We’ve all had those weeks where the world feels about ten shades of grey. It isn’t just that we’re tired; it’s that we feel heavy. Our bodies treat a passive-aggressive Slack message with the same biological panic they’d use for a literal lion, and after a while, our internal resources just bottom out. When our "check engine" light starts flashing, most of us reach for another coffee or scroll through social media, but our nervous systems are actually screaming for minerals.
Specifically, we’re often missing two heavy hitters: magnesium and lithium. While magnesium has finally gotten the spotlight it deserves, lithium is the quiet overachiever that people are just starting to rediscover. At Flewd Stresscare, we looked at the science of how these minerals work together to help us find our footing when life gets overwhelming. We aren't just talking about a bubbly soak; we’re talking about transdermal magnesium uptake that helps us feel like ourselves again.
This post covers why magnesium and lithium bath salts are becoming the go-to for anyone dealing with emotional burnout, how they actually get into our systems, and why the history of these minerals is way more interesting than we were taught in chemistry class. We’re going to explore how a simple 15-minute soak can help us move from "barely hanging on" to "actually okay."
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 stress, we usually talk about it as a feeling. But for our bodies, stress is a high-speed chemical transaction. Every time we get stressed, our bodies burn through bioavailable magnesium like it’s high-octane fuel. Magnesium is responsible for over 300 biochemical reactions in our bodies, including the ones that tell our nervous systems to chill out. When we run low, we don't just feel "stressed"—we feel twitchy, anxious, and physically exhausted.
Then there’s the emotional weight. Sometimes we aren't just anxious; we’re stuck in a "sad rut" where everything feels difficult. This is where lithium comes into play. In the wellness world, we’re seeing a massive resurgence in the use of micro-dose lithium (specifically lithium orotate) because of its ability to support mood stability and brain health. It isn't about "fixing" a condition; it’s about providing our brains with a trace mineral that we used to get plenty of from our water and soil, but now lack because of modern farming and water filtration.
When we combine these two in a bath, we’re creating a concentrated mineral delivery system. Instead of waiting for a pill to make its way through our digestive tract—where much of the mineral content gets lost—we’re letting our skin take the lead. It’s a direct, efficient way to refill our tanks.
To understand what we’re putting in our tubs, we have to look at the forms of these minerals. Not all salts are created equal, and if we’re looking for actual stress relief, we need to go beyond the cheap bags of the Epsom salt comparison found in the grocery store aisle.
Magnesium in these soaks is usually found as magnesium chloride or magnesium sulfate (Epsom salts). At Flewd, we focus on magnesium chloride hexahydrate. It’s the most bioavailable form of magnesium for our skin, meaning our bodies can actually use it rather than just letting it sit on the surface. It’s "wetter" than other salts and absorbs much more efficiently into our tissues.
Lithium in a bath context is almost always lithium orotate. This is a salt formed by combining lithium with orotic acid. Don't let the word "acid" freak you out—it’s a natural substance found in our bodies. Lithium orotate is used in tiny, "micro" amounts. It isn't the same as high-dose pharmaceutical lithium used in clinical settings. Think of it more like a vitamin or a trace mineral that helps our brain cells communicate more effectively.
The Big Idea: Magnesium calms the body, while lithium stabilizes the mind. Using them together in a soak creates a dual-action approach to stress that single-mineral salts just can’t match.
It sounds suuuuureal now, but lithium used to be everywhere. In the late 1800s and early 1900s, people would travel for miles to visit "Lithia Springs." These were natural springs where the water was naturally high in lithium and magnesium. High-society figures and even US Presidents would soak in and drink this water to "cure the blues" and settle their nerves.
In fact, one of the most famous sodas in the world, 7 Up, was originally called "Bib-Label Lithiated Lemon-Lime Soda." It contained lithium citrate and was marketed as a mood-boosting tonic and a hangover cure. The FDA eventually made them take it out in 1948, but the legacy of lithium as a "feel-good" mineral remained in our collective memory.
