Why You Should Buy This

• Formulated for absorption, not just iron content. Iron on its own can be poorly absorbed and hard on digestion; pairing it with vitamin C, B6, B12, and folate is a formulation approach specifically intended to support better uptake and utilization.
• Practitioner-trusted brand. THORNE has a strong reputation within clinical and practitioner communities, which speaks to consistency and quality expectations.
• Addresses a genuinely common nutrient gap. Iron deficiency is one of the most common nutrient deficiencies, particularly in certain populations (see FAQ below), making this a relevant supplement for many people — though it should be confirmed with testing, not assumed.
• Comprehensive B-vitamin and folate support. Rather than iron alone, the added B6, B12, and folate contribute to broader nutrient support relevant to red blood cell formation.
• Trusted in performance and athletic contexts. Used by professional sports teams and national athletic teams, reflecting quality and reliability expectations at a competitive level.

What You Should Use It For

THORNE Ferrasorb is best suited for:

• Adults with a confirmed or practitioner-identified need for iron supplementation
• Supporting healthy red blood cell formation and oxygen delivery
• Addressing fatigue specifically linked to low iron status (confirmed via bloodwork, not assumed from fatigue alone)
• Athletes or highly active individuals with elevated iron needs
• Use under practitioner guidance, since iron supplementation should generally be based on confirmed need rather than routine daily use by everyone

FAQ

What is THORNE Ferrasorb used for?
Ferrasorb is an iron supplement formulated with 36mg of bioavailable iron plus Vitamin C, B6, B12, and Folate, designed to support healthy iron levels, red blood cell formation, and oxygen delivery.

Should everyone take an iron supplement?
No. Iron supplementation is generally recommended based on a confirmed deficiency or increased need (identified through bloodwork), not as a routine supplement for everyone. Taking iron supplements without a confirmed need isn't advisable, since excess iron can build up in the body and cause harm over time. Consult a healthcare provider and consider bloodwork before starting iron supplementation.

Can too much iron be harmful?
Yes. Unlike many vitamins, iron can accumulate in the body, and excess iron intake — especially in people who don't have a deficiency — can be harmful. This is a key reason iron supplements should be used under guidance rather than taken indiscriminately.

Why are Vitamin C, B6, B12, and Folate included with the iron?
These nutrients are included to support iron absorption and to contribute to broader nutritional support for red blood cell formation, working alongside the iron rather than functioning independently.

Will this help with fatigue?
If fatigue is specifically related to low iron status, addressing that deficiency may help support energy levels. However, fatigue has many possible causes, and iron supplementation is only appropriate — and only likely to help — if an iron deficiency has actually been identified.

Is Ferrasorb easy on digestion?
THORNE positions Ferrasorb as a well-absorbed, practitioner-favored iron formulation. Individual digestive tolerance to iron supplements can still vary; take with food if you experience stomach discomfort, unless otherwise directed.

How many servings are in one bottle?
Each bottle provides 60 servings.

Who should consider taking Ferrasorb?
Adults with a confirmed or practitioner-identified iron deficiency, including athletes or highly active individuals with elevated iron needs, ideally used under healthcare guidance with appropriate testing.

This product is a dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease, including iron-deficiency anemia. Individual results may vary. Consult your healthcare professional and consider bloodwork before beginning iron supplementation, particularly if you are pregnant, nursing, taking medication, or have an existing health condition. Keep out of reach of children — accidental iron overdose is a leading cause of fatal poisoning in children under 6.
