We’ve all been there—staring at a laptop screen with a neck that feels like it’s made of dry kindling, or lying in bed at 2:00 AM wondering why our brains won't just stop talking. Modern life is essentially a series of events designed to drain us of our patience and our nutrients. When we feel that specific kind of "tired-but-wired" exhaustion, our bodies are often sending us a signal that they’ve run out of the mineral that keeps everything running smoothly: magnesium.
While we specialize in making targeted transdermal treatments at Flewd Stresscare, we also know that sometimes you just want to get into the lab—or your kitchen—and mix up something yourself. Making a DIY soak is a great way to take control of a stressful day. It’s a mindful process that rewards us with a suuuuuper relaxing result.
In this guide, we’re gonna break down why magnesium chloride is the king of bath ingredients, how to assemble a professional-grade recipe at home, and what specific additions can help with everything from racing thoughts to heavy legs. We’re covering the science of transdermal absorption (that's just a fancy way of saying "soaking things in through the skin") and giving you the exact steps to create a soak that actually does something.
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 most people think of a "salt bath," they think of Epsom salts. While those are fine, they aren't the top tier. Epsom salts are magnesium sulfate. Magnesium flakes, on the other hand, are magnesium chloride hexahydrate. This is a highly bioavailable form of magnesium, meaning our bodies can actually use it more efficiently when it’s absorbed through the skin.
Transdermal absorption is a brilliant shortcut. When we take magnesium supplements orally, they have to survive the gauntlet of the digestive system. For many of us, this causes stomach upset or just ends up being a waste because the gut doesn't absorb it well. By soaking, we bypass the stomach entirely. The magnesium moves through the skin and directly into the interstitial fluid and bloodstream.
Magnesium chloride hexahydrate is especially effective because it’s a more concentrated form of magnesium than sulfate. It’s also very hydroscopic—which is scientific talk for "it loves water." It dissolves almost instantly and feels "oily" or "silky" in the water, even though it contains no actual oil. This makes the bath feel like a spa treatment rather than just sitting in salty water.
Key Takeaway: Magnesium chloride is the most bioavailable form of topical magnesium. It’s more effective than Epsom salts for replenishing the mineral stores that stress steals from us.
Stress isn't just a "feeling"—it’s a physiological event. When we're stressed, our bodies pump out cortisol and adrenaline, and magnesium plays a major role in magnesium and stress relief. To manage those hormones, we burn through magnesium at an alarming rate. It’s a bit of a vicious cycle: stress causes magnesium loss, and low magnesium makes us more reactive to stress.
By using a magnesium flakes bath recipe, we’re essentially staging an intervention. We’re providing the body with the raw materials it needs to calm the nervous system and regulate the "fight or flight" response. This is why we feel that immediate "heavy" relaxation during a soak. Our muscles are finally getting the signal that they can stop holding onto tension.
Our skin is our largest organ, but it's also a gatekeeper. To get nutrients through it, the mineral needs to be in a form that the skin recognizes and allows to pass. Magnesium chloride hexahydrate is naturally occurring and matches the type of magnesium already found in our cells. This high bioavailability ensures that the 15 to 20 minutes we spend in the tub aren't just for show—they’re a functional nutrient delivery session.
If we’re going to do this DIY, we should do it right. This recipe is designed to be a solid foundation. From here, we can add targeted boosters depending on how we’re feeling.
At Flewd, we know that stress doesn't look the same for everyone. Sometimes it’s a racing heart and "the scaries," and other times it’s a deep, heavy sadness or a desire to throw a printer out a window. We can tailor our magnesium flakes bath recipe to meet these specific needs by adding secondary nutrients and aromatherapy.
When we feel anxious, our pulses are usually racing and our breathing is shallow. To support the body during these moments, we can add zinc and B-vitamins to our wellness routine. For the soak itself, we recommend:
Our Anxiety Destroying Bath Soak actually uses a combination of zinc and a B-vitamin complex for this very reason—it’s about more than just the magnesium.
If the day has been physically demanding or we’ve pushed ourselves too hard at the gym, we need to focus on recovery.
Insomnia is often just the final boss of a stressful day. To prep the body for sleep, we want to maximize relaxation.
While magnesium is the foundation, it works better when it has friends. This is a principle we use in every Flewd Stresscare formula. Complex B Vitamins are the "escort" for magnesium; they help the mineral move into the cells where it’s needed most. If we're making a DIY magnesium flakes bath recipe, we might consider taking a high-quality B-complex alongside our soak to maximize the benefits.
DIY projects are fun, but they can go wrong quickly if we ignore the science. Here are a few things we should avoid:
It’s tempting to turn the tub into a boiling cauldron, but very hot water actually makes it harder for the body to absorb minerals. It can also dry out the skin and leave us feeling drained rather than recharged. Aim for "bathwater warm"—somewhere around 100°F to 102°F.
