Green tea extract supplementation increases serum Zinc and Magnesium levels while decreasing Iron levels in obese patients, thereby improving total antioxidant status.
Green tea extract supplementation improves your body's antioxidant status and increases Zinc and Magnesium, which are often low in obesity. However, it also lowers Iron levels. If you are prone to anemia, monitor your iron status, as green tea may reduce iron absorption.
GoodSupportsHIGH confidence
Increases in total antioxidant level and in zinc concentration in serum were also observed. Glucose and iron levels were lower in the green tea extract group than in the control...
Why this rating
Same RCT design as N1, with specific biochemical assays for minerals.
