Vitamin B2 Benefits, Dosage & Side Effects Supplement Information and Usage Guide
Vitamin B2, also known as Riboflavin, supports energy production, maintains healthy skin and eyes, and promotes the breakdown of fats, proteins, and carbohydrates.
Vitamin B2 (Riboflavin) is a water-soluble vitamin involved in energy production and cellular function. It helps convert carbohydrates into fuel and supports antioxidant activity.
Found in dairy, meat, and leafy greens, riboflavin also promotes healthy skin and vision. Deficiency can lead to mouth sores, fatigue, and sensitivity to light.
Vitamin B2 is taken for energy support and migraine prevention. It is generally safe, with excess excreted in urine, often giving it a bright yellow color.

Dosage
The Vitamin B2 supplement dosage is personalized to meet individual health needs and medical advice:
- Energy production and eye health: 1.1–1.3 mg/day for adults; higher for athletes and pregnant women.
- Supplemental form: 10–100 mg/day of Riboflavin (Vitamin B2) commonly used.

Side Effects
Vitamin B2 (Riboflavin) plays a key role in energy production, but some users may experience mild side effects as they adjust. Watch for:
- Bright yellow urine—harmless excess excretion
- Occasional mild gastrointestinal upset—nausea or stomach cramps—if taken without food
- Possible headache or dizziness in sensitive individuals
- Rare skin rash or itching—hypersensitivity reactions
- High doses may lead to increased urine frequency
Interactions
Possible interactions include:
- Vitamin B2 and B6 therapies: B2 supports B6 function; combined use with B6 is generally safe but monitor total intake.
- Antidepressants: May have minor complementarity with Folic Acid in mood support.
Precautions
Before taking Vitamin B2, confirm none of the following apply to you. If they do, consult your healthcare provider:
- Individuals with kidney impairment: May accumulate in renal dysfunction; monitor levels
- People prone to migraines: Riboflavin can sometimes trigger headaches; adjust dose if necessary
- Those on certain medications (e.g., phenobarbital): May increase riboflavin requirements; consult your doctor
- Pregnant or breastfeeding women: Generally safe at recommended levels; avoid excessive doses
- Patients scheduled for surgery: Continue normal intake unless otherwise advised
Studies
These studies provide scientific insights into Vitamin B2 benefits:
A 2004 randomized crossover trial in 51 migraine sufferers found 400 mg/day riboflavin reduced monthly attack frequency by 1.1 episodes versus 0.5 with placebo (P < 0.05).
A 2007 study comparing 200 mg vs 400 mg/day found no additional benefit at lower dose, indicating a threshold effect for migraine prophylaxis.
A recent small trial in healthy adults showed 100 mg/day riboflavin for 4 weeks did not enhance exercise performance or recovery markers versus placebo (ns).
No RCTs have assessed riboflavin for anemia prevention or metabolic health in general populations, limiting support beyond specific neurologic use.
