What It Measures

This test measures riboflavin (vitamin B2) levels in your blood, expressed in nmol/l. It may help assess whether your body has adequate riboflavin for energy production and antioxidant defence. Your healthcare provider can interpret results within your clinical context.

Why It Matters

For women, riboflavin may support energy levels during hormonal fluctuations and has been studied for potential benefits in migraine prevention. Low levels may be associated with fatigue and skin changes. A healthcare provider can help interpret your results.

When to Test

Testing may be considered when experiencing persistent mouth sores, cracked lips, skin inflammation, or light sensitivity. Healthcare providers may also suggest testing for individuals with restrictive diets, malabsorption conditions, or those taking certain medications.

Symptoms

Low Levels

Some people with low vitamin B2 may experience cracked or sore lips, mouth ulcers, a sore throat, skin rashes, or sensitivity to light. Fatigue and eye irritation have also been reported. A healthcare provider can help determine if B2 deficiency is the cause.

High Levels

Elevated vitamin B2 levels are generally considered uncommon as excess riboflavin is typically excreted in urine. Some people may notice brightly coloured urine with high intake. If your levels appear elevated, your healthcare provider can advise on next steps.

Lifestyle Tips

Foods considered rich in riboflavin include dairy products, eggs, lean meats, green vegetables, and fortified cereals. Some people may benefit from including a variety of these foods daily. Discuss any dietary concerns with your healthcare provider or dietitian.
