Could you provide some scientific research on creatine supplementation?
Sources:
Here are some insights from scientific research on creatine supplementation, as discussed on the podcast:
-
Cognitive and Mental Health Benefits: Creatine monohydrate has been highlighted for its potential benefits beyond muscle performance, including cognitive enhancement and mood regulation. Studies have shown that creatine can support brain health by improving the phosphocreatine system in the forebrain, which may help with mood disorders like depression by influencing NMDA receptor activity that is crucial for neuroplasticity 1 2.
-
Increased Efficacy of Antidepressants: A study published in the American Journal of Psychiatry found that creatine supplementation could enhance the effectiveness of SSRIs (selective serotonin reuptake inhibitors) in women with major depressive disorder. This suggests that creatine might help reduce the required dosage of these medications or improve their efficacy 1.
-
Neurological Benefits: mentioned that creatine's role in the brain extends to potentially improving conditions like traumatic brain injury (TBI), where it might help reduce symptoms like headaches, dizziness, and fatigue. This is due to creatine's involvement in energy production and calcium regulation in neurons, critical factors disrupted by TBI 3.
-
Physical Performance and Muscle Health: Creatine is well-known for enhancing muscle strength and power due to its involvement in the energy production cycle in muscles. Additionally, creatine usage may also be linked to improved bone health and metabolic functions 4 5.
Overall, while more research is needed to fully understand the extent of creatine's benefits, existing studies suggest it is a valuable supplement for both physical and cognitive health. Always consider consulting a healthcare provider before starting any new supplement regimen.
