

Urea is a product of the nitrogenous waste products created during the digestion of the proteins in the food you eat. Blood urea nitrogen (BUN) is the urea in your blood. Normally, the kidneys remove urea from the blood. As kidney function declines, urea nitrogen levels in the blood begin to rise. The worse your kidney function, the higher your BUN level will be. Typical BUN levels are between 7 and 20 milligrams per deciliter. This allows doctors to measure BUN levels as an indicator of healthy kidney function.

Ingredients Renadyl

One capsule contains 45 billion colony forming units (CFU) of the following species of bacteria:

  • Streptococcus thermophilus (KB 19)
  • Lactobacillus acidophilus (KB 27)
  • Bifidobacterium longifolia (KB 31)

The three types of Gram-positive lactic acid bacteria. Note that KB 19, KB 27 and KB 31 refer to bacterial strains. The strain is a specific type of bacteria found in the complement. All bacteria are natural and not genetically modified.

Other ingredients

The capsules also contain xylooligosaccharides, inulin, and magnesium stearate. Both inulin and xylooligosaccharides are prebiotics. Prebiotics are what probiotic bacteria eat in food.

Is Renadyl a medicine?

Although the manufacturer is called BioTech, Renadyl is a dietary supplement. A doctor’s prescription is not necessary. Renadyl is not a replacement for medication or kidney dialysis.

This probiotic has been the subject of clinical studies and the company that produces it (Kibow Biotech) supports research on its supplements. The following is a brief description of studies in humans.


In a study, 22 people with kidney disease were given either 6 capsules of Renadyl a day or a placebo for 2 months. The results showed no significant improvement in renal function in those who took the probiotic. Renadyl did not result in a decrease in the number of renal dialysis procedures.

The researchers showed that a probiotic reduced white blood cell counts, C-reactive protein (CRP), a marker of cellular inflammation, and a kidney toxin called indoxyl glucuronide. However, none of these reductions were significantly different from the placebo. However, no adverse side effects have been reported.

Study 2

In another study, 24 middle-aged adults with stage 3 or 4 kidney disease received different doses of the probiotic Renadyl to see if it was safe and what effect it had. The study lasted 6 months. At the end of the training, participants reported improvements in their physical functioning. However, there was no change in their pain scores, mental or emotional well-being. But most interestingly, according to the researchers, the application contributed to a significant reduction :

  • Creatinine
  • C-reactive protein (CRP)
  • Hemoglobin
  • Hematocrit

Does a probiotic kill the stomach?

The bacteria in the antacid capsules can enter the stomach without being destroyed by digestive juices such as hydrochloric acid. This increases the chance of bacteria entering the colon.

Does it need cooling?

It is recommended to store the supplement in the refrigerator for maximum efficacy. The company claims that Remadil is stable for up to 2 weeks without refrigeration.


Although clinical studies are the best evidence, some people with confirmed purchases on Amazon have reported that this kidney care supplement has helped them. Some even claim that Renadyl improves the glomerular filtration rate (GFR), although this has not yet been confirmed by researchers.

Different strains of bacteria can have different effects.  If you are looking for alternatives, researching the strains of bacteria used (RD 19, RD 27, and RD 31) may help.

Side effects of Renadyl

Is Renadil safe? For most people, it seems that way. In one study, researchers gave people with stage 3 or 4 kidney disease doses of 90, 180, and 270 billion colony-forming units for 6 months. This was equivalent to 2 capsules of the 4 and 6 capsules per day. No significant side effects were reported.

In human studies, side effects were minor. For example, some people have reported bloating. Online testimonials from those who have used the supplement have reported muscle cramps, stomach upset, and diarrhea. Side effects may vary.  Here are some general things to keep in mind when you start using this or any other new supplement.

  • For the first week, start with less than the recommended amount.
  • Please consult your doctor first if you are due to undergo surgery, are pregnant or breastfeeding, or if you are taking any medications.

Is Renadyl safe for pets?

The company has a version for cats and dogs, Azodyl, which has been around since 2006. No adverse effects were observed in dogs or cats. Azodil contains the same types of bacteria as Renadyl. Azodil gets its name from azotemia, a condition in which nitrogenous waste products accumulate in toxic amounts and can lead to kidney failure.

Does Renadyl work?

Preliminary data suggest that Renadyl Biotech by Kilbow Biotech may improve certain aspects of renal function, including B. lowering creatinine levels. However, whether it improves BUN or GFR filtration rate requires further study. So far, there is no evidence that this supplement reduces dialysis treatment or improves survival in patients with kidney problems. If this works, memory results may vary. The idea of using the microbiome to improve kidney health is intriguing and deserves further investigation. A high-fiber diet also improves the health and diversity of microbes.
