Vitamin B-complex supplements include all the B vitamins including riboflavin, also called vitamin B-2. Riboflavin causes urine to turn bright yellow when you ingest it in excess. Your body requires riboflavin to break down carbohydrates, proteins and fats and release energy from those nutrients in all of your body’s cells. It assists with growth and production of red blood cells. Riboflavin also enables your body to use oxygen. Most people in the U.S. meet or exceed riboflavin recommendations, which vary from 0.3 mg per day to 1.1 mg per day, depending on age and gender, according to MedlinePlus. Riboflavin occurs in milk and dairy products, whole grains and dark green leafy vegetables, such as broccoli, turnip greens, asparagus and spinach. Eggs, lean meats, nuts and legumes also provide riboflavin. Breads and cereals may also be fortified with added riboflavin. Although milk and liver are the richest sources of riboflavin, nutritional yeast, dark green vegetables and whole or enriched grains provide an ample source for vegans who do not consume dairy products or meat.
Food processing may destroy some vitamins, but little riboflavin is lost during ordinary cooking because riboflavin is stable to heat. Ultraviolet light and irradiation destroy riboflavin, so milk is sold in cardboard or other opaque containers. Precautions must be taken when adding vitamin D to milk by irradiation, according to Eleanor Whitney, Ph.D., and Sharon Rolfes, M.S., R.D., authors of “Understanding Nutrition.” The vitamin B complex includes thiamin, riboflavin, niacin, biotin, pantothenic acid, vitamin B-6, folic acid and vitamin B-12. Vitamin and mineral supplements may be appropriate in some circumstances, such as to correct overt deficiencies and reduce the risk of certain diseases. At high or therapeutic doses, a supplement acts as a drug; use it only with the recommendation of your physician or registered dietitian. More than half of the U.S. population takes vitamin and mineral supplements regularly, and 1 in 5 people take a multinutrient supplement daily, as reported by Whitney and Rolfes.
B vitamins are water-soluble and move directly into the blood, where they travel freely throughout the body. Your kidneys detect excess riboflavin, which is excreted in the urine. This excess riboflavin, especially when you consume it in large doses, causes the urine to take on a characteristic bright yellow color. Consult your health care professional if you notice other unusual effects. Lack of riboflavin causes inflammation of membranes of the mouth, eyes, skin and gastrointestinal tract. Itching and burning eyes, sensitivity to light, reddening of your corneas, sore tongue, and itching or peeling skin and cracks in the corners of your mouth may occur. Your doctor or registered dietitian may recommend riboflavin. Treatment for a Riboflavin Deficiency What in Vitamins Makes My Urine Turn Yellow?

The darker the colour of the urine, the more concentrated it will be. Because people tend to sleep for several hours without having a drink, their urine is normally darker when urinating first thing in the morning.Darker urine during the day or evening can indicate dehydration, meaning you're not drinking enough fluids.
Drinking lots of fluids will make urine lighter. However, taking a diuretic, a medication to get rid of excess water in the body, also makes urine turn pale, as does diabetes insipidus, a rare type of diabetes.You may notice that when eating certain foods such as beetroot the colour of your urine changes - though this doesn't happen in everyone. Taking certain medications can also make the colour of urine change. Vitamin supplements may change the urine to a particularly bright colour. These changes, which are harmless, are due to the pigments and compounds in the food, supplements or medication. How much the colour of your urine changes will depend on how much food you eat or supplements or medication you take, how hydrated you are and on your own body chemistry.Sometimes a change in urine colour is an indication of a medical problem such as a urinary tract infection, urinary tract bleeding, or kidney, bladder or liver problem.The change in urine colour can indicate which food you have eaten, which medicine or supplement you took or a medical problem.

In the past the bites have blistered and sometimes swollen into very hot, itchy spots. I do take malaria tablets when required. On my most recent trip abroad to Spain, I was bitten again and the bites reacted as usual.Is there anything I can take before a trip that will stop such an adverse reaction to the bites?Insect bites can be very troublesome and if you are someone who frequently gets bitten and reacts badly to the bites it is worth doing all that you can to avoid being bitten.Insect repellent spray, and plug-in types of repellent can be very effective and covering up at times when bites are most common (early morning and evenings) is a good idea too.
In tropical places, avoiding bites is even more important because of the risk of catching insect-borne diseases such as malaria.Some people believe that taking vitamin B, eg in an oral vitamin B complex preparation may reduce the likelihood of being bitten. Apparently the vitamin is excreted in the sweat and puts off biting insects.There are no studies that support this claim, but you may like to try this. B vitamins should not be taken long term but taking them for a few weeks at a time would be safe.Try to avoid scratching any bites that you get as this does make the reaction worse.Antihistamine medications such as loratadine should ease the itching to some extent.An antihistamine cream specially designed for use on insect bites is also helpful. When you take a bath keep the water cool as heat will tend to make the itching worse.One thing that you need to be aware of is that bites do sometimes become infected. For this reason if you notice that the area around a bite is becoming very red, hot or swollen, it is always a good idea to arrange to see your GP or practice nurse so that they can check that this is not happening.
