The photos below show 3.00g and an approximately 5g example (5.20g in the original scale photo), using the creatine powder, measuring spoons and scale I tested. Spoon volume can vary with the powder and how level or heaped it is, so use the photos as a visual reference — not a universal teaspoon conversion.
How I measured these photos
Measured using the 5 mL spoon shown and a DIAMOND scale with a 0.001g display resolution (a display resolution, not a calibrated ±0.001g accuracy claim). The powder is micronized creatine. The 3.00g and 5.20g examples were weighed independently — not converted from one spoon.
MOST ACCURATE
Digital scale: Weighs the actual mass in grams. The reliable way to hit 5g.
USEFUL
Manufacturer scoop: Works when the scoop and the labeled gram amount actually match.
ESTIMATE
Proper measuring spoon: A rough estimate — volume, not mass. Depends on how you level or heap it.
LEAST RELIABLE
Random household teaspoon: Varies most. Don't count on a fixed gram amount.
Not reliably. Grams are mass; a teaspoon measures volume. Powder density, particle size, and how much you heap or pack the spoon all change how many grams actually end up in it. That's why the photos are a visual reference and the scale is the answer.
Because grams and millilitres measure different things. A gram is mass; a millilitre is volume. To convert between them you need the powder's density, and creatine density varies with the form, brand, particle size and how compacted the powder is.
So a single "5g = X mL" number doesn't hold across products or even across scoops of the same tub. If you want an exact 5g, weigh it — a volume figure is only ever an approximation.
Is 3g enough?
A classic study found that about 3g/day over 28 days gradually raised muscle creatine stores, while a roughly 20g/day loading protocol over six days raised them much faster. So 3g/day can work; loading mainly changes how quickly stores rise.

Do you need exactly 5g every day?
No. Five grams is a simple, common maintenance amount — not a magic threshold. This page is about seeing what that amount looks like, so treat 5g as a convenient round number rather than an exact requirement.
What about a loading phase?
Loading is a way to reach saturation faster — it's not required for creatine to work. You can skip it and take a steady daily amount, which raises stores more gradually.
More isn't automatically better, and larger single servings are more likely to cause stomach trouble. A randomized trial found diarrhea was more common when 10g was taken as a single serving than when the same daily amount was split into smaller servings.
There's no requirement to cycle on and off simply to "reset tolerance." Creatine doesn't build the kind of tolerance that a break would reset.
Longer-term studies have used continuous supplementation without showing a need for periodic breaks. A 2026 systematic review and meta-analysis found no significant change in eGFR or urea, while serum creatinine increased slightly — an expected creatine-related change — and the need for more long-duration trials.
