Another year of relief (Low-oxalate diet)

Here you can share your experiences with substances that are ingested, inhaled, or otherwise consumed for the purpose of relieving RLS, other than prescription medications. For example, herbal remedies, nutritional supplements, diet, kratom, and marijuana (for now) should be discussed here. Tell others of successes, failures, side effects, and any known research on these substances. [Posts on these subjects created prior to 2009 are in the Physical Treatments forum.]

Important: Posts and information in this section are based on personal experiences and recommendations; they should not be considered a substitute for the advice of a healthcare provider.

What is the correlation with vitamin C and the low oxalate diet?

I have found fairly contradictory information. Maybe @XenMan knows more about this.

Vitamin C might be metabolized to oxalate https://www.ncbi.nlm.nih.gov/pubmed/27002809, https://pubmed.ncbi.nlm.nih.gov/8126804/ and could thus lead to higher oxalate load.

However, this view is controversial. A quick search yielded http://orthomolecular.org/resources/omns/v09n05.shtml which looks decent at first glance. Apart from limitatations of some studies, any acid would tend to dissolve oxalate crystals, therefore acids like vitamin C could increase excretion of oxalates via urine. In any case we know that vitamin C does not increase the likelyhood of oxalate kidney stones https://jasn.asnjournals.org/content/10/4/840.

To digress a little: There also seems to be a carbohydrate connection. https://pubmed.ncbi.nlm.nih.gov/572722/ claims that a diet high in refined carbs (flour etc.) could cause calcium oxalate kidney stones, probably coming from hyperinsulinemia https://doi.org/10.1111/j.1442-2042.2010.02661.x. Now a high carb diet routinely increases oxidative stress and reduces antioxidants, so high carb is usually associated with increased vitamin C requirements. Or conversely, we know cases like the Inuit where people would consume hardly any vitamin C in their diet, but they were perfectly healthy because they didn't consume any carbs (or oxalates). That would also indicate that consumption of vitamin C could be beneficial.
