Collagen Side Effects on Kidneys

Taking collagen can have some negative side effects on the kidneys, but there are some ways you can avoid these problems.

Increased oxalate excretion

Several dietary supplements are available that contain 10 grams of collagen per recommended dose. These supplements are safe for most people, but should be avoided by people with kidney stone problems or metabolic disorders.

Collagen is a protein found in meats and other foods. It contains the amino acid hydroxyproline. It has been reported that consuming large amounts of hydroxyproline increases urinary oxalate excretion.

Oxalate is a compound that binds to calcium in the digestive tract. Oxalate can obstruct the flow of urine, causing painful urination and even kidney stones. However, most kidney stones pass naturally with increased water intake.

The kidneys contain enzymes that break down oxalate. The oxalate-calcium compound is also excreted through the urine as dissolved calcium-oxalate. Increasing dietary calcium may help to reduce the risk of kidney stones.

Research shows that oxalate levels in the urine increase for six hours after eating 5 to 10 grams of gelatin. However, this is not the case when the gelatin is consumed at lower doses.

During a study, researchers measured oxalate excretion in the urine, and glycolate clearance from the kidney. They found that glycolate clearance was 5.3-fold higher in the gelatin diet than in the whey diet. This was likely due to the increased glycolate load on the kidney.

Plasma glycine levels doubled after ingestion of gelatin. Despite the fact that glycine is a by-product of hydroxyproline metabolism, it is not known where glycine comes from.

It is possible that hydroxyproline from gelatin supplements can help the body reduce its oxalate load, though further investigation is needed. The gastrointestinal tract has difficulty breaking down supplements, so it is important to take the recommended dosage.

Some patients with kidney stone problems may experience symptoms such as nausea, vomiting, constipation, and fatigue. For this reason, you should discuss your condition with your health care provider before taking any collagen supplement.


Taking too much collagen could be harmful to your kidneys. This is because of the presence of hydroxyproline, a compound that may increase your urinary oxalate output.

Unlike other protein sources, collagen contains a lot of large molecules that are difficult for your body to break down. Moreover, most of us need between 46 and 56 grams of protein per day. Luckily, collagen supplements can help protect your joints from wear and tear.

The first phase of the study included a small sample of 40 participants. Two video interviews were held with each participant. This provided a good overview of their lifestyle, as well as their dietary habits. At the end of the 6 week trial, ninety-three percent of the participants reported a positive improvement in their digestive symptoms.

The second phase was a two-week, mixed methods digital study. The streetbees app was used to collect survey data and answer questions on a variety of topics. The app was approved by a German regulatory agency.

The main objective of the study was to determine whether collagen supplementation would improve digestive symptoms. Researchers hypothesized that, as well as other benefits of collagen, the supplement might reduce bloating. Although not a definitive answer, the data showed that bloating due to collagen side effects was a non-issue. The bloating score on the app was a decent indicator of this fact.

The study’s most noteworthy findings include a lower-than-expected bloating score on the one-third of the participants who took the collagen. This could be related to the fact that overweight participants have a reduced microbiome diversity. Similarly, they likely have a skewed idea of how a lot of bloating is caused by a high-protein diet.


Taking too many collagen supplements can spell trouble. The best way to go about this is to start small. The best approach is to consult a healthcare provider. This will ensure you get the most out of your dietary supplements.

One of the first things you should look for is a supplement that aims to replicate the functions of natural human collagen. For this purpose, you may be interested in some peptides. You can find these supplements in the form of pills, capsules or gummy supplements. They come in various flavors such as berry, chocolate and kiwi. The best way to take advantage of these supplements is to combine them with a healthy diet and regular exercise. This will reduce the risk of kidney stones in the future. A diet rich in fruits, vegetables and whole grains will ensure your body receives a healthy dose of nutrient dense food. It will also provide you with the nutrients your body needs to function properly.

Choosing a reputable company is also a must. The best providers are the ones that do not cut corners. The best ones are transparent and will ensure that you get the most out of your dietary supplement. In addition, the best practitioners will be able to answer all your questions and more. You can even have your own bespoke consultation. In conclusion, a collagen supplement may sound like a good idea, but you’ll be thankful you did it if you end up with a kidney stone.

Hairline cracks in nails

Besides the normal cracks in your nails, you may notice some flaky patches on your nails. If you are experiencing some of the above symptoms, it is a good idea to see your healthcare provider. They can prescribe medicine for you to treat the problem. Also, you may want to consider applying a lotion with alpha-hydroxy acid to the affected area to soothe the skin.

If your nail cracking is persistent, your doctor can prescribe anti-fungal pills. These medications are often painted on your fingernails like nail polish, which helps to kill the fungus. If the infection is severe, your nail may need to be removed. You can also try applying a paraffin wax bath to your hands to help moisturize them.

You may also suffer from psoriasis, which can also cause your fingernails to crack. If you have psoriasis, you can use topical ointments or creams to treat your nails. If your nails crack and turn blue, you may have a melanoma, which is a serious form of skin cancer. You can also look for dark lines beneath your nails to get a better idea of what’s going on.

Symptoms of an allergic reaction

Taking collagen supplements can cause some interesting side effects. For example, the supplement may raise your calcium levels, which may be a good thing for some people, but for others it can lead to kidney stones. And it may also raise your urinary oxalate levels, which can cause symptoms like diarrhea and constipation.

The good news is that if you are prone to kidney stones, taking a small amount of collagen a day is unlikely to cause them. And if you have a history of kidney stones, you might want to avoid taking collagen altogether. For the most part, the side effects will fade as your body gets used to the suppleness of collagen.

However, many people do not respond to collagen products. For example, some are sensitive to the free glutamic acid in the protein. And there are serious quality issues with some of these supplements. There are also reports of people getting headaches or a stomach ache from taking some of these supplements. This is probably due to the amino acids in the protein. The best bet is to get your collagen from a bone broth rather than a supplement. And, if you are a fish eater, you might want to try some of the marine sourced versions instead.

There are also a number of other side effects of taking collagen. In addition to the obvious constipation and digestive tract problems, the dietary supplement may cause an allergic reaction, which can include symptoms such as abdominal pain, itching and tingling, and vomiting.
