I have ten equal sized tupperwares that can hold all my powders, I have a blender and a digital scale.
I weigh out and measure all the powders (protein / carbs / sulfur / salts) and put them in the tubs, I have a little dispoable plastic cup for the malto and oat powder, all the salts can fit on my digital food scale.
At this point I only have to add my lipids (fats and oils) and whatever vitamins (including the fish oil capsule) , my vitamin k is a tablet , the chromium, selenium and copper are all little capsules, I open them and poor them in the day of.
So I get my premixed powder out, make a little divot with the bottom of a pill bottle and add the oil and magneisum chloride (mine is liquid right now) , I add the contents of the selenium / copper and chromium pills. Now all I have seperate is my vitamin k tablet and fish oil capsule.
I add water to a blender and blenderize it all, then I poor 2/3 of the mix back into the tupperware, I add more water to the remaining 1/3 in the blender, blenderize it further and poor that in a big cup, thats breakfast. I drink that and have my vitamin K and fish oil capsule for breakfast.
The other two meals are now stored in my fridge in the tupperware, i pour half out for lunch, add more water and blenderize, repeat for dinner.
If I’m taking it on the go I just blenderize to a palatable consistency and put it in a bottle.
If I don’t mix the powders beforehand this entire process still takes less than 5 minutes from start to finish, you kind of get good after 10 or so tries at pouring out proper amounts.
