MSM Powder, 1 kg
£24.99 for 1 kg at Bulk. That works out at 2p per 1 g, which ranks it 2nd of the 14 MSM products we price across 8 UK retailers.
At one 1 g dose a day, this pack lasts 2.7 years. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 1000 ÷ 1.6 per serving = 625
- In the pack: 625 × 1.6 g = 1,000 g
- £24.99 ÷ 1,000 g × 1 g = 2.5p per 1 g
- A week 2.5p × 7 = 17p · a month × 30 = 75p · a year × 365 = £9.12
- Amount per serving: stated on the label.
