Pharmacist tips for Vitamin B Complex

pharmacist
  • Many multivitamins already contain several B vitamins. Make sure you check how much you should be taking with your provider or pharmacist to avoid side effects from taking too much.
  • Make sure to tell your provider or pharmacist about all of the medications you're taking, because Vitamin B Complex might interact with your certain medications.
  • Keep your Vitamin B Complex bottle in a cool, dry place at room temperature. Don't store it in your bathroom because the moisture in the air could affect how well the product works.
  • Don't use Vitamin B Complex after the expiration date on the package. It might not work as well for you if you use it beyond that date.
  • Keep Vitamin B Complex stored in its original container. Exposure to light can destroy the vitamin B2 component.

Risks and warnings for Vitamin B Complex

Vitamin B Complex can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Risk of too much B vitamins

  • Risk factors: Taking more than the recommended dose

It's unlikely to take too much B vitamins if you follow the instructions on your Vitamin B Complex package. B vitamins are water-soluble, meaning your body can get rid of extra amounts through the urine. But if you take very high doses over a long period of time, it's possible to take too much Vitamin B Complex, leading to severe side effects from specific vitamins, like vitamin B3 or vitamin B6. Since other OTC supplements contain B vitamins, always check with your provider or pharmacist to make sure you're not taking too much.
