What can you tell me about Creatine supplementation?

Creatine supplementation has been discussed in multiple episodes of the Huberman Lab, providing insights on its various benefits and uses:

• Depression: Creatine can augment the response to selective serotonin re-uptake inhibitors (SSRIs) and improve the effectiveness of SSRIs in treating major depressive disorders. It also enhances activity in the forebrain, which may lead to plasticity changes associated with a shift from negative to positive mood 1.
• Dosage: The standard dosage is about 3-5 grams per day, adjusted according to physical size. Larger individuals might require more, and the timing of ingestion is considered irrelevant 2.
• Traumatic Brain Injury (TBI): In cases of TBI, creatine supplementation significantly reduced the frequency of headaches, dizziness, and fatigue. A pilot study indicated dramatic effects, suggesting potential benefits in TBI treatment 3.

  Creatine and Depression

  Andrew Huberman

  Andrew discusses the potential benefits of creatine supplementation for treating depression, including its ability to enhance the response to SSRIs and increase activity in the forebrain phosphocreatine system, which may lead to changes in neural circuits and a shift from negative to positive mood.

• Brain Function: Creatine is believed to play a role in enhancing certain brain functions, possibly providing cognitive benefits such as improved memory and executive function, and assisting with some forms of mild depression 4.
• Fitness and Muscle Performance: It can improve muscle performance and strength since it brings more water into muscles, which is why many people take it daily, typically post-workout, but it can be taken at any time of day 5.

It's important to consult with a healthcare professional before starting any new supplementation regimen, particularly in the context of health conditions like TBI or mood disorders 6.

There is no mention of significant risks associated with daily creatine supplementation specifically for enhancing exercise performance in the clips retrieved from the Huberman Lab. However, Andrew Huberman does discuss dosage and potential gastric distress in some people. He suggests that while his stomach tolerates up to 15 grams of creatine per day without issue, some individuals may experience gastrointestinal discomfort and may need to take creatine with food or gradually increase their intake to reduce this distress. He also mentions that some people may avoid creatine due to concerns it might cause hair loss, but clarifies there is a lack of data supporting that idea 1.

As always, it is recommended that individuals consult with a healthcare professional before starting any supplementation regimen, particularly those with pre-existing health conditions or concerns about potential side effects.
