B vitamins – the "invisible guardians" of health, 90% of people are deficient in them!
2025-11-28
Do you often feel tired and weak, experience low mood, mouth ulcers, and dry hair? Are you trying to maintain your health, but sub-health conditions still linger?
Don't ignore these warnings; your body may be sending you a message: you may be deficient in B vitamins!
Nutritional surveys show that over 90% of Chinese people are deficient in B vitamins to varying degrees. This is not an exaggeration, as B vitamins are among the nutrients most easily depleted by modern lifestyles.

Nutritional surveys show that over 90% of Chinese people are deficient in B vitamins to varying degrees. This is not an exaggeration, as B vitamins are among the nutrients most easily depleted by modern lifestyles.
Why are B vitamins considered a contributing factor to chronic diseases?
B vitamins act like spark plugs in a health engine, collectively governing energy metabolism and nervous system function. Long-term deficiency can fundamentally undermine our health and is closely linked to the development of various chronic diseases:
**Cardiovascular Disease:** Deficiencies in folic acid (B9), vitamin B6, and B12 can lead to elevated homocysteine levels, a crucial cardiovascular risk factor that directly damages the vascular endothelium, independent of cholesterol.
**Nervous System Disorders:** Anxiety, depression, insomnia, memory loss, and even cognitive impairment are associated with insufficient support from B vitamins (especially B1, B6, B9, and B12) for neurotransmitter synthesis and myelin sheath health.
**Diabetes and Complications:** B vitamins (such as B1 and B7) play a key role in carbohydrate and fat metabolism. Diabetic patients commonly lack B1, and this deficiency can exacerbate complications such as neuropathy.
**Anemia:** A deficiency in folic acid (B9) and vitamin B12 can lead to megaloblastic anemia, causing paleness and weakness.
The B vitamins are a "golden team," working together and none can be missing. Supplementing with large amounts of one vitamin alone may cause a relative deficiency of the others. Therefore, a comprehensive understanding and balanced supplementation are crucial.
B Vitamin Family Member Profile: Each Playing a Role in Protecting Health
Let's get to know each core member of this family:
Table of Contents
1. Vitamin B1 (Thiamine)
2. Vitamin B2 (Riboflavin)
3. Vitamin B3 (Niacin)
4. Vitamin B5 (Pantothenic Acid)
5. Vitamin B6 (Pyridoxine)
6. Vitamin B7 (Biotin)
7. Vitamin B9 (Folic Acid)
8. Vitamin B12 (Cobalamin)
1. Vitamin B1 (Thiamine) — 1. **Vitamin B1 (B1)** – **Energy Motor**
**Core Function:** Primarily responsible for carbohydrate metabolism, converting food into energy needed by the body. Essential for the normal function of nerve tissue and the heart.
**Deficiency Signs:** Fatigue, loss of appetite, low mood, numbness in the limbs (beriberi is a severe form of B1 deficiency).
2. **Vitamin B2 (Riboflavin)** – **Skin Repairer**
**Core Function:** Participates in energy metabolism, maintains the health of skin, mucous membranes, and hair follicles, and promotes growth and development. A "beauty protector."
**Deficiency Signs:** Angular cheilitis, cheilitis, glossitis, seborrheic dermatitis, photophobia, and congestion.
3. **Vitamin B3 (Niacin)** – **Cholesterol Buster**
**Core Function:** Participates in energy metabolism, DNA repair, and synthesis. Plays a positive role in lowering "bad" cholesterol (LDL) and triglycerides, and raising "good" cholesterol (HDL).
**Deficiency Signs:** Rough skin, pigmentation, indigestion, pellagra (a typical deficiency symptom).
4. Vitamin B5 (Pantothenic Acid) – “Stress-Resistant Vitamin”
Core Functions: Participates in the metabolism of almost all nutrients in the body, is key to the synthesis of **Coenzyme A**, and is crucial for adrenal function and the secretion of stress hormones.
Deficiency Signs: Fatigue, sleep disorders, tingling in hands and feet (relatively rare, but increased due to stress).
5. Vitamin B6 (Pyridoxine) – “Mood Regulator”
Core Functions: Participates in amino acid metabolism, hemoglobin synthesis, and the production of neurotransmitters (such as serotonin – the “happy hormone”). Plays an important role in regulating mood and relieving morning sickness.
Deficiency Signs: Depression, insomnia, anemia, peripheral neuropathy, worsening morning sickness.
6. Vitamin B7 (Biotin) – “Beauty Expert”
Core Functions: Promotes the metabolism of fats and proteins, crucial for maintaining the health of **skin, hair, and nails**. A well-known nutrient for “preventing hair loss and promoting hair growth.”
Deficiency Signs: Hair loss, dry hair, dry skin, brittle nails.
7. Vitamin B9 (Folic Acid) – “Guardian of Life”
Core Functions: Participates in cell division and growth, crucial for **fetal neural tube development**, and is an essential vitamin for women trying to conceive and during pregnancy. It also lowers homocysteine levels, preventing anemia.
Deficiency Signs: Megaloblastic anemia, weakness, oral ulcers, neural tube defects in the fetus (early pregnancy).
8. Vitamin B12 (Cobalamin) – “Neurological Protector”
Core Functions: Maintains nervous system health, promotes red blood cell production, and works synergistically with folic acid to lower homocysteine levels. **Vegetarians are highly susceptible to deficiency**, as it is primarily found in animal-based foods.
Deficiency Signs: Pernicious anemia, memory loss, nerve damage (numbness, tingling), fatigue.
Part Two: How to Supplement B Vitamins?
1. Prioritize Dietary Supplementation:
Whole Grains as the Mainstay: Eat more brown rice, oats, millet, etc. (Refined rice and white flour lose a significant amount of B vitamins).
High-Quality Protein: Consume moderate amounts of lean meat, animal liver, and eggs.
Colorful Fruits and Vegetables: Dark green leafy vegetables (rich in folic acid), legumes, nuts, and seeds.
2. Change Unhealthy Lifestyle Habits:
Limit Alcohol: Alcohol metabolism depletes B vitamins significantly.
Reduce Late Nights: Stress and mental tension increase B vitamin consumption.
Avoid Overcooking: B vitamins are mostly water-soluble and sensitive to light and heat; dishes should not be soaked for extended periods or fried at high temperatures.
3. Choose Supplements Scientifically:
For individuals whose diet cannot be corrected, whose vitamin deficiencies are high, or who already exhibit obvious deficiency symptoms, it is recommended to choose a **complex B vitamin supplement** under the guidance of a doctor or nutritionist. This is safer and more effective than single-vitamin supplements.
The B vitamins, this large and intricate family, are the cornerstone of our vitality. Don't ignore this "hidden" health vulnerability any longer! Starting today, pay attention to your meals, listen to your body, supplement your B vitamin intake, lay a solid foundation for your health, and stay away from chronic diseases!
