From your data, there is no reason to use magnesium chloride hexahydrate.

@AWK

Im not sure what you mean. Are you suggesting it could be completely omitted from the formulation or do you mean that Magnesium Chloride anhydrous would be better suited?

In your first post, you indicated only: magnesium chloride.
Both salts are on the market.

Yes, so I picked one.

For the anhydrous the calculation is 95.211* 20 = 1904.22 / 24.305 = 78mgs vs 167mgs for the hexahydrate.
The difference is minor and the total weight changes to only 4.51g vs 4.6g with the hex.

Now you must accept that the supplement to the weight of up to 5 g contains some additives that are the company's secret.

Or that the weights and values are based on a typically sized scoop which was 4.5-4.6g rounded up to 5g. One or the other.

This could be true but I would bet lots of my own money it is not.

Or that the weights and values are based on a typically sized scoop which was 4.5-4.6g rounded up to 5g. One or the other.

This could also be true but I would bet lots of my own money it is not.

This company is selling a mixture of 4 things:

sodium bicarbonate
potassium bicarbonate
calcium carbonate
magnesium carbonate

all 4 reagents will be bought to a specification which will not be 100% more likely is >99%.
They will be weighed out individually and mixed which will have an accuracy of again something like >99% for each weighing.

When you put all that together the most likely assumption is that the 4 raw materials are mixed together and the errors are potentially ~8% combined and 92% of 5g is 4.6g.

Thanks DrCMC. Sounds like the most plausible and scientific explanation.
