Riboflavin is one of the water-soluble B vitamins and is also known as vitamin B2. It is needed for converting food to energy, works as an antioxidant by scavenging damaging free radicals, and is needed to convert vitamin B6 and folate into active forms.
How much riboflavin do I need to consume?
There is insufficient information to establish an RDA for vitamin riboflavin for infants. In this case, an Adequate Intake (AI) has been established:
Age
Males and Females
0 to 6 months
0.3 mg
7 to 12 months
0.4 mg
The Recommended Dietary Allowance (RDA) for riboflavin is:
Age
Males
Females
Pregnancy
Lactation
1 to 3 years
0.5 mg
0.5 mg
N/A
N/A
4 to 8 years
0.6 mg
0.6 mg

9 to 13 years
0.9 mg
0.9 mg

What are sources of riboflavin?
Though riboflavin can be found in most animal and plant foods, it is destroyed
by light, so these foods need to be stored away from light to protect it. It can
be lost in the water if foods are boiled or soaked, so avoid doing this or
consume the water along with the food (for example, soup).
A well-balanced diet can provide enough riboflavin to reach your RDA. When your diet is limited in variety or you have a medical condition that interferes with the absorption of riboflavin, you may need a supplement. The most common forms of riboflavin found in supplements are riboflavin 5-monophosphate and riboflavin. These can be purchased alone, in a multivitamin, or in a B complex supplement.
What happens if I don't have enough riboflavin?
Riboflavin deficiency can occur from not consuming enough in your diet and from conditions that decrease the amount absorbed, including malabsorption syndromes, chronic diarrhea, long-term use of barbiturates, peritoneal dialysis, and alcoholism. Ariboflavinosis is caused by riboflavin deficiency. The symptoms include fatigue, cracks and sores around the corners of the mouth (angular stomatitis/cheilosis), eye fatigue, swollen magenta tongue (glossitis), skin irritation (dermatitis), soreness and swelling of the throat, sensitivity to light, and eye fatigue.
Is there such a thing as too much riboflavin?
No Tolerable Upper Limit (UL) has been set for riboflavin. Possible reactions to very high doses include burning/prickling sensations, itching, numbness, and yellow discoloration of the urine. There is also a possibility that riboflavin's photosensitizing (sensitivity to light) properties can pose health risks.
There are many symptoms involved in the 1st, 2nd and 3rd trimesters of pregnancy. The first early pregnancy symptom is typically a missed period, but others include breast swelling and tenderness, nausea and sometimes vomiting, fatigue and bloating. Second trimester symptoms include backache, weight gain, itching, and possible stretch marks. Third trimester symptoms are additional weight gain, heartburn, hemorrhoids, swelling of the ankles, fingers, and face, breast tenderness, and trouble sleeping.

There are many causes of scalp hair loss. This featured article covers the common ones such as patchy hair loss (alopecia areata, trichotillomania, and tinea capitis), telogen effluvium, and androgenetic alopecia (male-pattern baldness, female-pattern baldness).
Learn about osteoporosis, a condition characterized by the loss of bone density, which leads to an increased risk of bone fracture. Unless one experiences a fracture, a person may have osteoporosis for decades without knowing it. Treatment for osteoporosis may involve medications that stop bone loss and increase bone strength and bone formation, as well as quitting smoking, regular exercise, cutting back on alcohol intake, and eating a calcium- and vitamin D-rich balanced diet.
Osteopenia is a bone condition characterized by bone loss that is not as severe as in osteoporosis. Bone fracture is the typical symptom of osteopenia, though the condition may be present without symptoms. Treatment involves lifestyle modifications (quitting smoking, not drinking in excess) and ensuring an adequate intake of vitamin D and calcium.
Hypercalcemia is a condition in which calcium levels in the blood are elevated. Hypercalcemia is associated with other conditions such as hyperparathyroidism, lung cancer, breast cancer, kidney failure, and elevated levels of vitamin D. Symptoms of hypercalcemia include constipation, nausea, abdominal pain, kidney stones, to name a few. Treatment depends on the cause of hypercalcemia.
Pregnancy planning is important to help prevent exposure of the mother and fetus to potentially harmful medications and substances during the early days, and throughout the pregnancy. Nutritional planning, prevention of birth defects, conditions such as high blood pressure, heart disease, diabetes, and kidney disease need careful monitoring. Gestational diabetes, preeclampsia, and pregnancy induced hypertension are conditions that may arise during pregnancy. Immunizations, inherited disorders, exercise, air travel, intercourse, and birth control are important factors to consider when planning a pregnancy.
Rickets is caused by a deficiency of vitamin D, calcium or phosphate. Infants and children who are exclusively breastfed, have dark skin, and infants born to mothers who are vitamin D deficient are most at risk for developing rickets. Symptoms and signs of rickets include bone pain, delayed teeth formation, short stature, skeletal deformities (bowlegs, abnormally shaped skull), and decreased muscle strength. Treatment of rickets depends upon the cause, but the first step usually involves correcting any abnormal levels of calcium, phosphate, or vitamin D with supplements.
Vitamin D deficiency has been linked with rickets, cancer, cardiovascular disease, severe asthma in children and cognitive impairment in older adults. Causes include not ingesting enough of the vitamin over time, having limited exposure to sunlight, having dark skin, and obesity. Symptoms include bone pain and muscle weakness. Treatment for vitamin D deficiency involves obtaining more vitamin D through supplements, diet, or exposure to sunlight.
Enjoying a healthy diet helps to prevent diseases. A good diet also helps to control celiac disease, diabetes, and high blood pressure and maintain health by preventing loss of bone mass, muscle strength, and vitamin deficiencies.
Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.
The importance of a healthy lifestyle in disease prevention is widely understood and most people know that lifestyle changes and choices can be critical to good health. Yet, few practice healthy behaviors that constitute healthy living.
Disease prevention in men includes routine screening tests that are part of basic prevention medicine. Take an active role in your own health care and discuss screening tests with your doctor early in life. Age of screening and timing of screening depends upon the condition being assessed.
Disease prevention in women includes screening tests that are a basic part of prevention medicine. All screening tests
are commonly available through your general doctor. Some specialized tests may be available elsewhere.
Setting a good example for your children when it comes to diet and exercise will help them to make healthy decisions about nutrition and fitness. Eating calcium-rich foods and performing weight-bearing exercise will help your children prevent osteoporosis and fractures later in life.
