Syn-Coll- Summary
- Glutathione is the body's master endogenous antioxidant tripeptide, composed of glutamate, cysteine, and glycine. It neutralizes reactive oxygen species, supports detoxification in the liver, recycles other antioxidants (vitamins C and E), and plays a central role in immune function, DNA repair, and cellular redox balance.
- Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.

- Complementary to retinoids or vitamin C
- Side Effects
- Oral bioavailability is limited (largely hydrolyzed in gut); liposomal or sublingual forms preferred
- IV administration: rare allergic reactions, vein irritation
- High-dose supplementation may cause zinc depletion over time
- Inhaled glutathione may trigger bronchoconstriction in asthmatics
- Generally well-tolerated
- Rare mild irritation at high concentrations
- Possible sensitivity in individuals with inflammatory skin conditions
