If This Sounds Like You, You're Not Alone
These aren't random. They're connected. And millions of women experience them without ever knowing why.
The Hidden Deficiency
Iron deficiency is the most common nutritional deficiency in the world. And it disproportionately affects women — because women need up to 3x more iron than men, yet eat fewer calories, less red meat, and lose iron every single month through menstruation.
Men need 8mg of iron per day. Menstruating women need 18mg. Pregnant women need 27mg. Yet the average woman's diet provides just 12-13mg.
Iron is the core atom at the center of hemoglobin — the molecule that carries oxygen from your lungs to every cell in your body. When iron is low, your body can't make enough hemoglobin. Less hemoglobin means less oxygen reaches your tissues.
Your body responds by triaging. Critical functions get priority. Everything else gets rationed. Hair growth, nail strength, cognitive sharpness, stable mood, energy, libido — all deprioritized. You're not broken. You're running on empty.
If you've felt off for months or years and no one can tell you why, low iron may be the answer. But the type of iron you take matters more than you think.
The lab range problem:
Standard lab "normal" for ferritin starts at just 12 ng/mL. But research shows symptoms begin when ferritin drops below 30-50 ng/mL.
That means you can be severely depleted — exhausted, foggy, losing hair — and your doctor may tell you "your labs look normal."
This is why so many women walk away still feeling terrible. The standard isn't wrong. It's just not looking for the right thing.
Not All Iron Is Created Equal
Most iron supplements use non-heme iron — ferrous sulfate, ferrous gluconate, ferrous fumarate, iron bisglycinate. Your body absorbs just 2–20% of non-heme iron, and even that requires an empty stomach, no coffee, no tea, no dairy, no grains, plus vitamin C to help it along. Miss any of those rules and absorption drops even further.
| Non-Heme Iron | Sévra (Heme Iron) | |
|---|---|---|
| Absorption rate | 2–20% (highly variable) | 15–35% (consistently high) |
| Stomach issues | Common — nausea, constipation | Rare |
| Empty stomach required? | Usually, for best absorption | No — take anytime |
| Blocked by coffee or tea? | Yes — up to 60–90% reduction | No |
| Blocked by grains, beans, nuts? | Yes (phytates) | No |
| Requires vitamin C to absorb? | Yes | No |
| Affected by calcium? | Yes, even at low doses | Only at very high doses (800mg+) |
| Raises ferritin effectively? | Slowly, if tolerated | Faster, with better compliance |
Sévra delivers heme iron from the most potent natural source that exists — grass-fed beef spleen — in a clean, easy daily capsule. Enhanced with black pepper extract to maximize absorption, so more of every capsule reaches your blood.
How Sévra Works
What's Inside
Grass-fed, pasture-raised beef spleen (desiccated) — the most iron-dense whole food in nature, rich in naturally occurring heme iron
Naturally occurring heme iron — the same bioavailable form found in red blood cells, absorbed at 15–35%
Naturally occurring B12, peptides & protein — including tuftsin and splenopentin, which support immune function
Black pepper extract (piperine) — clinically shown to enhance mineral absorption, so more of every capsule reaches your blood
Frequently Asked Questions
Most iron supplements use non-heme iron (ferrous sulfate, ferrous gluconate, etc.), which your body absorbs at just 2–20% — and which commonly causes nausea, constipation, and stomach cramps. Sévra uses heme iron, sourced from grass-fed beef spleen, which is absorbed at 15–35% through a completely different pathway. It's gentler on your stomach, doesn't require an empty stomach, and isn't blocked by coffee, tea, or most foods.
This is the #1 reason women switch to Sévra. Heme iron does not cause the nausea, constipation, or stomach cramps associated with ferrous sulfate and other non-heme iron supplements. Most women tolerate it easily, even those who couldn't tolerate other iron products.
Most women notice improved energy and mental clarity within 2–4 weeks. Ferritin levels typically begin to rise within 4–8 weeks. Full iron repletion can take 3–6 months depending on your starting levels — which is why the subscription makes the most sense for lasting results.
Yes. Unlike non-heme iron, heme iron is not blocked by phytates, tannins, or polyphenols — so your coffee, tea, and meals are fine. It also doesn't require vitamin C to absorb. The one thing to be mindful of is high-dose calcium supplements (800mg+). If you take a calcium supplement, take it at a different time of day.
Iron supplementation is widely recommended during pregnancy — pregnant women need up to 27mg of iron per day. Heme iron is a food-derived form of iron with high bioavailability. As with any supplement, we recommend consulting your healthcare provider before starting.
