How we worked it out
- Servings: 90 ÷ 1 per serving = 90
- In the pack: 90 × 700 mg = 63 g
- £20.24 ÷ 63 g × 100 mg = 3.21p per 100 mg bisglycinate (glycinate)
- A week 3.21p × 7 = 22p · a month × 30 = 96p · a year × 365 = £11.73
- Amount per serving: estimated from the compound weight using our conversion factor.
