Magnesium Glycinate, 120 tablets
£14.99 for 120 tablets at Healf. That works out at 12p per 100 mg magnesium, which ranks it 19th of the 66 magnesium bisglycinate products we price across 13 UK retailers.
At one 100 mg dose a day, this pack lasts 4 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 120 ÷ 2 per serving = 60
- In the pack: 60 × 200 mg = 12 g
- £14.99 ÷ 12 g × 100 mg = 12.5p per 100 mg magnesium
- A week 12.5p × 7 = 87p · a month × 30 = £3.75 · a year × 365 = £45.59
- Amount per serving: stated on the label.
