What is Vitamin B6?
Vitamin B6 (pyridoxine hydrochloride) is a water-soluble vitamin present in a variety of food sources, such as cereal, vegetables, liver, meat, nuts, chickpeas, and eggs. Your health professional may recommend vitamin B6 if you don’t get enough vitamin B6 from your diet.
Vitamin B6 is most often used to treat and prevent vitamin B6 deficiency, but it can also treat certain anemias, high levels of homocysteine, and premenstrual syndrome. Vitamin B6 and doxylamine can be used to treat morning sickness. When taken with magnesium, it is possibly effective in decreasing the risk of kidney stones. It may also potentially help lower inflammation caused by rheumatoid arthritis.
Pyridoxine is one form of vitamin B6, and other forms include pyridoxal and pyridoxamine. In the human body, they are all considered to be equivalent. Other B vitamins include vitamin B1 (thiamin), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B7 (biotin), vitamin B9 (folate/folic acid), and vitamin B12 (cobalamin).

Important information about Vitamin B6
In the body, vitamin B6 is converted to the co-enzyme pyridoxal-5-phosphate, which is required for the metabolism of amino acids, carbohydrates, and lipids. Vitamin B6 is essential for hemoglobin formation to ensure red blood cells can effectively carry oxygen. It also has important roles in regulating the immune system and nervous system, including being involved in the production of several neurotransmitters.
Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide, before using vitamin B6. However, the following is a synopsis of the general guidelines for the use of vitamin B6:
Vitamin B6 can be in the form of tablets taken by mouth, or in the form of injectables, which are injected into a muscle or a vein through an IV. Do not give yourself this medicine if you are unsure how to use the injection and properly dispose of the injection supplies.
If you are taking vitamin B6 tablets, take them with food and water. Do not chew, crush, or break the tablet.
The most common side effects of vitamin B6 include:
- Abdominal pain
- Headache
- Heartburn
- Loss of appetite
- Nausea
- Somnolence
- Vomiting
- Mild numbness or tingling
Some individuals may experience serious side effects while using vitamin B6. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:
- Peripheral neuropathy may occur at high doses (>500 mg per day). Signs of peripheral neuropathy include decreased sensation to touch, temperature, and vibration, loss of coordination, and numbness in your feet or around your mouth.
These are not all of the possible side effects of vitamin B6. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.
Before starting vitamin B6, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including whether you have:
- Parkinson's disease, and you are being treated with levodopa
Hypersensitivity to vitamin B6 (pyridoxine) or any component of the formulation.
Vitamin B6 is well absorbed because it is water-soluble, but it may take a couple of weeks for you to feel better. The time it takes to work fully will depend on the severity of the deficiency. For morning sickness, it may take up to one week for it to start working.
When vitamin B6 is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:
- Levodopa
- Phenobarbital
- Primidone
- Phenytoin
Vitamin B6 supplement doses will vary depending on the manufacturing company. Over-the-counter vitamin B6 products usually contain 50 mg or 100 mg per tablet. Vitamin B6 can also be found in vitamin B complexes and general multivitamin formulations.
The daily recommended dietary allowance (RDA) of vitamin B6 is 1.3 mg for males and females 19-50 years of age. Do not take daily doses higher than what your healthcare professional recommends due to the increased risk of toxicity.
Store the medication in a closed container at room temperature, away from heat, moisture, and direct light. Keep out of reach of children.
Multiple pharmaceutical companies manufacture vitamin B6.
Vitamin B6 is the generic version.
You should take vitamin B6 at the dose and length of time recommended by your healthcare provider. Do not stop taking vitamin B6 without consulting your healthcare provider because doses >200 mg per day may cause dependence and withdrawal.
Vitamin B6 is likely safe for pregnant women when taken orally and appropriately. It can also be used for morning sickness, but it should not be used long-term or without medical supervision.
