Vitamin C

What is vitamin C?

Vitamin C is a water-soluble vitamin, also known as ascorbic acid. It is involved in normal collagen formation, acts as an antioxidant and helps the body absorb iron from plant foods.

Our range includes vitamin C-focused and combined nutrient liquids, as well as sodium ascorbate in an external swim-care spray. Understanding the form and purpose helps you find the right information for the product you are considering.

Vitamin C in everyday foods

Citrus fruits, kiwi fruit, strawberries, peppers and broccoli are familiar vitamin C sources. Amounts vary with the food, portion and preparation. Long storage and cooking can reduce vitamin C content.

A varied selection of fruit and vegetables brings different flavours and textures to meals. Fresh fruit on breakfast, vegetables with lunch and a colourful side at dinner are ordinary ways to build variety without organising meals around a single nutrient.

Ascorbic acid, ascorbates and liposomal formats

Ascorbic acid is one name you may see on a vitamin C ingredient panel. Mineral ascorbates, such as sodium ascorbate, are other forms. The complete formula determines how a finished product is intended to be used.

“Liposomal” describes a formulation approach involving lipids. It is separate from the vitamin C amount and the serving size. Use the nutrient panel to compare quantities rather than assuming every liposomal liquid has the same concentration.

Our dedicated vitamin C listing does not show a complete ingredient panel or name its exact vitamin C form. If you need those details before choosing, ask us for the current bottle information. The SwimFresh ingredient list explicitly names sodium ascorbate, but its external-use format is different from an oral supplement.

Vitamin C across our range

Reading a liquid vitamin C label

Start with the recommended serving, then look at how much vitamin C that serving provides. Millilitres measure liquid volume; milligrams measure the vitamin quantity. A 300 ml bottle contains more liquid than a 150 ml bottle, but bottle size alone does not establish strength.

Check whether a nutrient figure applies to one measured serving or the full daily amount. Use the measuring method specified on the label, and follow any instruction to shake before measuring.

With combined formulas, check each nutrient and the other ingredients as well as vitamin C. If you already use another supplement, compare both panels for overlap. Buying a bundle does not mean that the products have one shared serving instruction.

Keeping your routine straightforward

Follow the directions supplied with the exact formula you buy. Keep liquid supplement bottles tightly closed and away from direct sunlight and excessive heat. Check the label for any refrigeration or use-after-opening instructions rather than assuming every liquid is stored in the same way.

Keep the measuring equipment clean and retain the original label, batch information and best-before date. Store supplements out of reach of children.

Water-soluble does not mean unlimited amounts are suitable. Too much supplemental vitamin C can cause diarrhoea, nausea or stomach cramps. Follow the labelled serving; ask for individual advice if you have an iron-overload condition or are receiving medical treatment.

Keep external products such as SwimFresh with skin and hair care. Do not substitute an external spray for a nutritional vitamin C liquid.
