Vitamin B and vitamin E can be taken together and will not affect its decomposition and utilization by the internal environment of the body. If you drink beverages containing caffeine and alcohol before taking vitamin B and vitamins, or take aspirin and other drugs, you cannot use vitamin B and vitamins immediately, otherwise the absorption of the vitamins will be affected, and blood vessel embolism will occur in serious cases. Before taking vitamin B, it is not recommended to drink beverages containing caffeine and alcohol, because such beverages will stimulate the nerves to induce the adrenal glands to secrete hormones, which will consume vitamin B in the body while also destroying the vitamin B that has just been consumed. Before taking vitamin E is not recommended to use aspirin, vitamin K and other drugs, because the role of vitamin E and aspirin is more similar, both play a role in reducing the viscosity of the blood, while taking vitamin K and vitamin B at the same time, will inhibit the agglutination of platelets, if they are already taking anticoagulant drugs, or before doing surgery, to immediately stop taking.
