10 Best Iron Supplements For Anemia 2025 in the United States

THORNE Ferrasorb offers a comprehensive solution for those dealing with iron deficiency anemia. Each capsule contains 36 mg of elemental iron in the form of iron bisglycinate, which is known for being well-absorbed and less likely to cause constipation compared to other iron types. The presence of vitamin C, B vitamins (B6, B12), and folate enhances iron absorption, making the supplement more effective.

This is particularly beneficial for individuals experiencing symptoms like weakness, fatigue, and shortness of breath due to low iron levels. The inclusion of these essential nutrients supports overall blood health, addressing multiple factors that contribute to anemia beyond just iron deficiency. One notable advantage is the gluten-free formulation, catering to those with gluten sensitivities or celiac disease. Additionally, the product is trusted by professional teams and endorsed by institutions such as the Mayo Clinic, adding to its credibility.

On the downside, the capsule form might not be suitable for those who have difficulty swallowing pills. Furthermore, while the supplement aims to minimize side effects, individual reactions can vary, and it's important for users to monitor for any adverse effects such as gastrointestinal discomfort. The lack of flavor might be seen as a positive or negative depending on personal preference. In summary, THORNE Ferrasorb appears to be a well-rounded iron supplement, particularly effective for adults needing comprehensive blood support, although some users might need an alternative form if they struggle with capsules.
