Understanding kidney disease and protein needs 

You must be aware that our  kidneys play an essential role in filtering out waste from our bodies. However, the filtering process becomes impaired in renal diseases and it leads to toxins build-up in our body.

Although protein is essential for several reasons including growth and repair, it must be limited in such cases. The dietary restrictions only tend to increase as the kidney disease progresses to the end stage. 

Naturally, determining the appropriate amount of protein becomes a hectic and daunting task for many. We won’t be surprised if you find yourself asking, “How. much protein do kidney patients need?”

In simple words, protein intake for people at an early stage of kidney disease can be high but it must be reduced as the disease becomes more and more severe. 

In technical words, kidney patients who don’t have diabetes must consume a maximum of 0.8 grams per kg of body weight every day.

It is essential to note that consuming too much protein can lead to excess strain on the kidney. Whereas, too little protein consumption can lead to muscle wasting, malnutrition, and other health issues. 

By understanding how much protein kidney patients need, you can prepare an apt dietary plan for you and your loved ones. This will not only slow down the progress of the disease but also prevent unnecessary complications. 

Types of protein supplements for kidney patients 

Following a kidney-friendly diet is difficult. People don’t just have to limit their protein intake but ensure that the food doesn’t have high potassium, phosphorus, and sodium either. Therefore, the best option is to attain daily protein requirements through kidney-friendly protein supplements

Note: Pre-dialysis or non-dialysis patients should not consume protein powder since they are following a lower-protein diet.

There are several different types of protein supplements and some of them are as follows:

  1. Whey Protein 

Whey Protein is one of the most sought supplements in the market. The primary reason is its capacity to absorb quickly. This makes it much more effective for athletes, bodybuilders, and fitness enthusiasts. 

However, the protein is derived from milk which makes it an impossible option for people who are lactose intolerant or have advanced kidney disease. People with kidney or liver disease must also avoid high intake of whey protein because it can increase the workload on these organs.

  1. Casein Protein 

Casein is yet another popular supplement that acts slower as compared to whey protein. It’s the best choice for people who want prolonged slow release of protein. It is often used by athletes and bodybuilders who want nighttime recovery or a slower digestion rate. 

Since casein protein also comes from milk, it is unsuitable for lactose intolerant people. Apart from this, people with kidney or liver disease must also limit their intake of casein protein supplements. 

  1. Soy Protein 

It is one of the excellent kidney-friendly protein supplements which is low in fat and cholesterol. It’s safe to conclude that soy protein makes a good choice for vegans and vegetarians. 

Like any other supplement, however, a particular group of people cannot consume it. This mainly includes people with soy allergies because it may result in allergic reactions. Additionally, people with hypothyroidism must also avoid this supplement as it may impair thyroid gland function.

  1. Egg white Protein 

Egg white contains high-quality protein that is low in fat, cholesterol, and other nutrients such as potassium and phosphorus. This makes it a good alternative for lactose intolerant and soy allergic people. 

However, if you have an intolerance towards egg whites, you must strictly avoid this protein supplement as it can upset your digestive system and result in skin rashes. In some cases, it can also increase the workload on our kidney and liver.

  1. Collagen Protein 

Collagen protein is one of the popular supplements in the market that is known for its low phosphorus and sodium level. The product is an excellent option for people who want to improve their nails, hair, and skin along with overall health.

The supplement is normally well-tolerated by most but some people may experience digestive issues. Moreover, collagen protein supplements are derived from animal sources which makes them unsuitable for vegetarians or vegans.

  1. Hemp Protein 

Hemp protein is a plant-based supplement that has low sodium and phosphorus levels. This makes it a good alternative for vegans and vegetarians. Especially since this protein supplement is easy to digest.

However, one must be aware that hemp may contain trace amounts of psychoactive components found in marijuana. People who are subject to drug testing such as athletes must avoid using hemp protein supplements.

  1. Rice Protein 

Rice protein is yet another plant-based protein supplement that has low levels of phosphorus and sodium. So, it is an excellent option for people who prefer plant-based products. Additionally, it is easy to digest in nature. 

Some people may experience digestive issues when using rice protein supplements. People who have celiac disease and gluten sensitivity cannot have this supplement.

Precautions and safety measures 

When you don’t know the guideline, protein supplements can do you a lot of harm. Therefore, you must always take precautions and safety measures into consideration. Some things to keep in mind are as follows: 

  1. Consult your Nephrologist 

Before you start a new supplement or diet regimen, you must always consult your Nephrologist. They can offer you personalized recommendations based on your unique health needs and medical history. 

They can also help you determine an appropriate daily protein intake, identify any potential risks or interactions with other medications or supplements, and recommend kidney-friendly protein supplements that are safe for you to use. 

  1. Monitor protein intake 

When it comes to people with advanced kidney disease, they have a very small margin of protein requirement. Consuming too much protein can increase the workload on your kidneys and may worsen kidney function. Moreover, maintain a healthy weight and avoid overeating.

By keeping a close eye on your protein intake, you can ensure that you’re regularly eating the right amount of protein and meeting the daily requirements.

  1. Choose kidney-friendly protein supplements 

Not every supplement is made equally. Some may have high levels of potassium, phosphorus, and sodium. These nutrients may build up in the bloodstream and cause complications. 

Some protein supplements may also contain added sugars and preservatives which can further contribute to impaired kidney function. So, it’s better to choose a supplement that aligns well with your goal and health conditions. 

  1. Avoid supplements with added ingredients 

As a kidney patient, one of your priorities must be to avoid supplements that have additional ingredients such as artificial sweeteners, colors, flavors, preservatives, or herbs. 

It can add a significant amount of strain on your kidneys or interfere with your existing medications. In fact, some additives may even trigger adverse reactions and result in symptoms such as skin rashes, digestive issues, or respiratory problems. 

Therefore, it is wiser to opt for supplements that are much purer and simpler. 

  1. Stay hydrated 

When consuming protein supplements, the kidneys work harder to process the protein, so maintaining proper hydration levels is essential to support their function. 

It also helps to dilute waste products in the urine, reducing the risk of their accumulation and potential complications. 

This is particularly important for people who must manage their waste product levels in blood such as urea or creatinine. So, staying hydrated must be one of your priorities while focusing on protein consumption.
