ActivNutrients Without Iron is a comprehensive multivitamin-mineral formula from Xymogen designed for adults seeking broad-spectrum micronutrient support without added iron, a consideration for men, post-menopausal women, or those whose iron levels are already well maintained. It delivers activated B vitamins (including methylfolate and methylcobalamin), chelated minerals, and fat-soluble nutrients in forms selected for enhanced absorption.
Why It's Worth Considering: Xymogen is a practitioner-grade brand, and this formula reflects that standard, using bioavailable coenzyme and chelated forms rather than cheaper oxide or cyanocobalamin alternatives.

More category questions
What is the best form of iron supplement?
Iron bisglycinate (Ferrochel) is the best-tolerated form with high absorption and minimal GI side effects. Ferrous sulfate is the most studied but commonly causes constipation and nausea. Heme iron polypeptide has the highest absorption rate but is animal-derived.
Why does iron cause constipation?
Non-chelated iron forms (ferrous sulfate, fumarate) are poorly absorbed — the unabsorbed iron irritates the gut lining and slows peristalsis. Chelated forms (bisglycinate) are absorbed more completely, leaving less unabsorbed iron in the gut. Taking vitamin C improves absorption and reduces GI side effects.
Can I take iron with other supplements?
Separate iron from calcium, zinc, magnesium, and dairy by 2+ hours (they compete for absorption). Separate from thyroid medication by 4+ hours. DO take iron WITH vitamin C (doubles absorption). Avoid taking with coffee or tea (tannins reduce absorption by 60%).
How do I know if I need iron?
Get a complete iron panel: serum ferritin (most sensitive — optimal is 50-100 ng/mL), serum iron, TIBC, and transferrin saturation. Symptoms of deficiency: fatigue, cold hands/feet, pale skin, brittle nails, shortness of breath, brain fog, and restless legs. Ferritin below 30 ng/mL warrants supplementation in most cases.
