ISSN-Based Dosage Formulas
Maintenance Dose
bodyweight (kg) × 0.03g
Example: 80kg → 2.4g/day
Source: ISSN Position Stand, Kreider et al. 2017
Loading Phase
bodyweight (kg) × 0.3g ÷ 4 doses
Example: 80kg → 6g × 4/day for 7 days
Source: ISSN Position Stand, Kreider et al. 2017
Creatine HCl Dose
monohydrate dose × 0.5
Example: 80kg → ~1.2g/day

Water Intake
2500ml + (500ml × dose/5g)
Example: 5g dose → 3000ml/day minimum

Key Research Findings
Summaries of landmark peer-reviewed studies on creatine supplementation.
Kreider RB, et al. J Int Soc Sports Nutr. 2017;14:18
Creatine is the most effective ergogenic nutritional supplement for increasing high-intensity exercise capacity and lean body mass during training.
Rawson ES, Volek JS. J Strength Cond Res. 2003;17(4):822–831
Creatine supplementation combined with resistance training produces greater muscle strength and weightlifting performance than training alone.
Lanhers C, et al. Sports Med. 2017;47(1):163–173
Meta-analysis of 22 studies: creatine supplementation significantly improves upper limb strength performance in resistance training.
Poortmans JR, Francaux M. Med Sci Sports Exerc. 1999;31(8):1108–1110
Long-term creatine supplementation (up to 5 years) does not impair renal function in healthy athletes.
Antonio J, Ciccone V. J Int Soc Sports Nutr. 2013;10:36
Post-workout creatine supplementation produced greater increases in lean mass and strength than pre-workout timing over 4 weeks.
Smith-Ryan AE, et al. Nutrients. 2021;13(3):877
Creatine supplementation is safe and beneficial for women across all life stages, including improvements in muscle strength and cognitive function.
Green AL, et al. Am J Physiol. 1996;271(5):E821–826
Co-ingestion of creatine with carbohydrate increases skeletal muscle creatine accumulation by ~60% compared to creatine alone.
Hultman E, et al. J Appl Physiol. 1996;81(1):232–237
Loading protocol (20g/day for 6 days) rapidly saturates muscle creatine to the same level as 28 days of low-dose supplementation.
Common Myths — Debunked by Research
Myth
Creatine damages kidneys
Fact
No evidence in healthy individuals. Multiple long-term studies confirm renal safety at recommended doses.
Myth
Creatine causes hair loss
Fact
One small study found elevated DHT (not hair loss). No study has ever confirmed creatine causes hair loss.
Myth
Creatine is a steroid
Fact
Creatine is a naturally occurring compound in red meat. It has no hormonal activity and is legal in all sports.
Myth
Everyone should take 5g
Fact
Dose should be based on body weight (0.03g/kg). A 55kg person needs ~1.65g; a 100kg person needs ~3g.
Myth
Creatine causes dehydration
Fact
Studies show creatine may improve hydration. Dehydration risk only exists if water intake is insufficient.
Myth
You need to cycle creatine
Fact
No scientific basis for cycling. Continuous use is safe and maintains consistent muscle saturation.
Creatine Forms — Quick Comparison
| Form | Daily Dose | Loading Phase | Research Level | Cost | Best For |
|---|---|---|---|---|---|
| Monohydrate | 3–5g (0.03g/kg) | Optional | Extensive (30+ yrs) | Lowest | Most people |
| Micronized | 3–5g (0.03g/kg) | Optional | Same molecule as mono | Low | Sensitive stomachs |
| Creatine HCl | 1–2g (0.015g/kg) | Not needed | Growing | Moderate | Low GI tolerance |
| Buffered (Kre-Alkalyn) | 3–5g | Not needed | Limited | High | No proven advantage |
