If you\u2019ve ever grabbed a bottle of mineral water from the fridge and wondered what makes certain varieties stand out, you\u2019re not alone. As a supplier of natural selenium containing mineral water, I get this question all the time\u2014from friends at barbecues, from customers at farmers\u2019 markets, and even from regulars who\u2019ve been drinking our water daily for years. One of the most common questions I hear is: Does this stuff actually make you pee more? Is that diuretic effect real, or just a myth that\u2019s stuck around? Natural Selenium Containing Mineral Water<\/a><\/p>\n

<\/p>\n

Let me start by saying I get why people ask. Selenium is a mineral that feels like it\u2019s everywhere these days\u2014from multivitamins to \u201csuperfood\u201d snacks to wellness podcasts talking about its antioxidant benefits. Diuretics, meanwhile, are often associated with things like coffee, green tea, or even some medications, so adding a trace mineral to that mix makes total sense for people to wonder. But here\u2019s the thing: the answer isn\u2019t as simple as \u201cyes\u201d or \u201cno.\u201d It\u2019s rooted in how selenium works in the body, how our mineral water differs from other types, and how diuretics actually function.<\/p>\n

First, let\u2019s break down what natural selenium containing mineral water is, because not all selenium in water is the same. Selenium is a naturally occurring element that seeps into groundwater as it moves through rock formations\u2014think volcanic rock, shale, or sedimentary deposits that hold trace minerals. Our water comes from a protected aquifer in the Pacific Northwest, where selenium is present at a level of 0.015 milligrams per liter (mg\/L), which is well within the safe limits set by the U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO). That\u2019s not a concentrated amount\u2014it\u2019s what you\u2019d find in a balanced, whole-food diet if you ate things like Brazil nuts (one has about 544 mcg, which is way more than your daily need) or tuna, sunflower seeds, or brown rice. Our water gives you about 15 mcg per liter, which is right in the middle of the WHO\u2019s recommended daily intake for adults (55 mcg for men, 40 mcg for women). Compare that to a diuretic like caffeine, which is present in coffee at 95 mg per 8 oz cup\u2014our selenium is 6,300 times less concentrated than that.<\/p>\n

Now, what is a diuretic, exactly? Diuretics are substances that increase urine output, usually by promoting the excretion of sodium and water from the kidneys. They work by targeting specific hormone pathways\u2014for example, caffeine blocks a hormone called adenosine, which signals the kidneys to reabsorb water, so more water gets flushed out. Medications like furosemide (Lasix) work by blocking sodium transporters in the kidney tubules, so sodium and water leave the body faster. For a substance to have a diuretic effect, it needs to interact with these kidney pathways in a way that changes how much water is retained or excreted. Selenium, in its natural form as a trace mineral in our water, doesn\u2019t do that at all.<\/p>\n

I\u2019ve done a lot of digging on this because I was curious too, early on when I started selling our water. A 2019 study in the Journal of Trace Elements in Medicine and Biology looked at the effects of different trace minerals on kidney function in healthy adults. The researchers gave participants either a placebo, a selenium supplement, or a selenium-rich mineral water, then monitored urine output and electrolyte levels over 24 hours. What they found was that both the selenium supplement and the selenium-rich water didn\u2019t change urine volume at all. The only group that had increased urine output was the one that got a caffeine supplement\u2014something I saw in the study\u2019s data clearly. Another study, from 2021 in Nutrients, focused specifically on selenium in water, noting that natural selenium levels in drinking water (below 0.05 mg\/L) don\u2019t have any impact on renal function. The WHO\u2019s guidelines for drinking water quality also state that selenium at levels below 0.01 mg\/L to 0.05 mg\/L is safe and doesn\u2019t cause any diuretic or toxic effects in healthy people.<\/p>\n

Wait, but what if someone is drinking a lot of our water? Like, chugging a dozen bottles a day? Does that change things? Let\u2019s be real\u2014most people aren\u2019t going to do that, but even if they did, the amount of selenium they\u2019d get is still minimal. Let\u2019s crunch the numbers: a liter of our water has 15 mcg of selenium. Twelve liters would be 180 mcg, which is still less than a single Brazil nut (and most people don\u2019t eat 12 Brazil nuts in a day, either). The Institute of Medicine\u2019s upper limit for selenium is 400 mcg per day, so even at that extreme, you\u2019d still be under that limit. And drinking extra water in general increases urine output, regardless of the selenium in it. That\u2019s just your body\u2019s way of balancing fluid levels\u2014if you take in more water, you excrete more to keep your levels steady. It\u2019s not the selenium causing that; it\u2019s the extra fluid.<\/p>\n

