People with dietary restrictions, such as vegans or vegetarians, may need a vitamin B supplement, particularly B12, which is found in animal products.
Older adults often have reduced stomach acid production, which can affect vitamin B absorption, increasing the need for supplements.
Pregnant or breastfeeding women may require additional B vitamins, like B9 (folate), to support fetal development and overall health.
Conditions like celiac disease or Crohn’s disease can impair nutrient absorption, potentially leading to a vitamin B deficiency.
Chronic alcohol consumption can interfere with vitamin B absorption, particularly B1 (thiamine), leading to deficiencies.
Excessive intake of certain B vitamins, particularly B6 and B12, can lead to nerve damage or other side effects, so proper dosage is important.
While supplements are beneficial for those with deficiencies, most people can get sufficient B vitamins from a balanced diet, including whole grains, meat, and dairy.
