FIGURE 2 A recent in vitro reconstitution of the complete ISC machinery performed in our laboratory using recombinant mouse proteins has shed new light on the mechanism of Fe-S cluster biosynthesis and the functional role of FXN (Figure 2B, blue chart) (Parent et al., 2015

Key Takeaway Sulphur-rich foods, S-Acetyl Glutathione and N-Acetyl L-Cysteine (NAC) may help support healthy glutathione levels by either providing glutathione directly or supplying the building blocks required for its production
