Key Research Findings

Summaries of landmark peer-reviewed studies on creatine supplementation.

1. [1]

   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.

2. [2]

   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.

3. [3]

   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.

4. [4]

   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.

5. [5]

   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.

6. [6]

   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.

7. [7]

   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.

8. [8]

   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.
