Half Of Women With Heavy Periods Are Iron Deficient — And Their GP Never Tested Ferritin
The standard blood test misses the depletion. Here’s the iron form that rebuilds ferritin without wrecking your stomach.
The test you actually need is ferritin. And the treatment you actually need is not the ferrous sulfate that made you feel worse.

The test you need is ferritin. The number your GP calls “normal” is far below what functional-medicine considers optimal.

The right form is ferrous bisglycinate — comparable absorption to sulfate without the constipation. Paired with methylfolate, vitamin C and B12.
Half of women with heavy periods are iron-deficient. Their GP tested haemoglobin. Haemoglobin is the last thing to drop.
RESERVE puts these four in a daily deep-pomegranate-red gummy. Two gummies a day, ideally with a squeeze of lemon.
Week two the fatigue softens, week four the hair-in-drain reduces, week eight the ferritin retest lifts.
