B Minus, 100 capsules

A day88p
A week£6.16

At one 100 mg dose a day, this pack lasts 25 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Thiamine (vitamin B1)

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 25 mg = 2.5 g
  • £21.99 ÷ 2.5 g × 100 mg = 88p per 100 mg
  • A week 88p × 7 = £6.16 · a month × 30 = £26.39 · a year × 365 = £321.05
  • Amount per serving: stated on the label.

Biotin

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 500 µg = 50 mg
  • £21.99 ÷ 50 mg × 5 mg = £2.20 per 5 mg
  • A week £2.20 × 7 = £15.39 · a month × 30 = £65.97 · a year × 365 = £802.64
  • Amount per serving: stated on the label.

Pantothenic acid (B5)

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 150 mg = 15 g
  • £21.99 ÷ 15 g × 500 mg = 73.3p per 500 mg
  • A week 73.3p × 7 = £5.13 · a month × 30 = £21.99 · a year × 365 = £267.54
  • Amount per serving: stated on the label.

Riboflavin (vitamin B2)

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 20 mg = 2 g
  • £21.99 ÷ 2 g × 100 mg = £1.10 per 100 mg
  • A week £1.10 × 7 = £7.70 · a month × 30 = £32.99 · a year × 365 = £401.32
  • Amount per serving: stated on the label.

Vitamin B6

  • Servings: 100 ÷ 1 per serving = 100
  • In the pack: 100 × 20 mg = 2 g
