Vitamin B2 (Riboflavin)

Vitamin B2 (riboflavin) is essential for energy production and protecting cells, supporting overall health.

📋 About This Biomarker

Vitamin B2, or riboflavin, is an essential nutrient that plays a crucial role in your body's energy production. Imagine it as a helper that assists in converting the food you eat into the energy you need for daily activities. It supports the breakdown of proteins, fats, and carbohydrates, and also helps maintain healthy skin and eyes. Additionally, Vitamin B2 acts like a protective shield for your cells, guarding them against damage from free radicals. It's a key player in the B-vitamin family, working closely with other B vitamins to keep your body's systems running smoothly. Whether you're at rest or on the move, Vitamin B2 is hard at work behind the scenes, contributing to your overall health and well-being.

🎯 Why We Test This

Testing Vitamin B2 levels helps ensure your body has enough riboflavin to support energy production, protect cells, and maintain healthy skin and eyes. It's especially important if you have dietary restrictions, absorption issues, or increased nutritional needs, such as during pregnancy or breastfeeding. Knowing your levels can guide dietary adjustments or supplementation to prevent deficiency and promote well-being.

⚠️ What Affects It

Several factors can influence Vitamin B2 levels in your body. Your diet is a major factor - if you don't consume enough riboflavin-rich foods like dairy products, eggs, green vegetables, and lean meats, your levels may drop. Conditions that affect absorption, such as celiac disease or other digestive disorders, can also lower your Vitamin B2 levels. Excessive alcohol intake can interfere with how your body absorbs and uses riboflavin. Certain medications, like some antibiotics or birth control pills, might reduce Vitamin B2 levels as well. Pregnancy and breastfeeding increase the body's demand for riboflavin, so levels may vary during these times for women.

📈 How to Improve

If your Vitamin B2 levels are high or close to being high, you may not need to take any action, as excess riboflavin is excreted naturally. However, you might consider reviewing any supplements with a healthcare provider to avoid unnecessary intake. If levels are low or approaching low, increasing your intake of riboflavin-rich foods like dairy products, lean meats, eggs, nuts, and green leafy vegetables can help. In some cases, a supplement may be recommended by a healthcare professional to boost your levels back to normal. Regular monitoring ensures you maintain optimal levels for good health.

📊 Understanding Your Results (nmol/L)

Low (< 6 nmol/L)
Low levels of Vitamin B2 can lead to symptoms like fatigue, sore throat, cracks at the corners of the mouth, and skin disorders. This deficiency means your body isn't getting enough riboflavin to perform essential functions. Causes can include poor diet, absorption problems, or increased requirements. Addressing this typically involves improving dietary intake or taking supplements under medical guidance to restore healthy levels.
Optimal (6 - 40 nmol/L)
Having Vitamin B2 levels within the normal range indicates that you're getting just the right amount of riboflavin. Your body has what it needs to support energy production, protect cells from damage, and keep your skin and eyes healthy. This balance is a positive sign that your diet is meeting your nutritional needs. If your Vitamin B2 levels are near the upper limit, it likely means you're getting ample riboflavin from your diet or supplements. There's generally no cause for concern, as excess amounts are excreted by the body. However, maintaining levels within the optimal range ensures you're not over-supplementing unnecessarily. Levels approaching the lower limit may suggest that your intake of Vitamin B2 isn't quite sufficient. This could be due to dietary habits, absorption issues, or increased needs. It's a gentle reminder to consider including more riboflavin-rich foods in your meals, such as milk, eggs, almonds, and green leafy vegetables.
High (> 40 nmol/L)
Elevated levels of Vitamin B2 are rare because the body doesn't store large amounts of it - the excess is usually flushed out in urine. If levels are unusually high, it might be due to over-supplementation. While no serious side effects are known from high riboflavin intake, it could indicate that you're consuming more than your body needs. It's a good idea to review any supplements you're taking with a healthcare provider to ensure you're not exceeding the recommended amounts.
