My Least Glamorous Health Habit (And Why It Works)

Do you know how much water you actually drank yesterday? Not how much you meant to drink. How much you actually drank.

I don't. Or, rather, I do—and it's suboptimal. On a busy day, I can get to 2 p.m. on coffee and a few sips of whatever's on my desk. I have had three dehydration-induced kidney stones. I have a master's in nutrition. I have recommended good hydration to millions of people. And I still arrive at 4 p.m. with a little energy slump and sometimes a mild headache, hunting around for what went wrong.

So let's talk about it, because it's boring, and boring is often the sweet spot of medicine and health.

How much water do we actually need?

The National Academies put adequate total water intake for women at about 2.7 liters a day, with roughly 20% of that coming from food.

But the number isn't the interesting part—it’s that thirst is an unreliable alarm system, and it gets less reliable with age. After 50, several things shift at once: thirst perception blunts, the kidneys get less efficient at concentrating urine, and total body water drops along with muscle mass. Add a diuretic or a blood pressure medication, add night sweats, add the fact that most of us have quietly organized our lives around never needing a bathroom at an inconvenient moment, and the result is a woman who is mildly, chronically underhydrated and has no idea.

Mild is the operative word. This is not dehydration to the point of needing IV fluids. This is the 1 to 2% fluid deficit that shows up as fatigue, headache, poor concentration, irritability, and constipation, and that most of us file under "I'm 57" or "I slept badly." Studies of mild dehydration in women have found measurable dips in mood and cognitive performance. I file it under a small thing that can feel like a big thing.

Where electrolytes come in

Here's the piece people miss: Sometimes water alone isn't the fix. Sodium and potassium are what allow fluid to stay where you put it instead of passing straight through you. It's why a big glass of plain water at 3 p.m. can send you to the bathroom 20 minutes later and leave you no less foggy than before.

You don't need much. A small amount of sodium, potassium, and magnesium alongside your water changes how much of it you keep, and, in my experience, changes how the back half of your day feels.

I've been using Pique's new X·E Fountain for this. It's a single-serve sachet of energizing electrolyte powder you stir into 12 to 16 ounces of cold water, containing: 150 mg sodium, 150 mg potassium (which is great for blood pressure), 30 mg calcium (enough to matter, but not so much that it can be linked with a sudden surge in serum calcium level), and 80 mg of magnesium in two well-absorbed forms. No caffeine, no sugar, no chemical flavoring. It tastes like cucumber, celery, and lime, which sounds like a spa cliché, but it’s genuinely the reason I finish the glass. It’s what I consider to be a true wellness supplement: I would be fine without it, but I feel I’m better WITH it! Let me tell you why.

The B vitamins

X·E Fountain delivers a full methylated B complex, including 500 mcg of B12 as methylcobalamin and folate as L-5-MTHF.

Let me be precise here, because this is where wellness marketing tends to overreach. B vitamins do not “create” energy. They're the cofactors that let your cells convert the food you've already eaten into usable energy, which is a good thing. If your levels are fine, more B will not give you a lift since once those receptors are full, they’re full. But many of us may not have adequate levels; I used to routinely screen my patients for B12 deficiency and I would pick up a lot of low and low/normal levels.

This matters at our age for a specific reason: B12 absorption declines after 50 as stomach acid production drops, and it declines further if you take metformin or a daily acid reducer, which many people do. In menopausal women, low and low/normal B12 levels look exactly like the fatigue and brain fog we're inclined to blame on menopause alone. So, this is a level worth checking and a conversation worth having with your doctor.

The bottom line

An electrolyte sachet is not a health intervention. Hydration is. If the taste of that electrolyte sachet alone is what gets you to drink nine cups of water instead of four, it’s doing real work. It’s the least glamorous mechanism in all of medicine: actually doing the thing. In this way, I see drinking some electrolytes as a health habit. For me, this is now automatically part of my daily routine, and I really feel good about it.

One caution: If you have kidney disease or heart failure, or if you take a potassium-sparing diuretic or an ACE inhibitor, added potassium and sodium are not automatically harmless for you. Ask your doctor first.
