WHOLE-FOOD ORGANS◆100 MG effera®◆NO PROPRIETARY BLEND
Inside the formula / 03
Three targeted ingredients.
Nothing proprietary.
Spleen
100 mgA whole-food source of heme iron and natural cofactors. The label does not declare an elemental iron amount.
Traditional contextAn iron-rich food within nose-to-tail eating traditions.effera® human lactoferrin
100 mgAn iron-binding protein made through precision fermentation. Ingredient research explores iron management, immune function and cellular signaling.
Traditional use describes historical food or botanical use; it is not evidence that this product diagnoses, treats, cures or prevents disease.
The effera® difference
Iron is only
part of the story.
Lactoferrin is an iron-binding protein. Vital Woman pairs whole-food organs with 100 mg of effera® human lactoferrin, made through precision fermentation, to support healthy iron utilization.

Iron status deserves follow-through.
58.1%of 13,084 patients had no documented resolution of iron deficiency within three years in one health-system study. Women made up 90.7% of that persistent group.
This study did not test lactoferrin or Vital Woman, and it does not show that either replaces prescribed iron treatment.

Both women used other supplements; one took effera® within Super Core. This uncontrolled case series did not test finished Vital Woman or establish cause and effect.
Evans et al. · Cureus, 2026 ↗Understand the laboratory research
Helaina reports a 63% reduction in an inflammatory response in ex vivo human immune-cell work. This laboratory observation is not a measured reduction in inflammation in people taking Vital Woman.
Helaina also describes an uptake comparison of up to 4× versus bovine lactoferrin. It is an ingredient comparison, not evidence that Vital Woman delivers four times better iron absorption. The complete study method and dose are needed to interpret this comparison.
Read the supplier’s research summary ↗If you suspect low iron, work with your healthcare professional to understand the cause and monitor appropriate blood markers. Do not replace or change prescribed treatment based on this page.
The Human Nature difference
A different approach to iron support.
Female organ tissues, bison spleen and effera® lactoferrin bring three distinct ingredients into one formula.

“We've both felt so restored that we're now training for a Hyrox event together. It really does feel like getting our normal selves back.”

Source is part of the formula
Raised on land. Not built in a lab.
Human Nature works with 50+ independently owned bison ranches and is a Partner in Restoration with the National Bison Association. Better sourcing should support the animal, the grassland, the rancher and the person taking the finished formula.
- Grass-fed, pasture-raised American bison
- Whole organs, never imitation nutrients
- Third-party tested for purity
- 100% Made in the USA

The right nutrients, in context.
Vital Woman combines organ-specific whole-food nutrition with spleen and lactoferrin. The goal is not a mega-dose—it is a focused daily signal the body can recognize and use.
Good questions
Know before
you start.
These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.
01What packaging arrives with a subscription?+
Each subscription shipment contains refill pouches. A matching reusable metal canister is included as a free gift with the first standalone subscription shipment.
02What is in Vital Woman?+
Each two-capsule serving contains 800 mg female reproductive organs—uterus, ovaries and fallopian tubes—100 mg spleen and 100 mg effera® human lactoferrin. The panel lists the female organs as Bison/Bovine and the spleen as Bison. Gelatin is the only listed Other Ingredient.
03Does Vital Woman contain iron?+
Spleen naturally contains heme iron, but the label does not declare an elemental iron amount. Vital Woman is not an isolated iron tablet. If you monitor iron status, review the formula with your healthcare professional. The full measured nutrient breakdown is coming soon; see the formula disclosure on this page.
04What is effera®?+
A bio-identical human lactoferrin made by Helaina through precision fermentation. Vital Woman contains 100 mg per serving.
05Is Vital Woman clinically proven?+
The ingredient effera® has clinical and preclinical research. That does not establish clinical proof for the finished Vital Woman formula. Study design, dose and context matter; the evidence section links the original sources.
06Is this hormone replacement therapy?+
No. Vital Woman is a dietary supplement, not HRT or a prescription treatment. Organ tissues naturally contain biological compounds; discuss use with your clinician if you have a hormone-sensitive condition or use hormone therapy.
07When should I take it?+
Take two capsules daily with food and water, or as directed by your healthcare professional.
08Can I use it during pregnancy or breastfeeding?+
Consult your obstetrician, midwife or other qualified healthcare professional before use during pregnancy, while trying to conceive or while breastfeeding. Vital Woman is not a prenatal vitamin.
09Can I take it with iron supplements or medication?+
Do not change prescribed treatment based on this page. Review your iron markers, supplements and medications with your healthcare professional before combining products.
010Is it third-party tested?+
Human Nature reports nine independent heavy-metal and microbial checks. Open the testing details on this page. The laboratory report and lot-specific measurements are coming soon.
011Can I combine it with Human Potential and Fine Tune?+
Human Potential is the broad foundation, Vital Woman the female-specific layer and Fine Tune the mineral layer. Review the combined labels and your individual needs with your healthcare professional.
012What if it is not for me?+
Every first order is covered by the 90-day money-back guarantee.
