How we worked it out

Magnesium

  • Servings: 30 ÷ 2 per serving = 15
  • In the pack: 15 × 200 mg = 3 g
  • £12.79 ÷ 3 g × 100 mg = 42.6p per 100 mg magnesium
  • A week 42.6p × 7 = £2.98 · a month × 30 = £12.79 · a year × 365 = £155.61
  • Amount per serving: stated on the label.

Folate

  • Servings: 30 ÷ 2 per serving = 15
  • In the pack: 15 × 200 µg = 3 mg
  • £12.79 ÷ 3 mg × 400 µg = £1.71 per 400 µg
  • A week £1.71 × 7 = £11.94 · a month × 30 = £51.16 · a year × 365 = £622.45
  • Amount per serving: stated on the label.

Taurine

  • Servings: 30 ÷ 2 per serving = 15
  • In the pack: 15 × 300 mg = 4.5 g
  • £12.79 ÷ 4.5 g × 1 g = £2.84 per 1 g
  • A week £2.84 × 7 = £19.90 · a month × 30 = £85.27 · a year × 365 = £1037.41
  • Amount per serving: stated on the label.

Vitamin B12

  • Servings: 30 ÷ 2 per serving = 15
  • In the pack: 15 × 25 µg = 375 µg
  • £12.79 ÷ 375 µg × 1 mg = £34.11 per 1 mg
  • A week £34.11 × 7 = £238.75 · a month × 30 = £1023.20 · a year × 365 = £12448.93
  • Amount per serving: stated on the label.

Vitamin B6

  • Servings: 30 ÷ 2 per serving = 15
