How Much Creatine?
Still taking 5 g of creatine? You’re maintaining, not maximizing.
Optimal Dosing for Muscle Creatine and Performance
Maintenance Dose (5 g/day): Daily low doses around 5 grams of creatine monohydrate are sufficient to fully saturate or maintain muscle creatine stores over time.

Faster Saturation (8–10 g/day): Slightly higher daily doses (around 8–10 grams) can accelerate muscle creatine saturation and may produce greater performance gains in some cases. A recent meta-analysis noted that “high-dose” maintenance (>8 g/day) was associated with significantly larger strength increases (e.g. ~11 kg extra squat strength gained vs. ~4 kg with ≤8 g/day) and greater improvements in certain power/anaerobic measures

These findings suggest that individuals with larger muscle mass or low baseline creatine might benefit from higher daily doses, though even moderate doses eventually saturate muscles if given enough time.

Worried high-dose creatine isn’t safe? Science says otherwise.
High Doses and Long-Term Safety (≤30 g/day): Creatine has an excellent safety profile. Very high dosages (20–30 g per day) have been used in studies for extended periods without harm. In fact, the International Society of Sports Nutrition’s position stand reports that even up to 30 g/day for 5 years caused no adverse effects and was well-tolerated in healthy individuals
No evidence supports the myth of creatine causing organ damage when used at recommended or even high doses in people with no pre-existing kidney issues
→ That’s why FLXRX starts where others stop: 10 g of 100 % pure monohydrate for full saturation and the HIGHEST quality so you can digest higher doses effectively.

Why Use Creatine?
Clinically Backed Findings:
3–5 g/day → Maintains muscle creatine stores in healthy adults
8–10 g/day → Builds faster saturation and superior strength gains
Up to 30 g/day → Safe and well tolerated long-term with added cognitive benefits in healthy adults → Improvements in memory and attention
Older adults → Enhanced recall and mental performance at higher doses
Alzheimer's pilot → 20 g/day for 8 weeks increased brain creatine (~11%) and improved cognition
Pre-clinical AD data → Improved brain bioenergetics and reduced neurodegeneration markers
