Size: 118 Milliliters
Iron Tonic by Vitanica is a liquid iron supplement formulated to support healthy iron levels and red blood cell production in adults, particularly women with higher iron demands. Delivered as a 118 mL liquid preparation, it provides iron in a form designed for convenient dosing and absorption.
Why It's Worth Considering: The liquid format allows for flexible dosing and may be easier to tolerate digestively compared to standard iron tablets, making it a practical option for those sensitive to traditional iron supplements.

| GI Side Effects | Minimal | Common (constipation) | Moderate | Minimal |
| Best For | Sensitive stomachs | Budget, proven | Higher elemental iron | Maximum absorption |
| Take With | Empty stomach OK | Vitamin C required | Vitamin C helps | Anytime |
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.
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.
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%).
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.
