Creatine microdosing (1–2 g/dag): werkt het? (2025) | ZOOO Nutrition

TL;DR (≤60 words)
1–2 g/day can be maintenance after prior saturation, but for demonstrable performance claims and a rapid increase in muscle creatine, 3–5 g/day is the standard. EFSA explicitly links the performance claim to ≥3 g/day; studies show 2 g/day as maintenance after loading, not optimal build-up. efsa.onlinelibrary.wiley.com+1

Intro (Why it matters)
"Microdosing"—a small amount of creatine every day—sounds appealing: less powder, fewer gummies, perhaps fewer side effects. But what does the evidence say about 1–2 g/day? In this guide, you'll get a clear conclusion: when microdosing makes sense (maintenance), and when it's better to stick to 3–5 g/day (build-up, performance, EU claim). We support this with ISSN, EFSA, and classic tissue studies. BioMed Central+1

What exactly is microdosing (1–2 g/day)?

Microdosing = low, fixed daily dose (1–2 g) without a loading phase. The idea: "slowly fill up" with mini-doses and maintain more easily. In practice, dose × time determines how quickly muscle creatine increases. ISSN therefore classically advises 3–5 g/day (or loading) for reliable, noticeable effects. BioMed Central

What does science say? (brief and honest)

  • Maintenance after loading: In Hultman 1996, an increased muscle creatine concentration after loading was successfully maintained with 2 g/day (30 days). This indicates a maintenance value of 2 g/day—but not rapid build-up from zero. PubMed+1

  • Build-up without loading: Classic work (Harris 1992) showed that higher daily doses (≈20 g divided; then 3–5 g/day) significantly increase muscle creatine; low doses often do not reach that threshold quickly. PubMed+1

  • Sports performance at 2 g/day: Reviews in swimmers and endurance components show no or limited effects at 2 g/day over 6 weeks—likely too low for clear performance gain. jssm.org+1

  • Consensus frameworks: ISSN maintains 3–5 g/day as the best-supported maintenance dosage; EFSA explicitly links the EU performance claim to at least 3 g/day. BioMed Central

Bottom line: 1–2 g/day can support maintenance (after saturation). If you want to saturate quickly and/or communicate legally claimable performance effects within the EU, assume ≥3 g/day. efsa.onlinelibrary.wiley.com

EFSA & claims: what can you say?

The EU performance claim ("increased performance during short, repeated bursts of high-intensity exercise") applies to ≥3 g/day of creatine. At 1–2 g/day, you do not meet this claim threshold and therefore cannot make the performance claim. For 55+, there is an additional claim in combination with resistance training. efsa.onlinelibrary.wiley.com+1

Practical: when can microdosing be used?

  1. Maintenance after saturation
    – If you have first loaded (~20 g/day, 5–7 days) or taken 3–5 g/day for weeks, then 2 g/day can maintain your higher muscle creatine level. PubMed

  2. Ultra-long horizon, no rush
    – If speed is unimportant to you, then 2 g/day over a very long term could provide some build-up, but evidence is limited and slow. 3–5 g/day remains more predictable. BioMed Central

  3. Budget or GI comfort
    – Some athletes temporarily opt for lower doses to gauge tolerance. Then increase to 3–5 g/day as soon as possible; this also aligns with EFSA. BioMed Central

When is microdosing not recommended?

  • Starting phase without loading → choose 3–5 g/day for a significant increase in 3–4 weeks. BioMed Central

  • Performance claim/EU-compliance≥3 g/day required. efsa.onlinelibrary.wiley.com

  • Short preparation (competition within 2–3 weeks) → microdosing is too slow; choose loading or 3–5 g/day. PubMed

Gummies vs powder for microdosing

The molecule is the same; the difference is in dosing, convenience and €/5 g. For gummies, pay attention to mg per gummy and ask for a CoA. The recent Wired case shows that some gummies were underdosed—transparency is crucial. WIRED

Schedules (practical)

A) Start without loading phase (recommended for simplicity)

  • 3–5 g/day (gummies: 3–5 × 1,000 mg) → steady saturation in ~3–4 weeks. Anchor: breakfast. BioMed Central

B) Classic loading (rapid increase)

  • 5–7 days: ~20 g/day divided (4×5 g), then 3–5 g/day maintenance. Microdosing 2 g/day can be maintenance at a later stage, but not for buildup. PubMed+1

C) Hybrid (comfort-first)

  • Week 1: 3 g/day; week 2–4: 4–5 g/day; then evaluate. If GI sensitive, spread throughout the day.

Do’s & Don’ts (checklist)

Do

  • Aim for 3–5 g/day (or loading) for predictable results. BioMed Central

  • View 1–2 g/day as maintenance, not primary buildup. PubMed

  • Check mg per gummy + CoA (especially after gummy-gate). WIRED

  • Take every day, even on rest days (consistency > timing). BioMed Central

Don’t
