TMG
£19.69 for 120 servings at Healf. That works out at 55p per 2.5 g, which ranks it 4th of the 7 betaine anhydrous products we price across 1 UK retailer.
At one 2.5 g dose a day, this pack lasts 36 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- In the pack: 120 × 750 mg = 90 g
- £19.69 ÷ 90 g × 2.5 g = 54.7p per 2.5 g
- A week 54.7p × 7 = £3.83 · a month × 30 = £16.41 · a year × 365 = £199.63
