Can acetyl glutathione be taken with food?

S-acetyl-glutathione can be taken with or without food. The absorption should not be affected either way. I have no research supporting it crossing the blood brain barrier. S-Acetyl Glutathione (S-A-GSH) is a unique form of glutathione. with an acetyl group (COCH3) attached to the sulfur atom of cysteine in the glutathione molecule. S-A-GSH is ideal for oral ingestion, because this acetyl group protects glutathione from breaking down in the gastrointestinal tract; once absorbed and inside the cells it is removed, thus leaving the glutathione molecule intact.
