Whey Protein Isolate, Vanilla, 837 g
£51.13 for 837 g at Healf. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.
At one 25 g dose a day, this pack lasts 25 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 837 ÷ 27.9 per serving = 30
- In the pack: 30 × 21 g = 630 g
- £51.13 ÷ 630 g × 25 g = £2.03 per 25 g protein
- A week £2.03 × 7 = £14.20 · a month × 30 = £60.87 · a year × 365 = £740.57
- Amount per serving: stated on the label.
