Participants with iron-deficiency anemia who received chelated iron supplementation showed statistically significant improvements in hemoglobin levels and serum ferritin compared to those who received placebo; the specific chelate form studied may differ from the rice protein chelate used in this product.
Randomized controlled trial; n=60; 8 weeks; participants with iron-deficiency anemia
Participants with iron-deficiency anemia who received a chelated iron preparation showed statistically significant increases in hemoglobin and serum ferritin compared to baseline, with gastrointestinal adverse events reported at lower rates than those typically associated with non-chelated iron forms.
Adults with metabolic syndrome who received rice bran supplementation showed statistically significant reductions in fasting blood glucose and triglycerides compared to those who received placebo; the dose and form of rice bran administered in the study differs from the quantity present as a trace ingredient in this supplement.
Adults with impaired fasting glucose who received rice bran extract showed statistically significant improvements in fasting glucose and postprandial blood glucose compared to those who received placebo; the dose and form of rice bran used may differ from the rice bran quantity in this product.

How it works
Every ingredient, chosen with intention.
Here's what's in this bottle - and why each ingredient earned its place in the formula.
Iron
as rice protein chelate
A trace mineral the body uses to form hemoglobin in red blood cells, which carries oxygen from the lungs to tissues, and myoglobin in muscle tissue. Delivered as a rice protein chelate, iron bonded to rice-derived protein, which travels through the digestive tract without releasing free iron ions that can cause gastrointestinal discomfort.
Why we chose it
Ferrous sulfate, the cheapest and most common form of supplemental iron, is notorious for stomach upset and constipation. Rice protein chelate is gentler because the protein binding reduces the mineral's direct contact with the GI lining.
Rice Bran
the outer layer of the rice grain
The nutrient-dense outer layer of the rice grain, containing naturally occurring B vitamins, minerals, and fiber in a whole food matrix.
Why we chose it
Including 60mg of rice bran alongside the chelated iron means the formula carries the full grain context, not just an isolated mineral compound. The bran layer is where the rice plant concentrates much of its natural mineral content.

Questions, answered
What customers often ask.
Why is rice protein chelate gentler than ferrous sulfate?
Ferrous sulfate, the cheapest and most common supplemental iron, releases free iron ions directly in the GI tract, which is what causes constipation and nausea. Rice protein chelate binds iron in a stable complex that reduces direct contact with the gut lining, allowing it to absorb with less irritation.
When is the best time to take iron?
Iron absorbs best on an empty stomach. If you experience any GI sensitivity, taking it with a small amount of food helps. Avoid combining it with calcium-rich foods or supplements at the same time, as calcium competes with iron for absorption.
Does vitamin C help iron absorption?
Yes, vitamin C enhances non-heme iron absorption meaningfully. Taking your iron supplement alongside a glass of citrus juice or a vitamin C supplement can increase how much your body absorbs. The citrus bioflavonoids in the formula's other ingredients provide some natural synergy here as well.
Is 18mg enough if I have low iron levels?
18mg is 100% of the daily reference value for general wellness in adults. If you've been diagnosed with iron deficiency or deficiency anemia, therapeutic doses are typically higher and prescribed under medical guidance. Please consult your healthcare provider before self-supplementing if your levels are clinically low.
Is this safe for men to take?
Men have a lower iron requirement than premenopausal women (8mg vs. 18mg DV). Men who don't have a documented deficiency and who eat iron-containing foods may not need supplemental iron, excess iron accumulates in tissue rather than being excreted. Consult your healthcare provider to confirm this is appropriate for your situation.
What else is in the capsule besides iron?
The other ingredients include rice bran (60mg), citrus bioflavonoids, and a blend of whole food powders, organic spinach, tomato, carrot, and kale. These appear in small amounts as part of the whole food formulation philosophy, not as therapeutic doses of those foods.
