Why it matters, why levels run low, and how to manage it well

You often feel tight and tired at the same time. Your muscles never seem to fully let go, no matter how much you stretch. You fall into bed exhausted at night, but your mind keeps spinning. If this sounds familiar, you have probably seen magnesium mentioned as a possible help.

There is a reason for that.

Magnesium is one of the key nutrients your body needs to help your muscles relax and your nervous system settle. It also plays a quiet but essential role in how your body produces and uses energy. When your magnesium levels are low, you rarely feel one dramatic crash. Instead, you might notice several small changes that build over time: your muscles stay tense, your sleep feels less restful, and your body takes longer to recover after exertion.

If that sounds familiar, magnesium is worth a closer look. It is not a magic cure, but it is a piece of the foundation.

What magnesium actually does in your body

Magnesium is involved in hundreds of processes. A few matter most in everyday life: calming your nervous system, relaxing your muscles, producing energy, and moderating sensory input. Your body runs these systems constantly, and magnesium is part of the background chemistry that keeps them running smoothly.

When your body does not have enough magnesium available, no single function fails completely. Instead, multiple systems become less efficient. Your nervous system, muscles, and energy production still work, but they work harder than they should.

Your nervous system needs magnesium to downshift

Throughout the day, your nervous system cycles between activation and recovery. Activation means getting things done and responding to stress. Recovery means resting, digesting, and sleeping. Magnesium is one of the main nutrients that supports the recovery side of that cycle.

When magnesium runs low, many people notice it takes longer to shift into a settled state. You might find it hard to truly relax in the evening, or you might feel mentally alert even when your body is physically tired. Stress and sensory input can feel more intense, and you may stay "switched on" long after the busy part of the day is over.

None of this means magnesium is a sedative, since it does not force you to sleep. But it helps create the conditions that make downshifting easier. Without enough of it, your nervous system has to work harder to find calm.

Muscles need magnesium to let go

Your muscles are constantly alternating between contraction and release. Magnesium is essential for the release phase of that cycle. When it is in short supply, muscles can get stuck in a slightly more tensed state. This is not usually dramatic. It is more like a low‑grade tightness that never fully goes away.

Over time, this low‑grade tightness might show up in a few ways.

You have ongoing muscle tension that resists stretching.
You get occasional cramping or twitching.
You never feel fully relaxed, even when lying down.

In hypermobility, this matters even more. Your muscles are already working overtime to stabilize joints that move too much. When you add low magnesium into that picture, the tightness and fatigue that hypermobile bodies already deal with can get noticeably worse. It is not that magnesium deficiency causes hypermobility symptoms. But it can amplify them.

Energy and recovery take a hit

Magnesium is involved in the production and function of ATP, which is your body's main energy currency. When your magnesium status is not optimal, you might notice the following patterns:

Recovery takes longer after exertion.
Busy days leave you dragging for longer than they used to.
Your fatigue feels out of proportion to what you actually did.

The pattern here is not that you cannot produce energy at all. It is that bouncing back, meaning your recovery efficiency, slows down. When you are already managing a body that tires easily, that slowdown can be the difference between a functional week and a crash.

Sensory sensitivity and pain can ramp up

Magnesium helps regulate how excitable your nerve cells are. When levels are low, your nervous system becomes easier to trigger. That means signals from your body, including pain, tension, and internal sensations, can feel more intense than they otherwise would.

In hypermobility, where your joints are already sending a lot of mechanical input to your brain, this lowered threshold can show up as:

Feeling small discomforts more acutely.
Taking longer to settle after physical strain.
Experiencing more day‑to‑day variability in how intense sensations feel.

Pain is never simple as it is shaped by sleep, stress, load, and past sensitization. But magnesium sits inside that bigger picture so when it is missing, the picture gets messier.

Why magnesium levels often run low

Three main factors control your magnesium balance: intake (what you eat), absorption (how much your gut actually takes up), and demand (what your body uses up).

In hypermobility, all three can go wrong:

Intake is often lower than it should be for two reasons. First, magnesium‑rich foods like leafy greens, nuts, seeds, legumes, and whole grains are not always front and center in a modern diet. Second, even when you eat these foods, modern farming practices have reduced the magnesium content of soil, so the food itself contains less than it used to.

Absorption is a common problem in hypermobility. Research has shown that gastrointestinal symptoms are highly prevalent in people with hypermobility syndromes, and those symptoms can directly interfere with the absorption of key nutrients. Even with a good diet, if your gut is not absorbing well, the magnesium never makes it into your system.

Demand can be chronically elevated due to stress, poor sleep, pain, and the simple fact that a hypermobile body works harder to hold itself together. More demand means you need more intake just to stay even.

