Is there anything unhealthy or dangerous about taking creatine?

The discussions on Huberman Lab regarding creatine address some common concerns and potential side effects associated with its use. Here are the key insights:

1. Hair Loss: Andrew Huberman and Dr. Kyle Gillette discussed the myth that creatine might increase hair loss due to its potential to slightly raise dihydrotestosterone (DHT) levels. However, they emphasize that creatine does not increase androgen levels to abnormal heights and should not significantly contribute to hair loss [chunk_57547].

2. Water Retention: Creatine can cause an increase in body weight due to water retention in muscles, which some may perceive as a drawback. This is usually not the same as subcutaneous water retention (bloating) but rather water stored within muscle tissues [chunk_1642914].

3. Gastrointestinal Issues: Some individuals may experience stomach discomfort when taking creatine, particularly if they consume higher doses. It's suggested to start with a lower dose and gradually increase it, or take it with food to mitigate stomach issues [chunk_127145].

4. Safety: Overall, creatine is considered safe and effective for various benefits, including for muscle growth and cognitive support. However, anyone planning to take it should tailor the dosage to their body weight and consult with a healthcare provider, especially if there are any underlying health concerns [chunk_56904].

On balance, while there are some potential side effects, creatine is generally regarded as a safe supplement when used appropriately.
