Impact Micellar Casein Powder, Hokkaido Milk, 1 kg
£28.99 for 1 kg at Myprotein. That works out at 91p per 25 g protein, which ranks it 1st of the 17 casein protein products we price across 3 UK retailers.
At one 25 g dose a day, this pack lasts 32 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 1000 ÷ 30 per serving = 33.3
- In the pack: 33.3 × 24 g = 800 g
- £28.99 ÷ 800 g × 25 g = 90.6p per 25 g protein
- A week 90.6p × 7 = £6.34 · a month × 30 = £27.18 · a year × 365 = £330.67
- Amount per serving: stated on the label.
