Promix Iron

Do you feel like you're putting in the work, but there's just a lingering sense of sluggishness, fatigue? Low iron could be the hidden factor slowing you down—and most endurance athletes don't realize they're running on empty.

Promix Iron delivers 11mg of heme iron polypeptide, the most bioavailable form of iron your body can absorb. Unlike traditional iron supplements that wreak havoc on your gut, this formula absorbs 10x more efficiently while being gentle on your digestive system. That means you get the iron your muscles and red blood cells need without the stomach issues that make most athletes quit supplementing.

Iron deficiency is one of the most common nutrient deficiencies in endurance athletes—particularly females, runners, cyclists, and triathletes who log high-volume weeks. Promix Iron gives you clean, porcine-derived heme iron in a form your body recognizes. 

Promix Iron

Easy on Your Gut – Heme iron comes from animal sources and gets absorbed directly into your bloodstream—no conversion needed. Your body recognizes it instantly and puts it to work building hemoglobin and supporting oxygen transport to working muscles. A common barrier to iron supplementation is the nauseousness that it creates — until now. 

Performance Support – Adequate iron levels support cardiovascular fitness, improve mood stability, and help maintain energy throughout long training blocks. When your ferritin stores are optimized, your body can adapt better to training stress and recover faster between sessions.

Flexible Dosing – Take it with or without food. Coffee, tea, dairy—none of them interfere with absorption like they do with plant-based iron supplements. One capsule daily keeps your iron stores topped off without disrupting your routine.

How to Take Promix Iron

Take 1 capsule daily in the morning or as directed by a medical professional with or without food. Absorption is not impacted by vitamin C, dairy, coffee, or tea.

We recommend consulting with a professional and ensuring you have low iron + need supplementation.
