We’ve all been there—sitting at a desk, staring at an inbox that feels like a literal lion is chasing us, even though it’s just a bunch of passive-aggressive emails. Our bodies don't know the difference between a predator and a deadline; they just dump cortisol and use up our mineral reserves like they're going out of style. It’s a little ridiculous when we think about it, but the physical toll is real. That’s why we started Flewd Stresscare in 2020. We knew that people didn't need another complicated 10-step wellness routine; we needed a way to get essential nutrients back into our systems without the hassle of pills or the disappointment of standard bath salts.
In this guide, we’re gonna look at why magnesium flakes are the heavy hitters of the tub. We’ll explore the science of transdermal absorption (that’s just a fancy way of saying "soaking it in through the skin"), the major differences between flakes and Epsom salts, and how specific mineral blends can help us handle everything from 3:00 AM insomnia to those post-workout aches that make us walk like a baby giraffe. Magnesium is the foundation of over 300 biochemical reactions in our bodies, and when we’re stressed, it’s the first thing to go.
Can't decide? You don't have to! Give all four soaks a try with the soak stan favorite, the Stresscare Sampler 12-pack.

If we’ve ever bought a big, generic bag of salt for a buck at the drugstore, we’ve probably used Epsom salts. While they aren't "bad," they aren't the most efficient way to get magnesium into our systems. Epsom salt is magnesium sulfate. Magnesium flakes, on the other hand, are magnesium chloride—specifically, we use magnesium chloride hexahydrate.
The difference comes down to something called bioavailability. This is the measure of how much of a substance actually makes it into our bloodstream to do its job. Magnesium chloride is much more easily absorbed and utilized by our bodies than the sulfate version. Think of it like the difference between a high-speed internet connection and dial-up; both get us online, but one is clearly doing the job faster and better.
Furthermore, magnesium chloride is often harvested from ancient seabeds or deep underground deposits, making it a naturally occurring, mineral-rich compound. Because it’s highly soluble, it breaks its bonds quickly in warm water, allowing the magnesium ions to travel through our pores and into the dermal layers where they can actually go to work.
Key Takeaway: Magnesium flakes (magnesium chloride) are more bioavailable and concentrated than Epsom salts (magnesium sulfate), making them the superior choice for nutrient replenishment.
The idea of "eating through our skin" might sound like sci-fi, but our skin is actually our largest organ and a suuuuuper effective delivery system. Transdermal absorption allows us to bypass the digestive tract entirely. This is a massive win for a few reasons.
When we take oral magnesium supplements, they have to survive the harsh environment of our stomach acid and then be processed by the liver. For many of us, this can cause "gastrointestinal distress"—which is the polite way of saying it gives us the runs. Magnesium is a natural osmotic laxative, so if we take too much orally, it just flushes through us before we can actually absorb the benefits.
By soaking in a bath, we allow the minerals to enter through the skin and go straight to the interstitial fluid and blood vessels. We get the high-dose mineral replenishment we need without the unwanted bathroom breaks. It’s a cleaner, more direct route to our cells.
We use magnesium chloride hexahydrate because it stays stable and dissolves perfectly in warm water. When we step into a soak, the heat of the water causes our blood vessels to slightly dilate (vasodilation) and our pores to open up. This creates the perfect environment for magnesium ions to move from the high-concentration bath water into the lower-concentration environment of our skin.
Once inside, these ions help regulate our internal "calcium-magnesium pump." In our muscle cells, calcium is what causes a contraction, and magnesium is what tells the muscle to let go. If we don't have enough magnesium, our muscles stay in a state of micro-tension, leading to that tight, "shoulders-around-our-ears" feeling we all know too well.
When we talk about the benefits of magnesium flakes, we aren't just talking about a "nice smell." We’re talking about real, physiological changes that can support our wellbeing for up to five days after a single soak.
Whether we’re sore from a heavy lift or just stiff from sitting in a crappy office chair for eight hours, our muscles need magnesium to repair. When we're deficient, we might experience cramps, twitches, or general "heaviness" in our limbs.
Soaking in magnesium flakes may help:
For those days when the body feels particularly beat up, our Ache Erasing Soak combines magnesium chloride with vitamins C and D and omega-3s to target that physical fatigue head-on.
