Curcumin itself is an "all-natural health care product" with no side effects. Except for pregnant women, lactating women, people with liver dysfunction and people taking anticoagulant drugs, it is recommended to take it for a long time for the best effect. Of course, products with high C3 curcumin content should be selected when purchasing, and the effect is better. For example, AB9 vitality C3 curcumin has more than 30%, and it was selected as the best curcumin health care product by the Hong Kong Health Industry Award last year.
