We've all had those weeks where the brain feels like an over-caffeinated squirrel on a treadmill. Every email feels like a personal attack, the laundry is judging us from the corner, and "relaxing" feels like just another chore we're failing at. Most wellness advice tells us to just "breathe" or "go for a walk," but when we're running on fumes, we need something that actually gets under the hood and fixes the mechanics of our stress response.
At Flewd Stresscare, we started during the 2020 pandemic because we realized that stress isn't just a "feeling"—it's a physiological event that drains our bodies of the very nutrients we need to stay calm. This article explores why combining a magnesium and lithium bath soak is one of the most effective ways to hit the physiological reset button. We're gonna dive into the science of trace minerals, why the form of magnesium matters, and how a 15-minute soak can support our mental well-being for days.
By the end of this, we'll understand why these primordial minerals are the secret to going from weighed down to mellowed out.
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 hear "lithium," they think of heavy-duty pharmaceuticals or the batteries in their phones. But lithium is actually an ancient trace mineral that has been part of the human diet for as long as we've been around. It’s found in rocks, soil, and naturally occurring spring water. In fact, lithium was one of the first three elements created during the Big Bang. It’s suuuuuper old, and our bodies have evolved to use it in tiny, "trace" amounts to keep our nervous systems stable.
In the wellness world, we use something called Lithium Orotate. This is very different from the high-dose lithium carbonate used in clinical settings. Think of it like the difference between taking a multivitamin with a little bit of iron and undergoing a medical procedure for iron deficiency. Lithium orotate is lithium bound to orotic acid, which helps it cross the blood-brain barrier more efficiently. This means we can use much smaller, safer doses to get the calming effects we’re after.
Historically, people used to travel hundreds of miles to visit "Lithia Springs" to soak in mineral-rich water. Even the original recipe for 7-Up included lithium as a mood-boosting tonic. While we’ve moved away from putting minerals in our soda, the biological need for these trace elements hasn't changed. When we use lithium in a bath soak, we're essentially recreating those ancient healing springs in our own tubs. It’s designed to help calm the "noise" in our heads and support a more balanced emotional baseline.
If lithium is the "mood mineral," magnesium is the "everything mineral." It’s involved in over 300 biochemical reactions in our bodies, from muscle function to heart rhythm to—most importantly—how we handle stress. The problem is that when we’re stressed, stress depletes magnesium like a sports car burns through gas. We get stuck in a "stress loop": stress depletes magnesium, and low magnesium makes us more reactive to stress.
But not all magnesium is created equal. Most "store-bought" bath salts use magnesium sulfate, better known as Epsom salt vs magnesium chloride. While Epsom salt is fine for a basic soak, it’s not particularly bioavailable. This means our skin doesn't absorb it very well. We use magnesium chloride hexahydrate vs magnesium chloride in our formulas because it’s the most bioavailable form of magnesium for transdermal (through the skin) absorption.
Magnesium chloride is much closer to the type of magnesium naturally found in our bodies. When we soak in it, the magnesium doesn't have to wait to be processed by the digestive system. It passes through the skin and goes straight to work. It helps lower cortisol (the stress hormone), relaxes tight muscles, and tells the nervous system it’s safe to exit "fight or flight" mode.
Key Takeaway: Stress is a physical nutrient drain. Replacing magnesium and lithium through the skin is a direct-to-cell way to refill the tank and break the stress cycle.
Using magnesium and lithium together is like having a bodyguard and a therapist for our nervous system. Magnesium does the heavy lifting of relaxing the physical body and lowering the "volume" of our stress hormones. Lithium then steps in to support the brain’s "neuroprotective" pathways.
Research suggests that trace amounts of lithium may help support the formation of new brain cells and protect existing ones from the damaging effects of chronic stress. When we combine this with the muscle-relaxing power of magnesium chloride, we get a "top-down and bottom-up" approach to relaxation. The magnesium relaxes the body, which tells the brain it’s okay to chill, while the lithium helps the brain stay resilient against future stressors.
