Optimum Nutrition Micronized Creatine review

Optimum Nutrition Micronized Creatine gives you the same 5g of creatine monohydrate as the local tubs, plus one thing most of them don’t publish: an exact protocol for how to take it.

A published protocol, not just a scoop size

A serving is 5g, which Optimum Nutrition specifies as one rounded teaspoon of micronized creatine monohydrate. The brand then does something most listings here skip. It publishes the whole schedule: an optional loading phase of 20g to 25g a day for the first 4 to 5 days to fill your muscle stores faster, then 5g to 7g a day to hold them there. Loading is genuinely optional. Take 5g daily from day one and you reach the same saturation point, roughly two to three weeks later instead of one.

That guidance is worth more than it looks if creatine is new to you, because the most common way people get it wrong is treating it like a pre-workout and taking it only on gym days.

What a loading week costs you in powder

Here’s the part the protocol doesn’t spell out. Loading at 20g to 25g a day for 4 to 5 days uses 80g to 125g of powder before you start a single maintenance day. In standard 5g servings, that’s 16 to 25 of them gone in under a week, a real bite out of any tub. If your budget is tight, skipping the loading phase is the cheaper road to the same place, and the brand’s own instructions say so.

Are you paying for the creatine or for the name?

At around ₱1,600 as of August 24, 2026, this costs several times what a local tub with the same published 5g dose costs. Be clear about what the extra buys, because it isn’t a better compound: creatine monohydrate is creatine monohydrate. What you get is a global brand with a long audit history, a dosing protocol in writing, and a 4.9 Shopee rating across 10,365 ratings. Micronization keeps it mixing cleanly, though several cheaper tubs here are micronized too.

Who the Optimum Nutrition premium makes sense for

Buy this if brand track record is what makes you comfortable taking a supplement daily, and you’d rather follow written instructions than guess. It’s a fair first tub if that reassurance is the thing that gets you started. If you already understand how creatine works and just want the compound, you’re paying a large premium for packaging and paperwork.

Cheaper routes to the same 5g

For the identical dose at a fraction of the price, see Pure Form Ultra-Micronized Creatine. For the largest owner base in the category, see ACTIVE Creatine Monohydrate. If you want an international brand in a bigger tub, MuscleTech Platinum Creatine ships 80 servings.
