How we worked it out

Chromium

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 50 µg = 6 mg
  • £22.90 ÷ 6 mg × 200 µg = 76.3p per 200 µg chromium
  • A week 76.3p × 7 = £5.34 · a month × 30 = £22.90 · a year × 365 = £278.62
  • Amount per serving: stated on the label.

Berberine

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 200 mg = 24 g
  • £22.90 ÷ 24 g × 500 mg = 47.7p per 500 mg
  • A week 47.7p × 7 = £3.34 · a month × 30 = £14.31 · a year × 365 = £174.14
  • Amount per serving: stated on the label.

Inositol

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 125 mg = 15 g
  • £22.90 ÷ 15 g × 2 g = £3.05 per 2 g
  • A week £3.05 × 7 = £21.37 · a month × 30 = £91.60 · a year × 365 = £1114.47
  • Amount per serving: stated on the label.

N-Acetyl Cysteine

  • Servings: 120 ÷ 1 per serving = 120
  • In the pack: 120 × 175 mg = 21 g
  • £22.90 ÷ 21 g × 600 mg = 65.4p per 600 mg
  • A week 65.4p × 7 = £4.58 · a month × 30 = £19.63 · a year × 365 = £238.88
  • Amount per serving: stated on the label.
