Healthy kidneys remove waste. When they become less efficient, Renadyl™ helps your intestinal bacteria participate in handling part of that waste, reducing the overall metabolic burden on your body.

Doctor's Answer The medications prescribed for Chronic Kidney Disease each have a specific purpose. Some control blood pressure, others help manage diabetes, reduce protein loss in the urine, correct anemia, or control phosphorus and potassium levels. These treatments remain the foundation of CKD management. Renadyl™ has a different role. It does not replace any medication or interfere with how your treatment works. Instead, it focuses on an area that prescription drugs generally do not address—the intestinal environment and its role in handling certain waste compounds that accumulate as kidney function declines. Think of Renadyl™ as an addition to your treatment plan, not an alternative to it. Its purpose is to complement the care you already receive, not to replace therapies that have been prescribed by your nephrologist. Many people with CKD benefit from a combination of medication, appropriate nutrition, blood pressure control, and lifestyle changes. Renadyl™ is designed to fit into that comprehensive approach.

This is probably the most common question I hear from patients. The honest answer is Renadyl™ is not designed to regenerate damaged kidneys or cure Chronic Kidney Disease. Once kidney tissue has been permanently damaged, no probiotic, medication, or supplement can restore it to normal. What Renadyl™ is designed to do is address one of the consequences of reduced kidney function. As the kidneys become less efficient, waste products accumulate in the body and changes occur in the intestinal microbiome. Renadyl™ helps modify this intestinal environment by introducing carefully selected probiotic bacteria that participate in the metabolism of certain nitrogen-containing waste compounds. For many patients, the goal is not to reverse kidney disease but to support kidney health, reduce the metabolic burden associated with CKD, and help maintain stability for as long as possible alongside the treatment prescribed by their nephrologist. Your blood tests—including creatinine, eGFR and urea—remain the best way to evaluate how your kidneys are functioning over time. Renadyl™ should be viewed as part of a comprehensive management plan, not as a replacement for medical treatment.

Doctor's Answer Renadyl™ is not designed to produce immediate results. Like most probiotics, it needs time to establish its activity in the intestine. Many people begin to notice changes after about one month of consistent daily use, although the response varies from person to person. Factors such as the stage of Chronic Kidney Disease, overall health, diet, and other medical conditions can all influence how quickly changes are observed. Because Chronic Kidney Disease is a lifelong condition, Renadyl™ is intended to be taken every day as part of your long-term kidney care plan. Just as blood pressure medication or a kidney-friendly diet only work while they are maintained, the benefits of Renadyl™ depend on consistent, ongoing use. Your nephrologist will continue to monitor your kidney function through routine blood tests, including creatinine, eGFR, and urea, to assess the overall management of your condition.

Doctor's Answer Yes. Renadyl™ is designed to be taken every day. The beneficial bacteria in Renadyl™ are living microorganisms. To provide continuous support, they need to be replenished regularly. Taking the product only occasionally or stopping it for long periods may reduce the consistency of its intended effect. Chronic Kidney Disease is a long-term condition. Just as your kidney-friendly diet or prescribed medications are part of your daily routine, Renadyl™ is intended to become part of your everyday kidney care. If you forget to take a dose, simply continue with your normal schedule the following day. There is no need to take extra capsules to make up for a missed dose.

Doctor's Answer Yes. Renadyl™ is designed to be used alongside the treatment prescribed by your nephrologist, not instead of it. Because Renadyl™ works in the intestine and is not absorbed into the bloodstream like a medication, it does not have the same type of interactions that prescription drugs can have with one another. If you are taking phosphate binders, antibiotics, or other medications that must be taken at specific times, it is generally a good idea to separate them from Renadyl™ by at least 2 hours, unless your physician advises otherwise. This gives the probiotic bacteria the best opportunity to reach the intestine. Always continue taking your prescribed medications exactly as directed by your healthcare provider. Renadyl™ is intended to complement your treatment plan, not replace any part of it.

