What Chicago Residents Should Know

If you’ve been dealing with anxiety, you’ve probably come across the term magnesium while searching for ways to feel calmer. Magnesium is known for its calming effects, which is why it’s commonly found in many over-the-counter stress-relief supplements. In recent years, conversations about alternative approaches to managing anxiety have become more and more common online, and magnesium is often part of that discussion.

Naturally, this leads many people to ask the same question: Does magnesium help with anxiety? For some individuals, magnesium may help ease certain symptoms. However, it’s important to understand that supplements have limitations and are not a replacement for professional mental health care.

They’re also not a suitable replacement for actual medications. That being said, Magnesium can sometimes play a role in overall health and wellness, but it isn’t a standalone solution for treating anxiety.

When considering magnesium for anxiety, it’s helpful to understand how it works, what types are commonly used, and what potential risks to be aware of. Just as importantly, it’s essential to know when anxiety may require more comprehensive support from a qualified mental health professional.

If you’re in Chicago and want to learn more about magnesium for anxiety, keep reading. We’ll explore what the research says and where you can find expert anxiety care in the city if you need more support.

Key Takeaways:

Magnesium is a naturally occurring mineral and electrolyte. It is necessary for many processes in the body, such as nerve function, blood pressure, and blood sugar regulation.
While results can vary, some studies suggest that magnesium may provide some relief as a complementary treatment. This can be case-specific. People with low magnesium levels and mild anxiety symptoms are the most likely to benefit from it.
There are different kinds of magnesium supplements. Some are better for anxiety than others. Magnesium glycinate is usually the most recommended type of magnesium for anxiety.

What Is Magnesium?

Magnesium is an essential nutrient.[1] It’s a mineral and electrolyte necessary for many processes in the body. For example, regulating nerve function, blood pressure, and blood sugar. While many foods contain magnesium, such as fortified cereals, nuts, seeds, molasses, and leafy vegetables, a significant portion of people don’t get enough.

With that in mind, it’s quite common to take supplementary magnesium. Depending on the type, it can be used for different reasons. For example, constipation relief, sleep, and stress.

Magnesium for Anxiety

Many studies regarding magnesium for anxiety are small, inconclusive, or have mixed results. While research on the topic is limited, there are still some findings we can review to better understand magnesium's effect. For example, a meta-analysis found that, in 5 out of 7 studies, there were self-reported improvements in anxiety levels.

The outcomes of these studies suggest that supplementary magnesium may be useful for mild symptoms of anxiety and insomnia. Specifically, for those with low baseline levels.[2] More research is needed to confirm efficacy and establish important information on how to take magnesium for anxiety (such as recommended dosage).

The takeaway? Magnesium is not a primary treatment for anxiety disorders. That said, it might be somewhat helpful in some instances, especially if you are deficient in magnesium. Magnesium does not provide enough relief to address mild to severe anxiety symptoms and it's more suitable for certain people than it is for others.

Potential Side Effects and Safety Considerations

Since magnesium is naturally occurring, people often assume that there aren’t any risks. This is not true. As with any supplement, there are potential side effects and safety considerations. Most notably, these include:

Serious complications can occur for people with certain health conditions. In general, the body is able to filter out excess magnesium through the kidneys. But if you have kidney disease, your body may not be able to process it safely. Additionally, your doctor may need to monitor your magnesium levels closely to avoid toxic accumulation. Similarly, people with conditions like myasthenia gravis should speak to their doctor before starting magnesium or any type of supplement. Because magnesium affects nerve and muscle function, it can sometimes worsen certain symptoms if not used carefully.
Magnesium toxicity. While it’s pretty rare, you can overdose on magnesium.[3] This tends to happen either when people take too much or when their bodies cannot process it properly due to conditions like kidney disease. Nausea, muscle weakness, vomiting, and low blood pressure are common early symptoms of magnesium toxicity. To avoid it, talk to your doctor about the right dosage for you.
Medication interactions with magnesium. Some medications interact with magnesium. Certain medication interactions can be mitigated with proper timing. In other cases, people need to avoid magnesium products altogether due to the risk of medication interactions. For example, magnesium can reduce gabapentin levels by 20-40%.[4] So, those taking gabapentin are often advised to wait to take products containing magnesium at least two hours after their last dose.
Magnesium side effects. Magnesium can come with side effects. Most often, these include things like nausea, diarrhea, abdominal cramping, and fatigue. Sometimes, changing how you take magnesium can alleviate side effects (e.g., switching the type of magnesium you take or taking it at a different time of day).

