Riboflavin is another name for Vitamin B2, one of a group of nutrients required by the body which acts as an important antioxidant within the body. It has a number of important roles within the human body and minimum levels are required in order to keep blood cells healthy and functioning well, that your metabolism works effectively, and to help you keep and sustain good energy levels. Riboflavin has other key health benefits, including actions which prevent cell damage during the breakdown of products in the body, supporting normal growth processes and functions of the skin and eyes.
The human body does not require huge amounts of this vitamin and as it is water-soluble it can often be found in many common foods which you eat every day. However, for those that suffer from the consequences of a Vitamin B deficiency then Riboflavin is available as a supplement to be taken orally. In particular, Riboflavin is important to ensure the body is able to break down nutrients in your food, such as proteins, fats, and carbohydrates and to help your cells generate the oxygen your system needs to operate.
There are a number of other B vitamins, all of which have a role in digestion and energy production – in particular, providing the base unit of energy in the body, known as ATP. This is the building block for every action you take. The vitamin also acts as an enabler for a number of other nutrients in the same family, such as Vitamin B6 and folic acid, to fulfill their necessary functions. Broadly, this range of vitamins is responsible for vital functions such as nerve health, the health of the heart and blood, actions to reduce inflammation, the ability of hormones to operate, and keeping a healthy metabolism and digestive system.
This means that if you have a Riboflavin deficiency there are a number of serious side effects which will quickly become obvious. These can include the following signs and symptoms:
If you feel you have a deficiency in this important vitamin then you can purchase a supply of oral supplements without a prescription however it may be useful to check with your healthcare professional to ensure you are treating the correct condition. There are, however, a number of medical situations where you may have an increased need for riboflavin. These include:
As a non-prescription drug, available over the counter, Riboflavin is generally considered to be safe for most people to take when required. The most commonly reported side effect is that this supplement may change the color of the person’s urine, usually to a yellow-orange color. It is also reported that excess and high doses of this vitamin can cause diarrhea or other unpleasant side effects such as an increase in passing urine. Persons with hepatitis, cirrhosis or other kinds of biliary obstruction will find their ability to absorb Riboflavin is significantly decreased.
The effective dosage of Riboflavin will depend on the age of the person that needs to take the supplement and the form that you plan to take them in. Capsules are available in either
50mg or 400mg doses, while tablets can usually be purchased in doses of 25mg, 50mg or 100mg. It is useful to consult a health professional to discover the most suitable therapeutic dose for your symptoms or concerns.
There are existing recommendations for a healthy person’s daily allowance (RDA) of Riboflavin in order to maintain healthy bodily function. Scientific research suggests that in men this is around 1.3 mg/day, while women need at least 1.1 mg/day. Pregnant women need slightly more at 1.4 mg/day and women currently breastfeeding are suggested to have a minimum intake of 1.6 mg/day. Where it is deemed necessary for adults to supplement their Riboflavin intake then the suggested level is 6-30 mg/day in divided doses, taken orally.
For children, the doses required are slightly lower but the provision of medication remains fairly similar. Paediatric capsules are available in 50mg or 400mg and tablets are provided in
25mg, 50mg or 100mg. The recommended intake for this group is 0.3 mg/day for infants aged up to six months, 0.4 mg/day for five to twelve month old infants, 0.5 mg/day at one to three years, 0.6 mg/day at three to eight years, 0.9 mg/day for eight to thirteen years. Finally, young adults of thirteen to eighteen years require 1.3 mg/day (for young men) and 1 mg/day (for young women).
If you are on an existing drug regime then you may find that some of your existing medications could clash with a Vitamin B supplement.

As with all supplements and medications, these products should be kept away from children in a tightly sealed container. It is also important that you check the expiry date on the package before taking doses of this supplement.
Riboflavin plays a number of important roles within the human body, including energy generation, growth, absorption of foods and the general health of a variety of bodily symptoms. Persons with a deficit of this micronutrient can suffer from a range of symptoms, such as anemia, changes in the metabolism, nerve damage and inflammation. This can be treated with regular doses of oral riboflavin, both in adults and in children, and this treatment is generally considered to be safe (providing the appropriate doses are taken.)
