The real culprit in kidney stones is uric acid, not ascorbic acid. Uric acid is known to cause stones, conclusively.
With vitamin C, the RDA is only enough to prevent scurvy, NOT to promote optimum health., That is because promoting optimum health is against the business interests of the drug companies.
Remember, the AMA was founded by Rockefeller to sell drugs.
If you promote optimum health, you prevent disease, and that is bad for the business of the drug companies, and fast food and junk food companies. That's a lot of money, and a lot of power against promoting optimum health and disease prevention.
Of course, promoting optimum health reduces flu vaccine sales too...
