We Asked RDs What Iron Supplements They Recommend for Men — Here’s What They Said

While FullWell is a brand that is primarily focused on supporting women’s fertility, its iron supplements are an excellent choice for anyone in need of high-quality iron support. Crafted by a registered dietitian, these supplements follow the U.S. Food and Drug Administration’s Current Good Manufacturing Practices (CGMP) and undergo thorough in-house and third-party testing, delivering trust and reliability.

Its balance of therapeutic effectiveness and gut-friendly design makes it a top option for men in need of targeted iron support.

One potential drawback is that it may not appeal to those who are looking for a supplement that only contains iron. Further, the amount of iron per tablet (26mg) is above the daily recommended dose, so you will want to check with your doctor first before adding this supplement to your regimen.

However, this product stands out overall for men on a plant-based diet who are seeking an iron supplement for additional nutritional support.

A minor drawback for some users might be that this product doesn’t contain additional ingredients like vitamin C to help with absorption. Still, for those who want a simple product, Thorne Iron Bisglycinate is an excellent addition to any athlete’s regimen.

This supplement delivers 27 mg of iron in each tablet, providing an effective dose to support men with an iron deficiency or those requiring additional iron intake. The brand’s commitment to quality is also a standout feature. “Another reason I love Doctor’s Best High Absorption Iron is that all Doctor’s Best products are third-party tested for quality, purity, and consistency,” says Glinski. “They’re also produced in a CGMP-certified facility, ensuring they meet the manufacturing standards put in place by the FDA.”

One potential downside might be the supplement’s basic formulation, since it doesn’t include additional nutrients, such as vitamin C and B vitamins, which some iron supplements offer for enhanced absorption or energy support. However, for men solely focused on finding a gentle and effective iron supplement, this product more than delivers.

Like many on our list, Kirkman uses Ferrochel (a patented form of ferrous bisglycinate chelate) for better absorption and minimal gastrointestinal discomfort. Additionally, Kirkman’s commitment to quality and safety is evident through its third-party testing and in-house quality control measures. The capsules are also allergen-friendly — free of common allergens such as milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy, and sesame.

The formula’s simplicity is another highlight, as it delivers iron without unnecessary additives or complex ingredient blends. (On the other hand, some users might prefer supplements that include complementary nutrients, such as vitamin C, to support absorption further.) Ultimately, Kirkman Iron Ferrochel 5 mg is our top choice for men seeking a low-dose, high-quality iron supplement.

Pure Encapsulations also prioritizes quality and safety. “All Pure Encapsulations products undergo rigorous testing, including raw materials testing and testing for herbicides and contaminants. Products, testing procedures, and manufacturing processes are also inspected twice a year by the NSF,” explains Glinski.

OLLY Delightful Iron is the best chewable iron supplement for men on our list, due to its pleasant fruit punch flavor, adjustable dosage, and ease of use. “I’m a fan of OLLY chewable iron tablets because the dose is lower than most and can be adjusted based on how much iron a person needs,” says Andrews.

Beyond its flavor and ease of use, OLLY Delightful Iron tablets are third-party tested for quality and safety, and the brand is committed to delivering clean formulations, excluding artificial flavors and sweeteners altogether.

At 18 mg of iron in the maximum two-tablet serving, some users might find the dose insufficient if they have significant deficiencies. These tablets are also very simple and don’t offer additional nutrients to improve absorption. Similar to liquid iron, it’s important to keep these sweet-tasting supplements away from children to avoid accidental poisoning.

Despite these minor drawbacks, with its adjustable dosage, digestibility, and pleasant flavor, OLLY Delightful Iron makes taking an iron supplement easy and enjoyable.

For men seeking an iron supplement that’s easy on the wallet and the stomach, NOW Foods Iron 18 mg is our top pick for budget-friendly iron support. At just $7.14 for 120 capsules on Amazon, this supplement provides value, offering a four-month supply for less than $10.

The affordable price means that this product is straightforward and doesn’t include additional nutrients to enhance absorption. However, its simplicity and affordability make it an excellent choice for men prioritizing budget without compromising on quality.
