1000mg Magnesium Bisglycinate Tablets, 90 tablets
£9.99 for 90 tablets at Myprotein. That works out at 10p per 100 mg magnesium, which ranks it 15th of the 66 magnesium bisglycinate products we price across 13 UK retailers.
At one 100 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: 90 ÷ 1 per serving = 90
- In the pack: 90 × 112.5 mg = 10.1 g
- £9.99 ÷ 10.1 g × 100 mg = 9.87p per 100 mg magnesium
- A week 9.87p × 7 = 69p · a month × 30 = £2.96 · a year × 365 = £36.01
- Amount per serving: stated on the label.
