The weight loss principle of L- arabinose powder is mainly biological mechanism. Sucrose will be decomposed by combining with sucrase in the body, absorbed and utilized by the human body, and the excess will be converted into fat accumulation. The existence of L- arabinose powder can compete with sucrose, thus reducing the human body's intake of sucrose. Japanese research shows that adding 4% L- arabinose to sucrose can inhibit 70%-80% absorption. A lot of fat in our body is converted from sugar, so L- arabinose powder can lose weight. If my answer can help you, please adopt it.
