L Arginine, 100 g
£3.99 for 100 g at Bulk. That works out at 12p per 3 g, which ranks it 12th of the 12 L-Arginine products we price across 7 UK retailers.
At one 3 g dose a day, this pack lasts 33 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 100 ÷ 3 per serving = 33.3
- In the pack: 33.3 × 3 g = 100 g
- £3.99 ÷ 100 g × 3 g = 12p per 3 g
- A week 12p × 7 = 84p · a month × 30 = £3.59 · a year × 365 = £43.69
- Amount per serving: stated on the label.
