GFR = -0.883 x AGE + 167.398
If your eGFR value is at or above what the GFR value is with that formula, you have kidney hyperfiltration, which is a bad sign and you need to see a doctor or tell your doctor you have the new definition of hyperfiltration.
Do not use the newer eGFR weight & height correction for body size, as they found it does not work to properly identify any relevant hyperfiltration determination.
This has relevance for me. My eGFR value, done without body size correction, is 104. With body correction, it’s over 135. With the formula above, I am 16 below the new formula approach for where hyperfiltration is a problem. Instead, it just shows my kidneys are very healthy and not actually dysfunctional (might be the GlyNAC and other supplements and foods I have posted here).
They tested this with a lot of patients using the actual GFR test with inulin, instead of the estimated GFR from creatinine or Cystatin C, as these two are not safely accurate with hyperfiltration patients. When you have hyperfiltration, your kidney cells are going crazy flushing your blood, and the concern is that they die off or go into senescence, leaving you with damaged kidneys. However, an accurate GFR test uses inulin and is time based and your kidneys are accurately tested for this condition.
I read studies and it showed I should have gone to a kidney doctor and had the insulin test, but I just believed all the studies were wrong.
With this new study, I realize I was right, just without the proof or understanding.
Makes me need to take a leak.....

My GFR, by that calculation formula, is 101.173, even though I have Stage 2 Mild kidney disease.
I don’t know eGFR I have on record was 80 and this calculation for me is 104. So I guess I’m clear.
Yet recently I’ve worried about my kidneys. A couple weeks back I ran some tests and they came back all clear. No problems. I thought maybe I had an infection because I have bph and infections happen from time to time. But even the cultured labs came back clean. At the time I had the problem my urine smelled fishy and I had a slight pain in my right side. I think I got rid of smell by drinking cranberry juice with lemon juice and apple cider vinegar. The slight pain in my lower left side wanders around my lower left side. so that might be muscle pain.
I asked perplexity.ai what supplements might cause kidney problems. This was the answer:
Several supplements have been reported to potentially cause kidney problems, especially in individuals with pre-existing kidney conditions or those taking certain medications. Here are some supplements that may cause kidney issues:
Vitamin C: High doses (1 gram or more daily) can increase the risk of kidney stones, particularly in people with a history of kidney stones15.
Creatine: This supplement, often used for muscle building, can strain the kidneys, especially when combined with strenuous exercise and dehydration45.
Chromium: Used for weight loss, chromium has been associated with kidney dysfunction in some case reports5.
Turmeric/Curcumin: In large amounts, it may lead to kidney damage, especially in people taking immunosuppressive drugs1.
Herbal supplements: Several herbs are considered risky for kidney health, including:
Astragalus
Cat’s Claw
Creatine
Licorice Root
Uva Ursi
Yohimbe34
Minerals: Excessive intake of potassium, calcium, magnesium, and phosphorus can affect kidney function1.
Lysine: High doses over extended periods have been linked to chronic renal failure in some cases5.
It’s important to note that the safety of supplements can vary depending on an individual’s health status, medication use, and kidney function. Always consult with a healthcare provider before starting any new supplement regimen, especially if you have kidney disease or are at risk for kidney problems26.
I asked perplexity.ai what supplements might help strengthen the kidneys. This was the answer.
Several supplements have shown potential to support kidney health and function, though it’s important to note that their effectiveness can vary depending on individual circumstances. Here are some supplements that may help improve kidney function:
Vitamin D: This vitamin is crucial for kidney health, as damaged kidneys have difficulty converting it into its active form. Supplementation may help slow the progression of chronic kidney disease (CKD)1.
Iron: Essential for producing healthy red blood cells, iron supplementation can be beneficial for those with kidney-related anemia1.
B Vitamins: Specifically, vitamin B9 (folic acid) and B12 are important for kidney health. They help produce healthy red blood cells and may slow down rising phosphorus levels in people with kidney disease14.
Probiotics: These beneficial bacteria can help protect against CKD complications by decreasing inflammation and the production of uremic toxins, potentially improving kidney function24.
Alpha Lipoic Acid (ALA): This antioxidant may help address cardiovascular complications associated with kidney disease3.
Resveratrol: Found in berries, grapes, and peanuts, resveratrol has shown kidney-protective properties in animal studies23.
Moringa: Animal studies suggest that moringa leaf extract may protect against kidney toxicity and decrease levels of waste products in the blood3.
Omega-3 fatty acids: Some studies indicate that omega-3 supplementation may help improve kidney function5.
Caution and Consultation
It’s crucial to remember that while these supplements show promise, their effects can vary. Some supplements may interact with medications or be contraindicated for certain kidney conditions. Always consult with a healthcare provider or nephrologist before starting any new supplement regimen, especially if you have existing kidney issues or are at risk for kidney problems.
