Why Creatine Is Becoming One of the Most Important Supplements for Women Over 40

The Growing Interest in Creatine for Women's Health

For years, creatine has been associated with bodybuilders, athletes and gym culture. Mention creatine and most people picture weight rooms, protein shakes and muscle gains.

Yet some of the most exciting research on creatine today has very little to do with sport.

In fact, researchers are increasingly exploring creatine's potential role in healthy ageing, particularly for women navigating the hormonal changes of perimenopause and menopause.

As women move through midlife, conversations around health often focus on hormones. While hormones undoubtedly play a significant role, there is growing recognition that supporting the body's ability to produce and use energy efficiently may be just as important.

This is where creatine enters the conversation.

What Is Creatine?

Creatine is a naturally occurring compound made from three amino acids. Around 95% of the body's creatine is stored in skeletal muscle, with smaller amounts found in the brain and other tissues.

Its primary role is to help recycle ATP (adenosine triphosphate), often referred to as the body's energy currency. Every movement, thought and cellular process requires ATP. When energy demands increase, creatine helps replenish these energy stores more efficiently, allowing cells to continue functioning optimally.

Although our bodies produce creatine naturally, we also obtain it through foods such as red meat and fish. However, dietary intake is often relatively low, particularly for those who consume less animal protein.

Why Is Creatine Suddenly Being Talked About?

Creatine is far from new and is in fact one of the most extensively researched supplements available, with decades of studies supporting its safety and effectiveness.

What has changed is the focus of the research.

Historically, most creatine studies looked at athletic performance and were conducted predominantly in men. More recently, scientists have begun exploring how creatine may support women through different stages of life, particularly during perimenopause and menopause.

As hormone levels change, women often experience shifts in energy, recovery, body composition, strength and overall resilience. Researchers are now investigating whether creatine may help support some of these areas by improving the body's ability to generate and recycle cellular energy.

While the science is still evolving, the results so far have sparked significant interest among health professionals and researchers alike.

Are Women Different When It Comes to Creatine?

Emerging research suggests they may be.

Women generally have lower creatine stores than men and often consume less creatine through diet. Some researchers also believe hormonal fluctuations may influence how creatine is utilised within the body.

For many years, women were underrepresented in sports nutrition research, meaning much of what we thought we knew about supplementation was based largely on male participants. That is now beginning to change.

As more female-focused research emerges, scientists are gaining a better understanding of how supplements like creatine may support women's health throughout midlife and beyond.

Beyond the Gym

One reason creatine is generating so much interest is that it challenges the traditional idea of what a sports supplement looks like.

While creatine remains popular among athletes, researchers are now exploring its potential relevance in areas such as healthy ageing, physical resilience, recovery, cognitive function and overall wellbeing.

Importantly, this does not mean creatine is a miracle supplement. It cannot replace a balanced diet, regular movement, quality sleep or effective stress management.

What makes it unique is that it supports one of the body's most fundamental processes: cellular energy production, and because every cell relies on energy to function, researchers are continuing to explore where creatine may have a role to play.

A New Conversation Around Healthy Ageing

For many women, the goal is not to look younger or train harder, it is to feel strong, capable and supported as their bodies change.

That is why creatine is becoming such an important topic of conversation. Rather than focusing solely on performance, the discussion is shifting towards maintaining vitality, resilience and quality of life throughout midlife and beyond.

The science is still developing, and there is much more to learn. However, the growing body of research suggests that creatine deserves far more attention than it has traditionally received.

In the coming years, it may become one of the most important supplements in the healthy ageing conversation for women.

At Vigor, we believe women deserve honest, evidence-based information about their health. As research continues to evolve, creatine is certainly a supplement worth watching 👀
