ZMA, 120 capsules
£21.99 for 120 capsules at Bio-Synergy. That works out at 24p per 15 mg zinc, which ranks it 16th of the 25 other forms of zinc products we price across 8 UK retailers.
At one 15 mg 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: 120 ÷ 1 per serving = 120
- In the pack: 120 × 11.6 mg = 1.4 g
- £21.99 ÷ 1.4 g × 15 mg = 23.6p per 15 mg zinc
- A week 23.6p × 7 = £1.65 · a month × 30 = £7.09 · a year × 365 = £86.27
- Amount per serving: stated on the label.
