Ingredients & Purity — Micronized vs. Creapure®

What’s actually in the tubs?

Both products are single-ingredient creatine monohydrate powders — no carb fillers, stimulants, or blends. You get straight creatine to add to water or a shake, 5 g per serving standard.

Optimum Nutrition — Micronized Creatine

Optimum’s powder is “micronized,” meaning the creatine particles are mechanically reduced in size. Smaller particles:

mix more easily in liquid
feel less gritty
can dissolve faster for a smoother drink

Micronization improves solubility and user experience but does not change the creatine molecule or its core effectiveness.

Nutricost — Creapure® Creatine

Nutricost uses Creapure®, a branded German creatine made under tight controls (AlzChem). Creapure® is known for very high purity and low contaminants (minimal creatinine, di‑/tri‑creatine impurities), so batches are consistent and predictable.

Label facts & third‑party checks

Look for these on the label when you buy:

Single-ingredient creatine monohydrate (no fillers)
“Micronized” or particle-size info (for mixability)
Creapure® trademark (for source transparency)
Third‑party testing or seals: NSF, Informed‑Choice, or independent lab testing

How purity affects safety and long-term use

Higher purity lowers your exposure to contaminants and degradation products (like creatinine). That reduces stomach upset risk and makes long-term daily use safer and more predictable. In short: micronized = easier mixing; Creapure® = tightened manufacturing and purity — both are solid choices depending on whether you prioritize mixability or certified-source purity.

Effectiveness & Performance — What to Expect in the Gym

Research-backed gains (short and direct)

Creatine monohydrate reliably increases your muscle phosphocreatine stores, letting you produce more ATP for short, intense efforts. Expect measurable improvements in:

maximal strength, repeated sprint/power output, and work capacity between sets
faster recovery between high‑intensity bouts
lean mass increases (partly from water, then muscle over weeks)

Meta-analyses typically show strength/power benefits in the ballpark of 5–15% versus placebo across 4–12 weeks when you use 3–5 g/day (or a standard loading protocol).

Optimum Nutrition (micronized) — what you’ll feel

Because Optimum’s creatine is micronized, it dissolves faster and feels smoother. That can make dosing easier and may reduce the chance of undissolved particles irritating your stomach. The molecule is still creatine monohydrate, so muscle‑building effects match any pure CM if dose/timing is equal.

Nutricost (Creapure®) — what you’ll feel

Nutricost uses Creapure®, made under strict controls for purity and consistency. You’re less likely to encounter batch variability or trace impurities that could theoretically affect tolerance — especially useful if you’re sensitive or planning long-term daily use.

Onset timing, water weight & GI

Onset: with a loading phase (20 g/day for 5–7 days) you’ll saturate stores faster; at 3–5 g/day expect 3–4 weeks to peak effect.
Weight: expect 1–3 lb (0.5–1.5 kg) of initial water weight for many users; later gains are muscle.
GI/bloating: common only at high single doses or with poor mixing. Micronized powder often feels gentler; Creapure®’s purity can reduce rare GI complaints.
3

Usage, Mixability & Digestive Tolerance

How to take it (loading vs maintenance)

You can use either product the same way: a common loading protocol is 20 g/day (split into four 5 g doses) for 5–7 days, then 3–5 g/day maintenance. Or skip loading and take 3–5 g/day — you’ll reach full muscle saturation in ~3–4 weeks.

Scoop sizes & servings

Optimum Nutrition: 5 g per serving, 600 g jar = 120 servings. Some packages may not include a scoop, so you might need to measure.
Nutricost (Creapure®): 5 g per serving, 1,000 g = 200 servings. Scoop is typically included.

At 5 g/day, Optimum lasts ~120 days; Nutricost lasts ~200 days — useful when planning supply and budget.

Mixability & flavor

Both are unflavored. Optimum’s micronized creatine generally dissolves faster and feels smoother in water, so you’ll see fewer gritty particles. Nutricost Creapure® is very pure but can still settle or cling due to static — give it a quick shake or stir.

Reducing stomach upset

Split large doses (e.g., four 5 g servings for a loading day) rather than taking 15–20 g at once.
Take creatine with a carb-containing drink or your post-workout shake to aid uptake.
Drink extra water throughout the day to reduce cramping/bloating risk.
If you feel GI discomfort, lower the dose to 2–3 g twice daily and build up.

