A fancy term for ‘powdered’. So when all those supplement labels you read sound high tech, that’s what it means. Example: the creatine I buy comes in granular or ‘micronized’.

Same stuff.

Important to note is that powders will absorb a little faster, dissolve in drinks faster, etc. Or aren’t gritty like creatine which doesn’t dissolve very well.

Like this creatine in my Amazon store.
