Constipation is one of the most frustrating symptoms for our clients. If you’ve been told magnesium will solve all your problems—only to still be bloated, irregular, and uncomfortable—you’re not alone.
While magnesium can help with motility, it’s not the whole story. It’s just one mineral in a much bigger symphony. And if the rest of your “orchestra” isn’t in tune, magnesium alone won’t bring harmony to your gut.
It’s also important to note: magnesium isn’t the strongest tool when it comes to truly moving the gut. While it can soften the stool by drawing water into the colon, it doesn’t stimulate gut movement as powerfully as other motility agents like ginger or prokinetics. That’s why increasing your magnesium dose often just results in loose stools—not the complete, satisfying bowel movements you’re actually looking for.
In this blog, we’ll break down why magnesium might not be working for your constipation—and what you actually need to look at to get lasting relief.
It’s Not Just Magnesium—It’s the Whole Mineral Symphony
Magnesium is a popular go-to for constipation, and for good reason: it helps draw water into the colon and stimulates peristalsis (the muscle contractions that move things along). But here’s the catch: your body doesn’t use magnesium in isolation.
For magnesium to be properly absorbed and utilized, your body also needs:
- Potassium, which helps move waste through the intestines
- Sodium, which supports hydration and muscle function
- Boron, which helps regulate magnesium metabolism
- Chloride and calcium, which work in tandem with nerve signaling and muscle contraction
When these minerals are out of balance, magnesium can’t do its job effectively. It’s like trying to play a piano concerto with a broken string section—something’s always going to feel off.
We often see this in clients who are taking 800, 1,000, or even 1,200 mg of magnesium daily—yet they’re still constipated. It’s not because they need more magnesium. It’s because they’re missing the key supporting minerals that allow magnesium to work as intended. Without that full mineral foundation, magnesium becomes a blunt tool instead of a precise solution.

3 Reasons Magnesium Might Not Be Working for Your Constipation
Even with enough magnesium (and even the “right kind”), you might still be stuck. Here’s why:
1. Your Minerals Are Out of Balance
In today’s world, mineral imbalances are more common than you think. Chronic stress, undereating, overtraining, certain medications (like birth control or PPIs), poor soil quality, a diet low in potassium and trace minerals, and drinking filtered water without replenishing minerals—these all deplete your reserves.
So even if you’re eating “healthy,” your body may not be getting or retaining what it needs. The old advice that “you don’t need a vitamin if you eat well” simply doesn’t hold up in our modern, fast-paced, depleted environment.
Magnesium is just one piece of the puzzle. We frequently see clients on HTMA tests showing high magnesium levels—but low potassium or sodium. This usually indicates the body is burning through magnesium under stress or that it can’t properly use it due to missing cofactors. It’s trying to compensate, but without enough support, the process can’t complete.
2. There’s a Deeper Gut Issue Going On
Minerals are foundational—but sometimes they’re just the beginning.
Yes, magnesium and its mineral co-factors are critical for things like producing stomach acid, digestive enzymes, and hormones. But if you’re dealing with poor absorption, gut inflammation, or chronic stress, your body may not be able to use those minerals effectively, even if you’re getting them in.
We often uncover deeper root causes that block digestion and motility altogether, such as:
- Low stomach acid, which slows digestion from the top down
- Slow motility, especially if the vagus nerve or thyroid isn’t functioning optimally
- Dysbiosis or bacterial overgrowth like methane SIBO, which actually slows transit time
- Poor bile flow, especially common if your gallbladder has been removed
These issues all create stress on the body—and stress further depletes minerals. So while we always start by rebuilding mineral reserves, it’s also essential to ask: what else could be disrupting digestion?
3. You’re Missing the Right Type or Dose
Not all magnesium supplements are created equal. Some are poorly absorbed. Some work more on calming the nervous system (like glycinate), while others support the bowels (like citrate or oxide). And your needs may vary depending on what your body is prioritizing.
For example, if your nervous system is in overdrive, you might need more calming support before your digestion responds. Or if you’re only taking 200–300 mg a day but are highly depleted, you might need a higher dose—sometimes up to 3–5x your body weight in mg (under practitioner guidance, of course).
That’s why using a blanket recommendation like “just take magnesium” rarely works. You need the right form, right dose, and the right supporting nutrients.
Conclusion: What to Do If Magnesium Isn’t Cutting It
If you’ve tried magnesium for constipation and still feel stuck, it’s time to zoom out and look at the full picture. Mineral balance matters—and often, what looks like a magnesium issue is actually a deeper imbalance or a hidden gut issue.
The good news? You don’t have to guess.
💧 Start with our free mineral guide—it’s packed with simple recipes, product links, and practical tips to start replenishing your minerals through food, drinks, and smart supplementation. It’s the perfect first step if you’re new to mineral support or just want to make sure you’re covering your bases. You can download it here.
🧪 Already tried minerals but still feel stuck? That’s where testing comes in. An HTMA (Hair Tissue Mineral Analysis) can reveal exactly what your mineral patterns look like—what you’re burning through too fast, what’s low, what’s compensating, and how your nervous system is handling stress. It’s one of our favorite tools for the client who has “tried everything” and needs clear direction, not more trial and error.
Magnesium alone won’t fix constipation—but understanding your mineral foundation (and where your body might need deeper gut or motility support) can help you finally get things moving—for good.
