Early Warning Signs of Insufficient Vitamin B12 Levels ย 

Vitamin B12 deficiency can lead to a range of symptoms that should not be overlooked. ย 

One of the most common warning signs is fatigue and weakness, as B12 plays a crucial role in red blood cell formation and energy production.ย 

Up to 20% of older persons may lack this vitamin, according to a Journal of Nutrition, Health & Aging study.

Another significant warning sign is neurological problems, including tingling or numbness in the hands and feet, balance issues, and cognitive difficulties.ย 

A 2019 study in Frontiers in Neurology found that B12 deficiency can mimic the symptoms of neurological disorders like multiple sclerosis or dementia.

B12 is needed for appropriate digestion and food absorption, therefore some people may experience constipation, diarrhea, and loss of appetite.

Known physician and author of "How Not to Diet," Dr. Michael Greger stresses early B12 insufficiency testing and therapy. ย 

Due to the lack of animal-based B12 sources, vegetarians and vegans are at higher risk and should have regular blood tests.

Experts recommend taking a high-quality B12 supplement or eating B12-rich foods such fortified plant-based milk, nutritional yeast, and tempeh to prevent deficiency. ย 

Early detection and prompt treatment can help prevent long-term complications and improve overall health and well-being.
