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.

Gentle enough to keep taking
Iron supplements have been rough on my stomach in the past, so I started this one cautiously with food every other morning. After two weeks I moved to the schedule my doctor suggested. No constipation, no metallic taste, and no queasy commute, which already makes it easier to stay consistent. I follow a mostly plant-based diet and my cycles can be heavy, so my doctor checks my ferritin rather than having me guess from tiredness alone. At my latest check the conversation was encouraging, but I am continuing to follow the plan we set. The capsule is not tiny but it goes down without sticking, and there is no rusty smell when I open the bottle. I like that I can take it without planning my whole morning around side effects. If you have had a bad experience with standard iron, this is worth discussing with your own clinician. For me, consistency was the missing piece and this has made consistency possible

No constipation for me
I waited a full bottle before reviewing because iron products have disappointed my stomach before. My clinician suggested adding iron after checking my ferritin, and we will repeat the lab later rather than guessing from how I feel. I take this after breakfast with water and leave some time before coffee. The pleasant surprise is what did NOT happen: no heavy stomach and no backed-up feeling. By the fourth week I also stopped wanting to lie down the second I got home from work. The capsule is not tiny, but it is smooth and has no mineral aftertaste. I can actually stick with this one

Gentler for me
Iron has usually been hard for me to stick with because other brands made my stomach feel rough. This one has been much easier to take with lunch. I am plant-based and wanted something simple to add around my monthly cycle. No weird metallic taste, no dread when I see the bottle. I will keep it in the rotation.

Gentle enough for me
I had been putting off iron because the last one I tried made my stomach miserable and I was already tired of dealing with that. My doctor had suggested keeping an eye on my ferritin after a few heavy cycles, so I wanted an option I could actually tolerate while following that plan. I have taken this with breakfast for almost seven weeks. No constipation, no queasy feeling, and no metallic burps. I still take it with food because that works best for me. It is nice when a supplement does not become another thing to brace yourself for every morning. I will keep checking in at appointments, but this has been a much better experience than the cheap iron tablets I bought before.

finally gentle iron
I have tried several iron products and most made me constipated or nauseous. This one has been much gentler. I take it with food during my cycle and have not dreaded it. HUGE improvement over the old tablets I used to force down.

Good for heavy periods
Extremely heavy periods, constant iron battle. This supplement is the first that moved my levels without destroying my digestion. Taking it consistently.

Energy and mood improved together
Low iron does something weird to mood. I was irritable and flat all the time. Iron levels are back up and I feel genuinely happy most days. My doctor thinks the connection is real.

Hair is growing back
Low iron was causing my hair loss. Two months on this and my hair is thicker and growing back noticeably. Iron deficiency affects everything. Get your levels checked.

Brain fog lifted
Had no idea low iron was behind my constant mental fog. Doctor flagged my iron and I started this supplement. Six weeks later I feel sharp again. The brain-gut-blood connection is real.

Best iron supplement I've tried
Gone through maybe 6 different iron supplements over the years. This is the first that improved my levels, didn't constipate me, and that I actually look forward to taking.

Three years of anemia, finally addressed
Been anemic for three years. Tried iron pills that made me sick. Tried IV iron which was expensive and inconvenient. This whole food iron is gentle, effective, and I can take it every day without issue.

Plant-based iron that absorbs
Non-heme iron is less bioavailable but this whole food formula absorbs much better than the elemental tablets I was taking before. My levels actually moved.

Better than prescription iron
Was on prescription iron for 6 months. My doctor said I could try a food-based supplement. This is what I switched to. Better absorbed, no constipation, levels stayed good.

Consistent improvement over time
Week 4: slightly better energy. Week 8: noticeably better. Week 12: bloodwork confirmed. Iron deficiency takes time to correct but this is moving in the right direction.

Took with vitamin C
My nutritionist said to take iron with vitamin C to maximize absorption. Taking this with orange juice every morning. Levels moved faster than any previous iron supplement.

Marathon runner, iron maintained
I run marathons on a plant-based diet. Iron monitoring is constant — foot strike hemolysis and sweat losses mean my iron gets depleted faster than most people. I've struggled to keep my ferritin above 20 for years. This whole food iron keeps my levels stable through heavy training without any GI issues. That last part is key — I've tried other iron supplements and they wreck my gut during training blocks. This one doesn't. It's the only iron supplement I'll use.

This is a real gap in plant-based nutrition. This whole food iron fills it without the side effects of cheap elemental supplements. Highly recommend for any vegan or vegetarian.

Ferritin went from 9 to 34
My ferritin was at 9 for two years. I tried two other iron supplements during that time — one elemental iron that didn't move my levels at all, and one that caused such bad constipation I stopped after two weeks. My hematologist was getting ready to discuss IV infusions.
I asked to try one more oral supplement first and chose this whole food iron based on the absorption research. Three months later my ferritin was at 34. My hematologist actually said 'what did you change?' The constipation that came with every other iron supplement? Zero. Not once. My digestion is actually better than it was before I started.
I will take this supplement for the rest of my life if I have to. It solved a two-year problem.
