4 Things A Vitamin B12 Deficiency Can Lead To
B vitamins help support adrenal function, help calm and maintain a healthy nervous system, and are all necessary for key metabolic processes. Vitamin B12, also known as cyanocobalamin, is necessary for DNA synthesis and affects the development of red blood cells, normal myelination (insulation) of nerve cells, and the production of neurotransmitters which are essential to the nerves’ messaging system including an impact on supporting mental health and mood.
Deficiencies of B12 can lead to:
- Memory loss
- Confusion
- Fatigue
- Dementia
Know that commonly used medications like the diabetes drug metformin, birth control pills and acid suppressing meds can deplete the body of B12, promoting these concerning side effects. If you are on these medications, work with your provider to monitor blood levels or consider supplementation.
Animal-derived foods, including dairy, eggs, meat, fish and poultry are the only food sources of B12, so this important vitamin is often deficient in vegan diets. Those with weaker digestive health may be at risk as well. Good sources are clams, herring, cooked oysters and wild Alaskan salmon.
These recipes feature foods that provide B12:
To help meet daily needs, Dr. Weil recommends a B-complex supplement that contains a full spectrum of B vitamins, including thiamine, B12, riboflavin and niacin. Be aware though that so often a B complex provides only a moderate amount of B12, and an additional supplement may be necessary. It is always a good idea to have your provider monitor vitamin B12 levels in blood to ensure you are getting enough, particularly if you are on any of the medications listed above.
