Vitamin B6 is an essential substance for fat and sugar metabolism in the human body. There is generally no clear rule that vitamin B6 cannot be taken at night, but the time and dosage of the medication needs to be decided by the doctor according to the condition, and patients are not recommended to adjust the dosage and the time of taking the medication by themselves. Vitamin B6 prevents damage to the arterial lining by promoting protein metabolism and avoiding causing deposits of cholesterol and triglycerides in the blood on the vessel walls. At the same time, vitamin B6 can bind to the clotting substances on the platelet surface, preventing platelet aggregation and prolonging clotting time, thus inhibiting thrombosis and preventing atherosclerosis. In addition, vitamin B6 has the effect of preventing diabetes, mental disorders, pregnancy vomiting and eliminating bad breath, while helping to stabilize estrogen metabolism in women. Vitamin B6 is also currently used clinically to treat mouth ulcers, gestational diabetes, anemia, and isoniazid poisoning resuscitation, but patients need to be properly medicated under medical supervision.
