What is Your Pee Telling You?

Medically Reviewed by Dr. Bryan Seigel D.C., P.L.C.

Healthy urine should be a pale straw yellow — light, but not colourless. Dark yellow or amber usually means you need more fluid. Completely clear urine is a signal too: it often means you’re drinking more water than your body can use, and diluting the electrolytes in your blood along with it.

Two shades matter more than the rest: dark yellow that won’t clear no matter how much water you drink, and completely clear. Both point at the same thing, and it isn’t fluid. More on that below the chart.

Colour	What it usually means	What to do
	Clear — overhydrated. Very few solutes, and a high ratio of water to electrolytes in your blood.	Ease off the plain water. Replace minerals rather than adding more fluid. Fix this →
	Pale straw — this is the one you want. Well hydrated and in balance.	Nothing. Carry on.
	Transparent yellow — still perfectly healthy.	No action needed.
	Bright, neon or highlighter yellow — almost always riboflavin (vitamin B2) from a multivitamin, energy drink or electrolyte mix. Your body takes what it needs and flushes the rest.	Nothing. It looks alarming and it’s harmless.
	Dark yellow — mildly dehydrated. Too many solutes, not enough water to dilute them.	Add fluid over the next few hours. Still dark after that? Fix this →
	Amber or honey — dehydrated. Common after exercise, heat, alcohol, or a long stretch without drinking.	Rehydrate with water and electrolytes, not water alone. Fix this →
	Orange — often B vitamins or certain medications. Can also point to a liver or bile duct issue.	If you haven’t taken supplements or medication, speak to your doctor.
	Brown — severe dehydration, but also possible liver disease or muscle breakdown.	Speak to your doctor, especially if it persists after rehydrating.
	Pink or red — sometimes beets, blackberries or rhubarb. Otherwise it may be blood.	If you haven’t eaten those foods, contact your doctor. Blood in urine is never normal.

Still dark after drinking water? Here’s what’s going on

This is the one we hear about most. You’re drinking plenty — more than plenty — and it’s still coming out dark. It genuinely feels like the water is going straight through you.

In a way, it is. Water needs sodium, potassium and magnesium to stay in your system. When those run low, what you drink passes through instead of hydrating you. So you drink more, feel no better, and end up in a loop where the obvious fix keeps not working.

If that’s been your week, the thing to add isn’t another litre. It’s the minerals that let the water do its job. An electrolyte drink mix with all six minerals is the simplest way to break the loop, and you’ll usually notice the difference in colour within a day.

Worth knowing: it can take a few hours for that to show up. Here’s how long an electrolyte imbalance takes to correct once you start replacing what you’ve lost.

What’s in your pee?

Ideally, your pee is mostly water, so it should have a light yellowish color. Wastes are filtered by your kidneys and dissolved into a few different compounds your body produces, primarily the yellow-colored urobilin. Urine also contains excess salts and minerals, as well as byproducts from the normal detoxification processes of things that make their way into your bloodstream.

Why bright yellow pee usually isn’t a problem

If your urine has gone a startling neon or highlighter yellow, the culprit is almost always riboflavin — vitamin B2. It’s in most multivitamins, energy drinks, pre-workouts and electrolyte mixes, including ours. Riboflavin is water-soluble, so your body absorbs what it needs and sends the rest out. The colour is the leftover, doing exactly what it should.

It tends to show up an hour or two after you take something and fade over the day. If you’ve started a new supplement recently, that’s your answer. It isn’t a sign of dehydration, and it isn’t doing you any harm.

Your kidneys are a smart filter

Most people don’t spend too much time thinking about their kidneys, the organs that create the urine that gets stored in the bladder. Almost all of us are born with two of them, and they filter every drop of your blood about 40 times every day. They pull out wastes and enough water to dissolve them, and maintain fluid balance in our bodies. If you eat a very salty meal, you will retain more water because your kidneys are smart enough to keep that water in circulation to dilute the salt. The opposite is also true: having too little salt and other electrolytes means you’ll lose more water and get dehydrated, bringing on headaches and fatigue.

Ever drink a metric crap ton of coffee and find that your urine smells just like your morning cup of java? That’s because you’re drinking too much coffee at once! (No, don’t leave, hang on!) Your kidneys are pulling out unused molecules of caffeine, because there’s nowhere else in your body for them to go: you’re literally saturated! Because you’re going to the bathroom more often, your urine color will be pretty light, and that’s not the best either. So, slow down on the coffee intake and have a little water.

What color should urine be?

Some foods and food additives will change the color of your pee because the molecules containing these colors are small enough that they get through the kidney’s filter cells, or nephrons. You can turn your urine red or pink by eating beets, blackberries, or rhubarb. If you haven’t eaten these things and your urine is red, go talk to your doctor because that could be blood. There’s basically no situation where blood in your urine is OK.

Many B-vitamin supplements, along with some medications, will turn urine a bright orange color. Other medications can turn urine blue or green, as can certain food colorings. Brown urine can be caused by severe muscle damage and a number of diseases, so this is another case where a chat with your doctor is in order.

If your urine color is dark yellow or brown, it can be caused by foods or medications, but it’s more likely caused by not drinking enough water. Darker yellow urine usually indicates that there are too many solutes, or particles, contained in it, and not enough water to safely dilute them.

Why clear urine isn’t the goal either

Very light yellow or completely clear urine is a sign that you’re drinking more water than your body can use. Yes, that’s really a thing. Overhydration means that not only are there very few solutes in your urine, but that you have too high a ratio of water to electrolytes and minerals in your blood. Electrolytes are necessary for energy production, nerve conductivity, muscle function, and cellular health. There are documented cases of people drinking too much water and having severe or even deadly consequences from hyponatremia, which is too little sodium in the blood.

This is the part most hydration advice gets wrong. Both problems — urine that’s too dark and urine that’s too clear — come back to the same thing: the balance between water and minerals is off. Drinking more plain water fixes the first and makes the second worse. What actually restores balance is water with electrolytes in it. If you want to see how the options stack up, compare our electrolyte range.

Bottom line

It’s all about balance. Sometimes your urine will be a colour you don’t expect, and most of the time it comes down to fluid and minerals rather than anything worrying.

• Bright or neon yellow? That’s your vitamins. Nothing to do.
• Dark yellow or amber? Add fluid — and if you’ve been sweating, add electrolytes with it.
• Nearly colourless? Ease off the plain water and replace minerals instead.
• Pale straw? You’ve got it right.

A reasonable daily baseline for most people is around 64oz of water with electrolytes in at least one glass. Your needs shift with your size, how active you are and the weather, so treat the colour chart as your feedback loop rather than chasing a fixed number. If plain water never seems to touch your thirst, there’s a reason for that too.
