Ultimate 8 Glutathione, 120 capsules

£25.99 for 120 capsules 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.

A day22p
A week£1.52
A month£6.50
A year£79.05

At one 250 mg dose a day, this pack lasts 4 months. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Glutathione

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 500 mg = 30 g
  • £25.99 ÷ 30 g × 250 mg = 21.7p per 250 mg
  • A week 21.7p × 7 = £1.52 · a month × 30 = £6.50 · a year × 365 = £79.05
  • Amount per serving: stated on the label.

Alpha-lipoic acid

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 100 mg = 6 g
  • £25.99 ÷ 6 g × 300 mg = £1.30 per 300 mg
  • A week £1.30 × 7 = £9.10 · a month × 30 = £38.99 · a year × 365 = £474.32
  • Amount per serving: stated on the label.

Black pepper (piperine)

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 5 mg = 300 mg
  • £25.99 ÷ 300 mg × 5 mg = 43.3p per 5 mg
  • A week 43.3p × 7 = £3.03 · a month × 30 = £13.00 · a year × 365 = £158.11
  • Amount per serving: extract weight stated on the label.

N-Acetyl Cysteine

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 150 mg = 9 g
  • £25.99 ÷ 9 g × 600 mg = £1.73 per 600 mg
  • A week £1.73 × 7 = £12.13 · a month × 30 = £51.98 · a year × 365 = £632.42
  • Amount per serving: stated on the label.

Selenium

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 200 µg = 12 mg
  • £25.99 ÷ 12 mg × 100 µg = 21.7p per 100 µg selenium
  • A week 21.7p × 7 = £1.52 · a month × 30 = £6.50 · a year × 365 = £79.05
  • Amount per serving: stated on the label.

Vitamin C

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 100 mg = 6 g

  • A week £4.33 × 7 = £30.32 · a month × 30 = £129.95 · a year × 365 = £1581.06
  • Amount per serving: stated on the label.

Vitamin E

  • Servings: 120 ÷ 2 per serving = 60
  • In the pack: 60 × 45 mg = 2.7 g
  • £25.99 ÷ 2.7 g × 268 mg = £2.58 per 268 mg
  • A week £2.58 × 7 = £18.06 · a month × 30 = £77.39 · a year × 365 = £941.61
