Consumer advice
If you've tried standard iron supplements (ferrous sulfate, ferrous gluconate) and had GI problems — constipation, nausea, cramping — heme iron from bovine spleen is a legitimate upgrade worth considering. The science behind better absorption and tolerability is real. Before buying, check if your doctor has confirmed iron deficiency with bloodwork (ferritin + hemoglobin). Don't self-diagnose and supplement blindly — excess iron is harmful. If cost is a concern, ferrous bisglycinate (e.g., Thorne Iron Bisglycinate, ~$15-20) is a gentler non-heme option that's cheaper and still well-tolerated. The PLUS version adds Methyl B-12 and Folate, which are genuinely useful co-factors for red blood cell production — a reasonable add-on if your diet is low in these. Buy the 3-bottle bundle if you commit; the 90-day timeline they recommend is accurate for meaningful ferritin improvement.
