Sodium used to be something I barely thought about. Like many women trying to “do all the right things,” I ate whole foods, drank plenty of water, and avoided “bad” foods. On paper, it looked like a perfect routine. However, I was still having symptoms like low energy and sluggish digestion.
It wasn’t until I started digging into the science of minerals, especially sodium, that things began to click. For years we’ve been told that sodium is bad and something to be restricted. However, what I’ve learned (and experienced) over the years flips that advice on its head.
Sodium is one of the most foundational elements in how our bodies generate energy, communicate internally, and even feel safe at a nervous system level. For many of us, the real problem is that we’re not getting enough sodium.
Sodium: and Why Our Cells Crave it
When we hear the word “electrolytes,” it’s easy to think of sports drinks or hydration powders. But at a cellular level, electrolytes are something much more profound. They are what allows electricity to flow throughout the body.
Sodium, in particular, is one of the primary electrolytes. In simple terms, it carries a positive charge when dissolved in water. This charge is what allows it to conduct electricity. That’s incredibly important because the human body is, at its core, an electrical system.
Every thought, heartbeat, and movement depends on electrical signaling. Without adequate sodium, that signaling becomes less efficient. Research even shows that sodium and potassium ions are constantly moving across cellular and organelle membranes. This highlights just how deeply embedded these minerals are in cellular function.
From my own experience, this was one of the biggest mindset shifts. I stopped thinking about sodium as just something to sprinkle on food and started thinking of it as a conductor. It’s something that allows the body to function smoothly at every level.
Sodium For Cell Power
To understand why sodium matters so much, it helps to zoom in to the level of individual cells.
Every cell in the body maintains a delicate balance of sodium and potassium across its membrane. This balance, aka the sodium-potassium gradient, is what allows cells to generate electrical impulses. These impulses are essential for nearly every function in the body.
One of the most fascinating aspects of this is the sodium-potassium pump. This tiny but powerful mechanism uses energy (in the form of ATP) to push sodium out of the cell and pull potassium in. It’s estimated that this process alone uses a significant amount of the body’s energy, and up to half of our brain’s energy.
Not Getting Enough
That’s not a small detail. It means that maintaining proper sodium levels isn’t just helpful, it’s energetically prioritized by the body. And when our body is stressed and not getting the energy it needs, it deprioritizes other functions, like digestion and clear thinking.
When we don’t get enough sodium, several things start to break down, including:
- Electrical signaling becomes less efficient
- Cells struggle to regulate fluid balance
- Energy production may feel sluggish
- Brain function can feel “off” or foggy
- Digestion can feel slow
- Drier skin and hair from lack of true hydration
I noticed this personally. On days when I wasn’t getting enough sodium, especially if I’d been sweating or drinking more water than usual, I felt noticeably more fatigued and mentally slower. I noticed quite a difference when I started prioritizing getting more sodium.
Why “More Water” Isn’t Always Better
We’ve all heard the advice to “drink more water.” And while hydration is important, there’s a piece of the puzzle that often gets missed. Hydration isn’t just about water, it’s about balancing fluid and mineral levels.
Sodium plays a key role in regulating the body’s fluid levels, especially in the space outside our cells. When sodium levels drop too low relative to water intake, cells can begin to swell. This is especially significant in the brain, where even small changes in fluid balance can affect how we feel.
This can show up as:
- Headaches
- Brain fog
- Nausea or fatigue
- A general sense of feeling “off”
In some cases, what feels like dehydration may actually be the opposite, too much water without enough minerals. This was another area where my own habits needed adjusting. I’d been drinking a lot of plain water, thinking I was helping myself out. However, once I started adding minerals, especially sodium, I found I actually needed less water to feel hydrated.
Sodium and the Nervous System: A Hidden Safety Signal
One of the most interesting ideas I came across is that sodium can act as a “safety signal” for the body.
Good sodium levels support healthy blood volume and circulation. This helps the brain know that the body is in a stable, well-resourced state. When sodium is too low, the body may interpret this as a form of stress, even if we don’t feel stressed ourselves.
This can trigger symptoms that feel a lot like anxiety:
- Racing heart or palpitations
- Dizziness when standing
- Restlessness or unease
- Feeling tired but wired (fatigue paired with difficulty relaxing)
I noticed these symptoms, especially when I was doing all the “healthy” things (eating clean and exercising), but still felt off. In some cases, simply increasing sodium intake made a noticeable difference in how calm and stable I felt.
It’s a powerful reminder that the nervous system doesn’t just respond to thoughts or emotions. It also responds to physical inputs, like minerals.
Rethinking Sodium and Blood Pressure
For decades, sodium has been closely tied with high blood pressure. But when you look more closely at the research, the story becomes much more nuanced. It’s true that high sodium from processed foods, especially in the context of low potassium and low activity levels, can contribute to hypertension in some people. However, that’s not the full picture.
