Understanding the hype for a dose of magnesium

Touted as a cure for stress and sleep, magnesium has become a wellness obsession. Mint explores the science behind the noise

In the past few years, magnesium has evolved from a humble mineral into a wellness industry sensation. On TikTok, influencers tout its sleep-enhancing properties. High-end supplements—some priced at over ₹4,000 a bottle—promise everything from improved mood to faster metabolism. Beauty brands infuse it into bath salts and face creams, claiming it can soothe stress and rejuvenate skin. But how much of this is rooted in science, and how much is just savvy marketing?

Role of Magnesium

Magnesium is more than just a trendy supplement—it is a fundamental mineral involved in over 300 biochemical processes in the body. "It regulates muscle contractions, nerve function, and energy production," says Tanya Khanna, nutritionist and yoga trainer at Alyve Health, Dehradun. "It also plays a role in stress management, with some studies suggesting it helps regulate cortisol, the body's primary stress hormone." But does taking extra magnesium make a measurable difference? That depends.

For stress and anxiety: Research indicates that magnesium may help lower cortisol levels and promote relaxation—particularly in individuals who are deficient. But for those already meeting their daily magnesium needs, the effects are likely negligible.

For sleep: Magnesium supports melatonin production and helps relax muscles, which can aid sleep, especially in people with deficiencies. However, it is no substitute for good sleep hygiene.

For skin health: While some wellness brands claim magnesium improves skin, scientific evidence remains scarce. Its role in reducing stress-related breakouts may be its only real connection to skincare.

While magnesium is undeniably essential, its rise to wellness superstardom demands a closer look.
