I have been spending time organizing my medications and vitamins. I figured this was a good time to mention the importance of vitamin B12. Previous research indicated B12 and folic acid, another B vitamin helps maintain our brain and might help fend off Alzheimer's disease.
The lack of B12 could diminish cognitive function, so make sure you are eating properly and if you are a vegan, consider sublingual B12 supplements. Try to remember that older people have trouble absorbing B12.
B12 can be found in oysters and other mollusks, fish, meat, eggs and milk. You can take sublingual B12 supplements which dissolve under the tongue for better absorption. There are other factors to consider, people who don't make enough stomach acid or intrinsic factor become anemic and need to have B12 shots or large amounts of vitamin B12 as pills or tablets. I remember my PCP offered me B12 injections. They can be expensive which is why I decided to change my diet and take B12 supplements.
Lastly, researchers found that people with depression responded better to anti-depressants if they had higher blood levels of vitamin B12. Vitamin B12 is also important for our metabolism and central nervous system.
I hope and pray this information has helped someone today.
