I've bought pure caffeine powder and its serving size is said to be a microscoop, but no measure of weight is given.

So what's/what size is a microscoop?


"Microscoops" can be found from the internet, but their size is 7-12mg. Is this reasonable for caffeine?

Yes, 7-12mg is a perfectly reasonable, very conservative amount. 12mg of caffeine is about equal to the amount of caffeine in a liquid ounce of 'average' coffee. (Source USDA)

Take care not to pack the scoop. Pure caffeine is a potentially dangerous ingredient. Microscoops vary even more than what is implied by your question, I've seen them as large as 50mg; a comment here tells of a 100mg microscoop. Again, take care, and know exactly what you have.

For greater accuracy, consider a milligram scale which can be had for about $20 US.

  • A liquid ounce is around 0.3dl so if 12mg of caffeine corresponds to the caffeine in 0.3dl of coffee, then it's not much. Somewhere (google.com/search?q=pure+caffeine+miscroscoop+100mg) the serving for pure caffeine was said to be "100mg microscoop". But I would want to avoid taking too much of caffeine, since it can be dangerous – mavavilj Sep 6 '16 at 7:19

    +1 for mentioning the danger of pure caffeine. One can't really poison oneself with brewed coffee, but with caffeine powder (1). – Stephie Sep 6 '16 at 7:38
  • I don't know about the "7-12mg is a perfectly reasonable, conservative amount" though. One cup (8 fl oz) is said to contain 94,8mg of caffeine. In that sense (since surely the pure caffeine I have is the same thing as that in the measurement) one could equate ~100mg of the pure caffeine powder into 1 cup of coffee. – mavavilj Sep 6 '16 at 12:16
  • @mavavilj That's why I called it conservative. I'll edit it to say very conservative. – Jolenealaska Sep 6 '16 at 12:20
  • Actually, looking closer the pure caffeine bags that I bought had the microscoop in them, but it was hidden into the caffeine itself. So this is their measure of "microscoop". The volume is about the size of a medium sized pill or a button cell. They say in the bag that the microscoop would be 180mg. Perhaps, it looks like it's something between 100-180mg (I know the size of a 100mg caffeine pill). – mavavilj Sep 6 '16 at 12:37
