FITGIRL / Ingredient library
Calcium carbonate
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. [4]
Identity & classification
CaCO3, a calcium salt. Calcium content and total carbonate mass are not the same. [1] [2]
Natural origin
Occurs in mineral deposits and biological shells. The chemical name does not identify the commercial source. [1] [2]
History & background
The modern ingredient name distinguishes a defined substance or preparation from its source material. The cited specification or technical source documents this distinction; no historical use of the FitGirl formula is implied. [1] [2]
Production methods
Food-grade carbonate is obtained and purified to specification; the FitGirl extraction or precipitation route is unverified. [1] [2]
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
A mineral source in the formula. Read the declared elemental calcium amount, not the mass of calcium carbonate. [1] [2]
Food & sports nutrition
Read its role alongside the complete product composition. A technological ingredient or an unquantified component is not a separate sports-nutrition recommendation. [1] [2]
Research & limitations
The sources describe ingredient identity and composition. They do not test this FitGirl formula. Dose, preparation, study population and outcome must match before research can be interpreted for a particular product; legal authorisation is a separate requirement. [1] [2]
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] [4] [5]
