MSM Powder, 500 g
£12.99 for 500 g at Bulk. That works out at 3p per 1 g, which ranks it 3rd of the 14 MSM products we price across 8 UK retailers.
At one 1 g dose a day, this pack lasts 1.4 years. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 500 ÷ 1.6 per serving = 312.5
- In the pack: 312.5 × 1.6 g = 500 g
- £12.99 ÷ 500 g × 1 g = 2.6p per 1 g
- A week 2.6p × 7 = 18p · a month × 30 = 78p · a year × 365 = £9.48
- Amount per serving: stated on the label.
