Notes
- Modest effect — an increase of ~50–100 kcal/day in basal energy expenditure.
- It may cause a mild warm sensation in the stomach — take it with food if your stomach is sensitive.
- Capsifen® is an encapsulated form that reduces the oral "burning" sensation.
- Do not take it close to bedtime — it may interfere with sleep.
Synergy with other supplements
- It pairs well with ALCAR + black coffee in the morning before a fasted workout (Z2).
- It works no miracle on its own — the real engine is diet + training.
