Mixed consensus: iron supplementation helps fatigue and anxiety, but testing urged before use; practitioner endorsement is common.
PhytoMulti® with Iron is a practitioner-formulated multivitamin from Metagenics that combines essential vitamins and minerals with a proprietary blend of phytonutrients and plant extracts to support foundational cellular health and overall vitality. Designed for adults who may have higher iron needs, such as premenopausal women or those with low dietary iron intake, it pairs micronutrient support with broad-spectrum botanical compounds.
Why It's Worth Considering: PhytoMulti® distinguishes itself through Metagenics' phytonutrient-forward formulation philosophy, incorporating concentrated plant compounds alongside core vitamins and minerals rather than relying on isolated nutrients alone.
| Feature | Bisglycinate (gentle) | Ferrous Sulfate | Ferrous Fumarate | Heme Iron |
|---|---|---|---|---|
| Absorption | High (chelated) | Moderate | Moderate | Highest (animal-derived) |
| 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.
