A family member has been taking Vitamin C supplements, but is now wondering if he should continue to spend money on these supplements. What have you learned about Vitamin C that might help them with an evidence-based decision?

Based on what has been learned about vitamin C, an evidence-based argument that can be used to support the family member's choice of whether to continue taking vitamin C is the adverse effects on the digestive system - diarrhea, pain abdominal- and drug interaction, such as increased estrogens or inhibition of anticoagulant effect.

Explanation:

Vitamin C belongs to the group of water-soluble vitamins and is important for the maintenance of health because of its antioxidant properties. It is also used in the prevention of viral infections.

The daily dose, according to the requirements of an adult, of vitamin C should be 100 mg, with a maximum dose around 1500 and 2000 mg/day.

Research has documented that excessive consumption of Vitamin C can cause undesirable effects such as

Abdominal pain or cramps.
Diarrhea.
Nausea and vomiting.
Headache and insomnia.

Additionally, this vitamin can produce drug interactions, such as a reduction in the effect of anticoagulants, increased estrogen levels in women, or interference with antiviral medications.

The above is a valid, evidence-based argument for a person refusing to take vitamin C supplements.
