| name | Vitamin C |
| Classification | Water-soluble vitamin, antioxidant |
| Pharmacokinetics | Vitamin C is readily absorbed in the small intestine. It is transported in the blood, primarily bound to plasma proteins. High doses can be excreted in the urine, unlike fat-soluble vitamins. The body can store only limited amounts of vitamin C, hence the need for regular intake. |
| suggested dosage | The recommended daily allowance (RDA) for vitamin C in adult males is 90 mg per day. This can vary depending on specific factors (e.g., smoking status, stress). Higher doses may be considered in specific situations, but this should be discussed with a healthcare professional. It's best to obtain vitamin C from a balanced diet rather than relying on supplements, unless specifically recommended by a doctor. |
| indications | Vitamin C is crucial for various bodily functions including collagen synthesis, immune function, and antioxidant protection. Common indications include: preventing and treating scurvy (vitamin C deficiency); supporting immune function during illness; wound healing. |
| Safety in pregnancy | Adequate intake is important during pregnancy. However, high doses in pregnancy may not be safe, or may be unnecessary, and should be discussed with an obstetrician. There is concern about potential impacts on the baby's iron absorption. |
| Safety in breastfeeding | Adequate intake is important during breastfeeding. The risks of high doses are generally considered to be limited if the mother is healthy, and not taking extreme doses. Consult with a healthcare professional. |
| side effects | Generally well-tolerated at recommended doses. High doses (>1000 mg/day) can lead to gastrointestinal upset (e.g., nausea, diarrhea, abdominal cramps), kidney stones, and other less common issues. Individual reactions may vary. |
| alternatives | |
| contraindications | Individuals with certain underlying conditions (e.g., kidney disease, hemochromatosis, and in rare cases certain genetic disorders) may require careful monitoring or have contraindications to Vitamin C supplementation. Talk with a healthcare professional. |
| interactions | Vitamin C can interact with some medications, including certain chemotherapeutic agents, and potentially interfere with the absorption of other drugs. Always discuss any supplements or medications with your doctor. |
| warnings and precautions | Consult with a healthcare professional before taking any vitamin C supplement, especially if you have any existing medical conditions. Do not self-treat or make significant changes in vitamin intake without a professional recommendation. High doses of Vitamin C supplements may interact with certain medications and medical conditions. |
| additional information | Vitamin C can be obtained from various fruits and vegetables. A balanced diet is the best approach. Storage of vitamin C in the body is limited. The body may only absorb a certain amount of Vitamin C at one time. High doses of Vitamin C may not provide additional benefits and may cause side effects. Avoid excessive intake without professional guidance. |
