Product Quality and Formulation

Bio-Tech Pharmacal is a trusted name in supplement manufacturing, and their B2-400 product exemplifies their dedication to purity and potency. Each capsule contains 400 mg of pure riboflavin (vitamin B2) in its standard form, without unnecessary additives, fillers, or common allergens. The product is entirely non-GMO and free from dairy, egg, fish, gluten, peanuts, shellfish, soya, tree nuts, wheat, and artificial colours. This careful formulation ensures that B2-400 is suitable for individuals with multiple food sensitivities or those who prefer a clean, straightforward supplement. Manufactured in facilities adhering to strict quality control standards, B2-400 delivers a reliable dose of riboflavin that has been used in clinical research.

What Is Riboflavin (Vitamin B2)?

Riboflavin, also known as vitamin B2, is an essential water-soluble vitamin that plays a vital role in energy production. It acts as a building block for coenzymes involved in the metabolism of carbohydrates, fats, and proteins, helping your body convert food into usable energy. Adequate riboflavin intake is necessary for normal energy-yielding metabolism and to reduce tiredness and fatigue. While riboflavin is naturally present in foods like dairy products, eggs, lean meats, and green leafy vegetables, some people may not obtain enough from diet alone due to dietary restrictions, lifestyle choices, or increased needs. A supplement such as B2-400 can help bridge that gap, providing a potent and precisely measured 400 mg dose per capsule.

Key Benefits of B2-400

B2-400 supports normal energy-yielding metabolism and contributes to the reduction of tiredness and fatigue. It also contributes to the normal functioning of the nervous system, which can help maintain mental clarity and focus during daily activities. The 400 mg dose is a level that has been investigated in research settings for its potential benefits. Additionally, the supplement is formulated without common allergens and artificial colours, making it a safe choice for those with sensitivities. Its non-GMO status further reflects the brand's commitment to natural ingredients.

Who May Benefit from B2-400?

Individuals looking to support their energy levels and nervous system function may consider B2-400 as part of their daily routine. Those with dietary restrictions or higher riboflavin requirements may find this supplement particularly useful. However, it is always advisable to consult a health care professional before starting any new supplement, especially at a dose of 400 mg per day. B2-400 is especially suitable for people avoiding gluten, dairy, eggs, fish, peanuts, tree nuts, soya, and shellfish, as it is free from these allergens. Always check the label for the most current ingredient information.

How to Uses B2-400

The recommended dose is one capsule per day, or as directed by a health care professional. For best results, take the capsule with a meal and a full glass of water. Consistency is important; taking it at the same time each day can help establish a routine. Store B2-400 in a cool, dry place away from direct sunlight and out of reach of children. Each bottle contains 100 capsules, providing a 100-day supply at the recommended dose.

Safety and Side Effects

High-dose riboflavin (400 mg) is generally considered safe. The Reference Nutrient Intake (RNI) for riboflavin in the UK for adults is approximately 1.1–1.3 mg per day, so this supplement provides a significantly higher amount. However, high doses are well tolerated. Possible side effects are rare and may include mild digestive upset or harmless bright yellow urine (due to excess riboflavin being excreted by the kidneys). Do not exceed the recommended dose unless advised by your health care provider. This product is a food supplement and should not be used as a substitute for a varied diet and healthy lifestyle. If you have any medical conditions or are taking medication, consult your doctor before uses.

Frequently Asked Questions

Does B2-400 contain artificial colours?

No, B2-400 is free from artificial colours.

How long does one bottle last?
