£36.87 for 500 g at Vitamin Planet. That works out at 37p per 5 g, which ranks it 9th of the 29 L-glutamine products we price across 9 UK retailers.
At one 5 g dose a day, this pack lasts 3 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 500 ÷ 5 per serving = 100
- In the pack: 100 × 5 g = 500 g
- £36.87 ÷ 500 g × 5 g = 36.9p per 5 g
- A week 36.9p × 7 = £2.58 · a month × 30 = £11.06 · a year × 365 = £134.58
- Amount per serving: stated on the label.
