Magnesium, once a humble mineral known mostly to nutritionists and chemists, has quickly become the darling of the wellness world. With supplement aisles overflowing and social media abuzz, the question on everyone’s mind seems to be: can magnesium really deliver on its promises of better sleep, improved digestion, and a calmer mind?
The numbers tell a story of surging demand. According to BBC News, the global magnesium supplement market is now worth nearly £3 billion and is projected to almost double over the next decade. In a small factory tucked away in the Yorkshire Dales, Lonsdale Health’s pill-pressing machines churn out magnesium citrate tablets at a dizzying pace, destined for customers not only across the UK but as far afield as Australia, parts of Asia, Kuwait, and Iraq. “We are sending our supplies all over the world,” said Andrew Goring, managing director at Lonsdale Health. “Around the UK, obviously, but also to Australia, parts of Asia, Kuwait, Iraq. It’s one of our biggest sellers and the market just keeps growing.”
But what’s fueling this magnesium mania? Goring points to the digital age, where health influencers and clever marketing campaigns have catapulted magnesium into the mainstream. “Influencers, social media—that’s what’s pushing it,” he explained over the din of machinery. “We’ve known about magnesium and its benefits for years and now, finally, it’s mainstream.”
Magnesium’s resume is certainly impressive. As BBC News reports, the mineral is involved in over 300 different bodily processes. It’s crucial for brain and mood support, helps nerves send messages, and aids in building brain cell membranes. It also plays a key role in balancing blood sugar, regulating blood pressure, and maintaining the rhythm of our heartbeat by moving calcium and potassium in and out of cells. The recommended daily intake is 270mg for women and 300mg for men, with the body storing about 25g—mostly in bones and tissues.
Yet, as dietitian Kirsten Jackson points out, the popularity of supplements doesn’t necessarily mean everyone needs them. “Clever marketing schemes,” she said, “magnesium is involved in areas people are willing to invest in: their sleep, digestion, mental health.” She cautions, however, that supplements only help if you’re actually deficient—and deficiency is hard to detect, since most magnesium is stored where it can’t be easily measured.
Nonetheless, personal stories abound. Take Katie Curran, a communications specialist who struggled with sleepless nights and racing thoughts. After two weeks of taking 270mg of magnesium glycinate daily, Katie noticed a marked improvement. “My sleep definitely improved, I had more energy. I became more active. Other things changed in my life, so I can’t put it down to just one thing, but I think the magnesium supplements were an important part of the puzzle,” she shared with BBC News.
Social media is flooded with similar testimonials, often tagged with “commission paid”—a nod to the commercial interests at play. Magnesium is now sold in a dizzying array of blends: mixed with L-threonate or glycinate for brain health and sleep, with chloride for muscle tension and pre-menstrual cramps, and with citrate or oxide for digestion and constipation. But do these combinations work for most people?
Nutritionist Kristen Stavridis urges caution. “The problem is there is not enough strong evidence to show the majority of these different magnesium supplements have a positive effect on the healthy population,” she told BBC News. Even if benefits exist, she adds, they’re likely limited to those who are genuinely deficient. “Many of us are not getting enough magnesium,” Stavridis admitted, noting that around 10% of men and 20% of women fall short of recommended intake. “But just taking a supplement is not the answer.”
She suggests starting with diet: seeds, nuts, whole-grain breads, greens, and fruit are all rich in magnesium. Jackson agrees, warning that if you don’t regularly eat foods like these, you’re likely missing out on other vital nutrients too. “One magnesium supplement is not going to sort all that,” she cautioned.
There’s also the risk of overdoing it. For healthy individuals, the body can usually flush out excess magnesium, but too much can cause diarrhea, vomiting, and nausea. For those with kidney disease, the stakes are higher: excess magnesium can lead to hypermagnesemia, a potentially life-threatening condition marked by paralysis or coma.
Despite these warnings, the supplement industry continues to innovate. On October 24, 2025, GONBERY, a health and wellness brand based in Delaware, announced the launch of its Magnesium Complex 7-in-1 supplement on Amazon.com. According to a press release published on openPR, each serving delivers a robust 350mg of elemental magnesium, covering over 83% of the daily recommended value. The formula features a triple-action blend: 50% magnesium bisglycinate for gentle absorption and relaxation, 30% magnesium citrate for bioavailability, and 20% magnesium malate to support energy production.
But GONBERY’s offering goes further, bundling 150mg of Ashwagandha Extract and 180mg of L-Theanine—adaptogens known for their calming effects—along with 1000mcg of Vitamin B6 and 10mg of Zinc, both essential co-factors in magnesium metabolism. “Our goal was to create a superior magnesium supplement that goes beyond the basics,” said Orion, founder of GONBERY. “We wanted a comprehensive formula that addresses the interconnectedness of stress, sleep, and nutrient deficiency.”
The supplement is designed for adults living fast-paced lives and seeking natural ways to manage stress, sleep, and muscle function. Each bottle contains 30 servings (60 capsules), with the recommended dose being two capsules per day, taken with food and a beverage. By making the product available on Amazon, GONBERY aims to reach a broader audience on their wellness journeys.
While the science behind multi-ingredient supplements is still evolving, there’s no denying the appeal of a product promising to tackle several issues at once. Yet, as both Jackson and Stavridis emphasize, supplements should never be a substitute for a balanced diet and healthy lifestyle. The best approach, they insist, is to start with food, not pills—and to remember that what works for one person might not work for another.
As the magnesium market continues its meteoric rise, consumers are left to navigate a landscape where hope, hype, and hard science often intermingle. One thing is certain: magnesium’s moment in the spotlight isn’t fading anytime soon.
