How Nephure Works - The Science

Nephure contains an enzyme called oxalate decarboxylase. This enzyme splits oxalate into smaller compounds naturally present in your body. The reaction starts with the enzyme binding oxalate ultimately pulling it apart into smaller pieces resulting in reduced oxalate levels.

Frequently Asked Questions

  • What is oxalate and where does it come from?

    Oxalate is the chemical outcome of metabolism in plants. While oxalate serves an important role in the growth and regulatory functions of plants, it serves no known benefit for your body. Oxalate that you consume becomes a waste product and is disposed of through the kidneys and urinary tract. Oxalate is also considered an “anti-nutrient” because it binds with nutrients we need, like calcium, magnesium and iron, making them less available for your body.

  • How does oxalate affect us?

    Oxalate is considered an “anti-nutrient” because it binds with nutrients we need, like calcium, magnesium and iron, making them less available for your body. The oxalate you consume through your diet becomes a waste product and is disposed of through the kidneys and urinary tract.

  • What is the recommended oxalate intake per day?

    If recommended to be on a low-oxalate diet, the ideal oxalate intake is about 50 mg per day. For reference, the average person consumes about 250 mg of oxalate per day.

  • How do you define a food/beverage low in oxalate?

    We define low-oxalate foods to have between 0 - 2 mg of oxalate per 100 g serving. Medium or moderate levels are defined as 2-10 mg per 100 g serving; any servings above 10 mg of oxalate are considered high.

  • What is a low-oxalate diet?

    The traditional low-oxalate diet requires reducing or eliminating oxalate-packed foods, which include anything from spinach and nuts to potatoes and chocolate. A low-oxalate diet is recommended to a growing number of people as part of an overall program to help maintain kidney and urinary tract health. Please check with your healthcare professional for more information on things to include in your kidney health program.
