Iron Bisglycinate 25 mg – 120 servings

Trust should be verifiable. Every batch we produce is tested by an independent laboratory, and the certificate of analysis for your exact lot is published on this page — potency, heavy metals, microbials. Testing begins the moment a raw material arrives, continues through production, and no batch is released until every result clears. The label is a claim. The COA is the proof.

We formulate from peer-reviewed clinical research and dose to match it. We select the highest-grade material available for each ingredient, in the form the body absorbs best, and where a patented or branded form is the one that has actually been studied, that is the one we use. Every active appears at its exact amount, with no proprietary blends and nothing added that doesn't need to be there.

In our own cGMP-certified facility in California's Central Valley. Manufacturing in-house means quality is our responsibility at every step rather than a supplier's promise. Raw materials are purchased through established US suppliers who import and qualify them, and every material is tested against our own specification before it enters production — wherever it originated.

Because of what goes in. We buy the highest grade of each raw material, in the most absorbable form, and we work with the branded and patented ingredient houses whose material the clinical research was actually run on — names like Lonza, Albion, RIBUS, Sabinsa and Indena. Wherever possible those materials are made domestically. Our capsules are titanium-dioxide free. Then it is made in our own facility and third-party tested batch by batch. Every one of those choices costs more than the alternative, and the price reflects it. Anyone can claim quality — we publish ours.

That is the right question and it deserves a straight answer: find out before you start. Iron is one of the few supplements where taking it when you don't need it can do harm, because the body has no easy way to get rid of a surplus. A blood test tells you your actual iron status. If you have not had one, get one, and take the result to a clinician rather than guessing from how tired you feel.

Iron Complex pairs a slightly higher iron amount with the B vitamins and vitamin C that work alongside it — folate, B12, B6 and riboflavin — in a 90-serving bottle. This is iron on its own at 25 mg, 120 servings, for people who already have the rest covered or who want to control each piece separately.

Balchem's ferrous bisglycinate chelate — each iron atom bound between two glycine molecules. That structure is what keeps it stable through the gut and is why chelated iron is generally better tolerated than free iron salts.

One capsule daily with food. Keep it away from calcium supplements, dairy, coffee, tea and antacids, which genuinely reduce iron absorption. If you take thyroid medication or certain antibiotics, ask your clinician how far apart to space them.

Do not take supplemental iron if you have haemochromatosis or another iron-storage disorder, or elevated iron levels. Speak with a qualified healthcare professional first if you are pregnant, nursing, taking medication or managing a medical condition. Keep it well out of reach of children — iron overdose is the leading cause of fatal poisoning in children under six.
