Suspecting a vitamin B deficiency? Watch for these telltale signs in your body.
What happens when you're low on vitamin B? B vitamins act as your body's energy boosters and mood supporters. A shortage can leave you feeling off, drained, and uncomfortable in your own skin.
For instance, vitamin B6 is essential for producing brain neurotransmitters like serotonin. Insufficient B6 may lead to depression and poor sleep. Prolonged deficiency risks anemia, nerve issues, and weakened immunity.
Vitamin B1 (thiamine), the B-group's energy powerhouse, also supports nerve function. Lack of it causes weakness, fatigue, anxiety, mood swings, and depression.
Vitamin B12 deficiency brings muscle cramps, extreme tiredness, mouth sores, heart palpitations, nausea, loss of appetite, tingling in hands and feet, and tinnitus. For detailed insights, visit Stichting B12 Tekort.
In the Netherlands, B vitamin deficiencies are uncommon but affect certain risk groups. Poor absorption or medications can trigger them, often impacting multiple B vitamins at once.

Who is at risk for vitamin B deficiency? Certain groups face higher chances and may benefit from targeted supplementation.
Heavy drinkers
More than three daily glasses for women or four for men qualifies as heavy drinking. Alcohol impairs vitamin absorption, ramps up usage during processing, and often pairs with poor diets—leading to shortages in B1, B3, and B12.
Vegans Without animal products like meat, fish, dairy, or eggs—prime B12 sources—vegans commonly lack this vitamin.
People over 60
Aging reduces intestinal absorption of B6, B12, and folic acid. Lower stomach acid further hinders B12 uptake.
Other risks Gastric conditions like Crohn's disease or long-term acid inhibitors also block B12 absorption.
If concerned, consult your doctor for blood tests to confirm.
Do you need supplements?
B vitamins work synergistically—a surplus of one demands balance from others. Per the Nutrition Centre, a varied diet suffices for most, unless you're at risk. Patricia Schutte notes: 'Unhealthy eating means excess calories, fats, and low fiber—supplements won't fix that. Whole foods offer protective benefits pills can't match.' Opt for supplements at or below RDA to avoid harms like nerve damage from excess B3, B6, or folic acid.
