Collagen Fit

£44.99 for 30 servings at Healf. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.

What it really costs, per 10 g£1.00One 10 g dose is our comparison unit for collagen. It is not a recommendation.
A day£1.00
A week£7.00
A month£29.99
A year£364.92

At one 10 g dose a day, this pack lasts 45 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Collagen

  • In the pack: 30 × 15 g = 450 g
  • £44.99 ÷ 450 g × 10 g = £1.00 per 10 g
  • A week £1.00 × 7 = £7.00 · a month × 30 = £29.99 · a year × 365 = £364.92
  • Amount per serving: stated on the label.

Betaine (TMG)

  • In the pack: 30 × 50 mg = 1.5 g
  • £44.99 ÷ 1.5 g × 2.5 g = £74.98 per 2.5 g
  • A week £74.98 × 7 = £524.88 · a month × 30 = £2249.50 · a year × 365 = £27368.92
  • Amount per serving: stated on the label.

Nicotinamide riboside

  • In the pack: 30 × 125 mg = 3.75 g
  • £44.99 ÷ 3.75 g × 300 mg = £3.60 per 300 mg
  • A week £3.60 × 7 = £25.19 · a month × 30 = £107.98 · a year × 365 = £1313.71
  • Amount per serving: stated on the label.