Over time, we moved away from these natural mineral sources. Our tap water is filtered to remove almost everything, and our soil is depleted. We’ve essentially "cleaned" the mood-stabilizing minerals right out of our lives. By using magnesium and lithium bath salts today, we’re really just reclaiming a natural wellness practice that our ancestors took for granted. We’re going back to the springs, but in our own bathrooms.
One of the biggest questions we get is: "Does soaking in minerals actually do anything?" The answer lies in transdermal absorption. Our skin is our largest organ, and it’s surprisingly good at letting certain nutrients in while keeping the bad stuff out.
When we take magnesium supplements orally, we have to deal with the "laxative effect." The gut can only handle so much magnesium at once before it decides to... clear everything out. This means we often can't take enough magnesium orally to truly impact our stress levels without getting a stomach ache.
By soaking, we bypass the digestive system entirely. The minerals move through the skin barrier and into the capillaries just beneath the surface. This allows for a higher concentration of minerals to enter our system over a 15-to-30-minute period. It’s a gentle, steady way to replenish what we’ve lost.
While Epsom salt (magnesium sulfate) is the most common bath salt, it’s actually less effective for nutrient replenishment. Magnesium chloride has a unique molecular structure that makes it more soluble and easier for our skin to "grab." It stays in a liquid state longer on the skin, giving our bodies more time to absorb it. If we’re gonna spend the time to take a bath, we might as well use the version that works the hardest.
We don't need a medical degree to understand why lithium feels good. In simple terms, lithium is neuroprotective. It helps our brain cells (neurons) stay healthy and resilient against the damage caused by chronic stress and cortisol.
When we’re chronically stressed, our brains can get a little "inflamed" and disorganized. Lithium orotate helps regulate the neurotransmitters that keep our mood stable. It helps boost the activity of chemical messengers that make us feel calm while dampening the ones that make us feel agitated or hopeless.
In a bath soak, the lithium orotate is absorbed in trace amounts. It isn't about a massive hit to the system; it’s about a subtle, consistent "nudge" toward balance. Many of us find that after a soak with lithium, the "mental chatter" slows down, and the things that felt like a huge deal an hour ago suddenly feel manageable.
Taking a magnesium and lithium bath isn't like taking a bubble bath with a rubber ducky. It’s a treatment. Here’s how it usually goes down for us:
When we started Flewd, we knew that people were tired of "self-care" that was just about smelling like a candle. We wanted to create something that actually addressed the biology of a bad mood. That’s why we developed the Sads Smashing Anti-Stress Bath Treatment.
We didn't just stop at magnesium and lithium. We looked at what else our bodies lose when we’re feeling weighed down. We added:
We wanted to create a "liquid hug" for the nervous system. Our Sads Smashing formula is designed for those days when you feel like you're walking through molasses. It’s 99% natural, vegan, and biodegradable, because the last thing we need when we’re stressed is to worry about toxic chemicals in our tub.
It’s important to talk about the "L-word" responsibly. Because lithium is used as a prescription medication at very high doses, some people get nervous when they see it in a wellness product. However, the difference between prescription lithium carbonate and the lithium orotate found in bath salts is like the difference between a fire hose and a misting fan.
Trace-mineral lithium is something we naturally consume in small amounts every day. Using it in a bath soak is intended for general wellness and mood support for people dealing with everyday stress. It is not a treatment for clinical depression or bipolar disorder, and if we are managing a diagnosed mental health condition or taking prescription medications, we should always have a chat with our healthcare professional before adding new supplements or mineral treatments to our routine.
For most of us, these soaks are just a way to put back what the modern world has taken out. It’s about resilience, not "curing" anything. We’re giving our bodies the building blocks they need to handle the next difficult email or the next busy Monday.
Stress isn't a one-time event; it’s a constant pressure. That’s why we advocate for a routine. The first time we use magnesium and lithium bath salts, we’ll probably feel a nice "reset." But the real magic happens when we do it regularly.
