    What Is Vitamin C

    Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is critical to tissue growth and repair in our bodies. Vitamin C helps to heal wounds, form scar tissue, maintain structure of bones and teeth, and absorb iron. Signs of vitamin C deficiency, commonly known as scurvy, include leg weakness, easy skin bruising, and swollen gums. Vitamin C deficiency is relatively uncommon in the United States and Canada because many food items such as juices are fortified with vitamin C. Vitamin C is found naturally in foods such as oranges, guavas, sweet peppers, grapefruits, and kiwis.

    How Much Vitamin C Is Too Much

    Since vitamin C is water-soluble and your body excretes excess amounts of it within a few hours after you consume it, its quite difficult to consume too much.

    In fact, it is nearly impossible for you to get too much vitamin C from your diet alone. In healthy people, any extra vitamin C consumed above the recommended daily amount simply gets flushed out of the body .

    To put it in perspective, you would need to consume 29 oranges or 13 bell peppers before your intake reached the tolerable upper limit (

    19 ).

    All the adverse effects of vitamin C, including digestive distress and kidney stones, appear to occur when people take it in mega doses greater than 2,000 mg .

    If you choose to take a vitamin C supplement, it is best to choose one that contains no more than 100% of your daily needs. Thats 90 mg per day for men and 75 mg per day for women .


    Its nearly impossible to consume too much vitamin C from food. However, if youre supplementing with this vitamin, you can minimize your risk of getting too much by taking no more than 90 mg per day if youre a man, or 75 mg per day if youre a woman.

    Vitamin C is generally safe for most people.

    This is especially true if you get it from foods, rather than supplements.

    Individuals who take vitamin C in supplement form are at greater risk of consuming too much of it and experiencing side effects, the most common of which are digestive symptoms.

    Impair The Effectiveness Of Niacin

    Too much of this vitamin can lead to kidney stones!

    Evidence suggests that taking vitamin C supplements may impair the bodys ability to increase high density lipoprotein cholesterol in people taking the combination drug niacin-simvastatin. This drug combines the vitamin niacin with the statin simvastatin , and people take it to treat high cholesterol.

    Doctors consider HDL cholesterol the good cholesterol because it reduces the amount of harmful cholesterol in the blood.

    If a person takes vitamin C supplements and niacin-simvastatin, they should talk to their doctor about ways to make each more effective. Doctors do not know whether vitamin C also affects the ability of other medicines similar to Zocor.

    A persons body cannot make vitamin C, so people need to eat enough foods that contain vitamin C to meet their daily needs. If someone is at risk of a vitamin C deficiency, they can take vitamin C supplements.

    The advise aiming for the following RDA of vitamin C each day:

    90 mg 75 mg

    People who smoke should take 35 mg more vitamin C per day than those who do not smoke.

    During pregnancy or when breastfeeding, women should get the following levels of vitamin C per day:

    • 1418 years: 80 mg during pregnancy and 115 mg when breastfeeding
    • 19 years and older: 85 mg during pregnancy and 120 mg when breastfeeding

    There is not enough research to suggest an RDA for vitamin C in those younger than 1 year of age. As a result, the ODS provide an adequate intake, which is the amount that is likely to be sufficient:

    Vitamin D: The Kidney Vitamin

    Many Americans are deficient in an important vitaminvitamin D. The Centers for Disease Control and Prevention’s latest information has found that more than one-half of Americans of all ages have low levels of vitamin D. More and more information is pointing to how important vitamin D is to the body, especially the strength of bones.

    In addition to maintaining healthy bones, newer research shows that vitamin D may also protect against heart disease. In fact, people with the lowest vitamin D levels had a 40% higher risk of cardiovascular disease in one study.

    Talk with your doctor or dietitian before taking any vitamins that are not ordered for you. There are different types of vitamin D. Your doctor will be very specific about the type and amount you should be taking.

    Why is vitamin D connected to the kidney? The kidneys are an important part of helping the body use vitamin D. Vitamin D comes from two sources in people. It could either be exposure to the sun’s ultraviolet B radiation. Or, it is absorbed from food or food supplements. The kidneys have an important role in making vitamin D useful to the body. The kidneys convert vitamin D from supplements or the sun to the active form of vitamin D that is needed by the body. With chronic kidney disease, low vitamin D levels can be found, sometimes even severely low levels. This may occur because injured kidneys are less able to convert vitamin D into its active form.

    COVID-19 patients can become kidney patients.

    G Dosing Considerations For Patients With Renal Failure Who Are Not On Rrt

    Removal of vitamin C by the kidney depends on plasma concentration. In case of hypovitaminosis tubular reabsorption is maximal and removal is minimal while losses are higher when plasma concentrations are high. In patients with severe AKI, plasma concentrations following IV administration are expected to be significantly higher, especially in anuric patients. Thus, dose reduction is needed in patients with renal failure who do not require RRT. Since no guidelines are found in the literature, dosing 12;g/day vitamin C dosing seems to be most appropriate to avoid overdosing in this population.

Enteral uptake is unpredictable and may be seriously limited because the enteral transporter is satiable and gut function often is impaired during critical illness. Second, high vitamin C doses must be administered to restore plasma concentrations to normal and sustained therapy is needed to prevent reoccurrence of hypovitaminosis . Third, a very high dose is required to obtain supranormal plasma concentrations . Studies which showed beneficial effects on biological and clinical outcome parameters used very high vitamin C doses on the first day of admission in burn patients and 3;g, 6;g or 200;mg/kg daily in septic or trauma patients .
