Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesise vitamin C endogenously, so it is an essential dietary component.
It is a nutrient your body needs to form blood vessels, cartilage, muscle and collagen in bones. Vitamin C is also vital to your body’s healing process.
Nutritional sources of Vitamin C are: citrus fruit, peppers, strawberries, blackcurrants, broccoli, brussels sprouts and potatoes. So if these foods don’t factor much in your dietary intake, it might be prudent to bring in a Vit C supplement to plug the gaps.
Who it’s for:
Ideal for anyone facing high training volume, travel, immune challenges, or dietary gaps – especially those wanting antioxidant protection or enhanced collagen support.
What it does:
Vitamin C supports collagen formation, immune cell function, antioxidant defense, iron absorption, and stress resilience. At higher doses, it can shorten the duration and reduce the severity of colds in stressed or exposed populations, and buffer oxidative damage from intense exercise. Think of it as pharmaceutical-grade nutrition insurance – especially for immune and recovery support.
How I would use it:
Take 1 g daily with food for maintenance; increase to 2 g split if under acute stress, travel, or during illness. Best divided doses to maintain blood levels and minimise digestive upset.
The Science:
Vitamin C reduces the severity of common colds, especially for severe cases
Study: Vitamin C reduces the severity of common colds: a meta-analysis.
BMC Public Health (2023)
A meta-analysis synthesising data from ten placebo-controlled trials (≥1g/day vitamin C). Vitamin C supplementation significantly reduced cold severity by 15%, with larger effects in more severe cold cases, although overall duration effects were more modest. Findings support its role in easing illness symptoms and reducing.
High-dose vitamin C reduces muscle damage and oxidative stress after intense exercise
Study: Short-term high-dose vitamin C and E supplementation attenuates muscle damage and inflammatory responses to repeated competition.
International Journal of Medical Sciences (2018)
In a randomised, double-blind trial of elite athletes (Taekwondo competitors), supplementation with 2,000mg/day vitamin C (plus vitamin E) for four days significantly lowered creatine kinase (−57.5%), myoglobin (−47%), and haemolysis (−40.5%) versus placebo, indicating reduced muscle damage and inflammation during repeated bouts.