Doctor's Answer Renadyl™ is intended to become part of your long-term kidney care routine. Like other probiotics, its beneficial bacteria do not permanently colonize the intestine. Their activity depends on regular, daily supplementation. If you stop taking Renadyl™, those bacteria gradually decrease over time, and the intestinal environment returns to its previous state. The benefits you've gained from continuous supplementation are therefore unlikely to be maintained indefinitely without ongoing use. Because Chronic Kidney Disease is a lifelong condition, Renadyl™ is designed to provide continuous support throughout the course of the disease, not as a short-term treatment. If you need to stop taking Renadyl™ for any reason, discuss it with your healthcare provider so they can advise you based on your individual condition.

Doctor's Answer Renadyl™ contains live probiotic bacteria. Like all living organisms, they are naturally more stable when kept at cooler temperatures. Refrigeration doesn't make Renadyl™ more effective—it simply helps preserve the quality and activity of the probiotics, so each capsule delivers the intended number of live beneficial bacteria. Before opening, Renadyl™ is stable during normal transportation and can safely travel for up to 14 days without refrigeration, provided it is protected from direct sunlight and excessive heat. Once your Renadyl™ arrives, simply store it in the refrigerator (4–8°C / 39–46°F). This helps preserve the live probiotic bacteria and ensures the product maintains its intended quality from the first capsule to the last.

Renadyl™ Support Yes. Renadyl™ has been specifically formulated and tested to remain stable during transportation for up to 14 days without refrigeration. During shipping, we carefully monitor weather conditions across Europe. If extreme heat could affect delivery, we may delay shipment by one or two days to ensure your order arrives in optimal condition. This is done to protect the quality of the live probiotics. Once your Renadyl™ arrives, simply store it in the refrigerator (4–8°C / 39–46°F). This helps preserve the live probiotic bacteria and ensures the product maintains its intended quality from the first capsule to the last.

Doctor's Answer For best results, take 2 capsules once daily, approximately one hour before a meal, with a glass of water. Taking Renadyl™ before eating allows the capsules to pass through the stomach before food stimulates digestion, giving the probiotics the best opportunity to reach the intestine, where they are intended to work. The most important factor, however, is consistency. Try to take Renadyl™ at the same time each day so it becomes part of your daily routine. If you occasionally take it later than planned, don't worry. Simply continue with your normal schedule the following day.

No. Renadyl™ capsules should be swallowed whole whenever possible. The capsules are specially designed to protect the live probiotic bacteria as they pass through the acidic environment of the stomach. Opening, crushing, or chewing the capsules may reduce the number of bacteria that reach the intestine, where they are intended to work. If you have difficulty swallowing capsules, speak with your healthcare provider before altering the product. They can advise you on the most appropriate way to take Renadyl™ based on your individual circumstances.

Doctor's Answer Every person is different. Some people report feeling more energetic or notice an improvement in their overall well-being after taking Renadyl™ consistently for several weeks. Others don't notice any obvious day-to-day changes at all. This doesn't necessarily mean the product isn't working. Chronic Kidney Disease often progresses slowly, and many of the changes associated with treatment are not something you can feel from one day to the next. The best way to evaluate your kidney health is through regular follow-up with your nephrologist and routine blood tests. Renadyl™ is intended to become part of your long-term kidney care, whether or not you notice immediate changes.

Doctor's Answer Yes. Renadyl™ was developed for long-term, continuous use. Chronic Kidney Disease is a lifelong condition, and managing it requires a long-term approach. Just as maintaining a kidney-friendly diet, controlling blood pressure, and taking prescribed medications become part of your daily routine, Renadyl™ is intended to provide ongoing nutritional support throughout your CKD journey. Renadyl™ is not designed as a short-term course or a treatment to be taken for only a few weeks. If your nephrologist recommends Renadyl™, it should become part of your daily kidney care for as long as it continues to benefit your overall management plan.

