B Vitamins: Benefits, Deficiency & Correct Dosage

What are B vitamins?

B vitamins are a group of eight water-soluble vitamins that perform numerous vital functions in the body. Since the body cannot store them (with the exception of B12), they must be supplied regularly through food or supplements. A deficiency can develop gradually and cause various symptoms.

The 8 B Vitamins at a Glance

Vitamin B1 (Thiamine)

Function: Essential for energy metabolism and nerve function. B1 helps the body convert carbohydrates into energy.

Deficiency Symptoms: Fatigue, concentration problems, muscle weakness, irritability.

Vitamin B2 (Riboflavin)

Function: Important for energy metabolism, cell function, and protection against oxidative stress.

Deficiency Symptoms: Cracked corners of the mouth, inflamed mucous membranes, light sensitivity.

Vitamin B3 (Niacin)

Function: Involved in over 200 enzymatic reactions. Important for energy production and DNA repair.

Deficiency Symptoms: Skin changes, diarrhea, confusion.

Vitamin B5 (Pantothenic Acid)

Function: Indispensable for the synthesis of coenzyme A, which is involved in energy metabolism.

Deficiency Symptoms: Rare. In case of deficiency: fatigue, insomnia.

Vitamin B6 (Pyridoxine)

Function: Central for amino acid metabolism, the formation of neurotransmitters (serotonin, dopamine), and immune function.

Deficiency Symptoms: Mood swings, anemia, weakened immune system.

Vitamin B7 (Biotin)

Function: Known as the "beauty vitamin" – important for healthy hair, skin, and nails.

Deficiency Symptoms: Hair loss, brittle nails, skin problems.

Vitamin B9 (Folic Acid/Folate)

Function: Essential for cell division and DNA synthesis. Especially important during pregnancy.

Deficiency Symptoms: Anemia, fatigue, elevated homocysteine.

Vitamin B12 (Cobalamin)

Function: Indispensable for blood formation, nerve function, and DNA synthesis.

Deficiency Symptoms: Fatigue, tingling in hands and feet, memory problems.

Who is at increased risk for B vitamin deficiency?

• Vegans and Vegetarians: Especially B12 deficiency
• Elderly People: Reduced absorption capacity in the gastrointestinal tract
• Pregnant and Breastfeeding Women: Increased need for folic acid and B6
• People with high stress: Stress increases the consumption of B vitamins
• Athletes: Increased energy metabolism requires more B vitamins

Why a B-Complex is useful

B vitamins work synergistically – they enhance each other's effects. An isolated deficiency of just one B vitamin is rare; a deficit of several B vitamins is more common. Therefore, nutritionists often recommend a complete B-complex instead of individual B vitamins.