In our Sads Smashing soak, we don't just stop at minerals. We also include:
This combination is specifically designed for those days when we feel "weighed down"—that heavy, sluggish feeling where even small tasks feel like climbing a mountain. It’s not about a temporary "buzz"; it’s about giving our bodies the raw materials they need to function better.
Most of us have a cabinet full of supplements we forget to take, or that make our stomachs feel weird. When we swallow a pill, it has to survive stomach acid, pass through the liver, and navigate the entire digestive tract before it even gets to our bloodstream. By the time that happens, a huge chunk of the nutrients has been lost.
This is where transdermal magnesium uptake comes in. Our skin is our largest organ, and it’s surprisingly good at taking in minerals when the conditions are right. By soaking in a warm bath, we open our pores and allow the magnesium and lithium to bypass the "digestive tax" entirely. This is especially helpful for people with sensitive stomachs or those who are already sooooo overwhelmed that the idea of a 10-step supplement routine makes them want to scream.
A 15-to-30-minute soak is a concentrated nutrient treatment. Because the minerals are absorbed directly into the tissues, the effects often last much longer than a standard oral supplement—many of our users report feeling the "mellow" effect for up to five days after a single soak. It’s a "lazy" bio-hack that actually works.
Our nervous systems are a bit outdated. They haven't really caught up to the 21st century. When we get a passive-aggressive Slack message or see a scary news headline, our bodies react the same way they would if a literal lion were charging at us. Our heart rate spikes, our muscles tense up, and we dump our stores of magnesium and elemental zinc to power a "fight or flight" response.
The problem is, there’s no lion to fight and nowhere to run. We just sit at our desks, soaking in cortisol. Over time, this constant state of "high alert" leaves us feeling depleted, irritable, and physically sore.
Bathing in magnesium and lithium is a way of manually overriding that response. The warm water provides a sensory signal of safety, while the minerals provide the chemical signal of relaxation. We’re essentially telling our bodies, "The lion is gone. You can stand down now."
We don't use scent just to make the bathroom smell nice (although that’s a plus). We use specific fragrance profiles to trigger the limbic system—the part of the brain responsible for emotions and memory. Our Sads Smashing soak features a "Desert Rain" scent.
Think about that smell right after a storm hits dry earth. It’s fresh, grounding, and weirdly hopeful. By combining this olfactory (scent) trigger with the physical effects of magnesium and lithium, we’re creating a multi-sensory environment that helps pull us out of a mental rut. It’s about creating a "vibe" that matches the chemical work the minerals are doing in our bodies.
We’re big fans of being real here. A bath soak isn't going to fix a toxic job or pay our rent. It's not a "cure" for clinical conditions, and it’s definitely not a replacement for therapy or medical advice. What it is, however, is a high-performance maintenance tool.
Think of it like charging a phone. If the battery is at 1%, the phone is barely functional. A magnesium and lithium bath soak is like a fast-charger for our physiological battery. It gives us enough "charge" to handle the day-to-day chaos without short-circuiting. Results can vary, but most people find that regular soaks make their "baseline" feel a little more manageable. We're not looking for a "life-changing" miracle; we're looking for a "life-managing" edge.
We've mentioned this before, but it's worth repeating because the marketing for Epsom salts is everywhere. Epsom salt is magnesium sulfate. It’s cheap to produce and widely available, which is why it's the default in most drugstores. But in terms of actual mineral delivery, it's pretty "meh."
The sulfate molecule is quite large, making it harder for it to pass through the skin barrier. Magnesium chloride, on the other hand, is a smaller molecule and is much more "hygroscopic"—meaning it loves water and dissolves into a form that our skin can easily recognize and pull in.
