- They contradicts early in the day training which have demonstrably shown one highest dose ascorbate will not cause renal rocks.[2-6]
- The analysis authors’ conclusion one ascorbate was the cause of low rate off rocks is likely because of a relationship between your collection of bringing a nutritional C enhance with different facet of the participants’ diet plan.

The analysis our company is sharing did not tabulate the newest participants’ intake from oxalate, but typically they’d apparently large intakes (several servings) regarding tea and you may coffee. You’ll be able that people who had kidney stones got her or him before the research started, or got him or her in investigation, on account of an especially higher consumption out of oxalate. Including, the participants you to definitely grabbed supplement C was trying remain healthy, nevertheless the subset of them just who had renal stones may also had been seeking continue to be healthy by drinking an abundance of tea or coffee, otherwise eating green leafy produce like spinach.
