Urine contains large amounts of urea, an excellent source of nitrogen for plants. As such it is a useful accelerator for compost. Urea is 10,000 times less toxic than ammonia and is a byproduct of deamination (2 NH3 molecules) and cellular respiration's (1 CO2 molecule) products combining together. Other components include various inorganic salts such as sodium chloride (the discharge of sodium through urine is known as "natriuresis".)  The typical clear, yellow, or yellow-orange (usually a sign of dehydration) colour of urine is caused by the pigment urochrome, but also from the degradation products of bilirubin and urobilin.

I drink 16 ounces an hour, until I don't need it. Anymore than that can cause kidney damage. But that's the Military Standard in the U.S. The key is, you want to drink water until your urine is clear. Once it starts turning yellow again, start drinking. Make a habit out of it, and you won't have to pay attention. Remember, the more toxins you take in, the more water you will need, and the more often you will need to urinate. Try to eliminate caffeine, alcohol, etc. If you sweat more, drink more.

You may be slightly dehydrated.  Drinks fluids especially water. Your urine should be pale yellow normally.

Oddly enough, yes. Migrelief contains a suppliment called Riboflavin (also known as Vitamin B2). B vitamins are commonly known to turn urine very bright yellow, so not to worry. In fact, when I began taking a complex B vitamin, it was described to me by my nutritionist "Don't worry about your pee turning bright, neon yellow. It means that the B vitamins are working." \n\nOne thing I would be careful with though is if you are taking any complex B vitamins or Multivitamins that include B vitamins, not to upset the balance of B vitamins that your body is recieving. Not that this will be harmful, necessarily, but the B vitamins, if not balanced, can be much less helpful.

The answer could be a yes or a no! Urine is sterile before it exits the body. As soon as it exits the body its not longer sterile because it has come into contact with bacteria from the unrinary tract and the vagina/penis (which normally have some bacteria residing in them weather harmful or not).

That won't work, they'll know its been refrigerated. You'll have to drink your friends urine right before the test so that    the clean pee comes out of your body. Get all high and think about it, it will make sense then. Smoke a phat J and then guzzle some piss, works like a charm.

Large amounts of some vitamins can change the color of your urine...B12 for instance. It just means you are getting more of the vitamin than your body can use and it is eliminating it through the kidneys. It's harmless.

It's probably a urinary tract infection. It could involve your bladder, kidneys, etc... You do not want to let this go untreated. If your kidneys are involved, it could theoretically be life threatening. Even if they're not, you need antibiotics. Call and schedule an appointment with your doctor a.s.a.p., and in the meantime, drink plenty of water, urinate frequently, take cranberry pills, and avoid sugar. \n\nIncidentally, cranberry pills are better than cranberry juice because the juice has too much sugar in it, and sugar can aggravate a urinary tract infection. You can get cranberry pills in the section where vitamins are sold.

No one can really say it depends on your particular body type,you should test your the PH of your urine once every few months to see if your progressing.Also be cautious with juicing too many carrots because they are high in sugar and can turn you a horrid shade of yellow!

Urine pH as measured by urinalysis has a normal range of about 4.5-8 with a pH of 6 being the average. Neutral pH is 7. Anything having a lower pH is acidic and anything with a higher pH is basic. \nUrine is actually a fairly good growth medium for bacteria and is sometimes used in labs for this pupose. However urine with a lower pH (more acidic) has been found to inhibit the growth of bacteria. \nUrine that is high in ammonia on the other hand with its higher pH (more alkaline or basic) has been found to impede the bodies immune responce to a UTI. In fact Proteus species of bacteria which is a common cause of UTIs produces a substance called urease which breaks down uric acid (an end product of nitrogen metabolism found in urine) into ammonia and carbon dioxide, thus causing the urine to become more basic. The ability of Proteus of produce urease increases its ability to cause pylonephritis (infection of the kidney as opposed to the blatter or ureters).\nTaking substances that will alter the pH of your urine however may have unforseen side effects. The pH of the urine helps determine what is and what is not filtered out of the blood by the kidney. Also altering the pH will have an effect of the formation of kidney stones. Certain particles will become "un-dissolved" at a higher pH and some at a lower pH. If enough of the particles come out of solution, you will get kidney stones. In fact the Proteus bacteria that cause the urine to become more basic are associated with an increase in kidney stones.\nI general however pH has very little to do with get or not getting a UTI. The urinary tract from the distal urethra up is mostly sterile and the few bacteria that do get into the urinary tract are usually flushed out when you urinate. Some bacteria however such as E. coli have molecules on thier outer membrane that can adhere to the urinary tract lining. It can do this reguardless of pH and pH in general has little effect on E. coli which is what causes about 85% of UTIs not contracted in a hospital. E. coli is found in the digestive tract and most UTIs are caused when the E. coli finds its way into the urinary tract. While in the digestive tract the E. coli has had to endure the extremely acidic pH of the stomach and the very basic pH of the small intestine.\nMost bacteria that cause UTIs are from the digestive tract. Often they are aided in migration to the urethra by sexual intercourse. The use of spermicides is associated with an increase in UTIs because the protective bacteria of the vagina are killed by the spermicide and this leave the vagina vulnerable to colinization by UTI causing bacteria.\nAlso some women are genetically predisposed to UTI because they have more adhesion molecules on their vaginal walls.\nCranberry juice is helpful in preventing UTI. Studies have shown that cranberry juice inhibits the ability of bacteria to adhere to the urinary tract.\nIf recurrent UTIs are a problem you may want to speak to you doctor about methanamine. It is used to prevent UTIs especially those caused by E. coli which is the most common cause of UTIs.

Bilirubin gives the urine its yellowish tint. Bilirubin is a by product of red blood cell breakdown. The more concentrated the urine, the darker it is.

The kidneys serve two major functions: they keep the salt content of the blood constant, and they filter waste out of the bloodstream. So, the main components of urine are (salt) water and waste products. The major waste product from cells in the body is ammonia, and the major waste product from blood is a broken form of heme called bilirubin. In the liver, each of these is converted into a less hazardous form: ammonia is converted to urea, and bilirubin is degraded to urobilins. Salt, water, and urea are all colorless, but urobilins (which come from degraded pigments) are yellow. So, if you drink a lot, your urine will be more dilute and clearer, and if you get dehydrated, your urine will contain less water and be darker yellow.

In the medical laboratory a urine specimen received for analysis bearing the characteristics you describe could very well indicate a possible liver condition.  A deep yellow or brownish coloration may be due to bilirubin or excessive urobilinogen.  Also through my studies and experience a foamy urine also frequently indicates the prescence of bilirubin.  The smell could be due to infection.  Blood could also very well be found in a urine such as this.  I would think your best move would be to present this information to a medical doctor as soon as possible.  Even if nothing comes of it-I feel like there might be something going on that needs to be addressed quickly.  Better safe than sorry.

unless you have an infection, piss is actually sterile...

urine contains urea, which is a nitrous acid that is digested out of the bloodstream. when the urea mixes with the toilet water, it foams.

you'll have a lot of good ol' beta carotene in your system :) the worst thing i could think of is your skin or urine might look orangy. but that's just normal. sometimes i eat red beets and my pee turns red.

Generally speaking when your urine is dark you either have a UTI or are dehydrated, although this isn't always true.  Certain vitamins can give your urine a dark appearance also.  The clearer your urine the fewer toxins/wastes being excreted.  This could be due to drinking tons of water (not too much, can kill you if you drink too much) or just not having many toxins/wastes to eliminate from your body.
