Magnesium Glycinate Capsules x 180, 180 capsules
£19.99 for 180 capsules at VitaBright. That works out at 7p per 100 mg magnesium, which ranks it 9th of the 66 magnesium bisglycinate products we price across 13 UK retailers.
At one 100 mg dose a day, this pack lasts 9 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 180 ÷ 2 per serving = 90
- In the pack: 90 × 300 mg = 27 g
- £19.99 ÷ 27 g × 100 mg = 7.4p per 100 mg magnesium
- A week 7.4p × 7 = 52p · a month × 30 = £2.22 · a year × 365 = £27.02
- Amount per serving: stated on the label.
