What it really costs, per 500 mg£187.50One 500 mg dose is our comparison unit for niacin (vitamin B3). It is not a recommendation.
A day£187.50
A week£1312.50
A month£5625.00
A year£68437.50

At one 500 mg dose a day, this pack lasts under a day. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Niacin (vitamin B3)

  • Servings: 420 ÷ 21 per serving = 20
  • In the pack: 20 × 4 mg = 80 mg
  • £30.00 ÷ 80 mg × 500 mg = £187.50 per 500 mg
  • A week £187.50 × 7 = £1312.50 · a month × 30 = £5625.00 · a year × 365 = £68437.50
  • Amount per serving: stated on the label.

Beta-alanine

  • Servings: 420 ÷ 21 per serving = 20
  • In the pack: 20 × 3.2 g = 64 g
  • £30.00 ÷ 64 g × 3.2 g = £1.50 per 3.2 g
  • A week £1.50 × 7 = £10.50 · a month × 30 = £45.00 · a year × 365 = £547.50
  • Amount per serving: stated on the label.

Caffeine

  • Servings: 420 ÷ 21 per serving = 20
  • In the pack: 20 × 200 mg = 4 g
  • £30.00 ÷ 4 g × 200 mg = £1.50 per 200 mg
  • A week £1.50 × 7 = £10.50 · a month × 30 = £45.00 · a year × 365 = £547.50
  • Amount per serving: stated on the label.

L-Citrulline

  • Servings: 420 ÷ 21 per serving = 20
  • In the pack: 20 × 6 g = 120 g
  • £30.00 ÷ 120 g × 3 g = 75p per 3 g L-citrulline
  • A week 75p × 7 = £5.25 · a month × 30 = £22.50 · a year × 365 = £273.75
  • Amount per serving: stated on the label.

L-Leucine

  • Servings: 420 ÷ 21 per serving = 20
  • In the pack: 20 × 3 g = 60 g
  • £30.00 ÷ 60 g × 3 g = £1.50 per 3 g
  • A week £1.50 × 7 = £10.50 · a month × 30 = £45.00 · a year × 365 = £547.50
  • Amount per serving: stated on the label.

Pantothenic acid (B5)

  • Servings: 420 ÷ 21 per serving = 20
  • In the pack: 20 × 1 mg = 20 mg
