Who Can Benefit from B12 Injections?
Vitamin B12 plays a role in a wide variety of functions in your body. Read on to learn how having low levels of vitamin B12 can cause problems and how B12 injections can help.

Your body needs certain vitamins and minerals to function correctly. One of these crucial vitamins is B12, most of which we get through eating meat.

As we age, though, our bodies can begin to lose the ability to absorb vitamins effectively. This can lead to a deficiency in vitamin B12 levels, for instance, which can lead to a number of health issues.

This deficiency can be corrected with regular B12 injections from Pamela Phillips, Ph.D., FNP-C, and her team at Phillips Family Medical in DeSoto, Texas. In this blog, she explains some of the problems people with vitamin B12 deficiencies can face and how B12 injections can help.

Weight problems

Research shows that people who have low B12 levels may be more likely to deal with obesity.

Furthermore, if you have a slow metabolism, this can lead to weight gain and fatigue. However, injections of vitamin B12 can stimulate your metabolism, which can help you burn calories quicker and convert food into energy more efficiently.


Vitamin B12 is important for brain function. Low levels of B12 can affect neurotransmitters, such as serotonin and dopamine, which help regulate mood. A vitamin B12 deficiency can start you on the path to depression and anxiety or exacerbate the conditions. If you’re beginning to feel anxious or down, an injection of vitamin B12 may boost your mood.

Immune system issues

Vitamin B12 plays an important role in the production of white blood cells, which are an essential part of your body’s defense system to fight off infections and keep your immune system in good working order. If you find yourself getting sick more often than normal, a B12 injection may give your immune system the jumpstart it needs.

Sleep problems

An amino acid in your body called tryptophan helps you fall asleep at night. It’s also found in turkey, which is why you may feel sleepy after that Thanksgiving meal. Vitamin B12 plays a big role in the production of tryptophan, so if your B12 levels are low, your sleep may be more restless. However, getting injections of vitamin B12 may help you sleep soundly again.

If you’re dealing with any of the issues we discussed, you may want to have your vitamin B12 levels checked. If they’re low, our team can discuss giving you injections of vitamin B12. To learn more, call 972-861-1151 or book an appointment online with Phillips Family Medical today.
