Riboflavin

Question: How long does riboflavin stay in your system? I'm about to get shipped off to boot camp and I need to redo my urine test since its been a year since i signed. I'm now worried because I've heard riboflavin can mess with your test results and I take "GNC multivitamin for men SPORT" which contains around 2000% of the daily recommended dose of riboflavin. I've only taken it once in the past two weeks but the week before that I took it for 5 days straight. =[

Answer: Riboflavin is a type of B vitamin. It is water soluble, which means it is not stored in the body. You must replenish the vitamin every day. -this is all I could find online- I dunno ifthat helps-

Question: Where do riboflavin, niacin, and thiamine come from? I am very unsure. How do i know where they got it (animals, plants, wheverver) In breads i see these ingredients, but are they from the animal/dairy/egg scources?

Answer: They tell vegetarians to get a dietary B vitamin complex (multiple B vitamins) supplement so it must naturally occur in protein foods like meats and eggs and milk products bread has it too because bread is made with yeast and its added to lots of foods, the supplement pills are made with yeast. Coffee is also very high in niacin! Its added to so many foods that wouldn't normally contain B vitamins. In bread its probably there because of the yeast, yeast is what they make vitamin supplements out of.

Question: I have to make a dish for nutrition class based on Riboflavin(vitamin b2) Any suggestions?

Answer: Asparagus, broccoli and cheese is high in B2. Steam either vegetable and pour melted cheese over it. This site can give a lot of information about B2 deficiency and foods high in it. http://www.naturalhealthtechniques.com/Diet_Nutrition/Vitamin_B2Riboflavin.htm

Question: What diseases can be caused by a riboflavin deficiency? ? And if you happen to know what is the chemical name of riboflavin.

Answer: Riboflavine deficiency primarily causes cheilosis, angular stomatitis, dermatitis, glossitis, conjunctivitis, and a peripheral neuropathy. The combination of the above is termed Ariboflavinosis Riboflavine deficiency can also cause a suppression of the bone marrow resulting in a medullary erythoid hypoplasia Please see site 3 regarding this. Please see the following sites I am a medical doctor.

Question: Is CR-3 crossling with riboflavin to treat keratoconus offered on the NHS? is this procedure offered on the NHS?

Answer: Depends on your age and whether or not you have had any form of corrective surgery performed (I think this only applies to laser and RK). Best to contact Mr Chad Rostron who is leading research into this. His website is www.chad-rostron.co.uk . If you are unable to gain access through this method, the leaders in the field of performing this treatment are Accuvision.

Question: Is Vitamin B2 the same thing as Riboflavin? Looked in the vitamin department in the pharmacy and couldn't find riboflavin. When I did a search online, B2 came up. Is B2 the exact same thing as riboflavin?

Answer: Yes..they are the same. Its best to take B vitamins as vitamin B complex rather than individually. And a time release formulation is the best way to take them as they are excreted rapidly otherwise. You will get more benefit from a time release formula. Hope that helps.

Question: What exactly is riboflavin and what does it do?

