Can magnesium make you tired?

When it comes to discussing the effect of magnesium on our body, we all know that it plays a vital role in numerous biochemical reactions. But have you ever wondered if consuming too much magnesium can lead to fatigue? Well, let’s dive deep into this topic and find out.

What is Magnesium?

First things first: what exactly is magnesium? It is a mineral found abundantly in the Earth’s crust and essential for human health. Our bodies require magnesium for many functions like producing energy, maintaining healthy bones, regulating heartbeat and muscle function, managing blood sugar levels, and supporting digestion.

So now we understand how critical magnesium is for our overall well-being. However, when it comes to balancing its intake – whether through diet or supplements – some questions may arise. One such question relates to whether excess consumption of magnesium leads to tiredness or not.

How Much Magnesium Do We Need?

Before jumping into the possible effects of overconsumption of magnesium on our bodies’ energy levels let us first focus on understanding how much do we need daily:

  • The Recommended Dietary Allowance (RDA) varies by age and gender:

  • For Adult males: 400-420 mg/day

  • For Adult females: 310-360 mg/day

While there are no immediate adverse effects known from an overdose of dietary magnesium, excessive intake can cause digestive issues since your gut cannot absorb more than necessary – which could ultimately affect your immune system negatively.

Can Excess Magnesium Lead To Fatigue?

Now coming back to the main topic: Does consuming excessive amounts of magnesium make you feel worn out/exhausted/fatigued during day-to-day activities? Well technically speaking No… but also Yes!

Allow me to elaborate:

First Reason Why Your Body Might Feel Tired:

One possible reason why some people might be feeling tired after ingesting an excess of magnesium is that it could lead to diarrhea, which means your body would lose more fluids and electrolytes than necessary. Hence magnesium has a laxative effect (fun fact, excessive use of magnesium in supplements is used as a medicinal natural laxative!), this overconsumption could mean that you end up with lower hydration levels than what’s optimal for regular functioning body temperature regulation systems.

Second Reason Why Your Body Might Feel Tired:

Another scenario where too much magnesium can make you feel lethargic or sleepy relates to individuals who have naturally low blood pressure. See, by nature, magnesium has vasodilatory properties – meaning it relaxes the walls of your arteries and allows them to expand- increasing blood flow efficiency during physical activity or increased heart rates; yet decreasing heart performance at restful states. For those whose bodies lack strong adrenal glands pumping out ample amounts of catecholamines/norepinephrine just like caffeine brings us from drowsiness mode into alertness mode when blocking adenosine receptors located in our brains(dopamine), sometimes supplemental forms of magnesium may act as a mild sedative instead.

Can Magnesium Help With Fatigue?

Now comes the good part: while it is true that your body might feel worn out if one goes heavy on their daily dose requirement without regard for other factors such as individual age differences between males & females(variance due hormonal fluctuations)…

…it also happens so that moderate consumption coupled with light exercise prior made reports showcase improved metabolic response leading towards revitalized energy levels for users experiencing initial exhaustion symptoms!

Other notable benefits correlated with incorporating sufficient magnesium into one’s daily routine include the following but are not limited to:

  1. Muscle Relaxation
  2. Enhanced Digestion
  3. Better Sleep Quality

Besides oral supplementation options traced back centuries ago using epsom salt or other such methods. Therefore, these applications all suggest that magnesium may have the potential to combat fatigue symptoms and promote better energy levels!

How To Balance Your Magnesium Intake?

Now, as we understand that consuming moderate amounts of magnesium does not harm our body but can rather aid in reversing any possible fatigue-related symptoms; let’s discuss how one should balance their intake.

Natural Sources

To provide your regular magnesium dietary needs sourced naturally – make sure you incorporate the following foods into a wholesome balanced meal:

  • Spinach
  • Almonds
  • Dark Chocolate
  • Avocado
  • Bananas
  • Whole grains

However, if due to diet preferences/disorder issues if meeting precise needs becomes impossible – supplements could also suffice.


Supplements come in many forms such as capsules(gelatin-free included)/topical products/fizzy powder/tablets/effervescent drinks/even chewing gums! Hence ensuring larger accessibilities for users who want more potent sources than natural diets alone offer.


All in all, when it comes to discussions around popular health topics like “can magnesium make you tired?”, the answer is not binary since just like every human body is unique on its own— with differences ranging from age-gender-variances-nutrient-deficiencies-medical-pre-existing conditions/lack thereof — so too are things like recommended daily magnesium intake and supplement dosages. However Just know & be pragmatic of what works best for YOU while engaging an informed physician along with reputable data-backed publications online about different uses(including water speeds)!. By doing so—you’ll help yourself feel energized throughout each day knowing there are many ways possible towards achieving optimal wellness!
