NutraBio Iron Glycinate delivers 25mg of elemental iron per capsule as Ferrochel® — the patented ferrous bisglycinate chelate from Albion Minerals, widely recognized as the most bioavailable and stomach-friendly form of supplemental iron available. Where conventional iron salts (ferrous sulfate, ferrous fumarate) carry a positive ionic charge that can irritate the gastrointestinal lining and block the absorption of other nutrients, Ferrochel® is ionically neutral — it passes through the intestinal wall intact via amino acid transport pathways rather than competing with other minerals or disrupting GI tissue. The result is more iron absorbed, less iron wasted, and none of the nausea, constipation, or GI discomfort that low-quality iron supplements are notorious for. Single ingredient. Vegetarian capsule. No gluten, no lactose, no artificial colors, flavors, or sweeteners. 60 capsules per container — a full two-month supply at one capsule daily. Take 1 capsule daily preferably with meals. Third-party batch tested and verifiable at CheckMySupps.com. NutraBio Forever and a Day Guarantee.†

Why Iron Form Matters — Ferrochel® vs. Conventional Iron
Iron supplementation has a reputation problem that is almost entirely a delivery problem. Ferrous sulfate — the cheapest and most commonly used iron form in supplements and pharmaceutical iron tablets — is an inorganic iron salt. It absorbs poorly, with bioavailability estimates in the range of 2-14% depending on the individual's iron status and GI environment. What doesn't absorb stays in the intestinal lumen, where unabsorbed ionic iron reacts with the intestinal mucosa to produce oxidative damage — the mechanism behind the nausea, cramping, constipation, and dark stools that most people associate with iron supplementation. Conventional iron also carries a positive ionic charge that causes it to interact with and block the absorption of other minerals (zinc, calcium, magnesium) and some vitamins — a significant concern in any supplement stack or multivitamin context.†
Ferrochel® (Ferrous Bisglycinate Chelate) from Albion Minerals solves all of these problems through the chelation mechanism. In Ferrochel®, each iron atom is bound to two glycine amino acid molecules through coordinate covalent bonds — fully encapsulating the iron in an amino acid "cage" that renders it ionically neutral. The neutral charge means Ferrochel® does not compete with other minerals for absorption transporters and does not react with GI mucosa the way ionic iron does. Instead of relying on the inefficient iron-specific absorption pathway that conventional iron uses, Ferrochel® is absorbed primarily through the amino acid transporter pathway (specifically the DMT1 and PepT1 pathways) — the same highly efficient absorption mechanism used by dietary amino acids. This results in documented bioavailability improvements of 4-6x versus ferrous sulfate in head-to-head comparative studies.†
What Iron Does — Why Deficiency Is More Common Than Most People Realize
Iron is an essential mineral required for hemoglobin synthesis — the iron-containing protein in red blood cells that binds oxygen in the lungs and releases it in tissues throughout the body. Without adequate iron, hemoglobin production falls, red blood cell oxygen-carrying capacity decreases, and every cell in the body receives less oxygen than it needs for normal function. The consequences — fatigue, brain fog, reduced exercise performance, impaired immune function, and disrupted temperature regulation — are among the most common symptoms of suboptimal nutrition, and they frequently go unrecognized because they develop gradually as iron stores (ferritin) deplete over weeks and months before clinical anemia develops.†
Iron deficiency is the most prevalent nutritional deficiency in the world — the World Health Organization estimates that iron deficiency affects over 2 billion people globally. In developed countries it is particularly common in premenopausal women (due to menstrual blood loss), female athletes (through sports anemia mechanisms including foot-strike hemolysis and increased iron losses through sweat), vegetarians and vegans (who consume only non-heme iron with significantly lower bioavailability than heme iron from meat), frequent blood donors, and individuals with GI conditions that impair absorption. For these populations, adequate iron supplementation in a bioavailable, stomach-friendly form is not optional for optimal health and performance.†
Iron and Athletic Performance — The Overlooked Recovery Variable
For the Get Yok'd customer base specifically, iron's relevance extends beyond general health into athletic performance. Daily iron supplementation supports red blood cell production, healthy energy levels, oxygen transport, and focus — all of which directly affect training capacity and recovery quality. Iron's role in myoglobin (the oxygen-storing protein in muscle tissue, distinct from hemoglobin) means that adequate iron status supports the aerobic capacity of muscle tissue itself, not just the oxygen delivery from blood. Female athletes are the population most likely to benefit most from iron supplementation — the combination of menstrual iron losses and exercise-related iron depletion creates a compounding deficit that significantly impairs performance in a high percentage of female athletes who are unaware that iron status is the limiting variable in their recovery and endurance.†
The fatigue and reduced training capacity that iron deficiency causes can develop well before hemoglobin levels drop to clinically anemic ranges — ferritin levels below 30 ng/mL (iron stores depleted but not yet severely anemic) are associated with measurable impairments in exercise performance and significantly elevated perceived exertion. Addressing suboptimal iron stores before clinical anemia develops is the proactive approach that NutraBio Iron Glycinate supports with its daily 25mg Ferrochel® dose in a two-month supply format that facilitates consistent supplementation.†
