Creatine and Menopause: What Science Really Says

Creatine monohydrate was long considered a supplement for male athletes. Today the science tells a different story: women going through menopause stand to benefit in a particularly meaningful way — for muscle strength, bone health, and mental clarity. Here is what the research actually shows, and what matters when it comes to supplementation.

What is creatine — and why does menopause change everything?

Creatine is a naturally occurring compound synthesised in the body from the amino acids arginine, glycine, and methionine, and taken in through food — mainly red meat and fish. In the muscle, it is stored as phosphocreatine and serves as a rapidly available energy source during short, intense efforts.

What many people do not know: women naturally carry lower creatine stores than men — approximately 70–80% of male levels.^[1] During menopause, these stores decline even further, because falling oestrogen levels impair muscle protein synthesis and slow cellular energy metabolism. The consequences are noticeable: accelerated muscle loss, persistent fatigue, and reduced mental sharpness.

What happens in the body during menopause?

The hormonal shifts of menopause affect several body systems simultaneously:

• Oestrogen drop → accelerated muscle loss (sarcopenia)
• Declining bone density → increased fracture risk
• Reduced mitochondrial function → chronic fatigue
• Lower brain creatine levels → brain fog and mood changes

Creatine supplementation targets each of these pathways — and the science provides compelling arguments for its use.

Creatine and muscle strength: what studies show

The strongest evidence for creatine in menopause centres on muscle mass and strength. Multiple controlled trials show that creatine monohydrate combined with resistance training significantly increases lean muscle mass and strength in postmenopausal women — beyond what exercise alone can achieve.^[2]

A systematic review and meta-analysis published in 2025 confirmed that older adults — and postmenopausal women in particular — gain significantly more lean mass when combining creatine supplementation with resistance training compared to training without supplementation.^[3]

From age 40, women lose approximately 0.5–1% of their muscle mass each year. In peri- and postmenopause, this process accelerates sharply. Less muscle means not only less strength — it also raises the risk of falls, metabolic disorders, and cardiovascular disease.

Creatine and bone health: cautiously optimistic

The most comprehensive long-term study on this topic comes from Chilibeck et al. (2023). In this 2-year randomised controlled trial involving 237 postmenopausal women, participants received either creatine monohydrate or a placebo alongside a structured resistance training programme.^[4]

Creatine did not significantly improve bone mineral density directly. However, the creatine group showed:

• Fewer vertebral deformations
• Better muscle function — which indirectly reduces fracture risk
• Greater lean mass gains

Creatine supports bone health primarily indirectly — through greater muscle mass, improved balance, and reduced fall risk. Combined with high-quality collagen and adequate vitamin D, it forms part of a strong, holistic bone-health strategy.

Creatine and the brain: easing brain fog

Brain fog — poor concentration, forgetfulness, and mental fatigue — is one of the most disruptive and frequently underacknowledged menopause symptoms. Science increasingly confirms that creatine not only fuels muscles but also supports brain energy metabolism.^[5]

Smith-Ryan et al. (2021) demonstrated in a landmark review that creatine supplementation in peri- and postmenopausal women raises brain creatine concentrations, with potential benefits for working memory, processing speed, and general cognitive performance.^[1]

Early evidence also suggests that low brain creatine levels may be associated with depressive symptoms — particularly in women experiencing hormonal transitions. The research is still developing, but the early findings are encouraging.^[5]

How to take creatine during menopause

The dosage of creatine monohydrate is well established and straightforward:

• Recommended daily dose: 3–5 g creatine monohydrate per day
• Loading phase (optional): 20 g/day for 5–7 days, then 3–5 g/day
• A loading phase is not required — it simply saturates creatine stores faster
• Creatine can be taken at any time of day; consistency matters most
• Dissolve in water, juice, or a shake — creatine monohydrate is odourless and tasteless

Is creatine safe for menopausal women?

Creatine monohydrate has an excellent safety profile in healthy individuals, including postmenopausal women. Long-term studies spanning up to two years show no adverse effects on kidney or liver function at recommended doses.^[4]

Possible, harmless effects include mild intramuscular water retention and, occasionally, minor gastrointestinal discomfort if large doses are taken on an empty stomach. Women with pre-existing kidney conditions or those on prescription medication should consult their doctor before supplementing.

Creatine and collagen: better together

Creatine and collagen work on different levels — and complement each other beautifully for women in menopause:

• Creatine delivers energy for muscles and the brain, and supports muscle synthesis
• Collagen provides essential building blocks for skin, joints, connective tissue, hair, and nails

During a life phase when the body is simultaneously managing a drop in multiple hormones, a holistic supplementation approach makes sense. Our Glow25 Collagen Powder delivers high-quality collagen peptides for skin, joints, and connective tissue — the ideal companion to your daily creatine routine.

For maximum effect, we recommend our Glow25 Collagen Intensive with its advanced tripeptide formula, designed for maximum bioavailability.

Tips for optimal intake during menopause

• Pair creatine with resistance training: the evidence for muscle mass benefits is clear — exercise makes the difference
• Eat enough protein: the body needs amino acids to build and maintain muscle
• Take it daily: creatine works cumulatively — regularity matters more than precise timing
• Combine with collagen: for a comprehensive wellness programme for body and mind
• Be patient: measurable effects typically appear after 4–8 weeks of consistent intake

Creatine in menopause — a conclusion

Creatine monohydrate is one of the very few supplements with solid, replicated scientific evidence of benefit in postmenopausal women. Greater muscle strength, indirect support for bone health, and genuine promise against brain fog — with an outstanding safety profile and a simple, flexible dosing routine.

Combined with high-quality collagen from Glow25, creatine forms a powerful foundation for health, energy, and wellbeing during this life stage — and beyond.
