Manganese · diglycinate
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
An essential trace mineral; diglycinate names the declared compound form. [1] [2]
Natural origin
Manganese occurs in foods including grains and nuts. A mineral compound in a supplement is not evidence of extraction from those foods. [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
Manufacturing requires a specified mineral compound and purity control. FitGirl’s supplier method and certificate are 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
Read elemental manganese, not total diglycinate weight. The EU adult label reference is 2 mg, not a maximum intake. [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]
