Does this sound like you?
Your energy
You wake up tired, hit a wall by 2 pm, and run the rest of the day on coffee and willpower.
Your hair
Your ponytail is getting thinner, and there’s more hair in the shower drain than there used to be.
Your nights
Your legs won’t stop moving, so you lie awake even when you’re exhausted.
Your stairs
You get winded halfway up, and your heart races for no reason.
Your hands and feet
Always cold, even when everyone else is comfortable.
Your cycle
Your periods are heavier than they used to be, and you were told that’s “just how it is.”
Your brain
Foggy, forgetful, low, and you can’t remember the last time you felt like you.
Your gut
You tried iron once, got so backed up you quit, and you’re still dreaming of perfect poops.
Your labs
Your doctor said everything looks “normal,” and you left with more questions than answers.
If you nodded along, there’s a good chance nobody has looked at your iron the right way yet.
Most labs only flag ferritin as low when it drops below about 15. But many women start feeling the drain when it’s under 50. You can be told everything looks fine while your iron stores are running on fumes.
Energized. Glowing. Sharp. Magnetic. Feral.
That’s still you. Low iron is one of the most common, most missed, and most fixable reasons women lose their sparkle.

Hi, I’m Elena
When I was diagnosed with Graves’ disease, I was handed a prescription and not much else. Over the next few years, between Thyroid Eye Disease, gut infections, and months of exhaustion, I kept hearing that my labs were “in range.” It wasn’t until I dug deeper that I found what was really going on, and low iron was part of it.
Rebuilding my iron, gently and consistently, alongside supporting my gut, was part of what brought my energy back. Now I help women do the same, and I put everything I know about iron into this guide so you can find your answers sooner.