Some research suggests a J-shaped curve, where both very high and very low sodium intakes may be linked with increased health risks. In other words, too little sodium may be just as problematic as too much for certain people. Even more interesting, some experts estimate that about 75% of us may actually see stable or better blood pressure with higher sodium intake. Especially when this sodium comes from whole-food and is balanced with other minerals.
In my own family and clients I’ve worked with, I’ve seen this play out in real life. Focusing on a nutrient-dense diet, adequate mineral intake, consistent movement, and specifically increasing sodium didn’t raise blood pressure. Instead, there was real life data showing it had the opposite effect and improved blood pressure.
Of course, if you have any health condition it’s worth consulting with a natural healthcare professional you trust for targeted advice.
Why Modern Lifestyles May Deplete Sodium
One of the biggest disconnects in the sodium conversation is that our lifestyles have changed. An active person who lives in a hot climate or exercises or saunas can lose more minerals in five years than a person who doesn’t do these things will in their whole lifetime. And for anyone who prioritizes whole foods, we’ve eliminated the main source of sodium in modern diets: ultraprocessed foods (which is still a good thing!).
Many healthy habits can actually increase sodium loss:
- Regular exercise
- Sauna use
- Living in hot climates
- Pregnancy and breastfeeding
- Low-carb or ketogenic diets
- Chronic or underlying stress
Sweating alone leads to significant mineral loss. Add in stress, which can increase sodium excretion through the kidneys, and it’s easy to see how someone could become depleted.
This was definitely something I noticed. Between exercise, sauna use, and multiple pregnancies, I likely needed more minerals and sodium than most. And yet, like many women, I’d been conditioned to limit salt rather than consider whether I might need more. Interesting side note: my last pregnancy was by far my easiest, and this was after I started prioritizing sodium intake.
Choosing the Right Sources of Sodium
Not all sodium sources are created equal, and this is an important distinction.
Most of the sodium in the standard American diet comes from highly processed foods. These foods often combine sodium with refined ingredients, unhealthy fats, and additives. This also makes it difficult to isolate sodium as the sole issue. In contrast, using high-quality salt with whole foods creates a very different context.
Natural salts, like Himalayan or mined mineral salts, often contain trace minerals and are less processed than conventional table salt. However, even here, quality matters. Some sea salts have microplastics, while certain mined salts can have some levels of heavy metals, including lead. It’s worth doing your research and using what you’re comfortable with.
This is what I’ve been using lately:
How Much Sodium and Where to Get it
The US sodium guidelines suggest an upper limit of 2.3 grams per day, or about one teaspoon. However, the average person gets about 3.4 grams per day, mostly from ultraprocessed foods. But what is that sweet spot for optimal health?
It varies by person, but I try to get at least 5 grams a day, sometimes more. Podcast guest and research biochemist Robb Wolf gives a good explanation for why here.
Personally, I use well-sourced mineral salts and pair them with nutrient-dense foods. I also include naturally salty foods like fermented vegetables and broths, which provide sodium alongside other beneficial compounds. Here’s what else I do:
- Use healthy salt on seasonal, local foods to taste
- Mineralized water – I felt a big hydration difference when I started using the Mayu Swirl with minerals (code wellnessmama gives a discount)
- Using electrolytes and minerals like LMNT or trace minerals
- Drinking salted broth
- Eat naturally salty foods like olives, fermented veggies, and pickles, etc.
- Sip fermented pickled juice
- Salt tablets (I take these every day in addition to adding salt to food and drinks)
- Drink sole water first thing in the morning most days
Practical Ways to Support Healthy Sodium Levels
Rather than focusing on strict numbers, I’ve found it helpful to think in terms of context and feedback. Some simple approaches that have worked for me include:
- Paying attention to how I feel: Energy, clarity, and hydration cues
- Adjusting intake based on activity level, climate, and stress
One of the most helpful tools has simply been awareness. Noticing patterns, like feeling better with added electrolytes or worse after excessive plain water, can offer valuable clues.
Final Thoughts and A More Nuanced View of Sodium
Sodium is far more than a number on a nutrition label. It’s a foundational component of how the body functions, electrically, neurologically, and even emotionally. It’s responsible for powering cell communication, supporting fluid balance, nervous system stability, and so much more.
For many of us, especially those focused on whole foods and active lifestyles, the conversation needs to shift from restriction to optimization. The question shouldn’t be, how little sodium we can get away with? A better question is, how can we support our bodies with the right balance of minerals in the context of how we actually live?
Like so many aspects of health, the answer isn’t one-size-fits-all. But in my experience, and even more in the research, sodium deserves a second look.
