• Use the drink moderately (for example, one to two cups per day) and preferably before meals to support metabolism and satiety.

• Choose high‑quality black beans (preferably green‑core variety), avoid moldy or old beans, and avoid over‑roasting (which may reduce beneficial compounds or cause burnt taste) and avoid overconsumption.

• Pregnant women, children, or users of certain medical conditions should consult a healthcare professional before using this as a routine beverage.