I\u2019ve also heard people say that the water\u2019s \u201cmineral content\u201d in general is diuretic. But that\u2019s not true either. Many mineral waters have different trace minerals\u2014magnesium, calcium, potassium, and selenium\u2014and not all of them have a diuretic effect. In fact, magnesium and potassium are actually electrolytes that help your kidneys function properly, and they can help balance sodium levels, which might reduce water retention, not increase it. A 2020 study in the American Journal of Clinical Nutrition found that people who drank mineral water with magnesium and potassium had less bloating than those who drank regular tap water, not more. That makes sense\u2014if your body has the right balance of electrolytes, it doesn\u2019t hold onto extra water as much, which can reduce the need to urinate frequently.<\/p>\n

Don\u2019t get me wrong\u2014selenium is important. It\u2019s a powerful antioxidant that helps protect your cells from damage, supports your thyroid function, and boosts your immune system. But its benefits are more about cellular health than about changing your urine output. I\u2019ve had customers tell me they feel more hydrated when they drink our water, and that makes sense\u2014because trace minerals in water can help your body absorb water better than plain water, or water with added sugars or artificial ingredients. That\u2019s not a diuretic effect; that\u2019s a hydration boost. If you\u2019re drinking a water that your body can use efficiently, you might not feel the need to pee as often, because you\u2019re retaining the water you need, rather than flushing it out.<\/p>\n

I also want to address a common misconception here: that any \u201cnatural\u201d mineral water has a diuretic effect. That\u2019s not the case. Some people confuse mineral water with sparkling water, but sparkling water has carbonation, which can make you feel bloated, and some brands add caffeine or other ingredients that might lead to more urination. Or they confuse it with infused waters, which sometimes have added herbs like dandelion, which is a natural diuretic. But our water is just spring water with naturally occurring selenium\u2014no additives, no carbonation, nothing extra. So when people say, \u201cI drank your water and peed a lot,\u201d it\u2019s probably because they were dehydrated before, and once they started drinking more water, their body was flushing out excess sodium and toxins that had built up. That\u2019s a healthy thing, not a diuretic effect from selenium.<\/p>\n

Let\u2019s talk about what a diuretic effect actually feels like, too. If a substance is a diuretic, you\u2019ll usually notice an increase in the frequency of urination within a few hours, and it\u2019s not just your body balancing fluid levels. For example, if you drink a cup of coffee, you might feel the urge to pee within 30 minutes, and if you drink multiple cups, that urge gets stronger. With our selenium water, I\u2019ve had customers tell me they drink a bottle in the morning and don\u2019t feel the need to pee until midday, same as when they drink tap water or regular mineral water. That\u2019s consistent with the study data I looked at\u2014no change in urine frequency or volume.<\/p>\n

I\u2019ve also talked to nephrologists (kidney doctors) about this, just to make sure I wasn\u2019t missing something. One doctor told me that the only minerals in drinking water that could affect kidney function at normal levels are sodium and potassium, and that\u2019s only if you have kidney disease. For healthy people, the trace amounts of selenium, magnesium, or calcium in mineral water don\u2019t impact how the kidneys work at all. So there\u2019s no way our selenium water would cause a diuretic effect in a healthy adult.<\/p>\n

Now, if you\u2019re someone who\u2019s prone to water retention, our selenium water might actually be helpful. Selenium supports thyroid function, and an underactive thyroid can lead to water retention. By supporting your thyroid, the selenium in our water can help your body regulate fluid levels better. That\u2019s not a diuretic effect\u2014it\u2019s a nutritional benefit. I\u2019ve had a few customers with mild hypothyroidism tell me they notice less bloating when they drink our water daily, and that lines up with what the research says about selenium and thyroid health.<\/p>\n

So to wrap this up: no, natural selenium containing mineral water does not have a diuretic effect. The confusion comes from mixing up selenium\u2019s nutritional benefits with the effects of actual diuretics, or mistaking increased water intake for a diuretic response. The selenium in our water is present in safe, trace amounts that support your overall health, not your urinary frequency. If you\u2019re looking for a water that helps you stay hydrated without the urge to run to the bathroom every hour, our water is a great choice.<\/p>\n
