We examined the relationship between vitamin C intake and the risk of developing kidney stones in a large cohort. This study included a significant number of participants: 156,735 women from the Nurses' Health Studies and 40,536 men from the Health Professionals Follow-up Study.
Our findings revealed that total and supplemental vitamin C intake was linked to a higher risk of kidney stones in men, but there was no such association evident in women. Specifically, among men, those who consumed higher amounts of vitamin C had greater likelihoods of developing stones when compared to those with lower intakes.
However, dietary vitamin C did not show a connection with kidney stones in either men or women. This suggests that while supplements may pose risks for men, dietary sources of vitamin C might not have the same impact. Overall, the study indicates that we should be cautious about high vitamin C supplement consumption, especially for men, while highlighting that dietary intake appears safe.

We set out to investigate whether high doses of intravenous vitamin C (IVC) could influence the formation of kidney stones. Our study involved 157 adult patients receiving IVC therapy at Integrated Health Options clinic over a 12-month period.
Throughout the study, we conducted regular check-ins with patients, specifically asking about any kidney stones they might have experienced, along with monitoring their renal function through blood tests. Despite some patients having a prior history of kidney stones, we found that none reported developing new stones during the study.
Interestingly, we also noted that the majority of participants showed stable renal function, as indicated by consistent serum creatinine levels and estimated glomerular filtration rates (eGFR). In summary, our findings suggest that IVC therapy does not appear to be associated with an increased risk of kidney stones.

We examined how different vitamin C formulations affect kidney stones, particularly focusing on Ester-C. This well-structured study utilized a randomized, double-blind, crossover design to assess the impact of Ester-C compared to regular ascorbic acid.
We found that Ester-C significantly lowered urine oxalate levels, a key risk factor for kidney stones. This discovery could be a promising step forward, but it also emphasizes the need for further clinical studies to fully understand its effects.

Safe for kidneys
This vitamin C is superb; Ester-C is the most optimal form, easily digestible. It enhances immunity, acts as a strong antioxidant, and slows the ageing process. It regulates blood pressure, positively impacts joint and cardiovascular diseases, and helps combat stress. It doesn’t irritate the stomach or digestive tract and is safe for the kidneys. The anti-stress and soothing effects are commendable while toning all body systems. It notably aids immunity and speeds recovery from colds, serving as a primary preventative measure.

We examined the relationship between dietary antioxidant intake, particularly vitamin C, and the risk of developing kidney stones. Utilizing data from the National Health and Nutrition Examination Survey, we found that individuals with higher levels of antioxidants, as indicated by the Composite Dietary Antioxidant Index (CDAI), had lower odds of forming kidney stones.
Stone formers, those who have experienced kidney stones, typically had a lower CDAI, showcasing significant differences based on gender. An interesting aspect of our findings was that vitamin C stood out as having the strongest negative correlation with kidney stones, suggesting that increased intake may be beneficial.
The results indicated that those in moderate and high CDAI groups had reduced odds of experiencing kidney stones compared to the lowest group. This was reflected in the odds ratios, which showed a significant decrease for those with higher antioxidant consumption. Therefore, it seems that a diet rich in antioxidants, particularly vitamin C, could play a role in lowering kidney stone risks.
However, while our findings are promising, we emphasize the need for more in-depth cohort studies to further investigate this potential connection and confirm its causal nature.

Vitamin C may reduce kidney stones
We explored the dietary habits of individuals from the National Health and Nutritional Examination Survey (NHANES) to see how certain foods might influence kidney stone formation.
Our focus was particularly on vitamin C and its potential role in preventing these painful stones. We looked at a diverse group of nearly 17,000 people, analyzing their dietary intake alongside their kidney health over a span of several years.
Interestingly, our findings highlighted a connection between higher vitamin C intake and reduced kidney stone risk. Specifically, we noted that individuals consuming 60 to 110 mg of vitamin C daily had a lower chance of forming stones, with an even greater protective effect observed in those exceeding that amount.
While we didn't find significant associations with many other dietary elements, our results suggest that increasing vitamin C intake might be beneficial. This points towards a need for further research on how vitamin C and other dietary factors interact in the context of kidney stone prevention.

We examined how different forms of vitamin C affect kidney stones, specifically looking at hyperoxaluria, a key risk factor for stone formation. In our study, conducted as a randomized, double-blind, crossover trial, we compared the effects of traditional ascorbic acid with a formulation containing vitamin C and metabolites, known as Ester-C.
Our findings revealed that Ester-C significantly lowered urine oxalate levels compared to regular ascorbic acid. This is exciting because higher oxalate levels in urine can lead to kidney stones, and finding a formulation that mitigates this risk is important.
Although this study presents promising results, it's essential to note that further evaluation is necessary to fully understand these findings. We believe this is a novel insight into the potential of vitamin C to help prevent kidney stones, and we look forward to additional research in this area.
