Kola nut is the seed of the kola tree, native to West Africa. The seed provides about 2 to 4% caffeine by weight. Its stimulant strength lands closer to coffee than to other cola-derived products.
People take kola nut to support energy and focus, and to reduce fatigue. They dose it in the morning or early afternoon to avoid disrupting sleep.
Too much can cause jitteriness, insomnia, or a fast heartbeat. Its caffeine may interact with stimulants and blood pressure medications. Talk to a healthcare professional before use.
