After 50, Your Body Steals Magnesium From Bones, Says Neuroscientist

<span>Magnesium</span> has become one of the most talked-about nutrients in the supplement space, especially among people looking to improve sleep, reduce stress, and support brain health. While experts consistently stress that magnesium-rich foods should be the first line of defense, supplements are often recommended when dietary intake falls short, provided they are taken after consulting a doctor.

Magnesium plays a critical role in brain function and overall health. It is involved in more than 300 enzymatic processes in the body, influencing everything from nerve signalling and muscle function to bone strength and sleep regulation. But not all magnesium supplements are the same, and choosing the wrong form could mean wasting money or dealing with unwanted side effects.

In an Instagram video published on February 2, neuroscientist Robert WB Love, who focuses on brain health and Alzheimer’s disease prevention, explained the differences between commonly available forms of magnesium. He also stressed why women above 50, in particular, should take magnesium intake seriously.

<h2>Why magnesium matters, especially for women over 50</h2>

According to Love, magnesium is essential for maintaining a healthy brain and body. He warned that when the body does not get enough magnesium through food or supplements, it compensates by pulling magnesium from the bones.

“Women over 50, listen up,” he said in the video. “If you don’t eat enough magnesium-rich foods or take a magnesium supplement to get the right amount, your body will literally steal magnesium from your bones to use in vital processes throughout the body.”

This, he explained, is why consistent magnesium intake is not just important for brain health but also for protecting bone strength as women age. Ensuring adequate magnesium through diet and supplementation can help support both cognitive function and skeletal health.

<h2>Magnesium citrate: Common but not ideal</h2>

Magnesium citrate is one of the most widely available forms, largely because it is inexpensive. However, Love described it as a low-quality option for brain health.

“It’s hard to absorb and can upset your stomach,” he explained, adding that many people experience digestive discomfort after taking it. Because of its poor absorption, magnesium citrate may not deliver meaningful benefits to the brain, making it a less effective choice overall.

<h2>Magnesium glycinate: Gentle and effective</h2>

Magnesium glycinate, according to the neuroscientist, is one of the better options available. It is well absorbed, gentle on the stomach, and beneficial for the brain and the rest of the body.

He also highlighted its positive impact on sleep and stress levels. Many people report sleeping better when they take magnesium glycinate before bedtime, making it a popular choice for those struggling with restlessness or anxiety.

<h2>Magnesium threonate: Best for the brain</h2>

Magnesium threonate stands out because of its ability to cross the blood-brain barrier. Love explained that this allows it to directly enter the brain, making it the most potent form for cognitive health.

However, it is more expensive and harder to find than other forms. Despite this, he noted that both magnesium threonate and magnesium glycinate are excellent options for brain support.

<h2>Magnesium taurate: The underrated option</h2>

Love also pointed to magnesium taurate, a form that does not get much attention. According to him, it is particularly beneficial for heart health.

“What’s good for your heart is good for your brain,” he emphasised, suggesting that magnesium taurate may offer indirect brain benefits by supporting cardiovascular function.
