What it really costs, per 400 µg40pOne 400 µg dose is our comparison unit for folate. It is not a recommendation.
A day40p
A week£2.80
A month£12.01
A year£146.10

At one 400 µg dose a day, this pack lasts 2 months. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Folate

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 1 mg = 30 mg
  • £30.02 ÷ 30 mg × 400 µg = 40p per 400 µg
  • A week 40p × 7 = £2.80 · a month × 30 = £12.01 · a year × 365 = £146.10
  • Amount per serving: stated on the label.

Iron

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 45 mg = 1.35 g
  • £30.02 ÷ 1.35 g × 14 mg = 31.1p per 14 mg iron
  • A week 31.1p × 7 = £2.18 · a month × 30 = £9.34 · a year × 365 = £113.63
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 90 mg = 2.7 g
  • £30.02 ÷ 2.7 g × 100 mg = £1.11 per 100 mg magnesium
  • A week £1.11 × 7 = £7.78 · a month × 30 = £33.36 · a year × 365 = £405.83
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 150 mg = 4.5 g
  • £30.02 ÷ 4.5 g × 1 g = £6.67 per 1 g
  • A week £6.67 × 7 = £46.70 · a month × 30 = £200.13 · a year × 365 = £2434.96
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 1,000 IU = 30,000 IU
  • £30.02 ÷ 30,000 IU × 1,000 IU = £1.00 per 1,000 IU
  • A week £1.00 × 7 = £7.00 · a month × 30 = £30.02 · a year × 365 = £365.24
  • Amount per serving: stated on the label.

Vitamin E

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 33.5 mg = 1.01 g
  • £30.02 ÷ 1.01 g × 268 mg = £8.01 per 268 mg
  • A week £8.01 × 7 = £56.04 · a month × 30 = £240.16 · a year × 365 = £2921.95
  • Amount per serving: stated on the label.
