B vitamins are a group of vitamins essential for good health. Your body can't store B vitamins for long, so you have to get them every day through what you eat and drink.1. What are B vitamins?
B vitamins are a water-soluble vitamin that plays an important role in cell metabolism and red blood cell synthesis. Although these vitamins share the same name (vitamin B1, B2, B3,...), they are chemically distinct compounds that often coexist in the same foods.Vitamin B complex supplements include all the essential B vitamins in one pill. Some contain 100% of the recommended daily amount of B vitamins (RDA). Many people get all of the B vitamins they need from a varied, healthy diet, but others get their B vitamins from supplements.
2. The role of vitamin B in health
B vitamins help the body convert food into energy (metabolism), create new blood cells, and maintain skin cells and connective tissues in the body.There are eight types of B vitamins, each with its own function: Thiamin (vitamin B1), Riboflavin (vitamin B2), Niacin (vitamin B3), pantothenic acid (vitamin B5), Vitamin B6, Biotin (vitamin B7), Folate ( vitamin B9), vitamin B12.
All of these are called vitamin B complexes. B vitamins often coexist in the same food. Many people can get enough of the B vitamins they need by eating a variety of nutrient-dense foods. However, people who have difficulty consuming such foods can use supplements.
People can develop a vitamin B deficiency if they don't get enough vitamins from their diet or supplements. They can also become deficient if their bodies cannot properly absorb nutrients or if their bodies get rid of too many of them due to certain health conditions or certain medications. Here, we will learn about some common drug interactions when using B-complex vitamins.

What you should do about this interaction: Contact your healthcare professionals (doctor or pharmacist) about taking these two medicines together.

3.4. Interaction with Tetracyclines Tetracyclines is an antibiotic used to treat certain infections such as acne, cholera, Brucella, syphilis,...

When these two drugs are taken together, your body may not be able to process the antibiotic properly. The level of the antibiotic in your blood can drop and decrease its ability to treat an infection.
What you should do about this interaction: Contact your healthcare professionals (doctor or pharmacist) as soon as possible about taking these two medicines at the same time.
