Creatine in Cancer Survivorship: Why Quality Matters More Than Ever
When most people think of creatine, they think of bodybuilders and gym culture. But the reality is very different.
Creatine is one of the most extensively researched supplements in the world, with strong evidence supporting its role in muscle strength, physical function, recovery, and brain energy metabolism. These benefits make it especially relevant for cancer survivors, where preserving strength, resilience, and independence becomes increasingly important.
However, there’s a critical issue that rarely gets discussed:
Not all creatine supplements are created equal and some don’t contain meaningful amounts of creatine at all.
In this blog I explain why creatine can be such a valuable tool in survivorship, what the research actually shows, and how to choose a product that is both safe and effective.
Why Creatine Matters in Survivorship
From our 40s onwards, we naturally begin to lose muscle mass and strength, a process known as sarcopenia. Bone density also declines, balance and recovery become slower, and the risk of falls and frailty increases.
For people who have undergone cancer treatment, these changes are often accelerated by:
Treatment-related fatigue and deconditioning
Loss of lean body mass
Hormonal changes (including early or treatment-induced menopause)
Reduced physical activity during and after treatment
Over time, this can contribute to:
Ongoing fatigue
Reduced independence and confidence
Increased risk of falls and fractures
Worsening insulin resistance and metabolic health
Cognitive fatigue and “brain fog”
Preserving muscle mass and strength is not about aesthetics. It is one of the strongest predictors of healthy ageing, functional independence, and long-term health outcomes in both the general population and cancer survivors.
What the Research Says About Creatine
Creatine monohydrate is one of the most studied nutritional supplements in existence.
Decades of research show that a daily dose of 3–5 grams of creatine monohydrate can:
Improve muscle strength and power
Support gains in lean muscle mass when combined with resistance training
Improve physical function and performance
Support cellular energy production
There is also growing interest in creatine’s role in:
Brain energy metabolism
Cognitive function
Mental fatigue and neurological resilience
All of which are highly relevant in post-cancer recovery.
The Problem: Not All Creatine Products Actually Contain Creatine
Here’s where things get concerning.
Independent laboratory testing by SuppCo of popular creatine gummy products found that 40–50% contained little to no measurable creatine and some contained zero grams per serving, despite what their labels claimed.
In other words, people were buying and consuming products that simply did not contain the active ingredient.
Why Gummies and Drinks Are Especially Problematic
Creatine is not a stable compound in moist, heat-processed formats.
Gummies and Drinks:
Are difficult to manufacture with accurate dosing
Are exposed to heat and moisture, which can degrade creatine
Often contain very small theoretical doses to begin with
Prioritise taste and marketing over therapeutic effectiveness
As a result, many of the gummies tested failed to match their label claims, meaning people were effectively consuming sugar with no clinical benefit.
For people in cancer recovery or midlife health optimisation, this is more than just a waste of money — it is a missed opportunity to support strength, function, and recovery.
How to Choose a High-Quality Creatine
If creatine is appropriate for you, here’s what actually matters:
1. Choose the Right Form
The gold standard is creatine monohydrate. It is:
The most researched
The most effective
The most affordable
The best tolerated
There is no good evidence that more expensive “designer” forms are superior.
2. Look for Third-Party Testing and Quality Assurance
Choose brands that:
Provide third-party testing
Have strong quality control processes
Are transparent about purity and sourcing
In clinical practice, this really matters, especially for people with complex health histories.
3. Consider Creapure®
If possible, look for products that use Creapure®, a patented, pharmaceutical-grade creatine monohydrate produced in Germany. It is known for:
Exceptional purity
Low contamination risk
Use in research and clinical trials worldwide
Practitioner-Grade Options
Some reputable options include:
ATP Science Creatine
True Protein Creatine Monohydrate
Designs for Health Creatine Monohydrate
RN Labs Creatine Monohydrate
(These are examples only and not sponsored recommendations.)
Dosing and Safety Considerations
The typical evidence-based dose is 3–5 grams per day.
Creatine is generally very well tolerated in healthy individuals, but in clinical contexts (including cancer survivorship, kidney concerns, or complex medication profiles), supplementation should always be individualised and supervised.
This is particularly important if you:
Have kidney disease
Are on multiple medications
Are undergoing or recovering from cancer treatment
Have complex metabolic or cardiovascular conditions
The Bigger Picture: Muscle Is Medicine
For cancer survivors, muscle is not about appearance.
It is about:
Independence
Fall prevention
Metabolic health
Treatment resilience
Healthy ageing
Long-term quality of life
Creatine can be a powerful, evidence-based tool to support this, but only if it is:
The right form
The right dose
From a trustworthy, properly tested source
If a supplement isn’t verified, properly formulated, and evidence-based, it isn’t supporting your health — it’s just selling hope.
And in midlife health and survivorship, hope is not a strategy. Evidence and quality are.
A Final Word
If you’re unsure whether creatine is appropriate for you or whether your current supplement is actually doing what it claims, this is exactly the kind of thing I review with clients in clinic.
Personalised, evidence-based supplementation matters, especially when your health history is complex.
