Sorry I should've said its also got a dash of magnesium as well.Theoretically there is Magnesium in AFR but not much. Here is the official DYI AFR recipe from TM and you can see there is almost none per 1litre.
Unless TM substantially changed the formulation you will not get significant boost in Mg from AFR.
But it is there.
But thank you for the recipe.. when I start back dosing AFR myself I'm going to have to check and see how much it changes my magnesium just out of curiosity.
