We’ve all been there—staring at a screen with twenty open tabs, trying to figure out why our shoulders are up by our ears and why we can’t seem to catch a full breath. When we start looking for a way to turn down the volume on that internal screaming, magnesium is usually the first thing that pops up. But then it gets confusing. We see magnesium citrate, magnesium sulfate, and magnesium chloride, and suddenly, trying to relax feels like a chemistry homework assignment we didn't study for.
Many of us go looking for magnesium citrate bath salts because we know citrate is the "gold standard" for oral supplements. It’s what we take when we’re feeling backed up or want a quick boost. However, when it comes to soaking in a tub, the rules of the game change. At Flewd Stresscare, we’ve spent a lot of time obsessing over which minerals actually make it through the skin and into our systems.
This post is gonna break down why the form of magnesium we choose matters, why citrate might not be the best choice for your tub, and how we can actually use transdermal (through the skin) nutrients to kick stress to the curb. We’re in this together, so let’s get into the science of the soak.
Can't decide? You don't have to! Give all four soaks a try with the soak stan favorite, the Stresscare Sampler 12-pack.

When we talk about magnesium, we aren't just talking about one single thing. It’s like saying "pasta"—sure, it’s all dough, but you wouldn’t use spaghetti noodles to make lasagna. Different forms of magnesium are "bound" to different carriers, and those carriers determine how our bodies handle them.
This is magnesium bound with citric acid. It’s incredibly popular as an oral supplement because it’s highly bioavailable—meaning our guts can absorb it easily. The magnesium chloride vs. magnesium citrate comparison shows why that matters. However, when it’s tossed into bathwater, it’s not quite as effective at penetrating the skin barrier as other forms.
This is the Epsom salt we grew up with. It’s magnesium bound with sulfur and oxygen. It’s fine, it’s cheap, and it’s been around forever. But it’s also the "entry-level" version of a mineral bath. It leaves our skin feeling a bit dry sometimes, and it doesn't stay in our systems for very long.
This is the heavy hitter. It’s the form we use in our soaks because it’s the most bioavailable form for transdermal absorption. It’s a "wet" salt, meaning it naturally attracts moisture, which makes it much easier for our skin to drink it in. If we want our soak to actually do something for our stress levels for more than ten minutes, this is the one we want.
It makes total sense why we’d search for magnesium citrate bath salts. We’ve been told for years that citrate is the most "absorbable" version. And that’s true—if we’re eating it. Our digestive systems love citrate. But our skin is a different story.
Our skin is designed to keep things out. It’s a barrier, not a sponge. To get a mineral through that barrier, it needs to be in a form that the skin recognizes and allows to pass. Magnesium chloride mimics the natural mineral salts found in our own bodies and in the ocean, making it the VIP guest that gets past the bouncer.
If we try to use citrate in the bath, we might get some benefits from the warm water, but we’re likely missing out on the deep, cellular replenishment we’re actually after. It’s a bit like trying to charge a phone with the wrong cable—the effort is there, but the battery isn’t filling up.
Key Takeaway: While magnesium citrate is great for our guts, magnesium chloride is the superior choice for our skin. If we want a soak that actually reaches our nervous system, we need to choose the right mineral "key" for the lock.
One of the biggest reasons we prefer soaking over swallowing pills is that oral magnesium can be... well, a bit aggressive. If we take too much magnesium citrate orally, we’re probably gonna spend the rest of the evening in the bathroom. It has a notorious laxative effect.
By using transdermal absorption—which is just a fancy way of saying "through the skin"—we bypass the digestive tract entirely. This means:
When we’re suuuuuper stressed, our bodies burn through magnesium like a forest fire. Our nervous system uses it to regulate cortisol (the stress hormone) and keep us from feeling like we’re constantly under attack. Bathing allows us to replenish those stores in a way that feels like a treat, not a chore.
We don't believe in "one size fits all" when it comes to feeling like a human again. Stress shows up differently for everyone. For some of us, it’s a racing heart and a brain that won’t shut up. For others, it’s a heavy, "gray" feeling or muscles that feel like they’ve been tied in knots.
That’s why we didn't just stop at magnesium. Every one of our soaks is built on a foundation of magnesium chloride hexahydrate, but then we add targeted nutrients to hit specific symptoms.
Our Anxiety Destroying Soak is designed for those moments when we’re vibrating with nervous energy. We pair the magnesium with zinc and a B-vitamin complex. Zinc is like a volume knob for the brain—it helps calm the excitatory signals that keep us on edge. It’s a 15-minute reset that helps us feel like we’re back in our own bodies.
If we’re staring at the ceiling at 3:00 AM, the Insomnia Ending Soak is our go-to. We add vitamins A and E along with L-carnitine to the magnesium base. It’s designed to prep the body for deep, restorative rest without the morning grogginess that comes with some sleep aids.
Stress isn't just in our heads; it’s in our necks, our backs, and our joints. The Ache Erasing Soak uses vitamins C and D plus omega-3s to support muscle recovery and reduce inflammation. It’s for when we’ve been carrying the weight of the week on our shoulders.
