Creatine monohydrate has over 30 years of peer-reviewed research behind it and is the single most proven performance supplement in existence. Five grams a day, mixed into literally anything — water, coffee, your protein shake — increases your ability to produce force during short, intense efforts. That translates directly to heavier lifts, more reps, and faster recovery between sets.
The supplement industry runs on selling complexity: $80 pre-workouts with 20-ingredient stacks, proprietary blends with trademarked names, "advanced" creatine forms at 6× the price. All of it outperforms plain monohydrate in one category: marketing. In actual research, plain creatine monohydrate is as effective as every "enhanced" form, for a quarter a day.
Optimum Nutrition's unflavored monohydrate is the benchmark. No flavoring, no filler, 100 servings per 500g tub. It's the supplement that actually earns the counter space.
Optimum Nutrition was founded in 1986 in Aurora, Illinois and built its reputation on the Gold Standard Whey line — which became the benchmark protein powder for decades. Their unflavored creatine monohydrate followed the same philosophy: no shortcuts, no proprietary spin, just the proven ingredient at a fair price.
ON operates out of several manufacturing facilities with third-party testing through Informed Choice. They're owned by Glanbia PLC but have maintained product quality through the transition. The brand is the default recommendation in sports nutrition for a reason — they've never tried to reinvent a product that was already perfect.
Mix one flat teaspoon (5g) into any liquid. It dissolves better in warm liquid but works fine cold. The timing doesn't matter — morning, pre-workout, post-workout, or before bed all produce the same result. What matters is taking it every day without skipping.
Expect a 2–3 lb weight gain in the first two weeks — that's water being pulled into muscle cells, which is the mechanism. Strength gains start becoming noticeable around weeks 3–4. If you stop taking it, those gains revert over 4–6 weeks.
