Hydrolysed collagen
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
Collagen hydrolysate, also called collagen peptides: a mixture of shorter protein chains. [1] [2]
Natural origin
Animal connective tissues; commercial sources include cattle, pigs and fish. These sources are not interchangeable for dietary preferences or allergen assessment. [1] [2]
History & background
Collagen processing developed from the production of gelatin into more extensively hydrolysed, soluble ingredients. [1] [2]
Production methods
Extraction and controlled hydrolysis break down protein chains; filtration and drying produce a powder. Enzymes and processing conditions affect the resulting peptide mixture. [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
Its amino-acid pattern differs from milk protein, with substantial glycine and proline. A collagen portion should not be assumed nutritionally equivalent to a whey portion. [1] [2]
Food & sports nutrition
Read the complete formula: collagen powder may contain carbohydrates, vitamins and other substances in addition to collagen. [1] [2]
Research & limitations
Studies use different peptide preparations, doses and populations. Their results cannot establish effects of this FitGirl blend. No authorised EU health claim exists for collagen itself. [1] [2]
Approved health claims
No authorised EU health claim exists for collagen itself. Vitamin C is listed on the available labels, but no positive vitamin or mineral claim is activated on this multi-ingredient product page while its composition, energy and complete allergen declaration require reconciliation. A vitamin C claim must never be presented as a collagen benefit. [3] [4] [5]
