My latest labs show my iron is 31 (reference range

Patient: My latest labs show my iron is 31 (reference range is 59-158). My Hgb is 10.2 (14.0-18.0). My RBC is 3.27 (4.7-6.10). I take 65 mg of iron (equal to 325 Ferrous Sulfate). Is boosting that to three 65 mg iron tablets a day worth a try to improving iron numbers, Hgb and RBC?I had 5 bypasses 5 months ago. Trying to regain strength and having anemia issues.