Answer: Riboflavin (E101), also known as vitamin B2, is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. It is the central component of the cofactors FAD and FMN, and is therefore required by all flavoproteins. As such, vitamin B2 is required for a wide variety of cellular processes. Like the other B vitamins, it plays a key role in energy metabolism, and is required for the metabolism of fats, ketone bodies, carbohydrates, and proteins. Milk, cheese, leafy green vegetables, liver, kidneys, legumes such as mature soybeans yeast, almonds and rock lobsters[citation needed] are good sources of vitamin B2, but exposure to light destroys riboflavin Riboflavin is not toxic when taken orally, as its low solubility keeps it from being absorbed in dangerous amounts from the gut . Although toxic doses can be administered by injection any excess at nutritionally relevant doses is excreted in the urine, imparting a bright yellow color when in large quantities.[edit] Riboflavin in food Riboflavin powder. A riboflavin solution.Riboflavin is yellow or yellow-orange in color and in addition to being used as a food coloring it is also used to fortify some foods. It is used in baby foods, breakfast cereals, pastas, sauces, processed cheese, fruit drinks, vitamin-enriched milk products, some energy drinks, and is widely used in vitamin supplements. Large quantities of riboflavin are often included in multi-vitamins; often, the dose is far more than a normal human can use in a day. The excess is excreted in the urine, causing the urine to be colored bright yellow within a few hours of ingestion of the vitamin. It is difficult to incorporate riboflavin into many liquid products because it has poor solubility in water. Hence the requirement for riboflavin-5'-phosphate (E101a), a more expensive but more soluble form of riboflavin Nutrition [edit] Riboflavin deficiency Further information: Ariboflavinosis Riboflavin is continuously excreted in the urine of healthy individuals[1], making deficiency relatively common when dietary intake is insufficient. However, riboflavin deficiency is always accompanied by deficiency of other vitamins[1]. A deficiency of riboflavin can be primary - poor vitamin sources in one's daily diet - or secondary, which may be a result of conditions that affect absorption in the intestine, the body not being able to use the vitamin, or an increase in the excretion of the vitamin from the body. In humans, signs and symptoms of riboflavin deficiency (ariboflavinosis) include cracked and red lips, inflammation of the lining of mouth and tongue, mouth ulcers, cracks at the corners of the mouth (angular cheilitis), and a sore throat. A deficiency may also cause dry and scaling skin, fluid in the mucous membranes, and iron-deficiency anemia. The eyes may also become bloodshot, itchy, watery and sensitive to bright light. Riboflavin deficiency is classically associated with the oral-ocular-genital syndrome. Angular cheilitis, photophobia, and scrotal dermatitis are the classic remembered signs. In animals, riboflavin deficiency results in lack of growth, failure to thrive, and eventual death. Experimental riboflavin deficiency in dogs results in growth failure, weakness, ataxia, and inability to stand. The animals collapse, become comatose, and die. During the deficiency state, dermatitis develops together with hair-loss. Other signs include corneal opacity, lenticular cataracts, hemorrhagic adrenals, fatty degeneration of the kidney and liver, and inflammation of the mucus membrane of the gastrointestinal tract. Post-mortem studies in rhesus monkeys fed a riboflavin-deficient diet revealed that about one-third the normal amount of riboflavin was present in the liver, which is the main storage organ for riboflavin in mammals. These overt clinical signs of riboflavin deficiency are rarely seen among inhabitants of the developed countries. However, about 28 million Americans exhibit a common ‘sub-clinical’ stage[citation needed], characterized by a change in biochemical indices (e.g. reduced plasma erythrocyte glutathione reductase levels). Although the effects of long-term sub-clinical riboflavin deficiency are unknown, in children this deficiency results in reduced growth. Subclinical riboflavin deficiency has also been observed in women taking oral contraceptives, in the elderly, in people with eating disorders, and in disease states such as HIV, inflammatory bowel disease, diabetes and chronic heart disease. The fact that riboflavin deficiency does not immediately lead to gross clinical manifestations indicates that the systemic levels of this essential vitamin are tightly regulated.

Question: What are the functions of niacin and riboflavin in the body?

Answer: Niacin is vitamin B-3, one of the water soluble B-complex vitamins. One of niacin's unique properties is its ability to help you naturally relax and get to sleep more rapidly at night. And it is well established that niacin helps reduce harmful cholesterol levels in the bloodstream. Abram Hoffer, M.D., Ph.D. explains: "Niacin is one of the best substances for elevating high density lipoprotein cholesterol (the "good cholesterol) and so decreases the ratio of the total cholesterol over high density cholesterol." Another niacin feature is its ability to greatly reduce anxiety and depression. Yet another feature of niacin is that it dilates blood vessels and creates a sensation of warmth, called a "niacin flush." This is often accompanied with a blushing of the skin. It is this "flush" or sensation of heat that indicates a temporary saturation of niacin, and that is our topic here. Vitamin B2 - riboflavin - information page Riboflavin (vitamin B2) is manufactured in the body by the intestinal flora and is easily absorbed, although very small quantities are stored, so there is a constant need for this vitamin. vitamin,B2,riboflavin Vitamin B2 - riboflavin - is required for It is required by the body to use oxygen and the metabolism of amino acids, fatty acids, and carbohydrates. Riboflavin is further needed to activate vitamin B6 (pyridoxine), helps to create niacin and assists the adrenal gland. It may be used for red blood cell formation, antibody production, cell respiration, and growth. It eases watery eye fatigue and may be helpful in the prevention and treatment of cataracts. Vitamin B2 is required for the health of the mucus membranes in the digestive tract and helps with the absorption of iron and vitamin B6. Although it is needed for periods of rapid growth, it is also needed when protein intake is high, and is most beneficial to the skin, hair and nails.

Question: Where is Collagen Cross Linking with Riboflavin approved? I mean approved beyond testing needs. In Canada we must demonstrate the treatment is not experimental in order for it to be covered under our public health insurance. So I'm looking for where it has been approved beyond clinical testing.

