Swanson Vitamin B2 (Riboflavin) 100 mg - 100 Capsules

Benefits of Riboflavin

Riboflavin (vitamin B2) contributes to several normal bodily functions. It aids normal energy-yielding metabolism, helping your body efficiently convert food into fuel. It also helps maintain normal vision and supports normal functioning of the nervous system. Furthermore, riboflavin contributes to the protection of cells from oxidative stress and supports normal red blood cell formation. For thyroid health, it plays a role in converting thyroxine (T4) to its active form triiodothyronine (T3), thereby contributing to normal thyroid function.

What Is Riboflavin (Vitamin B2)?

Riboflavin, also known as vitamin B2, is an essential water-soluble vitamin crucial for energy production. It forms part of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are involved in cellular metabolism. These coenzymes help convert carbohydrates, fats, and proteins into usable energy, making riboflavin vital for overall vitality. Swanson's Vitamin B2 supplement delivers 100 mg of pure riboflavin per capsule in a convenient, easy-to-swallow form.

How to Choose the Right Riboflavin Supplement

When selecting a vitamin B2 supplement, consider the form and dosage. This product contains riboflavin (also known as riboflavin 5′-phosphate), the active coenzyme form that is readily utilised by the body. Each capsule provides 100 mg, a dosage commonly used and well within safe limits. Look for independent testing to ensure purity and potency. Swanson's supplement is manufactured in GMP-certified facilities and undergoes independent laboratory testing, guaranteeing quality. The capsules are non-GM and free from unnecessary additives, making them a clean choice for everyday support.

Who Should Consider a Riboflavin Supplement?

Although riboflavin is present in foods such as dairy products, eggs, lean meats, and green vegetables, certain individuals may benefit from supplementation. Those with dietary restrictions (e.g., vegans or lactose intolerant individuals), older adults, and people with conditions affecting absorption (such as inflammatory bowel disease) may have higher requirements. Athletes and those with high physical demands may also find supplementary riboflavin helpful to support energy metabolism. Swanson's riboflavin is an excellent choice for anyone looking to conveniently fill nutritional gaps.

Recommended Dosage and Safety

The UK reference nutrient intake (RNI) for riboflavin is approximately 1.1–1.3 mg per day for adults, but higher dosages (such as 100 mg) are often used for specific health goals and are considered safe. No upper limit has been established due to its low toxicity; typically, supplementary doses range from 100 to 400 mg per day. For best results, take one capsule daily with food and water. Riboflavin is water-soluble, so excess is excreted in urine, which may cause a harmless yellowish discolouration. Consult your health care provider before starting any new supplement regimen.
