Nutricost R-5-P (Riboflavin-5-Phosphate) (Vitamin B2) 50 mg, 120 Vegan Capsules

Benefits of Riboflavin

Riboflavin (vitamin B2) is essential for converting food into usable energy. It contributes to normal energy-yielding metabolism, helping you stay active throughout the day. This nutrient also supports the formation of normal red blood cells, which are vital for oxygen transport. Additionally, riboflavin helps protect your cells from oxidative stress by regenerating glutathione, a key antioxidant. EFSA-approved health claims confirm that riboflavin contributes to the maintenance of normal neurological function and healthy skin. With Nutricost R-5-P, you get the active coenzyme form for optimum support of these vital processes.

Who Should Consider a Riboflavin Supplement?

While a balanced diet provides riboflavin from sources like dairy, eggs, and leafy greens, certain individuals may benefit from supplementation. Vegetarians, vegans, and those with limited dairy or egg intake may have lower levels. Athletes or people with high physical demands often require extra support for energy metabolism. Individuals with digestive conditions such as coeliac (already correct, but needed to verify) disease or inflammatory bowel disease may also need supplementation due to impaired absorption. Pregnant and breastfeeding women have increased riboflavin needs as well. Always consult a health care professional before starting any new supplement regimen, especially if you have underlying health concerns.

How to Choose the Right Riboflavin Supplement

Not all riboflavin supplements are the same. Many contain standard riboflavin, which requires conversion in the body. Nutricost R-5-P provides riboflavin-5-phosphate (R-5-P), the active coenzyme form that is more readily utilised. With 50 mg per capsule—well above the Reference Nutrient Intake of 1.1–1.3 mg—this high-potency option offers targeted support. The capsules are vegan and non-GMO, and the product undergoes rigorous third-party testing for purity and potency. Manufactured in an NSF Certified, GMP Compliant facility, it meets stringent quality standards you can trust.

What Is Riboflavin (Vitamin B2)?

Riboflavin is a water-soluble vitamin that acts as a precursor to flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), coenzymes essential for energy production. Almost every cell in your body relies on riboflavin to break down carbohydrates, fats, and proteins for fuel. It also functions as an antioxidant, helping to neutralise free radicals that can cause oxidative stress. While foods like dairy, eggs, and fortified cereals provide riboflavin, cooking and light exposure can degrade it. That’s why many people turn to a reliable supplement like Nutricost R-5-P to meet their daily needs.

Recommended Dosage and Safety

For adults, typical riboflavin supplementation ranges from 25 to 200 mg per day, with 50 mg being a common starting point. No tolerable upper intake level has been established due to its low toxicity; excess is simply excreted in urine. However, doses above 400 mg are sometimes used under medical supervision for specific conditions. Side effects are rare but may include bright yellow urine (harmless) or mild digestive upset. As with any supplement, consult your health care provider before undertake, especially if you are pregnant, nursing, or taking medications. Always read the labelled and follow directions for undertake.

Is riboflavin-5-phosphate better than regular riboflavin?

Riboflavin-5-phosphate (R-5-P) is the active coenzyme form, meaning it bypasses the conversion step required with standard riboflavin. This may offer improved absorption and utilisation, particularly for individuals with certain genetic variations or digestive issues.
