Vitamin C · L-ascorbic acid
Content reviewed:
Ingredient information is not a product efficacy study. A publication, traditional use or a link to an ingredient does not authorise a health claim. [5]
Identity & classification
L-ascorbic acid is a water-soluble vitamin. The chemical name identifies the compound, not the plant or country used to make it. [1] [2] [3] [4]
Natural origin
Fruit and vegetables are dietary sources. Added L-ascorbic acid need not have been extracted from fruit. [1] [2] [3] [4]
History & background
Identification of vitamin C separated the nutrient itself from the foods that supply it. Modern labels specify a measured vitamin quantity. [1] [2] [3] [4]
Production methods
Food-grade ascorbic acid is purified to a defined specification. The starting material, fermentation route and factory used for FitGirl have not been verified. [1] [2] [3] [4]
FitGirl raw material: the supplier, country of origin, batch specification and manufacturing process have not been independently verified. General production methods below do not establish the origin of this product.
Nutritional properties
Compare the declared vitamin quantity with the total from food and other supplements. The EU adult label reference value is 80 mg; a reference value is not a maximum safe intake. [1] [2] [3] [4]
Food & sports nutrition
In a blend, vitamin C remains a separate nutrient. A claim for vitamin C cannot be reassigned to collagen or to every ingredient in the blend. [1] [2] [3] [4]
Research & limitations
Physiological knowledge about a vitamin is not a trial of a multi-ingredient supplement. Only a specifically authorised claim with all conditions met may be used commercially. [1] [2] [3] [4]
Approved health claims
Authorised claims exist for this nutrient, but they require at least the applicable “source of” quantity and all accompanying conditions. Chemical form, declared nutrient amount, preparation and the specific claim must be checked. No benefit wording is used here or transferred to other ingredients in a blend. [3] [5] [6]
