If you haven’t come across a proprietary blend then let me explain. On some nutrition supplements you will notice that rather than listing all of the ingredients in the product along with the amounts for each, some only list the total amount of ingredients in grams, and then list the individual ingredients in a list below.
This is what’s known as a proprietary blend e.g. the ingredients list might read Brand X proprietary blend 8g, and underneath lists Creatine monohydrate, L-Arginine, Beta- alanine, Citrulline Malate, but does not state how much of each ingredient is in there!
A simple way of roughly working out how much of an each ingredient is in the product (and therefore testing the products quality) is to do the following:
Take the total quantity of the proprietary blend, in this case it is 8g or 8,000mg. We know there are 4 ingredients in the product so simply divide 8,000mg by 4 = 2,000mg. However it is worth noting that the order an ingredient is listed in the blend is representative of the quantity in the product, consequently the chances of there being 2,000mg of each ingredient is highly unlikely.
It is more likely that the first ingredient on the list i.e. Creatine monohydrate is actually considerably higher than the rest, in fact it could be that the blend is comprised of 7,900mg of creatine and the rest is just made up of trace amounts. Again, this is highly unlikely, so to get a rough idea divide 8,000 by 4 = 2,000. Then estimate the possible high end totals for each ingredient by dividing the total quantity in the blend by its position in the proprietary blends list:
The lowest possible for each ingredient would be 2000mg for creatine and trace amounts for the rest. The highest possible quantities would be as follows (using the above calculation):
Creatine Monohydrate >>> 8,000mg divided by 1 = 8,000
L-Arginine >>> 8,000mg divided by 2 = 4,000
Beta- alanine >>> 8,000mg divided by 3 = 2,667
Citruline Mallate >>> 8,000mg divided by 4 = 2000
We must now find the average by taking the highest and lowest possible quantities, adding them together and dividing that by how many there are.
This would mean the Brand X proprietary blend 8g would deliver approximately:
4,950mg Creatine Monohydrate
2,500mg L- Arginine
1,666mg Beta- alanine
1,250mg Citruline Mallate
Compare these figures to the ideal clinical dose of each ingredient and you can see if you’re getting enough of each.