Doctor's Answer Yes. Renadyl™ can be taken at any stage of Chronic Kidney Disease. Whether you've recently been diagnosed with early-stage CKD or have more advanced kidney disease, the goal remains the same: to support your kidney health as part of your overall treatment plan. Many patients choose to start Renadyl™ soon after diagnosis, while others begin taking it later in the course of their disease. There is no “perfect” time to start—the important thing is to use it consistently as part of your long-term kidney care. If you are receiving dialysis or have recently undergone a kidney transplant, speak with your nephrologist before starting any new dietary supplement so it can be appropriately integrated into your treatment plan.

Not every nephrologist is familiar with every dietary supplement available for patients with Chronic Kidney Disease. Nephrologists primarily focus on diagnosing kidney disease, prescribing medications, managing blood pressure, diabetes, anemia, mineral balance, and determining when dialysis or transplantation may be necessary. Nutritional supplements are not always part of routine medical practice, and awareness of specific products can vary from one physician to another. Renadyl™ has been available for many years and has been evaluated in clinical studies, but like many nutritional supplements, it may not be discussed during every consultation. If you're interested in taking Renadyl™, bring it to your next appointment. Your nephrologist knows your medical history and can advise whether it is appropriate for your individual treatment plan.

Doctor's Answer Yes. One of the challenges of Chronic Kidney Disease is that many people feel perfectly well, especially in the early stages. In fact, it's common for kidney function to decline gradually without causing noticeable symptoms. The absence of symptoms doesn't necessarily mean the kidneys are healthy or that the disease has stopped progressing. For this reason, treatment decisions are based on your kidney function, blood tests, and your nephrologist's assessment—not simply on how you feel. If Renadyl™ has been recommended as part of your kidney care plan, it should be taken consistently, even if you feel completely normal.

Yes. Renadyl™ can be given to both cats and dogs to support their kidney health. It uses the same probiotic approach as the human product — a unique, science-backed formulation that works in the gut to help metabolize the nitrogenous waste compounds that accumulate as kidney function declines. Rather than only managing symptoms, it works at the source, which makes it a valuable addition to your pet's kidney-care routine. Dosage: one capsule per day, or as directed by your veterinarian. Storage: keep refrigerated (4–8°C / 39–45°F) and do not freeze — the same as the human product. How to give it: the capsule can be given with food. Renadyl™ is designed to support your pet's kidney health alongside — not replace — the care and treatment prescribed by your veterinarian. Always consult your vet before starting any new supplement, especially for a pet with a diagnosed condition such as chronic kidney disease.

Probiotics are living microorganisms that have beneficial effects on the human body. Certain probiotics have been studied for their role in supporting kidney function in people with impaired or damaged kidneys. Three types of bacteria have been specially selected for use in Renadyl: Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium longum.

By metabolizing nitrogenous waste compounds in the gut, these probiotics help ease part of the waste burden associated with impaired or damaged kidneys, supporting the body's natural elimination of those compounds.

Many strains of probiotics are found in yogurt. However, the pasteurization process kills natural organisms, so the presence of live probiotics can be unpredictable, and most manufacturers add bacteria back after pasteurization with varying effectiveness. Many yogurts contain around 10 billion CFU. By contrast, Renadyl is standardized to contain a high level — 45 billion CFU — of the three bacteria selected for kidney health in each serving, up until the expiration date.

Renadyl uses three proprietary, patented strains: Streptococcus thermophilus (KB19), Lactobacillus acidophilus (KB27) and Bifidobacterium longum (KB31). They were specially selected for their high affinity for creatinine, urea and uremic acids, which they metabolize in the gut, and are delivered in gastric acid-resistant capsules so they survive stomach acid and reach the intestine.

Prebiotics are naturally occurring fiber materials that probiotics use to help them grow. Renadyl contains the prebiotics inulin and xylo-oligosaccharide.

Synbiotics are supplements that contain both prebiotics and probiotics. Most probiotics on the market today, including Renadyl, are considered synbiotic — because a probiotic, without its prebiotic food, does not survive as well in the digestive system.
