How we worked it out

Collagen

  • Servings: 300 ÷ 5 per serving = 60
  • In the pack: 60 × 5 g = 300 g
  • £45.00 ÷ 300 g × 10 g = £1.50 per 10 g
  • A week £1.50 × 7 = £10.50 · a month × 30 = £45.00 · a year × 365 = £547.50
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 300 ÷ 5 per serving = 60
  • In the pack: 60 × 50 mg = 3 g
  • £45.00 ÷ 3 g × 1 g = £15.00 per 1 g
  • A week £15.00 × 7 = £105.00 · a month × 30 = £450.00 · a year × 365 = £5475.00
  • Amount per serving: stated on the label.

Ingredients

Pure marine codfish (Gadus Morhua) collagen peptides, acerola (natural Vitamin C source), natural strawberry & rhubarb flavour, acid (malic acid), colouring (maltodextrin, beetroot extract E162), sweetener (steviol glycosides E960). The important amino acids glycine, proline and hydroxyproline are the most prevalent in collagen peptides, making up 50 per cent of its total amino acid content - the same amount that's in human skin. Collagen can affect serotonin levels.