When we maintain high levels of magnesium and trace minerals in our system, our "stress threshold" actually goes up. We don't get as rattled by the little things. Our sleep quality improves, which gives our brains more time to repair. Our muscles don't hold onto as much tension, which means we aren't walking around with our shoulders up to our ears.
We like to think of it as "stress insurance." By soaking a few times a week, we’re building up a buffer. We’re ensuring that when the "lions" of modern life show up, we have the mineral reserves to deal with them without falling apart.
While magnesium and lithium are a powerhouse for "the sads," different types of stress require different nutrient blends. At Flewd Stresscare, we’ve mapped out several "stress profiles" to help us choose the right soak:
The goal is to listen to our bodies. Sometimes we’re anxious; sometimes we’re just heavy. By choosing a soak that matches our specific symptom, we’re being much more intentional about our recovery.
We can't talk about wellness without talking about the planet. A lot of traditional bath products are loaded with microplastics, synthetic dyes, and "fragrance" (which is often just a fancy word for a cocktail of chemicals). When we drain that tub, those chemicals end up in our water systems.
We believe that stress relief shouldn't come at the cost of the environment. Our formulas are biodegradable, and our packaging is 100% PCR (post-consumer recycled). We use natural scents and minerals that come from the earth and can safely return to the earth. It’s one less thing for us to be stressed about while we’re trying to relax.
We know what we’re all thinking: "I don't have 30 minutes for a bath." We’re busy. We have lists. We have people depending on us. But here’s the truth—we’re gonna spend that 30 minutes anyway. We’re either going to spend it doom-scrolling on our phones, staring blankly at the TV, or feeling frustrated because we can't focus.
Investing 15 to 30 minutes in a mineral soak isn't "wasting time." It’s "buying time." When we come out of that bath feeling replenished and clear-headed, we’re actually more productive and present for the rest of our day. We’re better parents, better partners, and better humans when we aren't running on an empty mineral tank.
If we can’t do a full bath, even a foot soak can do wonders. The skin on our feet is highly absorbent, and it’s a looooong way from being a "waste of time."
Key Takeaway: Modern life depletes our mineral stores. Magnesium and lithium bath salts are a science-backed, historical, and incredibly efficient way to put those minerals back, helping us find balance in an unbalanced world.
The connection between our mineral levels and our moods is one of the most overlooked aspects of wellness. We try to think our way out of stress, or talk our way out of it, but sometimes we just need to soak our way out of it. By combining the muscle-relaxing power of magnesium chloride with the mood-stabilizing properties of lithium orotate, we’re giving our bodies a fighting chance against the "heavy" feelings of burnout.
It isn't about being perfect or never feeling stressed again. It’s about having the right tools to navigate the stress when it happens. Whether we’re using the Sads Smashing Soak or just learning more about how our bodies work, we’re taking an active role in our own stresscare.
If you’re feeling like the world is a bit too much lately, maybe it’s time to stop fighting it and start soaking it. At Flewd Stresscare, we’re here to help you get your spark back, one bath at a time.
Most people can enjoy these soaks safely, as they contain trace minerals intended for general wellness. However, if we are pregnant, nursing, have kidney issues, or are taking prescription medications (especially for mood disorders), we should always check with our doctor first.
Epsom salts are magnesium sulfate, which is less bioavailable than the magnesium chloride hexahydrate we use. Our soaks also include targeted nutrients like lithium orotate, vitamins, and nootropics, making them a functional treatment rather than just a simple bath salt.
Many of us report a sense of "mellowing out" or a lifting of mental heaviness within 15 to 20 minutes of soaking. Because the lithium is in a micro-dose form, the effect is subtle and calming rather than overwhelming or pharmaceutical-feeling.
We can certainly use them daily if we’re going through a particularly stressful time. However, for most of us, using them 2–3 times a week is enough to maintain our mineral levels and keep our stress threshold high.
