Iron is the one supplement to take only when you genuinely need it — and if a blood test or persistent fatigue points you there, this **Iron** tablet delivers 27mg of well-absorbed bisglycinate, squarely in the 15–45mg range used to rebuild low iron stores. At roughly 150% of the Daily Value, it's aimed at people actually running low: menstruating women, pregnancy, or a diagnosed deficiency.
The bisglycinate form absorbs far better than standard iron salts, with much less of the constipation and stomach upset iron causes. Pair it with vitamin C to boost uptake, and keep it away from calcium, coffee, and tea, which blunt absorption.
The key caveat is who should skip it: don't supplement iron "just in case." Without a documented deficiency, excess iron accumulates and raises long-term cardiovascular risk — and because iron is a leading cause of poisoning in young children, keep it well out of reach.
