Candida Overgrowth and Oxalate Production: The Overlooked Connection

The Overlooked Connection

Most people associate oxalates with dietary intake from high-oxalate foods like spinach, nuts, and beets. However, oxalates can also be produced internally, and one surprising source is Candida overgrowth.

If you’re dealing with symptoms like fatigue, joint pain, urinary issues, or digestive discomfort, and you suspect both Candida and oxalate sensitivity, understanding this connection is crucial.

How Candida Overgrowth Leads to Oxalate Production

Candida albicans is a type of yeast that naturally exists in small amounts in the gut. However, factors like antibiotic use, high-sugar diets, stress, and a weakened immune system can cause it to overgrow, leading to gut dysbiosis and systemic inflammation.

Research suggests that Candida overgrowth can increase oxalate production in the body. Here’s how it happens:

1. Candida Produces Oxalates Directly
   
   • Certain fungi, including Candida albicans, have been shown to produce oxalates as a metabolic byproduct.
   • If Candida is thriving in the gut, it may be contributing to high oxalate levels, even if your diet is low in oxalates.
2. Candida Disrupts Gut Bacteria That Break Down Oxalates
   
   • The gut contains beneficial bacteria like Oxalobacter formigenes, which help break down and eliminate oxalates before they can enter the bloodstream.
   • Candida overgrowth can crowd out these helpful bacteria, reducing oxalate breakdown and leading to higher oxalate levels in the body.
3. Leaky Gut Worsens Oxalate Absorption
   
   • Candida overgrowth is a major contributor to leaky gut syndrome, where the intestinal barrier becomes more permeable.
   • A damaged gut lining allows more oxalates to enter the bloodstream, leading to symptoms like joint pain, fatigue, and kidney stress.
4. Candida Feeds on High-Oxalate Foods
   
   • Some high-oxalate foods, like nuts, chocolate, and certain grains, also promote Candida growth by providing fermentable sugars.
   • This creates a vicious cycle where Candida overgrowth increases oxalate production, and a high-oxalate diet further fuels Candida.

Symptoms of Candida-Driven Oxalate Sensitivity

If you have Candida overgrowth and high oxalates, you might experience:

• Frequent urinary issues (burning, urgency, interstitial cystitis-like symptoms)
• Joint pain and stiffness (oxalates can form sharp crystals in tissues)
• Chronic fatigue and brain fog (oxalates disrupt mitochondrial function)
• Digestive discomfort (bloating, constipation, or diarrhea)
• Skin rashes or eczema (Candida and oxalates both contribute to inflammation)
• Tingling, numbness, or burning sensations (oxalates can irritate nerves)

If you suspect Candida-related oxalate issues, addressing both the Candida infection and oxalate metabolism is key to recovery.

How to Reduce Oxalates While Treating Candida

1. Balance Oxalate Intake Gradually

• Avoid drastic oxalate reductions because sudden oxalate dumping can cause flare-ups.
• Slowly transition to a moderate oxalate diet, focusing on low-oxalate vegetables and proteins.
• Avoid Candida-feeding high-oxalate foods like almonds, peanuts, chocolate, and grains.

2. Address Candida Overgrowth

• Use antifungal support like:
  
  • Caprylic acid (from coconut oil)
  • Berberine
  • Oregano oil
  • Garlic extract
  • Probiotic strains like Saccharomyces boulardii
• Minimize sugar and refined carbs, as Candida thrives on glucose.

3. Support Oxalate Breakdown in the Gut

• Increase gut-friendly bacteria that break down oxalates, such as:
  
  • Oxalobacter formigenes (if available in probiotic form)
  • Lactobacillus plantarum (found in fermented foods)
  • Bifidobacteria species
• Consider calcium citrate with meals to bind oxalates in the gut before they enter the bloodstream.

4. Heal the Gut Lining

• Bone broth, L-glutamine, and collagen help repair leaky gut.
• Aloe vera and marshmallow root soothe gut inflammation.

5. Optimize Detox Pathways

• Hydration: Drink 2-3 liters of water daily to help flush oxalates.
• Sweating: Far infrared saunas can help eliminate oxalates and Candida toxins.
• Magnesium and B6: These nutrients support oxalate metabolism and kidney function.

The Bottom Line

Candida overgrowth and high oxalates are often linked, creating a cycle of gut dysfunction, inflammation, and nutrient imbalances.

If you’re dealing with Candida symptoms alongside oxalate-related issues, focus on:

• Gradually reducing oxalates
• Eliminating Candida overgrowth
• Supporting gut health and oxalate metabolism

By addressing both dietary and internal sources of oxalates, you can reduce symptoms and restore balance to your system.
