Creatine is the number-one complement for bettering efficiency within the fitness center.
Research present that it will possibly enhance muscle mass, energy and train efficiency (1, 2).
Moreover, it supplies a variety of different well being advantages, equivalent to defending in opposition to neurological illness (3, 4, 5, 6).
Some individuals consider that creatine is unsafe and has many unintended effects, however these are usually not supported by proof (7, 8).

Regardless of the potential advantages of creatine for treating neurological illness, most present analysis has been carried out in animals.
Nonetheless, one six-month examine in kids with traumatic mind harm noticed a 70% discount in fatigue and a 50% discount in dizziness (40).
Human analysis means that creatine may also support older adults, vegetarians and people liable to neurological illnesses (39, 41).
Vegetarians are inclined to have low creatine shops as a result of they don’t eat meat, which is the primary pure dietary supply.
In a single examine in vegetarians, supplementing precipitated a 50% enchancment in a reminiscence check and a 20% enchancment in intelligence check scores (21).
Though it will possibly profit older adults and people with lowered shops, creatine reveals no impact on mind perform in wholesome adults (42).
Different Well being Advantages
Analysis additionally signifies that creatine could (5, 27, 43, 44, 45, 46, 47, 48):
