Depending on the type of vitamins and minerals, an overdose may often lead to severe kidney damage. If you already suffer from a kidney disease, taking an overdose of a certain vitamin or mineral may aggravate the symptoms dramatically. You have to learn which vitamins and minerals may pose a threat to your health. The metabolism of many such nutrients takes place in the kidney and if you suffer from a disease that affects these organs, the toxicity effects may be noticed sooner than expected. More than that, dialysis depletes the body from certain nutrients, so you have to know which ones may need to be supplemented and which ones are harmful.
Vitamin A Toxicity
Vitamin A is a fat-soluble compound, which means that any excess gets deposited in the kidneys and liver. In patients with renal failure who receive total parenteral nutrition, vitamin A causes a toxic reaction. Over the counter supplements containing vitamin A may also be toxic when the recommended daily intake is exceeded. Symptoms seem to ameliorate as soon as the vitamin A supplementation is stopped.
Vitamin C and Kidney Disease
Even vitamin C, an otherwise rather safe nutrient, may be harmful for people suffering from kidney disease. At some point, it was even rumored that ascorbic acid is one of the causes of kidney stones, but studies eliminated this suspicion eventually. Chronic kidney disease patients who suffer from vitamin C deficiency are recommended to take between 60 and 100 mg per day. Doses exceeding the upper limit may lead to the formation of oxalate deposits in soft tissues and bones.
Vitamin D, Calcium and Kidney Stones
When taking too much vitamin D, calcium accumulates in the blood, leading to a health condition that is called hypercalcemia. One of the consequences of this condition is the development of kidney stones. However, by reducing the vitamin D and calcium intake, this problem can be avoided.
Over the Counter Potassium Supplements
Potassium influences directly the stability of your heart beats. In people with kidney diseases, the amount of potassium in blood is abnormal, a fact that may lead to heartbeats that are out of control. Potassium is often lethal if it is administered in very high doses. If you suffer from a renal disorder, you are highly recommended to avoid any over the counter supplements that contain this mineral.
Conclusion on Vitamins, Minerals and Kidney Diseases
Despite the fact that supplements that contain vitamins and minerals can be purchased without a prescription, as a renal disease patient you are highly recommended to talk to a health care provider. After determining which vitamins are deficient, the doctor will recommend a certain supplement and a certain dosage that must not be exceeded. If the dosage is respected with strictness, many of the harmful effects of these vitamins and minerals can be avoided. Keep in mind that the doctor may decide to eliminate completely such dangerous over the counter nutrients from your treatment. However, other vitamins may actually help kidney disease patients by significantly improving their condition.
