I said lutein, and lutein was the correct thing to say, but once or twice, when I started speaking fast I said leucine and not lutein. I want to emphasize that leucine, an amino acid, very interesting, important for muscle building covered in previous episodes, but lutein, L-U-T-E-I-N, is the molecule and compound that I was referring to in terms of supplementing for sake of vision.
