Vitamins A-D-K, 30 softgels

£42.45 for 30 softgels 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 800 µg£1.26One 800 µg dose is our comparison unit for vitamin A. It is not a recommendation.
A day£1.26
A week£8.80
A month£37.73
A year£459.09

At one 800 µg dose a day, this pack lasts 34 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Vitamin A

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 900 µg = 27 mg
  • £42.45 ÷ 27 mg × 800 µg = £1.26 per 800 µg
  • A week £1.26 × 7 = £8.80 · a month × 30 = £37.73 · a year × 365 = £459.09
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 5,000 IU = 150,000 IU
  • £42.45 ÷ 150,000 IU × 1,000 IU = 28.3p per 1,000 IU
  • A week 28.3p × 7 = £1.98 · a month × 30 = £8.49 · a year × 365 = £103.29
  • Amount per serving: stated on the label.

Vitamin K1

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 1 mg = 30 mg
  • £42.45 ÷ 30 mg × 100 µg = 14.2p per 100 µg
  • A week 14.2p × 7 = 99p · a month × 30 = £4.25 · a year × 365 = £51.65
  • Amount per serving: stated on the label.

Vitamin K2

  • Servings: 30 ÷ 1 per serving = 30
  • In the pack: 30 × 300 µg = 9 mg
  • £42.45 ÷ 9 mg × 100 µg = 47.2p per 100 µg
  • A week 47.2p × 7 = £3.30 · a month × 30 = £14.15 · a year × 365 = £172.16
  • Amount per serving: stated on the label.
