How we worked it out
- Servings: 120 ÷ 2 per serving = 60
- In the pack: 60 × 1.5 g = 90 g
- £12.99 ÷ 90 g × 100 mg = 1.44p per 100 mg bisglycinate (glycinate)
- A week 1.44p × 7 = 10p · a month × 30 = 43p · a year × 365 = £5.27
- Amount per serving: estimated from the compound weight using our conversion factor.
