Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Vitamin C has long been associated with general health and vitality, and its use in treating or supporting "debility"—a nonspecific term referring to general weakness or lack of strength—has roots in traditional medicine. Historically, vitamin C-rich foods and supplements were prescribed to individuals suffering from fatigue, convalescence after illness, or chronic weakness, due to its well-known role in preventing and treating scurvy, a disease marked by profound fatigue, weakness, anemia, and connective tissue defects. The dramatic improvement seen in scurvy patients after vitamin C administration may have contributed to the perception that vitamin C could help with other forms of debility.

However, scientific validation for vitamin C supplementation in treating nonspecific debility in otherwise healthy individuals is limited. While vitamin C is an essential nutrient and deficiency can lead to significant symptoms, in people with adequate intake, supplementation does not consistently improve energy levels or treat fatigue not linked to vitamin C deficiency. Some studies have explored vitamin C for its potential to reduce fatigue in specific contexts (such as after surgery or in chronic illnesses), but the evidence is mixed and generally not strong enough to support routine use for debility. Thus, the justification for vitamin C in this context is primarily traditional, with a modest evidence rating reflecting its historical use and possible benefit in deficiency states rather than robust scientific support for general debility.
