Description
Vitamin B2, also known as riboflavin, is a water-soluble vitamin that is necessary for normal growth and maintenance of health as it functions as a coenzyme in energy metabolism. Riboflavin is also necessary for red blood cell formation, antibody production, cell respiration and growth, and works as an antioxidant to track down and destroy free radicals in the body.
Riboflavin functions in the metabolism of proteins, fats, and carbohydrates, enabling the body to release energy from these nutrients and making them available to tissue cells. It also supports healthy vision and helps maintain healthy skin.
As riboflavin is not stored in the body, it must be added in the diet daily either through food sources or through supplementation. Unfortunately, vitamin B2 is not available in a wide variety of foods nor is it present in large quantities in foods, so a deficiency is common in those who have unbalanced diets. Natural Factors Vitamin B2 contains 100 mg of riboflavin per tablet to help in the maintenance of good health and especially in the metabolism of proteins, fats, and carbohydrates.
Frequently Asked Questions
What is Natural Factors Vitamin B2 Riboflavin 100mg and what is it used for?
Natural Factors Vitamin B2 Riboflavin 100mg is a high-potency B vitamin supplement providing 100mg riboflavin per tablet. Riboflavin (Vitamin B2) is a water-soluble B vitamin essential for energy metabolism — it plays a central role in the electron transport chain and the production of ATP from carbohydrates, fats, and proteins. It also supports glutathione recycling (an antioxidant), red blood cell production, and healthy skin and mucous membranes. High-dose riboflavin has been studied for migraine prevention.
How does riboflavin work and what does it do in the body?
Riboflavin functions as the precursor to two essential coenzymes: FMN (flavin mononucleotide) and FAD (flavin adenine dinucleotide). These coenzymes are required at multiple steps in the Krebs cycle and electron transport chain for cellular energy production. FAD is also needed to recycle glutathione, the body's primary antioxidant. Riboflavin supports red blood cell formation and maintains healthy mucous membranes. Because it is water-soluble, excess riboflavin is excreted in urine, which typically turns bright yellow — a normal and harmless effect.
Who should take Natural Factors Riboflavin 100mg and how is it used?
Suitable for adults with increased riboflavin needs, including those who follow a vegan or vegetarian diet (animal products are the richest dietary sources), individuals with high energy demands, or those with riboflavin-dependent enzyme deficiencies. Adults who have discussed high-dose riboflavin with their physician for migraine prevention may also use this supplement. Take 1 tablet per day. Bright yellow urine is expected and harmless. Not intended to replace prescribed migraine treatments without medical guidance.
What makes Natural Factors Riboflavin 100mg stand out compared to other B2 supplements?
At 100mg per tablet, this product provides a therapeutically relevant dose: clinical trials on riboflavin for migraine prevention have used 400mg per day, which corresponds to 4 tablets of this product. Many standard B-complex formulas contain only 1 to 10mg of riboflavin — far below studied migraine-prevention doses. The single-ingredient format lets users adjust dose precisely in consultation with their healthcare provider. Natural Factors manufactures in their own cGMP-certified BC facility. At $8.99 for 90 tablets, this product offers a cost-effective entry point for high-dose B2 supplementation.
What is Natural Factors, and is it a trustworthy supplement brand?
Natural Factors is a Canadian-owned supplement manufacturer founded in 1948 and headquartered in Coquitlam, British Columbia. One of North America's largest supplement makers, it operates over 1,000 acres of certified organic farmland in BC's Okanagan Valley and manufactures in-house at Health Canada-licensed, FDA-inspected facilities. Every product is third-party tested through ISURA for over 800 contaminants including pesticides and heavy metals. Natural Factors is also B Corp certified, meeting rigorous environmental and social standards.
What is Natural Factors and is it a reliable Canadian supplement brand?
Natural Factors is one of Canada's largest supplement manufacturers, founded in 1955 by Jack and Rona Katz in British Columbia and still 100% Canadian family-owned. The company controls every production stage from raw material sourcing to finished product. Its facility holds TGA certification from Australia's Therapeutic Goods Administration, one of the world's strictest supplement manufacturing standards. All products are ISURA certified — independently tested for 800+ contaminants including pesticides and heavy metals — and Natural Factors conducts four rounds of product testing, double the industry average of two.
What sets Natural Factors apart from other supplement brands?
Natural Factors' most distinctive quality is vertical integration: the company grows its own raw herbs on 1,000+ acres of certified organic farmland in BC's Okanagan Valley, then processes and manufactures in-house. Most supplement brands source raw materials from external suppliers with no direct agricultural control. Natural Factors also uses ISURA third-party testing, a Canadian standard that screens for over 800 contaminants, well beyond typical heavy-metal panels. B Corp certification further reflects a documented commitment to environmental and social accountability, not just a marketing claim.
What makes Natural Factors different from other Canadian supplement manufacturers?
Natural Factors holds TGA certification from Australia's Therapeutic Goods Administration — one of the world's most rigorous pharmaceutical manufacturing standards, rarely earned by Canadian brands and far exceeding most North American certification requirements. Its ISURA testing program screens every product for 800+ contaminants, and it conducts four rounds of quality testing per product versus the industry standard of two. The company also operates its own farm in the Okanagan Valley for select botanical ingredients — a level of vertical integration uncommon among supplement manufacturers — and has been family-owned for over 70 years.
