Magnesium is a mineral your body uses for muscle and nerve function, and it may help with some of the classic period villains: cramps, restless sleep and low mood. It is not a magic cure, and it will not fix everything, but for a lot of people it takes the edge off. Here is what it may do, and how to actually use it rather than just buy it and forget it.
Can magnesium help period cramps?
It may. Some people find that magnesium takes the edge off period cramps, though the evidence is still building and it is not the same for everyone. Think of it as one useful tool alongside heat and movement, not a stand-alone fix. If cramps are severe or stopping your day, that is worth a chat with your GP. More on natural period pain support.
How does magnesium affect sleep and mood?
Magnesium is involved in the systems that help your body wind down, so some people find it supports calmer sleep and a steadier mood, which is handy when your period brings the 2am wake-ups and the short fuse. Again, it is support, not a switch, but it is a gentle one to try
Spray or tablets: which is better?
Both have their place. A magnesium spray goes straight onto the skin over the area you want to support, like your lower belly or back, which makes it easy to use exactly when a cramp hits and avoids the tummy upset some people get from tablets. Tablets suit a daily top-up. Plenty of people use a spray on their period and don't overthink the rest.
How do you use magnesium spray?
Spritz it onto clean skin over your lower belly, lower back or legs and rub it in. A light tingle the first few times is normal. Use it when cramps land or as part of a wind-down before bed. Pair it with heat for the full effect. Follow the label for how much.
What are the signs you might be low on magnesium?
Things like muscle cramps, fatigue, poor sleep, low mood and headaches can all be linked to low magnesium, though they overlap with plenty of other causes including your cycle itself. If you're regularly wiped out, it is worth looking at the whole picture with a professional rather than self-diagnosing. More on the signs of low magnesium.
