L-Glutamine Powder, Unflavoured, 513 g
£52.45 for 513 g at Healf. That works out at 57p per 5 g, which ranks it 12th 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: 513 ÷ 5.6 per serving = 91.6
- In the pack: 91.6 × 5 g = 458 g
- £52.45 ÷ 458 g × 5 g = 57.3p per 5 g
- A week 57.3p × 7 = £4.01 · a month × 30 = £17.18 · a year × 365 = £208.98
- Amount per serving: stated on the label.
