Riboflavin (vitamin B2) is a yellow-colored nutrient involved in dozens of metabolic pathways leading to energy production and the making of fatty acids and sterols. Good sources are lean meats, eggs, milk, some vegetables and enriched cereals. The recommended daily intake of riboflavin iis about 1.5 mg. You may notice your urine turning a deeper yellow color after taking riboflavin.

Riboflavin is part of two larger activated coenzymes known as flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). FMN is now available as a supplement. One product contains 25 mg of FMN per pill. Human studies giving FAD or FMN in order to evaluate cognitive functioning have not yet been published.

Migraine headache
Int J Vitam Nutr Res. 2015. Supplementation with Riboflavin (Vitamin B2) for Migraine Prophylaxis in Adults and Children: A Review. Migraine is a unilateral and pulsating headache associated with nausea, photophobia, vomiting, and sensitivity to light. Low vitamin B2 can lead to mitochondrial dysfunction and may have an effect on migraine pathogenesis. The aim of the present study was to carry out a review of existing evidence regarding the effects of riboflavin (vitamin B2) supplementation on migraine prophylaxis in adults and children. It seems that riboflavin is a safe and well-tolerated option for preventing migraine symptoms in adults, however, there is insufficient evidence to make recommendations regarding vitamin B2 as an adjunct therapy in adults and children with migraine.

Riboflavin is an essential B vitamin typically found in meat, eggs, dairy and legumes. Riboflavin is utilized by the liver, brain, heart and other tissues to synthesize flavine mononucleotide (FMN) and flavine adenine dinucleotide (FAD), the active forms of riboflavin. FMN and FAD are cofactors for a variety of oxidative enzyme systems and function as electron carriers important for the synthesis of energy (ATP). FAD is also involved in the activation of folate, the metabolism of neutrotransmitters, and regeneration of reduced glutathione. Alcohol reduces digestion and absorption of riboflavin. Riboflavin also supports the metabolism of carbohydrates.

Suggested Use: Take 1 riboflavin capsule per day with a meal, or as directed by your qualified health consultant.

Vopr Pitan. 2013. Vitamin and mineral status of oarsmen during the training-competition cycles. Vitamin and minerals status of 30 sportsmen aged 16.8 +/- 0.2 years (trained in boat racing 5.0 +/- 0.3 years) during the training--competition cycles in autumn and winter has been studied. A significant decrease of vitamin A level in the range of reference limits was found in 30% of sportsmen during autumn season, but such decrease was revealed in 100% of examined sportsmen during winter Vitamin B1 and B2 deficiency has been detected in both seasons. The portion of persons with vitamin B2 deficiency increased during training cycles. A significant decrease of magnesium (in 56.3% of sportsmen) and sodium level (in 33% of sportsmen) was detected during autumn season. Irrespective of the season a significant decrease of blood serum of calcium (in 40.0-66% of sportsmen); potassium (in 53-66% of sportsmen according to both absolute and individual data); chlorides (in 50-90% of sportsmen), and iron (in 53.3-60.0% of sportsmen) has been revealed. The data obtained indicate the need for diagnostics and correction of vitamin and minerals status in sportsmen.
