How we worked it out

Collagen

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 5 g = 60 g
  • £14.99 ÷ 60 g × 10 g = £2.50 per 10 g
  • A week £2.50 × 7 = £17.49 · a month × 30 = £74.95 · a year × 365 = £911.89
  • Amount per serving: stated on the label.

Biotin

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 50 µg = 600 µg
  • £14.99 ÷ 600 µg × 5 mg = £124.92 per 5 mg
  • A week £124.92 × 7 = £874.42 · a month × 30 = £3747.50 · a year × 365 = £45594.58
  • Amount per serving: stated on the label.

Hyaluronic acid

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 25 mg = 300 mg
  • £14.99 ÷ 300 mg × 100 mg = £5.00 per 100 mg
  • A week £5.00 × 7 = £34.98 · a month × 30 = £149.90 · a year × 365 = £1823.78
  • Amount per serving: stated on the label.

Niacin (vitamin B3)

  • Servings: 12 ÷ 1 per serving = 12
  • In the pack: 12 × 8 mg = 96 mg
  • £14.99 ÷ 96 mg × 500 mg = £78.07 per 500 mg
  • A week £78.07 × 7 = £546.51 · a month × 30 = £2342.19 · a year × 365 = £28496.61
