Creatine for Men Over 60: Muscle, DHT & Kidney Tests

For men over 60, creatine monohydrate is one of the few supplements with consistent randomized-trial support, but only when it is paired with resistance training. On its own it is not a muscle-building pill. This page covers the questions older men ask most: how much muscle and strength to expect, whether it affects testosterone, DHT or hair, why it can make a kidney blood test look worse than it is, and how to take it. For the wider over-60 picture (bone and brain as well as muscle, for men and women), see our creatine guide for adults over 60.

Evidence grade: B for creatine plus resistance training for lean mass and strength in older adults (several meta-analyses of RCTs). Grade D for creatine without training.

Key takeaways

• Across 22 RCTs (721 adults, mean age 57–70), creatine taken during resistance training added about 1.4 kg more lean mass than training alone and produced modestly greater chest-press and leg-press gains (Chilibeck 2017).
• A 2025 RCT measured DHT and hair directly and found no difference vs placebo after 12 weeks. The hair-loss worry comes from a single 2009 rugby study.
• Creatine raises serum creatinine, which can lower a calculated eGFR without any kidney damage. Tell your doctor before blood work.
• 3–5 g/day creatine monohydrate is enough. Loading is optional, and premium forms are not needed.

What to expect in muscle and strength

Two meta-analyses of older adults agree on direction and size. Devries and Phillips (2014; 357 adults averaging about 64, roughly 12 weeks of training) found creatine plus resistance training increased fat-free mass, chest-press and leg-press 1RM, and the 30-second chair-stand test more than training alone (PMID 24576864). Chilibeck et al. (2017; 22 trials, 721 participants) estimated +1.37 kg lean tissue (95% CI 0.97–1.76) with small-to-moderate strength advantages (PMID 29138605).

What this means in practice:

• The benefit sits on top of training two to three times a week. If you are not lifting, start there first.
• Part of the early lean-mass gain is water stored inside muscle. Real tissue gains build over months.
• Some knee-extension and isokinetic tests did not differ, so not every strength measure improves.

Testosterone, DHT and hair

The concern traces to van der Merwe et al. (2009). In 20 college rugby players, a 25 g/day loading phase raised DHT by 56% while testosterone did not change. Hair was never measured (PMID 19741313). In 2025, Lak et al. randomized 45 resistance-trained men to 5 g/day creatine or placebo for 12 weeks. They found no group differences in DHT, the DHT-to-testosterone ratio, hair density, follicle counts or hair thickness (PMID 40265319). Neither trial studied men over 60, so treat this as reassuring, not definitive. If you already use finasteride or dutasteride for prostate or hair reasons, there is no known interaction.

The kidney-test trap

Creatine breaks down to creatinine, the marker labs use to estimate kidney function (eGFR). Supplementing can raise serum creatinine and make eGFR look lower even when the kidneys are healthy. A published case report describes "pseudo renal failure" from a creatine supplement that resolved after stopping (PMID 25239988). For men over 60, who are more likely to have routine kidney panels or take kidney-relevant drugs:

• Tell your doctor you take creatine before blood work.
• If a result is borderline, ask about a cystatin C test, or repeat the test after 2–4 weeks off creatine.
• With known chronic kidney disease, do not start without your nephrologist's approval.

The ISSN position stand and its 2021 follow-up conclude that creatine at recommended doses has not been shown to harm kidney function in healthy people (PMIDs 28615996, 33557850).
