You’re dragging yourself through the day. Coffee isn’t helping. Your motivation has disappeared and all you want is to crawl into bed with some chocolate and no responsibilities.
If this feels familiar in the week before your period, you’re definitely not alone.
Fatigue is one of the most common PMS symptoms, but it’s not just about hormones. Often, your iron and magnesium levels are playing a big role too.
Let’s unpack why.
Why Am I So Tired Before My Period?
Right before your period starts, your body goes through a wave of hormonal changes. Estrogen drops, progesterone peaks, and inflammation can rise. All of that can affect your sleep, energy levels, and overall mood.
But there’s something else going on too.
1. Iron Starts to Drop
Your body is getting ready to lose blood, and that means it’s also pulling from your iron stores. If your iron is already low (which is super common if you’re menstruating), this extra demand can leave you feeling totally wiped out.
2. Magnesium Gets Used Up
Magnesium plays a huge role in energy production, mood regulation, muscle relaxation and sleep quality. Right before your period, your magnesium levels can drop, making you feel even more tired, irritable, and out of balance.
So when your body is low in both iron and magnesium, it’s no surprise that your energy takes a hit.
