HOW TO USE THIS PAGE
Decide whether creatine deserves a real trial.
- 01Confirm the fit
Connect the intervention to a specific longevity & prevention outcome and review the evidence boundary.
- 02Set the protocol
Define amount, timing, quality standard and a realistic trial length before starting.
- 03Track one useful signal
Choose the measure that will tell you to continue, adjust or stop.
RECOMMENDED RANGES
Men and women may need different context.
We only show a different amount when physiology, dietary requirements or clinical evidence supports it. Otherwise, we say the range is the same.Typical guidance
Typical studied maintenance amount: 3–5 g/day. Women may benefit without needing a lower dose.
Important context: There is no established requirement to dose lower for women. Pregnancy and breastfeeding require clinician review.
WHAT IT MAY HELP WITH
Why people use it
Supports muscle and performance across aging. Its relevance here is specifically connected to longevity & prevention. Outcomes can differ when the same intervention is used for another purpose.
Strong evidence
Multiple consistent lines of human evidence support this use, although effect size and individual response still vary.
SERVING & PROTOCOL
How it is typically used
3–5 g daily
Creatine monohydrate is the best-studied form. A loading phase is optional, not required.
- Timing
- Any consistent time; with a meal is convenient
- How long to assess
- Ongoing use is common
QUALITY CHECK
What to look for
- A form, device, provider or protocol that matches the evidence—not just the marketing name.
- Transparent labeling, realistic claims and independent quality verification where applicable.
- A measurable reason to use it and a predefined way to judge whether it is helping.
- No hidden proprietary blend or pressure to replace proven medical care.
SAFETY & INTERACTIONS
What to know first
May increase scale weight through intracellular water. Discuss kidney disease or abnormal renal tests with a clinician.
Stop and reassessDiscontinue and seek appropriate care for a severe reaction, fainting, chest symptoms, breathing difficulty, neurological changes or rapidly worsening symptoms.
