✅ What Is Vitamin B2?

Vitamin B2 is a water-soluble B vitamin involved in multiple metabolic processes. Like all B vitamins, it's not stored well in the body, so you need to consume it daily through diet or supplements.

It acts as a coenzyme in reactions that turn carbohydrates, fats, and proteins into energy.

🔬 What Does B2 Do in the Body?

⚡ 1. Energy Production

• Essential for converting nutrients into ATP (cellular energy)

• Supports the function of enzymes in the Krebs cycle

🧬 2. Cell Growth & Repair

• Helps maintain healthy skin, nails, and hair

• Supports tissue healing and antioxidant activity

👁️ 3. Eye & Vision Health

• Important for corneal health

• May help prevent cataracts with adequate intake

🛡️ 4. Antioxidant Defense

• Helps regenerate glutathione, one of your body’s most powerful antioxidants

⚠️ Signs of B2 Deficiency

Though rare, deficiency can occur with poor diet or malabsorption. Symptoms include:

• Cracks or sores at the corners of the mouth (angular cheilitis)

• Swollen or sore tongue (magenta tongue)

• Dry skin or dermatitis

• Light sensitivity and red eyes

• Fatigue or weakness

🥚 Where to Get Vitamin B2

✅ Top Food Sources:

Milk and dairy products Rich source

Liver and organ meats Very high

Lean meats Pork, beef, chicken

Almonds Good plant-based option

Fortified cereals Reliable source

Spinach, mushrooms, asparagus Moderate plant sources

💡 Riboflavin is light-sensitive, so keep foods like milk in opaque containers!

  • Reduce migraine frequency

  • Support energy levels during fatigue

  • Assist in eye health

🛑 Can You Get Too Much?

• Unlikely to cause harm—excess is excreted in urine

• High doses may turn urine bright yellow (harmless and common!)

🧠 Final Thoughts

Vitamin B2 is like the wiring technician in your body’s energy plant—ensuring smooth electricity (ATP) production and reducing system breakdown.

To keep your levels up:

• Eat a varied diet with animal and/or fortified plant foods

• Consider B-complex support during stress, illness, or intense exercise
