Vitamin C administration may also acidify the urine and could promote the precipitation of kidney stones or drugs in the urine. [20] Although vitamin C can be well tolerated at doses well above what government organizations recommend, adverse effects can occur at doses above 3 grams per day.
Vitamin C- Water-soluble vitamin that aids in keeping tissues healthy, wound healing, and infection prevention. [2] Vitamin D- Normally, the kidney changes vitamin D into its active form, vitamin D3, which helps with calcium absorption. Many dialysis patients have low intakes of calcium due to avoidance of foods containing phosphorus and potassium.
Vitamin C has a definitive role in treating scurvy, which is a disease caused by vitamin C deficiency. Beyond that, a role for vitamin C as prevention or treatment for various diseases is disputed, with reviews often reporting conflicting results. No effect of vitamin C supplementation reported for overall mortality. [105]
The US Recommended Dietary Allowance for vitamin C for adult women is 76 mg/day and for adult men 90 mg/day. Although Linus Pauling was known for highly respectable research in chemistry and biochemistry, he was also known for promoting the consumption of vitamin C in large doses. [ 25 ]
Men in both studies, on a diet devoid or nearly devoid of vitamin C, had blood levels of vitamin C too low to be accurately measured when they developed signs of scurvy, and in the Iowa study, at this time were estimated (by labeled vitamin C dilution) to have a body pool of less than 300 mg, with daily turnover of only 2.5 mg/day.
The kidney fails to respond adequately to PTH, which normally promotes phosphaturia and calcium reabsorption, or to FGF-23, which also enhances phosphate excretion. [2] In addition, there is evidence at the tissue level of a downregulation of vitamin D receptor and of resistance to the actions of PTH.
Overall, vitamin C shines brightest as a cold preventative rather than treatment. And Del Junco says if you focus on getting enough of the nutrient in your daily diet, it can help keep you from ...
Newborn infants are a special case. Plasma vitamin K is low at birth, even if the mother is supplemented during pregnancy, because the vitamin is not transported across the placenta. Vitamin K deficiency bleeding (VKDB) due to physiologically low vitamin K plasma concentrations is a serious risk for premature and term newborn and young infants.
