What people are saying
Several posts explore the biochemical role of vitamin C as an electron donor and enzyme cofactor, illustrating interest in its physiological functions. Others debate the effectiveness of high-dose supplements, referencing bioavailability data and encouraging focus on food sources, which demonstrates a balanced yet inquisitive engagement with the research findings.
Most discussions acknowledge the scientific information about vitamin C's biological functions, though some question its efficacy in high doses.
Participants show moderate interest, engaging in detailed explanations about bioavailability and dietary sources rather than superficial mentions.
Posts include technical details, references to research studies, and debates over supplement effectiveness, indicating meaningful involvement.
The discussions influence opinions on supplement usage and nutrition, but do not suggest a transformative shift in health practices or policies.
Abstract in brief
- Vitamin C (ascorbic acid) is an essential nutrient for humans and some primates because they cannot produce it themselves, so it must be obtained through diet.
- It acts as an electron donor and a cofactor for various enzymes, with its transport and levels in the body influenced by diet, absorption, and excretion, and understanding its physiological concentrations is key for research and clinical studies.
- The article reviews current knowledge about vitamin C’s roles, highlights areas where understanding is limited, and suggests future research directions to better understand its functions and importance.]

A1: When it comes to nutritional options to boost immunity – focus on food. Supplements have a role, but they’re not always utilised like the nutrients from food. 30mg Vitamin C from an orange is likely to be 100% absorbed. https://t.co/MicoAoSTKx #RDUK #immunity
A1: Bioavailability of vitamin C from supplements diminishes as dose increases. More isn’t better. That 1g #VitaminC supplement providing the equivalent of 4 litres of orange juice? Doesn’t pack a better immune punch https://t.co/MicoAoSTKx #RDUK #immunity
A1: When it comes to vitamin supplements, more ≠ better. A low dose of 30mg Vitamin C is totally absorbed. But as dose increases, bioavailability reduces, with plasma levels remaining constant at 200-250mg/d. https://t.co/5mg3vRRAbd #RDUK #immunity https://t.co/LdmZe7xrPf