Stress is a nutrient thief. When our "fight or flight" system is stuck in the "on" position, our bodies burn through magnesium at an accelerated rate. This creates a vicious cycle: we’re stressed because we’re low on magnesium, and we’re low on magnesium because we’re stressed.
A magnesium-rich bath can help break this cycle by:
Most of us aren't just tired; we’re "wired and tired." We might fall asleep, but we don't stay in the deep, restorative phases of sleep looooong enough to actually feel rested. Magnesium plays a critical role in our circadian rhythm. It helps our bodies transition into sleep mode by regulating melatonin.
Our Insomnia Ending Soak is designed for this exact problem, blending magnesium with vitamins A and E and L-carnitine. Many of our users report that a soak before bed helps them drift off faster and reduces the "brain chatter" that keeps us awake at 2:00 AM.
Unlike traditional salt baths that can leave our skin feeling itchy, dry, and tight, magnesium chloride is actually quite hydrating. It helps support the skin’s natural barrier function and may improve hydration levels in the stratum corneum (the outermost layer of our skin).
For people with sensitive skin or conditions like eczema and psoriasis, magnesium baths may help:
We don't often think about our skin as a gateway to our mood, but the nutrients we absorb in the tub can have a profound effect on our mental state. Low magnesium levels are frequently linked to feelings of sadness, irritability, and "brain fog."
When we combine magnesium with targeted nootropics—compounds that support brain health—the results are even better. Our Anxiety Destroying Soak uses a zinc and B-vitamin complex alongside magnesium to help stabilize our mood and give our nervous system the "all clear" signal it’s been looking for.
Getting the most out of a magnesium soak isn't rocket science, but how much bath soak to use is worth knowing. We don't need a three-hour ritual; we just need 15 to 30 minutes of intentional soaking.
The "Do's" of Magnesium Bathing:
What to avoid:
At Flewd, we believe that taking care of ourselves shouldn't come at the expense of the planet. Most bath products are sold in bulky plastic jugs or non-recyclable foil pouches. We decided to do things differently.
Our formulas are 99% natural, vegan, and biodegradable. We use 100% PCR (post-consumer recycled) materials for our packaging, and our shipping materials are fully biodegradable. When we choose a transdermal soak over a shelf-stable liquid soap or a synthetic bath bomb, we’re choosing a product that’s better for our bodies and the ecosystem.
What to do next:
- Choose a soak based on your current primary stress symptom (anxiety, aches, sleep).
- Schedule a 15-minute block on your calendar for a "nutrient reset."
- Keep your magnesium flakes in a cool, dry place to prevent them from absorbing moisture from the air.
Magnesium flakes are more than just a luxury; they’re a functional tool for managing the physical and mental demands of modern life. By choosing magnesium chloride over inferior sulfates and utilizing the power of transdermal absorption, we can replenish our bodies’ most vital mineral in a way that’s fast, effective, and actually enjoyable.
Stress is inevitable, but staying depleted doesn't have to be. Whether we're using the Sads Smashing Soak to lift a heavy mood or a fragrance-free version for sensitive skin, the goal is the same: giving our bodies the resources they need to handle whatever life throws at us.
"We aren't just taking a bath; we’re performing a nutrient transfusion for our nervous system."

Magnesium flakes are made of magnesium chloride, while Epsom salts are magnesium sulfate. Magnesium chloride is more bioavailable, meaning our bodies can absorb and use it more effectively through the skin than the sulfate version found in Epsom salts.
For general wellness and stress maintenance, we recommend soaking 2–3 times per week. However, during periods of high stress, intense physical training, or poor sleep, many of our users find that soaking every other day provides the best cumulative benefits.
Yes, magnesium chloride is generally very soothing for the skin and can even help with hydration. If we're concerned about sensitivity, we should start with a shorter soak (10 minutes) and use one of our fragrance-free versions to avoid any potential irritation from essential oils.
A slight tingling sensation is completely normal and often indicates a low magnesium level in the body. As we replenish our mineral stores over several soaks, this sensation typically disappears as our skin and nervous system become more accustomed to the mineral intake.
