A day£1.11
A week£7.78

How we worked it out

Caffeine

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 60 mg = 5.4 g
  • £29.99 ÷ 5.4 g × 200 mg = £1.11 per 200 mg
  • A week £1.11 × 7 = £7.78 · a month × 30 = £33.32 · a year × 365 = £405.42
  • Amount per serving: stated on the label.

Alpha-lipoic acid

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 260 mg = 23.4 g
  • £29.99 ÷ 23.4 g × 300 mg = 38.4p per 300 mg
  • A week 38.4p × 7 = £2.69 · a month × 30 = £11.53 · a year × 365 = £140.34
  • Amount per serving: stated on the label.

Chromium

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 200 µg = 18 mg
  • £29.99 ÷ 18 mg × 200 µg = 33.3p per 200 µg chromium
  • A week 33.3p × 7 = £2.33 · a month × 30 = £10.00 · a year × 365 = £121.63
  • Amount per serving: stated on the label.

Green coffee bean extract

  • Servings: 90 ÷ 1 per serving = 90
  • In the pack: 90 × 250 mg = 22.5 g
  • £29.99 ÷ 22.5 g × 400 mg = 53.3p per 400 mg
  • A week 53.3p × 7 = £3.73 · a month × 30 = £15.99 · a year × 365 = £194.60
