Vitamin C 500mg, 90 capsules
£17.97 for 90 capsules at Healf. That works out at 40p per 1 g, which ranks it 62nd of the 113 vitamin C products we price across 21 UK retailers.
At one 1 g dose a day, this pack lasts 45 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 90 ÷ 1 per serving = 90
- In the pack: 90 × 500 mg = 45 g
- £17.97 ÷ 45 g × 1 g = 39.9p per 1 g
- A week 39.9p × 7 = £2.80 · a month × 30 = £11.98 · a year × 365 = £145.76
- Amount per serving: stated on the label.