Answer: A developing keratoconus treatment is Corneal Collagen Crosslinking with Riboflavin (C3-R®), that has been proven to strengthen the weak corneal structure. This method works by increasing collagen crosslinking, which are the natural "anchors" within the cornea. These anchors are responsible for preventing the cornea from bulging out and becoming steep and irregular, consequence of advanced keratoconus. Keratoconus is a disease of the cornea that makes the cornea become weak and may gradually bulge outward. Most often, this bulging is in the lower half of the cornea and first presents as astigmatism, however not all astigmatism is due to keratoconus. In mild or early stages of keratoconus (forme fruste keratoconus), eyeglasses may correct the astigmatic vision. The 30-minute corneal crosslinking treatment is performed in the doctor's office. During the treatment, custom-made riboflavin eye drops are applied to the cornea, which is then activated by ultraviolet light. This amazingly simple process has been shown in laboratory and clinical studies to increase the amount of collagen cross-linking in the cornea and strengthen the cornea. In published European studies, such treatments were proven safe and effective in patients. The abnormal curvature of the cornea due to keratoconus changes the cornea’s refractive error producing moderate to severe blurriness of vision. As keratoconus advances, rigid gas-permeable (RGP) contact lenses maybe the only non-surgical way to achieve clear vision. If keratoconus continues to advance, scarring of the central cornea may occur. Approximately half of keratoconus patients have no negative lifestyle effects beyond corrective lenses. The cornea stabilizes after a few years without ever causing severe vision problems. For others, the only resolution to keratoconus has been PKP, with a long healing period and unpredictable refractive error. Even after corneal transplant PKP, keratoconus can reoccur in the new donor cornea. Fortunately, there are two new methods to treat keratoconus that are much less invasive than a corneal transplant. An established treatment for keratoconus is Intacs. Intacs are a medical device approved by the FDA for the correction of 1.00 to 3.00 diopters of myopia (nearsighted, shortsighted) and virtually no astigmatism. Intacs inserts are the only refractive surgery procedure that adds structural integrity to the cornea. This unique attribute made Intacs an ideal treatment for keratoconus. Intacs are clear small semicircular plastic rings of various thickness that are inserted within the cornea at its outer edges. Insertion of these rings flatten the central area of the cornea and correct myopic refractive error. A major advantage of Intacs is that no tissue is removed and there is no ablation or incision across the visual axis. Intacs surgery is not truly reversible because of the incision, but the Intacs can be completely removed or exchanged for a different size. Intacs inserts cannot be felt by the patient and are no more visible than a contact lens. After insertion and healing, Intacs require no maintenance. The placement of Intacs inserts remodels and reinforces the cornea, eliminating some or all of the irregularities caused by keratoconus. Follow-up visits will be required to monitor the healing process and to evaluate the visual benefits of the procedure. Even after a successful Intacs procedure for keratoconus, glasses or contacts may be required, however Intacs have been shown to improve vision and reduce or stop the progression of keratoconus, thereby saving the patient from needing PKP. Intacs have been approved for the treatment of keratoconus by the FDA under a Humanitarian Device Exemption (HDE) Humanitarian Use Devices (HUDs) are medical devices specially designated by the FDA for use in the treatment of fewer than 4000 patients per year with rare medical conditions. Corneal crosslinking treatments can be combined with Intacs to flatten the keratoconus cone even more than with Intacs alone. In these cases, corneal crosslinking treatments stabilize keratoconus from getting worse as well as help the Intacs reverse the keratoconus steepening that had already occurred.

Question: What problems would be encountered in obtaining a spectrum of riboflavin below 250nm?

Answer: Below 250nm, water, carbon dioxide and nitrogen absorb, so the spectrum would be impossible to interpret if it's not taken inside a high vacuum. This, for a UV spectra.

Question: What are the effects of lacking Thiamin and Riboflavin?

Answer: you will get tired easily

Question: Is Riboflavin and Magnesium 500 harsh on stomach? Or do you have to take it with food? I'm asking this for a person who had stomach problems, so they can't take Advil, and other meds harsh on stomach without food. Thanks! I mean Magnesium 500 mg

Answer: I have taken both for several months now. I take 400mg prescribed magnesium and get my riboflavin in a B Complex formula by Nature Made. I have had not problems taking it at any time, although I often take it right before eating. I do, however, get nauseated taking calcium, so I'm not immune to that problem. Maybe just try taking it with a little something like a couple of crackers or few bites of yogurt first to see what happens.