Storage & practical tips

Store both in a cool, dry place and keep the lid tightly closed to avoid moisture clumping.
Check the expiration/manufacture date on the label — most creatine powders are stable for years but verify the date.
If you travel or want convenience, Nutricost’s larger jar reduces refill frequency; Optimum’s smaller jar is easier to stash in a gym bag.

Price, Value & Packaging — Which Gives More Gain per Dollar?

Unit price and cost-per-serving

You’ll pay roughly $28 for Optimum’s 600 g (120 servings) and about $58 for Nutricost’s 1 kg (200 servings). That works out to:

Optimum: ≈ $0.047 per gram → ≈ $0.23 per 5 g serving.
Nutricost (Creapure®): ≈ $0.058 per gram → ≈ $0.29 per 5 g serving.

So on strict cost-per-serving, Optimum is the cheaper option.

Real-world value based on how much you use

If you train occasionally or want a smaller jar to rotate supplements more often, Optimum gives better value per dollar and is easier to finish before expiration. If you train daily and prefer fewer reorders, Nutricost’s 1 kg reduces how often you buy, even though it costs slightly more per serving.

Packaging, scoops & label clarity

Both come in resealable jars, but details differ:

Optimum: smaller 600 g jar (packaging may vary); sometimes no scoop included; clear brand labeling and serving size.
Nutricost: 1 kg jar; scoop typically included; label clearly states “Creapure®” and 3rd-party testing claims.

Shipping & availability on Amazon

Price you see can change. Third-party sellers, lightning deals, or Prime shipping can shift the final cost — sometimes Nutricost appears cheaper during sales. Always check current Amazon sellers, shipping fees, and whether the listing is fulfilled by Amazon to avoid inflated one-off prices.

Decide by your priorities: pick Optimum for the lowest routine cost-per-serving and smaller jar convenience, or pick Nutricost if you want a big Creapure® supply and fewer refills despite a slightly higher per-serving price.


Final Verdict — Which Creatine Should You Pick?

If you want branded purity and the best price-per-gram, Nutricost Creapure® is the clear winner for value and certified Creapure quality. Choose Optimum Nutrition if you prefer micronized mixability, a trusted brand, and a convenient 120-serving size for daily routines.

Both are effective for strength and recovery; pick Nutricost when purity and budget are your priorities, or Optimum when mixability and brand trust drive your decision. If you train multiple times weekly and want the cheapest per serving for long-term use, Nutricost gives the overall lowest long-term cost while Optimum saves mixing time and pocket space too. Ready to boost your gains? Decide whether Creapure purity or micronized convenience matters more to you.

  1. Been cycling creatine on/off for years. Curious whether anyone actually cycles or just stays on daily. For reference: I’m lazy, so daily is ideal for me 😂

  2. Quick question — is there a real performance difference between Creapure and generic micronized creatine? Or is it mostly marketing and purity labels?

    Asking because I’m cheap but also want results.

    1. I’ve used both — no magical gains with Creapure, but I did feel less bloated. If budget’s tight, ON is fine.

    2. Short answer: mostly purity and trace impurities. Creapure is a branded pharmaceutical-grade creatine with strict production standards. For most users, effect on strength/hypertrophy is the same, but some report fewer stomach issues with Creapure.

  3. Anyone else use creatine in the morning with coffee? I mix ON creatine into my coffee every day — dissolves fine and gives me that extra oomph for morning lifts.

    Works for me, but might be an acquired taste for some ☕️

  4. Not trying to be that person, but I experienced a bit of water retention with ON that I didn’t get with Nutricost.
    I know creatine draws water into muscles, but the ON batch I had felt puffy for a week. Maybe dosage was off? 🤷‍♀️

    1. Water retention is common when starting creatine. It often subsides after a few weeks. Differences between brands can influence GI water handling for some users though.

    2. Might be sodium or filler in some formulations? Check the ingredient list, but generally pure creatine monohydrate is just creatine.

    3. I find drinking more water helps even out that puffy feeling. Also ramping up slowly vs loading helps me.
