Why Vitamin C Appears

Several daily-hydration brands include vitamin C in their formulations - Liquid I.V., Nuun's Immunity variant, and many others. The marketing emphasis is on "immune support," though the evidence on vitamin C supplementation specifically supporting immunity in well-fed adults is more nuanced than the marketing suggests.

Daily Intake Picture

Australian dietary guidance suggests adults get around 45 mg of vitamin C per day - easily achieved through a piece of fruit, a salad, or any normal Australian diet. Electrolyte products that include vitamin C typically deliver 30-100 mg per serve, which is meaningful but not transformative if your diet is otherwise reasonable.

Real Use Cases

For travel days, festival days, or stretches where eating is genuinely thin, the added vitamin C is a small benefit. For daily desk hydration on a normal day, it's a marketing detail.

Not the Reason to Pick a Product

Vitamin C content shouldn't drive electrolyte product choice. The big variable remains sodium. If two otherwise-similar products differ only in vitamin C content, that's a small tiebreaker rather than a meaningful difference.

Frequently Asked

Why do some electrolyte products include vitamin C?

Brands often add it for marketing positioning around 'immune support' framing. The dose is meaningful but not transformative for adults with reasonable diets.

Do I need vitamin C in my hydration drink?

Not generally. A normal Australian diet covers daily vitamin C needs through fruit and vegetables. Travel days or illness recovery contexts can be exceptions.

How much vitamin C is too much?

Australian guidance puts the upper limit around 1,000 mg/day for adults. Typical electrolyte products deliver well under that.