Medications that can affect magnesium

Several commonly used drugs can lower magnesium levels over time. The main ones to be aware of include:

Proton pump inhibitors, such as omeprazole and esomeprazole, are often used for reflux. They reduce stomach acid, which in turn can reduce magnesium absorption.
Diuretics, sometimes used for blood pressure or POTS, increase magnesium loss through urine.
Fludrocortisone, which is used in some POTS protocols, shifts fluid and electrolyte balance. That can indirectly affect magnesium status.
Stimulant medications for ADHD, like methylphenidate or amphetamines, do not directly deplete magnesium in a simple way. However, they increase nervous system activation, suppress appetite, and disrupt sleep. All of these raise magnesium demand, and over time that can contribute to lower levels.

None of this means you should stop a medication. It just means that if you are on one of these medications and you have hypermobility‑related symptoms, magnesium is worth a closer look. You might want to have a conversation with your clinician about monitoring or supplementation.

How low magnesium shows up in daily life

There is no single symptom that means "low magnesium." Blood tests are not always reliable for tissue levels, so patterns matter more than any one sign.

Here are some commonly reported experiences.

Your muscles feel tense and do not fully ease, even with stretching.
You feel restless in the evening, like you need to move but you are not sure why.
Your sleep is lighter or more disrupted than it should be.
You get headaches more often than usual (not always, but often enough to mention).
You feel more reactive to stress than usual.
Your fatigue seems out of proportion to what you did.

These overlap with many other conditions, so magnesium is best viewed as one possible contributor, not the whole explanation. But if several of these sound familiar, it is worth experimenting with it to see if you experience any symptoms relief.

If you are hypermobile and also neurodivergent

If you are hypermobile and also identify as neurodivergent (ADHD, autism, or both), you may have noticed that your system feels especially load‑heavy. Sensory input, attention shifts, and sleep differences can all increase your body's daily demand for magnesium.

There is growing research on magnesium and neurodivergence, but this topic deserves its own space. We wrote a separate post on magnesium for ADHD and autism, with a focus on how it applies to hypermobile bodies as well. You will be able to find the link next week. [link to future post]

Which magnesium supplement should you take?

All magnesium supplements give you the same mineral, but the form affects absorption, digestion, and tolerance. Here is a practical guide:

Magnesium glycinate (bisglycinate) is attached to glycine, an amino acid with mild calming effects. It is well absorbed and generally gentle on the stomach. For most people, this is the best starting point for nervous system support, muscle tension, and sleep.
Magnesium citrate is also well absorbed, but it pulls water into the intestines. That makes it useful if you are also dealing with constipation. The downside is that it can cause loose stools if you take too much.
Magnesium malate is attached to malic acid, which plays a role in energy production. Some people prefer this when fatigue and muscle pain are the main issues, but the evidence for a big difference is not strong.
Magnesium threonate is marketed for brain health because it may cross the blood‑brain barrier more effectively. The research is still early, and the claims often outrun the evidence.
Magnesium oxide is cheap and common, but it is poorly absorbed. It is more likely to give you a laxative effect than to actually improve your magnesium status.

There is no single best form for everyone. Start with glycinate if you are unsure, then pay attention to how you feel and how your digestive system responds. Additionally, do not trust marketing claims that promise highly targeted effects.

How much to take and how to take it

Most adults need about 300 to 400 milligrams of total magnesium per day from food and supplements combined. A typical supplement provides 100 to 200 milligrams of elemental magnesium per serving (Elemental magnesium means the actual amount of the mineral, not the total weight of the pill.)

Many people split their dose between morning and evening which helps for two reasons: First, it reduces the chance of loose stools or stomach upset. Second, it keeps a steadier level of magnesium in your system throughout the day, which may support your nervous system more consistently.

Start low and go slow. Too much at once, especially with citrate or oxide, will almost certainly cause digestive issues. If you have kidney disease, do not supplement magnesium without medical supervision.

Magnesium can also interfere with absorption of some antibiotics, like doxycycline or ciprofloxacin, so it is best to take them at least two hours apart.

Putting it all together

Magnesium is a small piece of a much larger puzzle, however, it sits in an important place.

If your system does not have the basic resources it needs to regulate, recover, and produce energy, then everything else, including movement therapy, strengthening, and lifestyle changes, becomes harder. In other words, your body ends up working against you instead of with you.

At Paromotion, we do not only look at how you move, but rather we look at the conditions that make better movement possible. Nutrition, nervous system regulation, and movement are not separate topics, as they are one integrated system.

Everything is connected. The more you support the whole system, the more each piece starts to work with you instead of against you.

If you have been trying to improve your movement but feel like your body is not fully supporting you, this is often where we start.

A note on the research

Most of what we know about magnesium and muscle function, sleep, anxiety, and energy production comes from research on the general population. Those studies are well established. For people with hypermobility specifically, there are no large clinical trials yet.

However, a 2021 study confirmed that gastrointestinal problems are very common in hypermobility syndromes, which directly affects magnesium absorption. The recommendations here combine general magnesium research with the 2021 finding on gastrointestinal symptoms and with consistent clinical experience in the hypermobility community.
