This was reviewed and discussed in this article.
Based on meta-analyses showing hemoglobin improvements of 2.01-5.30 g/dL in iron deficient populations. Higher doses show diminishing returns with increased GI side effects. Effectiveness varies significantly by baseline iron status and form used.
Based on single RCT (n=37) showing 25.6% glucose reduction when tea consumed with sucrose. Conservative estimate due to limited study population and single trial. Effect may be specific to tea preparation and timing with carbohydrate intake.
