Marine Collagen With Magnesium Capsules
£16.99 for 40 servings at WeightWorld. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.
At one 10 g dose a day, this pack lasts 5 days. A month is 30 days, so twelve of them is not quite a year.
