How we worked it out

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 37.5 mg = 1.13 g
  • £24.48 ÷ 1.13 g × 100 mg = £2.18 per 100 mg
  • A week £2.18 × 7 = £15.23 · a month × 30 = £65.28 · a year × 365 = £794.24
  • Amount per serving: stated on the label.

Inositol

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 50 mg = 1.5 g
  • £24.48 ÷ 1.5 g × 2 g = £32.64 per 2 g
  • A week £32.64 × 7 = £228.48 · a month × 30 = £979.20 · a year × 365 = £11913.60
  • Amount per serving: stated on the label.

Pantothenic acid (B5)

  • Servings: 30 ÷ 1 per serving = 30
