New developments and novel therapeutic perspectives for vitamin C

Area of Science:

• Nutritional biochemistry
• Biomedical science
• Oxidative stress research

Background:

• Vitamin C (ascorbic acid) is essential for collagen synthesis and hormone biosynthesis.
• Recommended dietary intakes are based on these functions, not its antioxidant role.
• Physiological availability is limited by instability, poor absorption, and rapid excretion.

Purpose of the Study:

• To review recent studies on vitamin C transport mechanisms and clinical implications.
• To evaluate evidence for high-dose vitamin C therapy in cancer and cardiovascular disease (CVD).
• To explore mechanisms of action and potential therapeutic applications of vitamin C.

Main Methods:

• Review of recent scientific literature on vitamin C.
• Analysis of clinical studies and evidence regarding vitamin C's effects on cancer and CVD.
• Discussion of animal models for vitamin C therapy research.

Main Results:

• Inability to maintain high serum vitamin C levels may link to degenerative diseases.
• Oxidative damage is a significant factor in cancer and CVD.
• Emerging evidence suggests potential therapeutic roles for high-dose vitamin C.

Conclusions:

• Understanding vitamin C transport and bioavailability is critical for health.
• High-dose vitamin C therapy warrants further investigation for cancer and CVD.
• Further research, including animal models, is needed to clarify vitamin C's therapeutic potential.
