How we worked it out
Folate
- Servings: 250 ÷ 1 per serving = 250
- In the pack: 250 × 800 µg = 200 mg
- £5.73 ÷ 200 mg × 400 µg = 1.15p per 400 µg
- A week 1.15p × 7 = 8p · a month × 30 = 34p · a year × 365 = £4.18
- Amount per serving: stated on the label.
Vitamin B12
- Servings: 250 ÷ 1 per serving = 250
- In the pack: 250 × 25 µg = 6.25 mg
- £5.73 ÷ 6.25 mg × 1 mg = 91.7p per 1 mg
- A week 91.7p × 7 = £6.42 · a month × 30 = £27.50 · a year × 365 = £334.63
- Amount per serving: stated on the label.
