A day£9.89
A week£69.21

A year£3609.04

At one 1 g dose a day, this pack lasts 9 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Vitamin C

  • Servings: 180 ÷ 6 per serving = 30
  • In the pack: 30 × 300 mg = 9 g
  • £88.99 ÷ 9 g × 1 g = £9.89 per 1 g
  • A week £9.89 × 7 = £69.21 · a month × 30 = £296.63 · a year × 365 = £3609.04
  • Amount per serving: stated on the label.

Folate

  • Servings: 180 ÷ 6 per serving = 30
  • In the pack: 30 × 200 µg = 6 mg
  • £88.99 ÷ 6 mg × 400 µg = £5.93 per 400 µg
  • A week £5.93 × 7 = £41.53 · a month × 30 = £177.98 · a year × 365 = £2165.42
  • Amount per serving: stated on the label.

Iodine

  • Servings: 180 ÷ 6 per serving = 30
  • In the pack: 30 × 75 µg = 2.25 mg
  • £88.99 ÷ 2.25 mg × 150 µg = £5.93 per 150 µg iodine
  • A week £5.93 × 7 = £41.53 · a month × 30 = £177.98 · a year × 365 = £2165.42
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 180 ÷ 6 per serving = 30
  • In the pack: 30 × 50 mg = 1.5 g
  • £88.99 ÷ 1.5 g × 100 mg = £5.93 per 100 mg magnesium
  • A week £5.93 × 7 = £41.53 · a month × 30 = £177.98 · a year × 365 = £2165.42
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 180 ÷ 6 per serving = 30
  • In the pack: 30 × 500 IU = 15,000 IU
  • £88.99 ÷ 15,000 IU × 1,000 IU = £5.93 per 1,000 IU
  • A week £5.93 × 7 = £41.53 · a month × 30 = £177.98 · a year × 365 = £2165.42
  • Amount per serving: stated on the label.

Zinc

  • Servings: 180 ÷ 6 per serving = 30
  • In the pack: 30 × 7.5 mg = 225 mg
  • £88.99 ÷ 225 mg × 15 mg = £5.93 per 15 mg zinc
  • A week £5.93 × 7 = £41.53 · a month × 30 = £177.98 · a year × 365 = £2165.42
  • Amount per serving: stated on the label.
