"No crash" is a common claim in this category — worth understanding what actually makes it true, rather than taking the phrase at face value.
Why caffeine source matters here
Slow-release caffeine sources like Guarana are traditionally associated with a more gradual energy curve than a single concentrated caffeine dose, which may explain why some people notice less of a sharp drop-off.
What still matters regardless of source
Total caffeine amount, individual sensitivity, and timing (earlier in the day vs. late) all still affect how a "no crash" formula actually feels — the ingredient source is one factor among several.
💊 Medication note: Chromium may affect blood sugar, and Green Tea/Guarana contain caffeine. If you have diabetes, take blood-sugar or heart medication, or are caffeine-sensitive, talk to your doctor before use.
