If you are already on keto and someone pitches a coffee additive powder (Java Burn in particular), a calm label-first pass beats hype:

• Read the label yourself: green tea extract, L-carnitine, chromium, etc. — none of these replace a calorie deficit or sleep.
• Soft claims only: metabolism support language is marketing; expect modest, individual results at best.
• Cost check: multi-bottle packs vs making black coffee + protein/fat that already fits your macros.
• Skip miracle before/after photos and anonymous “reviews.”

Happy to answer label questions. Clinician first if you have a condition or take meds.
