In this article, we’ll explore the top 3 Vitamin B deficiency FAQs, including does Vitamin B deficiency cause hair loss, can a Vitamin B deficiency cause weight gain, and can Vitamin B deficiency cause anxiety?
What Causes Vitamin B Deficiency?
The causes of Vitamin B deficiency can vary. Many B Vitamins, especially Vitamin B12, are prevalent in animal sources and B12 in particular requires a special protein, called intrinsic factor, to be properly absorbed during digestion. B12 can't be synthesized within the body, leaving diet as the only source of this essential nutrient. As a result, diets limited in meat, dairy, eggs, and seafood, absorption issues resulting from age, intrinsic factor deficiency, and other illnesses including SIBO, Grave’s disease, and Addison’s disease, can all predispose you to B12 deficiency.

Does Vitamin B Deficiency Cause Hair Loss?
Get the facts: does Vitamin B deficiency cause hair loss? Yes! Almost all B Vitamins are involved in skin and hair health. As with many vitamins and minerals, nutritional deficiencies in B Vitamins, especially B2 (riboflavin), B3 (niacin), B7 (biotin), B9 (folate), and B12 (cobalamin), can cause brittleness, breakage, and hair loss.
Can A Vitamin B Deficiency Cause Weight Gain?
Wondering if a Vitamin B deficiency can cause weight gain? Actually, it's quite the opposite. In many cases, Vitamin B deficiency is associated with weight loss. Part of this is because B Vitamins play an essential role in macronutrient absorption (carbs, fats, proteins). Additionally, Vitamin B deficiencies often interfere with appetite and digestion, leading to nausea, bloating, diarrhea, and other symptoms which can cause you to eat less.
Can Vitamin B Deficiency Cause Anxiety?
Feeling anxious? It might be a Vitamin B deficiency. The B Vitamins are essential for synthesizing neurotransmitters, including acetylcholine and serotonin. Crucially, serotonin is associated with feelings of emotional stability, happiness, and calm. Shortages of this neurotransmitter caused by low B Vitamins could result in anxiety, depression, and emotional lability.
