At some point, my TikTok algorithm decided I might be magnesium deficient. What followed was classic TikTok behavior: an unrelenting feed practically pressuring me to buy one of its most buzzed-about supplements, Lemme. But as someone who's naturally stubborn and not easily swayed by supplement trends (especially when they involve shaking up my morning routine), I was skeptical. Do I — along with the rest of TikTok — really need magnesium supplements for optimal health? To get the facts and put my curiosity to rest, I turned to Jillian Kubala, MS, RD, a registered dietitian based in Westhampton, NY.
Let's start with the basics. "Magnesium is an essential mineral, meaning your body can't make it on its own, and you must obtain it through your diet or supplementation," Kubala explains. "It's needed for blood sugar and blood pressure regulation, muscle contraction, stress regulation, nerve function, DNA synthesis, and many other important processes, so it's important to take in magnesium-rich foods or supplements on a daily basis."
Here's where things get tricky: "Even though magnesium is found in many foods, such as beans and vegetables, many people don't take in enough magnesium to maintain optimal blood levels. Most people can benefit from a magnesium supplement, especially those who follow diets low in plant foods, those with high blood sugar and blood pressure levels, and people with high and/or anxiety stress levels."
As with all supplements, it's important to manage expectations; it's not a cure-all. "Though magnesium supplements have been shown to reduce stress and anxiety levels in certain populations, they're not a magic bullet when it comes to reducing stress or treating mental health conditions," Kubala adds. She also notes that magnesium is "generally considered safe and not associated with many adverse side effects," though consulting a medical provider is crucial to ensure it's the right choice for you.
Ahead, we've rounded up the seven best magnesium supplements to consider adding to your regimen in 2025, including an option hand-picked by Kubala, an editor-loved powder, a celeb-founded favorite, and more.

Best Magnesium Supplement on Amazon
Nature Made Magnesium 250 mg ($5, originally $12)
You can't beat the price of this popular magnesium supplement. Its star ingredient, magnesium oxide, is great for supporting nerve, heart, and bone health. Many reviewers swear by its added bonus: a little extra help with constipation.

Best Magnesium Drink Mix Powder
Natural Vitality Calm Drink Mix Powder ($17, originally $41)
The magic of this drink mix powder — evident from its tens of thousands of five-star reviews — is its use of magnesium citrate, a highly absorbable form of the mineral. When mixed with water, it creates a fizzy drink you can sip daily to tackle constipation (with a gentler laxative effect than the aforementioned magnesium oxide) and help address magnesium deficiencies that might be causing a variety of annoying symptoms like sleep troubles.

Best Dietician-Recommended Magnesium Supplement
Pure Encapsulations Magnesium (Glycinate) Supplement ($26)
This supplement recommendation comes straight from Kubala, and it also happens to be the number-one-selling magnesium supplement on Amazon. "I love Pure Encapsulations Magnesium Glycinate," she says. "It's a highly bioavailble [meaning highly absorbable] form of magnesium that's great for sleep, blood sugar and blood pressure management, and stress management."

Best Celebrity-Founded Magnesium Supplement
Lemme Sleep Gummies ($27, originally $30)
Kourtney Kardashian launched Lemme in 2022, and its easy-to-take gummy formulation — not to mention the cute packaging — are just two of the reasons it's gone viral. One of our editors tested Lemme Sleep, along with the brand's other supplements, for 30 days and noticed an improvement in her sleep quality. Worth noting: these gummies contain five mg of melatonin, 20 mg of magnesium, and 50 mg of L-theanine, an antioxidant that may help with relaxation. Read more about her experience testing the brand in her comprehensive Lemme supplement line review.
Editor Quote: "These are designed for people who have trouble falling asleep and those who inconsistently maintain uninterrupted sleep, and I would say I tend to fall into the latter category, typically awaking at least two times throughout the night to pee. Ever since taking them, I wake up once a night at most, and many reviewers agree that they also feel less drowsy in the morning." — Sarah Wasilak, associate content director, Shopping

Best Magnesium Supplement Drink
Recess Mood Magnesium & Adaptogen Drink ($38, originally $41)
The beverage brand Recess introduced its mood-boosting line in 2022, branching out from its signature CBD-infused drinks. As one of our editors described in a review, the line features magnesium L-threonate (a form of magnesium linked to improved cognitive function and mental clarity in a 2022 study) combined with L-theanine and "adaptogens that are intended to increase the production of 'feel-good' neurotransmitters like serotonin and dopamine." After sipping on one, she noticed a sense of calm, and she's not alone; many Amazon reviewers echo the same experience. Read more in our Recess Mood Magnesium & Adaptogen Drink review.
Editor Quote: "I understand that drinks like these may seem frustrating or silly to people, especially when there are so many other products out there that can alter your mood in a much more drastic way — inhibiting your senses and altering your mindset. But speaking as someone whose body does not physically allow them to escape the realm of sobriety, Recess offers a brief but welcome relief. A calmness that, at the very least, offers some comfort and gives me a way to participate in the uniquely social behavior that often comes with drinking. At the very least, I would encourage you to give Recess a try, and know that on the off chance it doesn't make you feel better, it definitely won't make you feel worse!" — Chandler Plante, assistant editor, Health and Fitness

Editor Quote: "Within an hour of drinking the solution, I can literally feel my body loosening up and my mind slowing down, providing me with a more relaxed state before going to bed. Unlike melatonin, I don't experience any symptoms of fatigue the next morning — if anything, I feel sharper and more well-rested." — Kyley Warren, assistant editor, Shopping
