Creatine — Why Kiwis Should Care
Share
TL;DR
Creatine monohydrate is one of the most researched supplements in history with over 500 human studies. It's not just for bodybuilders — emerging research shows significant benefits for brain health, mood, bone density, and women's health. Most New Zealanders would benefit from 3-5g daily. Dr. Stacy Sims, Dr. Andrew Huberman, and Dr. Rhonda Patrick all recommend it. A 2024 meta-analysis confirms significant strength gains with creatine + resistance training in adults under 50.
Evidence Rating for Creatine Monohydrate: ⭐⭐⭐⭐⭐ Robust
(One of the most studied supplements in the world — backed by hundreds of RCTs, multiple meta-analyses, and consistent expert consensus across physical performance, cognitive function, and women's health.)
What Is Creatine?
Creatine is a naturally occurring compound found in muscle and brain tissue. Your body makes about 1-2g daily, and you get additional creatine from meat and fish. Supplementing with creatine monohydrate increases your body's phosphocreatine stores, which are used for rapid energy production in both muscles and the brain.
Most New Zealanders — especially women, vegetarians, and older adults — have lower baseline creatine stores and stand to benefit significantly from supplementation.
The Research — What Actually Works
1. Cognitive Performance & Brain Health
A 2023 systematic review and meta-analysis found that creatine supplementation significantly improved short-term memory and reasoning in healthy individuals, with the strongest effects in stressed or sleep-deprived populations.

2. Physical Performance & Strength
Creatine is the most effective legal supplement for increasing high-intensity exercise capacity and lean body mass. A comprehensive meta-analysis confirmed significant improvements in strength and power output.

3. Women's Health (Perimenopause & Menopause)
Dr. Stacy Sims has been a leading voice on creatine for women. Research shows creatine may support bone mineral density in postmenopausal women and improve mood and cognitive resilience during hormonal transitions.

The New Zealand Creatine Opportunity
New Zealanders — particularly women, vegetarians/vegans, and older adults — typically have lower baseline creatine stores. This makes creatine one of the highest-ROI daily supplements for cognitive performance, strength, and healthy ageing in New Zealand.
Who Should Consider This
- Women — especially during perimenopause and menopause (Dr. Stacy Sims strongly advocates)
- Adults over 40 concerned about cognitive health and muscle maintenance
- High-performers, athletes, and anyone doing resistance training
- Vegetarians and vegans (typically have 20-30% lower baseline creatine)
- Shift workers, new parents, and anyone experiencing sleep deprivation
- Older adults wanting to support independence and bone health
Practical Dosage (From the Research)
Standard dose (performance & general use): 3-5g creatine monohydrate daily is sufficient for most people. A loading phase is not required for performance benefits.
For brain/cognitive benefits: Emerging research suggests higher doses (15-20g/day split into 3-4 doses for 5-7 days, followed by 5-10g maintenance) may help increase brain creatine levels after muscle saturation.
Timing: Any time of day — consistency matters more than timing. Take with a meal if possible.
Form: Creatine monohydrate is the most studied, effective, and cost-effective form.
Safety & Notes
Creatine is one of the most studied supplements with an excellent safety profile. The "kidney damage" concern has been thoroughly debunked in healthy individuals at standard doses.
Important: Stay well hydrated. Consult your doctor if you have pre-existing kidney conditions.