If we're gonna take the time to run a bath and sit in it for 20 minutes, we might as well use something that actually delivers the goods. Most store-bought salts are also heavily processed and filled with synthetic fragrances that can irritate the skin. We keep our Flewd formulas 99% natural and non-toxic because the last thing a stressed-out body needs is more chemicals to process.
One of the things that makes us different is that we don't believe in a "one size fits all" approach to stress. Stress shows up differently for everyone. For some, it’s a racing heart and "spiraling" thoughts. For others, it’s a heavy, low-energy "rut."
That’s why we created specific formulas like our Anxiety Destroying Soak (with zinc and B-vitamins) and our Sads Smashing Soak (with lithium and nootropics). By targeting the specific nutrients that are most depleted by certain types of stress, we can provide more effective relief. We're not just making "bath salts"—we're making transdermal nutrient treatments.
Our packets are pre-measured to ensure we're getting a "therapeutic" dose of minerals. No guessing, no measuring, no wondering if we used enough. Just pour the whole packet in, get in the tub, and let the science do the work.
"We treat stress like a physical deficiency because, for the most part, that’s exactly what it is. If you're running low on the minerals that keep you calm, no amount of 'positive thinking' is going to help as much as just refilling the tank."
We know life is busy. The idea of a 30-minute bath can feel like a luxury we don't have time for. But when we look at the time we spend doom-scrolling or staring at the ceiling because we can't sleep, a how to use a bath soak is actually a time-saver.
If we can't manage a full bath every day, that’s okay. Even one "reset" soak on a Sunday night can set the tone for the rest of the week. Because the nutrients are absorbed and stored in our tissues, we don't need to do it every day to see the benefits. It’s about building a sustainable rhythm that works for our lives.
We also care about the planet we're all stressing out on. Our packaging is recyclable, our shipping materials are biodegradable, and we use 100% PCR (post-consumer recycled) materials where possible. We want the only thing we're leaving behind to be our stress, not more plastic waste.
For a long time, "self-care" was marketed as something superficial—a scented candle, a fluffy robe, a glass of wine. But the younger generations are smarter than that. We want things that actually do something. We want "wellness" that is backed by biology, not just "vibes."
A magnesium and lithium bath soak is the evolution of that. It takes the ancient wisdom of mineral springs and applies modern understanding of bioavailability and neurochemistry. It’s a way to take control of our physiology when our environment feels out of control.
We don't need to be "perfect" at health. We just need tools that help us navigate a stressful world with a little more ease. Whether we're dealing with a temporary slump or a high-pressure deadline, these minerals are here to help us keep our heads above water.
Stress is inevitable, but feeling depleted doesn't have to be. By understanding the science of magnesium and lithium, we can turn a simple bath into a powerful mood-supporting treatment. These minerals work together to relax our bodies, support our brains, and break the physiological cycle of stress.
If the brain is feeling heavy and the world feels loud, it might be time to stop fighting the feeling and start feeding the body what it’s missing. Grab a Sads Smashing soak or build your own bundle to find the formula that fits your specific brand of stress.
While trace lithium orotate in our soaks is a trace amount, most people find that using it 1–3 times a week is plenty to maintain a balanced mood. Because the minerals are stored in the body's tissues, the effects are cumulative and often last for several days.
Lithium carbonate is a high-dose medication used to treat diagnosed medical conditions under strict doctor supervision. Lithium orotate is a trace mineral used in much smaller, "micro-doses" to support general wellness and mood balance, similar to how one might use a zinc or magnesium supplement.
Yes, our formulas are 99% natural, paraben-free, and phthalate-free to minimize irritation. However, because magnesium is a salt, it can sometimes cause a slight tingling sensation on very dry or broken skin; if this happens, simply rinse off with fresh water after your soak.
Epsom salt (magnesium sulfate) is less bioavailable, meaning the body doesn't absorb the magnesium as efficiently as it does with magnesium chloride hexahydrate. Using magnesium chloride hexahydrate ensures you're actually getting the minerals into your system rather than just soaking in salty water.
