NOW Supplements, Vitamin B-2 (Riboflavin) 100 mg, Energy Production*, 100 Veg Capsules

Benefits of Riboflavin

Riboflavin contributes to normal energy-yielding metabolism, supporting daily vitality. It also helps maintain normal red blood cells and normal function of the nervous system, while aiding in the protection of cells from oxidative stress.* For those on plant-based diets or with limited dairy intake, supplementation can be particularly helpful. Each capsule provides 100 mg of riboflavin—a potent dose to support these essential functions.

What Is Riboflavin (Vitamin B2)?

Riboflavin, also known as vitamin B2, is a water-soluble vitamin crucial for energy production and cellular health. It is a key component of two major coenzymes—flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD)—which are essential for metabolizing carbohydrates, fats, and proteins. These coenzymes participate in the electron transport chain, converting food into usable energy. Riboflavin also supports regeneration of glutathione, a vital antioxidant that protects cells from oxidative stress. Found naturally in dairy, eggs, and green vegetables, riboflavin supplementation can fill dietary gaps, especially for those with increased needs or limited intake.

How to Choose the Right Riboflavin Supplement

When selecting a riboflavin supplement, consider the form and dosage. This product delivers 100 mg per capsule of well-absorbed riboflavin. Look for third-party testing and quality certifications: this supplement is Non-GMO, Soy Free, Made without Gluten, Dairy Free, and Egg Free. It is also GMP Quality Assured, meaning each manufacturing step is evaluated for stability, potency, and formulation. For a clean label, it contains No artificial additives and is suitable for vegans (vegetable capsules).

Who Should Consider a Riboflavin Supplement?

Individuals with limited dietary intake of B vitamins—such as vegans, vegetarians, or those avoiding dairy—may benefit from riboflavin supplementation. Athletes and active individuals may also find it helpful for energy metabolism. Older adults and those with digestive conditions that impair nutrient absorption might consider a supplement. As always, consult a healthcare professional to determine if riboflavin is appropriate for your needs.

Recommended Dosage and Safety

The typical dosage for riboflavin supplements ranges from 100 mg to 400 mg per day. This product contains 100 mg per capsule; take one capsule daily with a meal. Riboflavin is water-soluble, so excess is excreted in urine, which may turn a bright yellow colour—a harmless effect. The upper tolerable intake level has not been established, but high doses (above 400 mg daily) are not recommended without professional guidance. Side effects are rare but may include mild gastrointestinal upset. Consult your healthcare provider before starting any new supplement regimen.
