Antioxidant Supplementation Reduces
Article in Current developments in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Newborns with gastrointestinal anomalies or premature birth often require lifesaving nutritional support in the form of total parenteral nutrition (TPN). However, TPN administration causes several complications in newborns. Several studies have suggested that it could be due to oxidant generation in the TPN admixture because of various factors. Objectives: This study aimed to reduce the peroxidation of the commercially available TPN for newborns by increasing concentrations of antioxidants, decreasing concentrations of prooxidants, and optimizing environmental conditions, leading to the development of a new admixture with lower oxidant load. Methods: Standard all-in-one (AIO)-TPN was used as a control diet and various antioxidants or prooxidants were supplemented above standard concentrations to determine effects on peroxide concentrations. TPNs were also exposed to light to determine environmental effects on oxidant load. Results: Peroxide concentrations in the AIO-TPN significantly increased with higher light intensity. Compared with standard AIO-TPN, AIO-TPN with a combination of L-ascorbic acid (at 2.27 mM), DL-α-tocopherol acetate (at 124.1 μM), glutathione (at 40 μM), copper (at 4.2 μM), and zinc (at 30.6 μM) in the AIO-TPN had significantly lower peroxide concentrations. The increasing combinations of vitamins C and E showed an additive effect on lowering the peroxide concentrations, whereas various combinations of copper and zinc alone did not change peroxide concentrations. Conclusions: Peroxide concentrations were significantly increased when TPN was exposed to light, but optimization using a specific combination of antioxidants significantly reduced the degree of peroxidation. Overall, this study gives novel insight into a promising strategy to develop a new TPN formula for newborns, particularly preterm infants, to decrease
