At one 1 g dose a day, this pack lasts 4 months. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Servings: 180 ÷ 2 per serving = 90
In the pack: 90 × 1.2 g = 108 g
£13.99 ÷ 108 g × 1 g = 13p per 1 g
A week 13p × 7 = 91p · a month × 30 = £3.89 · a year × 365 = £47.28
