The best iron supplements for increasing ferritin levels include iron bisglycinate and heme iron, each offering unique benefits.

• Iron Bisglycinate: This chelated form of iron is known for its high bioavailability and gentle effect on the stomach.
• Heme Iron: Derived from animal sources, heme iron is more efficiently absorbed by the body compared to non-heme iron forms.

Iron Bisglycinate: Iron bisglycinate is a compound where iron is bound to the amino acid glycine. This binding enhances its absorption in the intestines and reduces gastrointestinal side effects such as constipation and nausea, which are common with other iron supplements. Its high bioavailability means that a smaller dosage can be effective, making it a convenient choice for individuals looking to increase ferritin levels without discomfort.

Heme Iron: Heme iron is found in hemoglobin and myoglobin, primarily in red meat, poultry, and fish. It is absorbed more efficiently than non-heme iron, with studies showing that the body can absorb 15-35% of heme iron compared to only 2-20% of non-heme iron. This efficiency makes heme iron a potent option for quickly raising ferritin levels, especially in individuals with iron deficiency anemia.

What Factors Should You Consider When Choosing an Iron Supplement for Ferritin?
