NuSci Vitamin B2 Riboflavin Pure Powder, 227g

Benefits of Riboflavin for Energy and Vitality

Riboflavin (vitamin B2) contributes to normal energy-yielding metabolism, helping your body convert food into usable fuel. It also supports normal red blood cell formation, healthy vision, skin, and mucous membranes, and helps protect cells from oxidative stress. Many people choose riboflavin as part of a B-complex or on its own for targeted support. The powder form allows flexible dosage to meet individual needs.

What Is Riboflavin (Vitamin B2)?

Riboflavin is a water-soluble vitamin essential for energy production. It acts as a coenzyme in the electron transport chain, supporting mitochondrial function and cellular metabolism. This pure powder from NuSci contains no additives, fillers, or preservatives — just the active vitamin in its free form. It appears as a bright yellow crystalline powder with a characteristic bitter taste and is slightly soluble in water. Because it is unadulterated, it is an excellent choice for customising your dosage or incorporating into homemade formulations.

Recommended Dosage and Safety

The typical supplementary dose of riboflavin ranges from 100 mg to 400 mg per day. As a pure powder, you can easily measure your desired amount using a milligram scale. The tolerable upper intake level is 400 mg per day; however, riboflavin is generally considered safe even at higher doses because excess is excreted in urine, often giving it a bright yellow colour — a harmless effect. Possible side effects are rare but may include gastrointestinal discomfort. Always consult a health care professional before starting a new regimen, especially if you are pregnant, nursing, or taking medication. Do not uses this product to diagnose, treat, , or prevent any disease.

How to Choose the Right Riboflavin Supplement

Riboflavin is available in several forms: riboflavin (the free form) and riboflavin 5'-phosphate (the active coenzyme form). This product contains riboflavin, the most common and cost-effective form, which is efficiently converted to its active form in the body. For most people, standard riboflavin provides excellent bioavailability. When selecting a supplement, consider purity, dosage, and third-party testing. NuSci’s riboflavin powder is pure, with no excipients or flow agents, making it suitable for those with sensitivities or strict dietary preferences. The 227-gram bulk size offers excellent value for long-term uses. Always store the powder in a cool, dry place away from strong light and heat to maintain potency.

Frequently Asked Questions

How do I take riboflavin powder?

Measure the desired dose (e.g., 100 mg) and mix it with water, juice, or a smoothie. The powder has a bitter taste, so blending with flavourful liquids can help mask it. It can also be added to capsules if you prefer.

Why is my urine bright yellow after taking riboflavin?

This is normal. Riboflavin is a fluorescent compound, and any excess not needed by the body is excreted in urine, causing a bright yellow colour. It is harmless and indicates that you are getting enough.

How should I store this riboflavin powder?

Store in a cool, dry place away from direct sunlight and heat. Keep the container tightly sealed to prevent moisture absorption. Under proper conditions, the shelf life is 1.5 to 2.5 years.