For most people, taking magnesium is generally safe. If you take magnesium, make sure to tell your doctor or healthcare provider. That way, they can inform you of any risks or considerations that are relevant to your personal health. They can also provide personalized guidance on how to take magnesium safely and identify issues like magnesium deficiency.

Magnesium Deficiency and Anxiety

Mild anxiety and nervousness are possible symptoms of magnesium deficiency.[5] If you are deficient in magnesium, your doctor may write you a prescription for magnesium. Alternatively, they can recommend an ideal OTC supplement.

In the case that your anxiety symptoms are due to a magnesium deficiency, getting your levels back up to normal should help address it. However, for those who have existing anxiety symptoms not due exclusively to magnesium deficiency, proper treatment for anxiety itself is vital.

How to Tell if You Have Magnesium Deficiency?

Anxiety and nervousness aren’t the only possible signs of magnesium deficiency. People with magnesium deficiency may also experience:

Irritability.
Tiredness.
Muscle cramps.
Muscle weakness.
Mild sleep disorders
Nausea and vomiting.
Gastrointestinal spasms.
Irregular heartbeat.
Headache.

The signs of magnesium deficiency can vary. Many people with a deficiency won’t have all of these symptoms. The only way to tell for sure whether you have a magnesium deficiency is to get tested. Usually, this involves a simple blood test.

Which Magnesium Is Best for Anxiety?

Magnesium glycinate is often suggested as the best option for anxiety. Why? There are a few reasons:

Calming effects. First and foremost, magnesium glycinate is a combination of magnesium and glycine (an amino acid that acts as a calming agent). For this reason alone, it’s the most recommended type of magnesium for anxiety.
High bioavailability. In addition to greater calming effects, magnesium glycinate is highly bioavailable. This means that it is exceptionally well absorbed by the body and brain. In turn, you’re more likely to get its effects.
Fewer gastrointestinal issues. Since magnesium glycinate is well absorbed (rather than rapidly excreted by the body), it’s associated with a lower likelihood of side effects such as diarrhea.

There's multiple types of magnesium supplements on the market. If your doctor recommends an over-the-counter magnesium supplement, double-check the bottle to make sure it’s the kind they suggest.

Can Magnesium Replace Anxiety Medication?

No. For some people, magnesium can be valuable as a supplementary tool. Despite this, magnesium cannot replace anxiety medication. They can both play a part in caring for your health, depending on your needs. Magnesium and anxiety medication simply have different roles.

Most anxiety medications build up in the body to create sustained relief from symptoms. This is the case with selective serotonin reuptake inhibitors (SSRIs) and selective norepinephrine reuptake inhibitors (SNRIs). These are some of the most frequently used medications for conditions like generalized anxiety disorder.

Other medications, like propranolol for anxiety, set in quickly. These are typically used for concerns like panic attacks and performance anxiety when people need something that works fast, even if they don’t necessarily need to take it daily.

A combination of medication and therapy is generally the first line of treatment for moderate to severe anxiety symptoms. This is also the case for mild anxiety symptoms not addressed in therapy alone. People who have, or believe they may have, an anxiety disorder should seek professional support.

Who May Benefit from Magnesium for Anxiety?

Keeping in mind that it plays its own unique role and can’t replace therapy or medication, you might wonder, who is most likely to benefit from magnesium for anxiety?

People with minor anxiety symptoms. Since magnesium is most likely to help with milder anxiety symptoms, it is usually best for those who have minor symptoms.
People who are deficient in magnesium. A lot of people have nutrient deficiencies or inadequacies. Sometimes, without knowing it. If you don’t get enough magnesium from the food you eat, or if your levels are low, supplementation may be recommended.
People with anxiety linked to sleep problems. Poor sleep (and lack of sleep) can make anxiety worse. Sadly, anxiety can also make you tired. If your anxiety is exacerbated by sleep problems, a doctor might recommend magnesium for sleep.

Magnesium can also support stress relief. So, people dealing with life stress who find magnesium helpful may benefit from taking it. It’s all about finding what works for your own personal needs.
