don’t be the weirdo that drinks your bathwater seriously you don’t need to in this video I want to explain something about Epsom salt baths we’ll talk about if you can take an Epsom salt bath and actually absorb magnesium through your skin pretty interesting stuff but first and foremost we have to remember that Epsom salt is not really a salt it’s actually magnesium sulfate what that means is it’s magnesium sulfate and water molecules all together but what we really want to determine is can that magnesium sulfate pass through your skin get into your bloodstream and potentially replenish depleted or deprived magnesium stores I’m going to reference some studies that lead us in some pretty powerful directions although nothing is truly conclusive okay the first thing I want to look at is a study that was done in vitro okay this study was done in a petri dish that’s what in-vitro means it means that it wasn’t done in an actual live trial it was done in a lab however still lots of good science that can come from that what this study looked at was if anyons and cations can pass through skin molecules or skin tissue to actually potentially allow the absorption of nutrients well this study did find that anyons and cations which are basically just negatively charged ions and positive charged ions can indeed pass through skin tissue so that was phase one we wanted to look at how magnesium can pass through but now we actually want to look at if magnesium levels can be restored in the blood if you can go one step further well the good news is there’s a study that looked at that the bad news is is it wasn’t a public study it wasn’t peer-reviewed and there was no control group so unfortunately we can’t lean on it entirely but we can look at it for at least some anecdotal evidence that it may very well be something that you can do to help restore magnesium levels maybe even it’s just temporarily so this study was done of the University of Birmingham what they looked at was when they took 19 participants that took baths with Epsom salt for seven days they wanted to see what their actual serum levels of magnesium were after that point in time well 17 of the 19 participants showed elevated levels of serum magnesium after a few days of taking the bath two of them did but those two still showed an increase in urine magnesium levels what does this mean it means that their levels of magnesium might have already been high enough in their blood to where their body just excreted it out but you’ve seen some of my videos before and you’ve seen me talking about the fact that serum magnesium levels may not be the most important thing it’s really the mag RBC that matters what’s actually absorbed and what’s actually in the red blood cell or in the bone or soft tissue so although those serum levels do tell us that magnesium was potentially absorbed we don’t know if the body is actually utilizing it really the only true solid way to get magnesium that we’re going to utilize is to be actually getting it from the diet or getting it from a supplement that kind of llao us to absorb it and sustain release fashion but what are absent salt baths good for well they definitely help you relax your muscles although I have to say a lot of that is anecdotal evidence as well you see a lot of studies are starting to show that maybe the Epsom salt baths are really just helpful because you’re taking a warm bath and potentially the absorption of the magnesium through the bath may actually come from the inhalation of the magnesium rather than the absorption through the skin so we really don’t know the answer all we do know is that magnesium sulfate is a quick absorbing magnesium if it’s used intravenously or if it’s consumed that’s why a lot of times hospitals will use it they’ll even throw it in kind of an IV form to actually induce a laxative effect or get a massive increase of magnesium whenever possible but just for that reason you may not want to rely on magnesium sulfate or drinking your bath water as a form of getting your magnesium then because I hate to break it to you you’re going to be running the bathroom almost invariably so that’s why it’s extremely important to get your magnesium from food or to make sure that you’re monitoring your magnesium and monitoring your own symptoms to see if your cramping to see if you’re feeling differences in your mood to see if you really need more magnesium but as always something want to have a balance of you want to have a sustained amount of healthy minerals coming into your body keeping your body in balance and keeping that polarization in check now that I’ve talked about so many other videos what I’m so passionate about is the fact that magnesium truly might end up being at the core of what we need to do to become healthier human for a long period of time ahead of us as always keep it locked in here on these videos and I’ll see you in the next one

Epsom salt is composed of magnesium, sulfate and water molecules. The most common suggested use is for the relief of sore muscle pain.
● No research to back this up for epsom salt specifically
● Warm water does help relax stiff muscles and joints
Baths are known to relax people, and thus an epsom salt bath can help those who are stressed. Another less discussed benefit that was demonstrated has been demonstrated is the possible absorption of magnesium and sulfate through the skin. *Not many studies out there to confirm this, however: A 2002 study looked at the ability of certain anions (negatively charged ions) and cations (positively charged ions) to be absorbed through skin in vitro and found that both magnesium and sulfate were able to penetrate skin.
There was one study conducted that examined this and found these compounds to be absorbed – if you read online you will find this study discusses a lot
● Study was not published
● Study was not peer reviewed
● There was no control group
This study was conducted at the University of Birmingham. 19 participants bathed in a bath with epsom salts for one week and had serum and urine sulfate and magnesium levels measured before and after the week of magnesium sulfate baths. Following 7 days of baths 17 participants experienced a raise in serum magnesium levels. The 2 participants that did not experience a serum raise in magnesium levels did experience an increase in urine magnesium levels. The study suggested this could be due to magnesium being absorbed and excreted due to serum magnesium levels already being sufficient. Similar results were found with regard to sulfate, with both serum and urine sulfate levels higher following 7 days of baths.
Mechanism was not studied – if it does increase these levels, it could be through skin, inhalation, etc.
*We want to be cautious due to limits of this study however, the previously noted in vitro study did find that these compounds could penetrate skin.
*More studies are needed before we should count on this for magnesium.
Unfortunately there is a lack of studies regarding magnesium sulfate and ability to be absorbed during baths. There is no downside in taking epsom salt baths – at worst, they can offer stress relief, but at best we may be boosting our magnesium and sulfate levels, reducing stress and helping sore muscles.
Magnesium sulfate is also used internally and intravenously in medicine:
● Irregular heartbeat
● Low magnesium levels
