- Diet: Eliminate refined sugar, other refined carbohydrates, and caffeine. Restrict the intake of high-oxalate foods. Patients with sodium-induced hypercalciuria should consume a low-salt diet. Adequate amounts of liquid should be consumed. Do not restrict dietary calcium; however, if calcium supplements are used, they should be taken with meals.
- Vitamin B6, 10-50 mg/day, has been reported to reduce urinary oxalate excretion. Higher doses may be needed to normalize urinary oxalate in some cases, and up to one gm/day has been used for primary (hereditary) hyperoxaluria. Watch for signs of vitamin B6 toxicity with doses greater than 200 mg/day.
- Magnesium, 300-500 mg/day: Magnesium, either alone or in combination with 10 mg/day of vitaminB6, has been reported to reduce recurrences by approximately 90%. Magnesium increases the solubility of calcium oxalate. Supplementation with magnesium citrate would be expected to increase urinary excretion of citrate, which is an inhibitor of stone formation. However, magnesium citrate has not been studied as a treatment for recurrent kidney stones.
- Vitamin A (15,000 IU/day) if deficient: Vitamin A deficiency increases the risk of calcium-oxalate stones.
- Rice bran, 10 gm 2 times per day after meals, has been reported to reduce the recurrence rate of calcium-oxalate stones by more than 80% (uncontrolled trial). The mechanism of action is not known.
- Cystone, an oral Ayurvedic herbal combination: 78% ofm50 patients who took Cystone passed their kidney stones, compared with 24% of 50 controls (Probe 1982;21(4):281-287).
For all types of stones:
- Eliminate refined sugars and carbohydrates from the diet. Magnesium, vitamins A, B6, and C are removed during refining.
- Reduce consumption of all meats, especially red meats, such as beef and pork.
- Consume more whole, unprocessed, and unrefined foods, such as whole grains, vegetables, fruits, and nuts.
For calcium oxalate stones:
- Eliminate from the diet foods high in oxalate: beet tops, chard, cocoa, cola, parsley, rhubarb, spinach, and tea.
- Magnesium (chelated), 100 mg twice daily or magnesium oxide, 100 mg, 3 time daily.
- Vitamin B6 (pyridoxine), 50 mg, 2 times daily.
Note: In order to balance the whole B-complex group, it would be wise to increase all of the B vitamins. We recommend taking a super B capsule containing about 50 mg of each of B1 (thiamine), B2 (riboflavin), B3 (niacin or niacinamide), B6 (pyridoxine) of course, B5 (pantothenic acid), PABA, and Inositol; B2 (hydrocyanocobalamin), and Biotin, 50 mcg each; Folic acid, 200 mcg; Choline, 200 mg.
- Vitamin C (ascorbic acid), no more than 2-3 grams daily in divided doses.
For calcium phosphate stones: add
- Vitamin A, 60,000 to 120,000 IU*
- Vitamin E, 400-800 IU*
* International Units. Oil-soluble vitamins (A & E) can be taken once daily.
For uric acid stones:
Anything which would correct the excess production and elimination of uric acid would also prevent uric-acid stone formation. Essentially, strictly follow recommendations 1 and 2 for all types of stones. Consider becoming a vegetarian.
For primary oxalosis:
Vitamin B6 (pyridoxine), 1,000 mg in divided doses.
Drink two quarts of water daily.
