We’ve researched and tested dozens of clean magnesium supplements — these are our top nine picks made with only the best ingredients for maximum benefit.
Did you know a large subset of the US population doesn’t get their recommended daily intake of magnesium? This is especially concerning since our bodies need magnesium to function. It’s required to produce energy, metabolize glucose, regulate stress, fortify bone health, support sleep and digestive health, and more. If you’re curious about the many correlations between magnesium and better health outcomes, you might find this research helpful. 🔍
According to the NIH, the average woman between 19 – 51 years old should have up to 320 mg of magnesium a day, and pregnant adult women can have up to 360 mg daily. Ideally, a well-balanced diet (with lots of leafy greens, nuts, whole grains, and beans) would help meet our magnesium needs, though supplements can help bridge the gap.
What are the benefits of magnesium?
Magnesium is like the unsung hero of your body — it helps with muscle function, relaxation, and energy production while keeping your nerves, heart, and bones in top shape. It can reduce stress, improve sleep, and even ease muscle cramps (hello, post-workout recovery!). Plus, it supports a healthy metabolism and balanced blood sugar levels, which is great for overall wellness. If you struggle with headaches, anxiety, or trouble sleeping, adding more magnesium to your diet — or taking a supplement — might make a big difference.
The difference between magnesium citrate, glycinate, malate, oxide, and gluconate:
First, there are many forms of magnesium out there with various nuances, so here are the most common ones:
- Magnesium oxide (MO) is the most common form of magnesium supplements, but it’s not as bioavailable as other forms. Because of that, MO sometimes leads to diarrhea and other negative digestive issues. Similarly, magnesium gluconate, which has gluconic acid, can act as a laxative and get rid of constipation.
- Magnesium citrate is more bioavailable than MO with fewer side effects, so it’s beneficial for health issues like high blood sugar, high blood pressure, and anxiety.
- Magnesium glycinate is highly bioavailable, as you’ll see in many of the products listed below. It’s well-absorbed so there aren’t many negative side effects, and it’s particularly useful for reducing stress and supportive, restorative sleep.
- Magnesium malate combines magnesium, with malic acid, a naturally occurring compound, and it’s gentle on stomachs.
You’ll want to find the right form of magnesium based on your needs, and as always, we recommend speaking with your doctor before starting any supplements especially if you have preexisting conditions or take other medications. There is such a thing as too much magnesium, and those side effects can include diarrhea, vomiting, mood problems, muscle weakness and spasms, and low blood sugar.
