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.

NovaFerrum Wow is a high-potency liquid iron supplement designed specifically for adults dealing with iron deficiency or anemia. Each 5mL dose provides a substantial 125mg of iron, which is a significant benefit for increasing iron levels efficiently. The liquid form is advantageous as it allows for quicker absorption and is generally gentler on the stomach compared to traditional iron tablets or capsules, making it a suitable option for those who experience gastrointestinal discomfort with pills.

This supplement is clinically proven to be safe, well tolerated, and effective, as highlighted in a study published in JAMA in 2017. Additionally, it is certified as Vegan, Gluten-Free, Kosher, and Halal, which makes it accessible to a wide range of individuals with dietary restrictions or allergies. The raspberry grape flavor might make it more palatable for some users.

However, some individuals might find the dosage too high and may need to consult a healthcare provider to adjust the amount taken. Also, while liquid iron can be easier to ingest, it may have a stronger taste that may not be appealing to everyone. Its sugar-free formulation is a plus for those watching their sugar intake. NovaFerrum Wow presents a strong option for adults needing an effective iron supplement, particularly those who prefer a liquid form and have specific dietary needs.
