When vitamin C runs low, its impact isn’t just skin‑deep, it can also affect the heart and lungs, sometimes contributing to shortness of breath, fatigue, and fluid retention. Severe vitamin C deficiency has been reported as a reversible cause of pulmonary hypertension and right‑sided heart failure, with pressures in the lung circulation and cardiac strain improving after vitamin C is replaced. Broader cardiovascular research also links low vitamin C with higher blood pressure and stiffer arteries, while short‑term supplementation in some hypertensive or diabetic patients has lowered systolic blood pressure and improved arterial stiffness, suggesting that adequate vitamin C helps support healthier vascular tone and cardiac workload. This medication is commonly used for High Cholesterol.

Some side effects may be linked to nutrient depletion caused by this medication.
Fenofibrate has been shown in studies to increase the toxic effect of ultraviolet (UV) radiation that may lead to side effects such as hives, itching, and skin rash. Taking vitamin E before UV exposure is found in research to significantly help block UV-fenofibrate effects on the skin. Vitamin E supplementation should be considered when taking this drug therapy.

Research demonstrates that fibrates, particularly fenofibrate, are known to increase homocysteine levels. Elevated levels of homocysteine is associated with increased risk of a range of health problems including atherosclerosis, stroke, and neurological diseases, and vitamin Bs including vitamin B6 helps facilitate the breakdown of homocysteine and may be helpful in reducing homocysteine levels.