If we’re gonna take the time to run a bath, we should probably make sure it actually works. It doesn't have to be a whole "wellness ritual" with thirty candles and a silk robe (unless that’s your vibe, then go for it). It just needs to be effective.
The term "bath salts" has been ruined by everything from cheap drugstore brands that are 90% table salt to, well, other things we won't mention. Most "magnesium citrate bath salts" or Epsom salts on the market are just that—salts. They might smell nice, but they aren't delivering a therapeutic dose of anything.
At Flewd, we call our products "transdermal nutrient treatments" because they’re more like a liquid vitamin for your skin than a bag of salt. We use 99% natural, non-toxic, and vegan ingredients. We also made sure our formulas are biodegradable because we care about the water we’re draining as much as the water we’re soaking in.
We’re tired of the wellness industry making us feel like we’re "failing" at being healthy. Stress is a natural response to a chaotic world. Our bodies are just trying to protect us. When we give them the nutrients they need, we’re not "fixing" ourselves—we’re just giving our systems the resources to handle the chaos a little better.
If you’re still dead-set on finding magnesium citrate bath salts, you might find some "fizzing" bath products that use citric acid and magnesium carbonate. When these hit the water, they react to create a form of magnesium citrate. While it’s a fun science experiment, it’s still not as bioavailable for your skin as chloride.
If you want the benefits of citrate, our advice is to keep it in your supplement cabinet for oral use. When you’re ready to get in the tub, reach for the chloride. It’s about using the right tool for the job.
Key Takeaway: Don't get bogged down in the marketing. Look for the science. Magnesium chloride hexahydrate is the most efficient way to get magnesium through your skin and into your life.
We often talk about stress like it’s a personal failing. Like if we just meditated more or ate more kale, we wouldn't feel this way. But the truth is, our biology hasn't caught up to our technology. Our brains treat a snarky Slack message from a boss with the same "fight or flight" intensity that our ancestors used for actual lions.
When that "fight or flight" response stays on for too long, it drains our magnesium, disrupts our sleep, and makes our muscles ache. It’s a physical depletion. We can’t always change the stressors—the bills, the jobs, the news—but we can change how much fuel our bodies have to deal with them.
Soaking in a high-quality magnesium bath isn't just "pampering." It’s a tactical refill for our stress response. It’s telling our nervous system, "Hey, we’re safe, we have what we need, and we can take a second to breathe."
While the magnesium chloride is the star of the show, we knew we had to go further. We live in a world that’s constantly asking for our attention. Our formulas are designed to be an all-in-one solution so we don't have to think. We don't have to measure out five different oils and three different powders. We just rip open a packet, pour it in, and let the science do the work.
We’re also pretty proud of being eco-friendly. Our packaging is recyclable and our shipping materials are biodegradable. We use 100% PCR (post-consumer recycled) materials because we know that environmental stress is real, too. We want to help you feel better without making the planet feel worse.
If you’re new to the world of transdermal nutrients, you might not know where to start. We usually recommend the Stresscare Trio, which gives you a taste of our most popular formulas (Anxiety, Insomnia, and Aches). It’s a great way to see how different nutrient blends affect your mood and body.
Remember, you aren't "broken" because you're stressed. You’re just human. And humans work better when they aren't running on empty. Whether you’re dealing with a "Sads" day or a "Rage" day (yes, we have soaks for those too), there’s a specific nutrient profile that can help support your system.
Our Rage Squashing Soak uses chromium and B12 to help level out those spikes of frustration that make us want to throw our phones out the window. On the flip side, our Sads Smashing Soak uses vitamins B3 and B6 along with nootropics to help lift that heavy, unmotivated feeling.
Magnesium is an essential part of the human experience, especially when that experience feels overwhelming. While magnesium citrate bath salts might be what people search for, the science points us toward magnesium chloride hexahydrate for the best results in the tub. By bypassing the gut and feeding our skin directly, we can replenish our stores, calm our nerves, and actually get some sleep.
Stress is inevitable, but staying depleted doesn't have to be. Take 15 minutes, get in the water, and let us help you refill your tank.
"We can't stop the world from being stressful, but we can stop stress from being the only thing we feel."

Technically, you can, but it isn't the most effective way to absorb the mineral through your skin. Magnesium citrate is designed for digestive absorption, whereas magnesium chloride hexahydrate is specifically structured for transdermal (skin) delivery. You're better off taking the citrate orally and using a chloride-based soak for your bath.
Epsom salt is magnesium sulfate, while magnesium chloride is a different compound that is more easily absorbed by human skin. Magnesium chloride is also less drying to the skin and tends to stay in the body's system longer than sulfate. It's essentially a more potent, "upgraded" version of the traditional bath salt.
Unlike oral magnesium citrate, which has a strong laxative effect, magnesium baths bypass the digestive system. This means you can get the relaxation and mineral benefits without the risk of stomach upset or urgent trips to the bathroom. It's a much gentler way to top up your mineral levels.
For the best results, we recommend soaking two to three times a week. This helps maintain consistent magnesium levels in your system, especially during high-stress periods. However, even a single soak can provide immediate relief for muscle tension and anxiety on a particularly rough day.