We’ve mentioned this, but it’s worth repeating. Essential oils are powerful. If they float on the surface of the water, they can make direct contact with sensitive skin in high concentrations, leading to rashes or "burning" sensations. Always mix them with a carrier oil first.
The "sweet spot" for a magnesium soak is 15 to 30 minutes. After about 40 minutes, the body can actually start to re-absorb the toxins that the bath has helped pull out of the skin. Plus, let's be real—the water gets cold and the skin gets pruney. Keep it short and effective.
One of the best things about a magnesium chloride soak is that it leaves a bit of a mineral film on the skin that continues to absorb after the bath. You don't need to rinse off afterward. However, if the "silky" feeling of the magnesium bothers you, a quick 10-second rinse with cool water is fine. Just don't scrub yourself with soap immediately after.
Key Takeaway: For the best results, keep the water warm, use a carrier oil for your scents, and aim for a 20-minute soak to maximize nutrient absorption without drying out the skin.
We love a good DIY project. There’s something looooong and satisfying about measuring out ingredients and creating a custom jar of salts. However, there are some real-world downsides to the "kitchen chemistry" approach that we should talk about.
First, magnesium chloride is incredibly finicky. Because it’s so hydroscopic, it will clump into a rock-hard brick if there’s even a hint of humidity in the air. This makes storing a DIY recipe difficult unless you have laboratory-grade airtight containers.
Second, there’s the issue of sourcing. Most "bulk" magnesium flakes found online aren't tested for heavy metals or purity. When we’re soaking for 20 minutes, our skin is drinking in whatever is in that water. We have to be suuuuuper careful about the quality of the minerals we’re using.
Finally, a DIY recipe is usually just "magnesium plus scent." It lacks the targeted nutrient density that a professionally formulated soak provides. While a DIY soak is better than no soak, it won't have the specific ratios of amino acids, nootropics, and vitamins that we’ve spent years perfecting at Flewd.
If you’re reading this and thinking, "I just want to feel better, I don't want to start a side-hustle in bath salt manufacturing," that’s where we come in. We founded Flewd in 2020 because we realized everyone was stressed and no one had a simple, science-backed way to fix it.
Our soaks take the magnesium flakes bath recipe and turn it into a high-performance treatment. Every packet contains a massive dose of magnesium chloride hexahydrate, plus:
We’ve done the math so you don't have to. Instead of buying ten different ingredients and hoping the ratios are right, you just tear open a packet of something like our Sads Smashing Soak and dump it in. No clumping, no mess, and no guessing. Plus, our formulas are 99% natural, vegan, and biodegradable, so we're taking care of the planet while we take care of our stress.
Regardless of whether you use our packets or your own DIY recipe, the environment matters. Stress care is about creating a "container" for your nervous system to rest.
It’s helpful to think of our bodies like a battery. Every stressful email, traffic jam, or missed deadline is a "drain" on that battery. Magnesium is the "charge." Most of us are walking around at 10% battery life, wondering why everything feels so difficult.
When we use a bioavailable magnesium bath recipe, we aren't just "relaxing." We are literally recharging the cellular battery. This is why many people report that the effects of a single 15-minute Flewd soak can last for up to five days. We're filling the tank back up so we can handle whatever the world is gonna throw at us next.
If you’re ready to start your DIY journey, here is the quick-start checklist:
Stress is an unavoidable part of the human experience, but being depleted by it doesn't have to be. Whether we choose to spend a rainy afternoon crafting our own magnesium flakes bath recipe or we reach for a pre-measured packet from Flewd Stresscare, the goal is the same: giving our bodies the resources they need to find balance. We don't have to let stress run the show. By understanding the science of transdermal absorption and the power of magnesium, we're taking the first step toward a more resilient, calmer version of ourselves.
"The best way to manage stress is to stop treating it like a mental failing and start treating it like a nutrient deficiency. Feed your nervous system, and it will take care of the rest."

Yes, for the purpose of mineral absorption, magnesium chloride is generally considered more bioavailable. This means our bodies can absorb and use it more effectively through the skin compared to the magnesium sulfate found in Epsom salts. It also tends to be less drying for the skin.
Most people can safely enjoy a magnesium soak 3–4 times a week. If we're going through an exceptionally stressful period, a daily soak can be very supportive. However, it's always a good idea to listen to the body and consult with a healthcare professional if we have any underlying health conditions.
Even though they contain no actual oil, magnesium chloride flakes create a "silky" or slippery feel in the bathwater. This is simply a characteristic of the concentrated mineral solution. It’s actually quite beneficial for skin hydration and doesn't leave a greasy residue on the tub.
Many people report feeling a significant sense of relaxation and "heaviness" immediately after a soak, which can support falling asleep faster. For the best results, we recommend soaking about 30–60 minutes before bed and using grounding scents like cedarwood or Insomnia Ending Soak in the recipe.
