Proferrin Clear
You're three weeks deep in a build block and suddenly every workout feels harder than it should. Recovery's off. Breathing's labored on easy runs. Before you question your fitness, check your iron. 15-35% of female endurance athletes and 3-11% of male athletes deal with iron deficiency—and most iron supplements create more problems than they solve.
Proferrin Clear delivers heme iron polypeptide—the same form of iron your body absorbs from red meat, now in a clean dye-free capsule. Clinical studies show heme iron absorption rates of 15-35%, compared to just 2-10% from standard iron pills. This isn't just better absorption. It's a completely different pathway that sidesteps the gut issues that make most athletes quit their iron supplements.
What Makes It Different
10x Better Absorption Than Standard Iron – Proferrin Clear uses your body's natural heme iron pathway—the same one that processes iron from a steak. One capsule delivers as much absorbable iron as 23 chicken breasts, without planning meals around coffee, calcium, or acid blockers.
Zero Gut Drama – Traditional iron supplements cause nausea, constipation, and stomach pain. Proferrin's small dose (10.5mg per capsule) means your gut processes what it needs without the usual side effects. Take it with breakfast, with your coffee, whenever.
The Science of Iron
Heme iron polypeptide is derived from bovine hemoglobin and absorbed through specialized receptors in your intestinal wall. Endurance athletes face increased iron loss through foot-strike hemolysis, GI bleeding, and sweat. Your body can't make iron, so when stores run low, performance tanks.
How to Use Proferrin Clear
Take 1-3 capsules daily with or without food. If you're deep in training or have confirmed low ferritin (below 30-50 μg/L for athletes), start with 2-3 capsules. Once levels normalize, 1 capsule maintains stores without overdoing it. Get your ferritin checked every 8-12 weeks to dial in your dose.
Athletes who've struggled for years with low ferritin report finally hitting normal ranges after switching to heme iron. Distance runners, cyclists, and rowers use it to maintain iron levels without the nausea that sidelines traditional supplementation.
