However, when intracellular iron ions are overloaded, Fe 2+ can catalyze the generation of metabolically toxic reactive oxygen species and phospholipid peroxide through the Fenton reaction, leading to cell damage or death (Ingold et al., 2018) (Figure 4)

Unlike some vitamins, B12 can be stored in the liver for an extended period, sometimes taking years for a deficiency to manifest
We are thus left with poorly studied experimental drugs referred to as peptides, although some are not, sold for research use only, though clearly meant for human consumption, to gain a wide array of physical benefits that are unlikely to manifest
The second most abundant dietary source is SeCys, while selenate and selenite represent the major inorganic sources, ingested mostly through water or supplements, less through plants and animals (e.g., fish), and contribute less to the daily dietary intakes (45, 57)
