How we worked it out
Vitamin D3
- Servings: 30 ÷ 1 per serving = 30
- In the pack: 30 × 800 IU = 24,000 IU
- £21.39 ÷ 24,000 IU × 1,000 IU = 89.1p per 1,000 IU
- A week 89.1p × 7 = £6.24 · a month × 30 = £26.74 · a year × 365 = £325.31
- Amount per serving: stated on the label.
Vitamin K2
- Servings: 30 ÷ 1 per serving = 30
- In the pack: 30 × 80 µg = 2.4 mg
- £21.39 ÷ 2.4 mg × 100 µg = 89.1p per 100 µg
- A week 89.1p × 7 = £6.24 · a month × 30 = £26.74 · a year × 365 = £325.31
