This dosage is significantly above the Recommended Daily Allowance, making it suitable for addressing potential deficiencies or providing general support for metabolic functions. The product's primary strength lies in its exceptional value, offering a high number of servings at a very low price per dose.

Online reviews indicate general satisfaction, though its popularity is not as widespread as some other brands.

bolt Effectiveness for goals
Riboflavin is essential for cellular energy production, the metabolism of fats, and the conversion of other B vitamins into their active forms. It plays a crucial role in maintaining healthy skin, eyes, and nerve function by supporting various metabolic processes.
Some research suggests that high-dose Riboflavin supplementation may help reduce the frequency and duration of migraine attacks in certain individuals. This effect is thought to be due to its role in improving mitochondrial energy metabolism.
Riboflavin is vital for the body's energy production processes by helping convert food into usable energy. While essential for preventing fatigue due to deficiency, supplemental Riboflavin typically does not provide an 'energy boost' in individuals who are not deficient.
Riboflavin is important for normal vision and is being studied for its potential role in preventing or slowing the progression of certain eye conditions, such as cataracts. Its involvement in antioxidant pathways may help protect eye tissues from oxidative damage.
Riboflavin supplementation is highly effective in preventing and treating Riboflavin deficiency, also known as ariboflavinosis. Deficiency can lead to symptoms like sore throat, cracks at the corners of the mouth, and certain skin and eye conditions.
schedule Dosage, timing & forms
The Recommended Dietary Allowance (RDA) for adult men is 1.3 mg per day and for adult women is 1.1 mg per day. Higher doses might be used in supplements, often ranging from 5 mg to 100 mg, depending on individual needs or specific conditions. It's best to consult a healthcare professional for personalized dosage advice.
There is no established tolerable upper intake level (UL) for Riboflavin because there is no evidence of toxicity from high intakes. Even at very high doses, excess Riboflavin is typically excreted in the urine. However, extremely high doses can sometimes lead to temporary digestive upset.
For specific conditions, such as migraine prevention, higher doses of Riboflavin are often used, typically around 400 mg per day. This specific dosage should only be taken under the guidance and supervision of a healthcare professional. These doses are significantly higher than the RDA.
Taking Riboflavin with food can enhance its absorption, particularly if the food contains protein. It is fat-soluble in some forms and its absorption is improved in the presence of food. Many recommend taking it with a meal.
Riboflavin is commonly available in supplement form as riboflavin or riboflavin 5'-phosphate (FMN). It can be found in capsules, tablets, and sometimes in liquid formulations. Riboflavin 5'-phosphate is the metabolically active form and is sometimes preferred for better absorption.
health_and_safety Safety & interactions
Riboflavin is generally considered safe for most healthy adults when taken at recommended doses. As a water-soluble vitamin, excess amounts are typically excreted in the urine. Serious adverse effects are rare.
Adequate Riboflavin intake is crucial during pregnancy and lactation for both maternal and infant health. While generally considered safe at recommended doses, pregnant or breastfeeding individuals should consult their healthcare provider before taking any new supplements. Excessively high doses are not recommended without medical supervision.
Riboflavin is generally well-tolerated, even at high doses. The most common noticeable effect is a harmless, bright yellow-orange discoloration of urine. Gastrointestinal upset is rare but possible with very high intakes.
Riboflavin (Vitamin B2) is generally considered safe when consumed in amounts found naturally in foods or from supplements at recommended doses. It is a water-soluble vitamin, meaning excess amounts are typically excreted by the body. Serious adverse effects are rare.
