I had been diagnosed with
slight anemia decades ago. I never really did much about it. Now and then I'd take some multivitamin with iron. Since I have a hard time swallowing pills, I finally switched to chewable Flintstones Complete. But even then I was only taking them sporatically.
My periods have always been heavy. Several years ago they got worse with the cramping, accidents and utter exhaustion. I'd only remember to take more iron then.
I started perimenopause several months ago, and the past couple of months have been getting my period every two WEEKS!

The periods have been heavier and lasting longer.

The exhaustion has been extreme and the moodiness unbearable. I've also been having memory problems and sometimes have problems concentrating even on simple tasks. (I have a genius I.Q. so stuff like that shouldn't have been a problem normally.)
Only last week, I happened upon a Runners' forum where a thread was talking about Iron-deficiency anemia. OMG!!!

I had every one of the symptoms the various members listed, it was about
10 symptoms.

They said the symptoms of anemia creep up slowly, so you attribute it to other things.
One symptom was an intense craving and addiction for strong mints. I have been addicted to Altoids mints, like you wouldn't believe.

I not only have to have them, I have to
chew them.
Another symptom is heart arrhythmia (irregular or stopped heart beats) and hearing/feeling loud heart beats. This has only been happening recently. I might have a mitral valve prolapse, and originally figured it might finally be catching up with me.
I knew I should go to a Dr. or my GYN and finally get some tests run. But when I read that runners' forum, I almost ran right to the 24hr drugstore to get iron pills right then at 3am.
I headed to the health food store the next morning and they recommended
Nature's Plus Hema-Plex to me. It's all natural & vegetarian. The sales clerk said it does not cause stomach or constipation problems as other iron supplements do. It has 85 mg of iron (472% RDA.) plus extra Vitamins B, C, folate, etc.

I have been taking it for the past 5 days and already I feel quite a difference. I take 1/2 a tablet morning and the other half at night with my meals. I have had no stomach problems, making sure I have one on a full stomach. The other meals, I chew a Gummy Vites multivitamin with Vit D. (It has no iron.) I'm religious about taking all of these now.
My energy level is up. I actually have energy to clean the house & tacke all the clutter that accumulated from the exhaustion.

The memory & concentration problems are pretty much gone. The Altoids craving is gone today. And no more insane irritablilty!!!

I'm sure many a DISer who I snapped at in recents months must be relieved over that one.

I sincerely apologise to anyone I did snap at.
I'm pretty sure it's not a placebo effect. There are way too many symptoms that have been changed.

Perimenopause has been making me bleed out nearly every day and moved me from being slightly anemic to majorly anemic.

Even the dark circles under my eyes are lessened. And the sun/age spots on my face seem to be disappearing. There's much more color to my skin tone now.
