You need copper for proper glutathione function.

b3 copper glutathione retinol vitamin a

Yup, glutathione peroxidase (GPO) — a glutathione metabolizing enzyme — is a function of ceruloplasmin, that very important copper protein I talk about a lot.
*
GPO is important for:
*
〰️Converting reactive oxygen molecules aka peroxides like hydrogen peroxide (H2O2) into water
〰️Protecting cell membranes and blood vessel linings
〰️Preventing cellular degeneration
〰️Red blood cell metabolism
〰️Preventing chromosomal damage
*
Many people today supplement glutathione, but most don’t realize that they won’t make it past their stomach acid (hello expensive pee).
*
If we’re not making enough GPO, we’re probably deficient in copper. We also need Vitamin B3 and cysteine.
*
Where to go from here?
*
〰️Eat copper-rich foods (see my “Copper-Rich Foods” post)
〰️Eat retinol-rich foods (see my “Beta Carotene is NOT Real Vitamin A” post)
〰️Eat B3-rich foods like beef and fish
〰️Eat cysteine-rich foods like eggs, dairy and poultry
〰️Save your money on those glutathione supplements
