Daily Fiber Powder Tub, Strawberry Lemonade, 181 g

£22.99 for 181 g 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£7.18One 10 g dose is our comparison unit for collagen. It is not a recommendation.
A day£7.18
A week£50.24

At one 10 g dose a day, this pack lasts 3 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Collagen

  • Servings: 181 ÷ 11.3 per serving = 16
  • In the pack: 16 × 2 g = 32 g
  • £22.99 ÷ 32 g × 10 g = £7.18 per 10 g
  • A week £7.18 × 7 = £50.24 · a month × 30 = £215.29 · a year × 365 = £2619.40
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 181 ÷ 11.3 per serving = 16
  • In the pack: 16 × 75 mg = 1.2 g
  • £22.99 ÷ 1.2 g × 100 mg = £1.91 per 100 mg magnesium
  • A week £1.91 × 7 = £13.40 · a month × 30 = £57.41 · a year × 365 = £698.51
  • Amount per serving: stated on the label.

Niacin (vitamin B3)

  • Servings: 181 ÷ 11.3 per serving = 16
  • In the pack: 16 × 7.5 mg = 120.1 mg
  • £22.99 ÷ 120.1 mg × 500 mg = £95.69 per 500 mg
  • A week £95.69 × 7 = £669.80 · a month × 30 = £2870.57 · a year × 365 = £34925.32
  • Amount per serving: stated on the label.

Potassium

  • Servings: 181 ÷ 11.3 per serving = 16
  • In the pack: 16 × 100 mg = 1.6 g
  • £22.99 ÷ 1.6 g × 200 mg = £2.87 per 200 mg potassium
  • A week £2.87 × 7 = £20.09 · a month × 30 = £86.12 · a year × 365 = £1047.76
