Can vitamin B6 be taken long-term?

　　B6 refers to vitamin B6. Long-term use of vitamin B6 is generally not recommended. Detailed analysis is as follows:

　　Vitamin B6 is a type of water-soluble vitamin that participates in various metabolic processes in the body, especially amino acid metabolism. A deficiency in vitamin B6 may cause seborrheic dermatitis, dry and cracked lips, and other symptoms. Short-term, appropriate supplementation of vitamin B6 is safe for most people, but excessive intake may lead to side effects.

　　Long-term excessive intake of vitamin B6 may result in various side effects, including peripheral neuritis, characterized by symptoms such as numbness and pain in the limbs; abnormal nerve sensations, such as unsteady gait and numbness in the hands and feet; gastrointestinal discomfort, such as nausea, vomiting, and loss of appetite; and drug dependency, which may affect the body's natural ability to synthesize vitamin B6. Additionally, excessive intake may interfere with the absorption and metabolism of other B-complex vitamins.

　　Therefore, when taking vitamin B6, it is essential to strictly follow the dosage recommended by a doctor and avoid exceeding the recommended amount to prevent the aforementioned adverse reactions. At the same time, it is also important to consume sufficient fresh vegetables and fruits in the daily diet.
