9. Cancer protection
Studies show that Vitamin B12 may help protect us against some of the deadliest forms of cancer. These include prostate, lung, breast, cervical and colon cancers, which are all hormonally induced cancers. Vitamin B12 is thought to help prevent these types of cancer because it helps to reduce damage to chromosomes. Chromosomes play a part in helping the cells to divide and replicate accurately. If they become damaged the cell will produce a damaged version of itself and this can lead to the new cell eventually becoming cancerous.
