Can You Get Kidney Stones From Taking Collagen Supplements

Are collagen supplements the ticket to improved skin and joints, or may they cause kidney stones? Concerns about the safety and potential negative effects of collagen supple

ments have emerged as their use has grown. In this article, we answer the question: will taking collagen supplements cause kidney stones?

Understanding Kidney Stones

Kidney stones are hard deposits that grow in the kidneys and frequently cause excruciating pain when they move through the urinary tract. They vary in size and content, with calcium oxalate stones and uric acid stones being the most frequent. While there is no direct evidence linking collagen supplements to the production of kidney stones, it is crucial to investigate the factors that may contribute to their formation.

What Are Collagen Supplements?

Collagen is our bodies’ most prevalent protein, providing structure and support to our skin, joints, and other connective tissues. Collagen supplements, which come in powders, pills, and beverages, are promoted as a way to increase collagen levels and improve skin elasticity, joint health, and overall well-being. These supplements usually include hydrolyzed collagen, which has been broken down into tiny peptides for easy absorption.

The Link Between Collagen Supplements and Kidney Stones

The Link Between Collagen Supplements and Kidney Stones

The amino acid content of collagen may explain the probable relationship between collagen supplements and kidney stones. Collagen contains a high concentration of amino acids, especially hydroxyproline, which the body converts to glyoxylate. Glyoxylate is a precursor of oxalate, which is an important component of kidney stones. High oxalate levels in the urine can increase the likelihood of stone formation.

While collagen supplements do not directly cause oxalate synthesis, the hydroxyproline in them may contribute to an increase in oxalate generation in the body. This raises concerns about the potential function of collagen supplements in the production of kidney stones.

Studies on Collagen Supplements and Kidney Stones

There has been little research into the particular relationship between collagen supplements and kidney stones. Some research, however, have looked at the effects of collagen hydrolysate, a common type of collagen supplement, on urinary oxalate levels.

The effect of collagen hydrolysate on urinary oxalate excretion in healthy people was examined in one study published in the Journal of Renal Nutrition. There was no significant rise in urinary oxalate levels after consuming collagen hydrolysate, implying that collagen supplementation may not directly contribute to kidney stone development.

Another study published in the European Journal of Clinical Nutrition looked at the impact of collagen hydrolysate on urinary oxalate levels in people who have had kidney stones in the past. The researchers discovered that collagen hydrolysate did not significantly increase urinary oxalate excretion in these people, implying that collagen supplementation may not be a significant risk factor for stone development in this cohort.

While these studies shed some light on the potential impact of collagen supplements on urinary oxalate levels, additional study is required to establish a conclusive link between collagen supplementation and kidney stone development.

Factors That Contribute to Kidney Stone Formation

It is critical to understand that kidney stone production is a complex process impacted by a variety of factors. While collagen supplements may have a role, other factors such as food, hydration, genetics, and underlying medical issues can also play a role.

Dietary variables, especially a high intake of oxalate-rich foods such as spinach, rhubarb, and chocolate, can boost urinary oxalate levels and increase the risk of stone formation. Stone formation can be aided by dehydration, which results in concentrated urine. Furthermore, some medical diseases, such as hypercalciuria (excess calcium in the urine), hyperoxaluria (excess oxalate in the urine), and urinary tract infections, might increase the risk of forming kidney stones.

Limitations and Risks of Collagen Supplements

Limitations and Risks of Collagen Supplements

While collagen supplements are generally regarded safe for the majority of people, they do have some dangers and restrictions. When using collagen supplements, some people may develop digestive difficulties such as bloating, diarrhea, or constipation. These side effects are usually mild and transient, but it’s crucial to start slowly and monitor your body’s reaction.

Collagen supplements are made from animal collagen, primarily bovine (cow) or marine (fish). Individuals with dietary limitations, allergies, or ethical issues about animal products may be concerned about this. Furthermore, the quality and purity of collagen supplements can vary, so select reputable brands and check with a healthcare practitioner if you have any specific concerns or medical issues.

Alternatives to Collagen Supplements

There are various natural strategies to support collagen formation and overall skin and joint health if you’re looking for alternatives to collagen pills. A healthy diet rich in fruits and vegetables, lean meats, and whole grains supplies vital elements for collagen formation. Vitamin C-rich foods, such as citrus fruits, strawberries, and bell peppers, stimulate collagen formation. Foods high in antioxidants, such as berries, leafy greens, and almonds, can also help preserve collagen from damage.

Regular exercise, appropriate sleep, and stress management, in addition to a good diet, play critical roles in maintaining collagen levels and general well-being. Avoiding excessive sun exposure, quitting smoking, and limiting alcohol use are also good for collagen formation and skin health.

Tips for Preventing Kidney Stones

Tips for Preventing Kidney Stones

Whether you choose to use collagen supplements in your health routine or not, it is critical to take precautions to limit the risk of kidney stone formation. Consider the following suggestions:

  1. Stay Hydrated: Drink plenty of water throughout the day to maintain proper urine volume and keep urine from becoming excessively concentrated.
  2. Keep an eye on your diet: Limit your intake of oxalate-rich foods like spinach, rhubarb, and chocolate. Consider reducing your salt and animal protein consumption as well.
  3. Get Enough Calcium: Contrary to popular perception, getting enough calcium from meals can help prevent kidney stones. In the intestines, calcium binds to oxalate, decreasing its absorption into the circulation and urine system.
  4. Keep a Healthy Weight: Obesity and weight gain can increase the likelihood of kidney stone formation. To acquire and maintain a healthy weight, aim for a balanced diet and regular physical activity.
  5. Manage Underlying Medical Conditions: If you have any medical disorders that contribute to the formation of kidney stones, such as hypercalciuria or hyperoxaluria, work closely with your healthcare professional to properly manage them.

When to Seek Medical Advice

If you have severe back or side discomfort, blood in your urine, recurrent urinary tract infections, or difficulty passing pee, you should seek medical attention right once. These symptoms could indicate the presence of kidney stones or other underlying health conditions that need to be evaluated and treated by a physician.


While there is no direct evidence linking collagen supplements to kidney stone formation, it’s essential for me to consider the potential risks and factors that contribute to stone development. Collagen supplements may contain amino acids that can be converted to oxalate, a key component of kidney stones. However, existing research suggests that collagen supplementation may not significantly increase urinary oxalate levels or pose a significant risk for stone formation.

If I choose to incorporate collagen supplements into my routine, it’s crucial to choose reputable brands, start with a low dosage, and monitor my body’s response. Additionally, adopting a healthy lifestyle, including a balanced diet, regular exercise, hydration, and stress management, can support my overall well-being and help reduce the risk of kidney stone formation.

I’ll keep in mind that if I have any concerns or specific medical conditions, it’s always best to consult with a healthcare professional who can provide personalized advice and guidance.
