Things you should know about B Vitamins

Published: 26 Feb 2020

As part of our vitamin series, this week we’ve focused on Vitamin B.  There is a lot of chatter in cancer and chemo online forums about B Vitamins.  B Vitamins are known to help with a wide variety of conditions including migraines, depression, anxiety, menopause symptoms, improving skin, hair and nails, immune system and energy levels. With all these benefits no wonder people reach for the B supplement tablets but should you take them during cancer treatment? 

Most people who have a healthy and varied diet will consume all the B vitamins they need without the need for additional supplements.  However, one of the side effects of cancer treatment is a lack of appetite and perhaps not eating enough of all the healthy things your body needs. This means your reserves of vitamins, including Vitamin B, can be depleted.  

You might have been told by well-meaning friends and family to take a B vitamin or a multi-vitamin tablet to top you up, but be careful!  Vitamin supplements, that are normally considered perfectly safe, might not be when you have cancer or are undergoing treatment. In particular, there is evidence that some B vitamin supplements should not be taken as they can intensify or weaken the effects of chemotherapy drugs.  

So, before you reach for any vitamin supplements you must speak with your doctor or medical specialist first.  And if you are already taking any supplements – inform your doctor.   

What are B Vitamins

B vitamins help the body convert food into energy (metabolism), create new blood cells, and maintain healthy skin cells, brain cells, and other body tissues.  There are 8 B vitamins in total, each one playing a vital part in keeping the body functioning. 

Where do B Vitamins come from?

People can usually get all the B vitamins that they need from a balanced healthy omnivorous, vegetarian, or vegan diet. However, animal products are a major source of B vitamins, so people following restricted diets should take extra steps to ensure that they are eating the right foods. In particular, chemo patients on a vegan diet should endeavor to check out food high in Vitamin B (and other essential vitamins and minerals) and ensure they're on the menu. 

Some of the best food sources of B vitamins include:

If you have cancer and are undergoing treatment, you should try to get al the B vitamins you need by eating a variety of healthy foods. However, if you believe you have any B Vitamin deficiency and it’s affecting your health, see your doctor and ask to have your vitamin levels tested. 

Above all, even if you think you need them - do not take any Vitamin B supplements before consulting with your medical team.
