Most iron supplements don't tell you what form of iron is inside the capsule — or they use ferrous sulfate, the cheapest form available, and dress it up with a modern label. We use ferrous bisglycinate chelate and print the exact dose of every nutrient on the label. No proprietary blends hiding the real numbers. Every batch is tested through an independent, ISO-certified lab before it ships. The Certificate of Analysis is published on our website. You can verify exactly what you're taking before you swallow a single capsule. If transparency were standard in this category, this question wouldn't need to exist.*

That $12 bottle is ferrous sulfate — the form that causes constipation, absorbs poorly, and doesn't include a single cofactor for dopamine production. It was designed to treat anemia at the lowest possible cost. Ferritin Support contains chelated bisglycinate iron (3.5x better absorption), five cofactors specifically chosen for the brain iron–dopamine pathway (B6, B12, Folate, Zinc, Vitamin C), Piperine for bioavailability, Probiotics for gut protection, and six botanical support ingredients. It's thirteen nutrients replacing three to four separate bottles most people buy individually. The comparison isn't price per bottle — it's what actually reaches your brain per dollar spent.*

This is the most important question on this page. There are three reasons the iron you tried before probably didn't work. First, the form — ferrous sulfate absorbs poorly and most of it never makes it past your gut. Second, the dose — most gentle iron supplements deliver 18–25mg, well below what the research says is needed to move ferritin into the 75–100 range where legs begin to calm. Third, and most commonly missed — iron alone isn't enough. Your brain needs B6, B12, and Folate to convert iron into dopamine. Without those cofactors, iron reaches the blood but never becomes the neurotransmitter your legs are actually missing. This formula addresses all three failures in one serving.*

Iron is a mineral your body requires daily. The 40mg in this formula is below the FDA's Tolerable Upper Intake Level of 45mg for adults. That said, we recommend getting your ferritin and transferrin saturation tested before you start — not because the supplement is risky, but because knowing your number helps you track your progress and gives you a baseline. If your ferritin is already above 100, you likely don't need additional iron. If you take thyroid medication, antibiotics, or antacids, space them at least two hours apart from iron. And if you have hemochromatosis or a known iron overload condition, iron supplementation is not appropriate for you. We'd rather lose a sale than put the wrong product in the wrong hands.

Every batch. Not one batch from 2023 that we reference on every label since. Every production run is tested through an independent, ISO 17025-certified lab for potency, purity, and contaminant screening. The results are published as Certificates of Analysis on our website. You can look up your specific batch before you take it. This is the standard the industry should have but mostly doesn't.

Brain iron doesn't rebuild overnight. Ferritin levels build gradually — most people see their numbers begin to move within four to six weeks, with meaningful changes in leg comfort typically reported between week four and week eight. Some people notice subtle improvements earlier. Some take the full eight weeks. The clinical research on iron for restless legs measures outcomes at 12 weeks for this reason. We built the 90-day guarantee around that timeline so you have enough time to feel the difference without risking a single dollar. If your legs aren't calmer by day 90, you get a full refund.