The Upgraded Formula — 25mg vs. the Previous 18mg Version
The previous version of NutraBio's iron supplement used chelated iron at 18mg. The refreshed Iron Glycinate specifically upgrades to Ferrochel®-branded ferrous bisglycinate chelate at 25mg — a 38% increase in iron content in the same single-capsule daily serving. The switch from generic chelated iron to the Ferrochel® branded compound is equally significant: Ferrochel® has over two decades of published clinical research specifically on this branded form (not just ferrous bisglycinate generically), with studies confirming its efficacy for iron status improvement in pregnant women, children, athletes, and iron-deficient adults at this specific 25mg dose. The upgrade reflects NutraBio's ongoing commitment to using the highest quality, most research-supported form of each ingredient across their lineup — the same philosophy that drives their use of Albion® Di-Magnesium Malate in their electrolyte formulas and Creapure® in their creatine products.†
Ferrochel® Clinical Research — The Evidence Base
Ferrochel® (ferrous bisglycinate chelate) has been studied specifically at the 25mg dose in multiple randomized controlled trials. A study published in the Journal of Perinatal Medicine (Milman et al., 2014) found that ferrous bisglycinate at 25mg iron was as effective as ferrous sulfate at 50mg iron for preventing iron deficiency during pregnancy — meaning Ferrochel® achieved the same clinical outcome at half the elemental iron dose, reflecting its superior bioavailability. A study published in Nutricion Hospitalaria (Duque et al., 2014) compared ferrous sulfate and ferrous bisglycinate chelate for improving ferritin levels in school-aged children and found that the bisglycinate chelate produced comparable ferritin improvements with significantly better GI tolerance. These studies specifically using Ferrochel® at 25mg provide direct clinical support for NutraBio's chosen form and dose.†
Frequently Asked Questions
Why is Ferrochel® better than ferrous sulfate or ferrous fumarate?
Ferrous sulfate and ferrous fumarate are inorganic iron salts that absorb inefficiently (2-14% bioavailability) and leave significant unabsorbed iron in the intestinal tract where it causes oxidative irritation — the source of the nausea, constipation, and GI discomfort most people experience with conventional iron supplements. Ferrochel® binds iron to two glycine amino acids, rendering it ionically neutral and absorbing it through the more efficient amino acid transport pathway. Head-to-head bioavailability studies document 4-6x better iron absorption from Ferrochel® versus ferrous sulfate, meaning you absorb more iron from 25mg of Ferrochel® than from 100-150mg of ferrous sulfate — with none of the GI side effects.†Who is most likely to benefit from iron supplementation?
Premenopausal women (especially those with heavy menstrual periods), female athletes of any sport, vegetarians and vegans, frequent blood donors, endurance athletes, individuals with GI conditions affecting mineral absorption (Crohn's, celiac, IBD), and anyone experiencing unexplained fatigue, brain fog, or reduced exercise performance are the populations most likely to have suboptimal iron status. A serum ferritin test (the most sensitive measure of iron stores) is the best way to confirm whether iron supplementation is indicated — ferritin below 30 ng/mL often produces performance-relevant symptoms even without clinical anemia.†Can NutraBio Iron Glycinate be taken with other supplements?
Yes — Ferrochel®'s ionic neutrality means it does not block the absorption of other minerals the way conventional iron does. Standard ionic iron competes with calcium, zinc, and magnesium for absorption transporters. Ferrochel® uses amino acid transporters rather than mineral ion transporters, so it can be taken alongside a multivitamin, calcium supplement, or any mineral-containing product without the absorption interference that makes conventional iron timing-sensitive.†Is NutraBio Iron Glycinate appropriate for vegetarians and vegans?
Yes. The capsule shell is vegetable cellulose (not gelatin). The Ferrochel® iron glycinate itself is produced through a synthetic chelation process that does not involve animal-derived ingredients. The formula contains no lactose, no gelatin, no animal-derived excipients, and is free from gluten. Vegetarians and vegans — who are among the most iron-deficient populations due to the lower bioavailability of plant-sourced non-heme iron — are ideal candidates for Ferrochel® supplementation.†
How to Take NutraBio Iron Glycinate
Take 1 capsule daily, preferably with a meal. Taking with food improves iron absorption for most individuals and further reduces any potential GI sensitivity. For best absorption, avoid taking with calcium-rich foods or calcium supplements (dairy, antacids) within 1-2 hours — calcium can mildly reduce iron absorption even from well-formulated chelated forms at high calcium doses. Vitamin C (ascorbic acid) at 100-200mg taken alongside iron enhances absorption by reducing ferric iron to the more absorbable ferrous form — a glass of orange juice or a Vitamin C supplement alongside the iron capsule is a practical absorption optimization strategy. Take consistently daily for best results — iron stores (ferritin) replenish gradually over weeks of consistent supplementation. Not for persons under 18 without physician guidance. Consult a physician before use if taking any prescription medications — particularly thyroid medications (iron can reduce levothyroxine absorption) or antibiotics (iron can reduce fluoroquinolone and tetracycline absorption when taken simultaneously).†
