Lutein vs. Leucine for vision?

Lutein is beneficial for vision, particularly in preventing or mitigating vision loss due to conditions like age-related macular degeneration. It is often used as a supplement specifically for enhancing eye health 1.

Leucine, on the other hand, is an amino acid that does not have a direct connection to vision improvement. It is primarily known for its role in muscle building and recovery. There was a clarification made by Andrew Huberman after misspeaking in a previous context, where he corrected the confusion between lutein for vision and leucine for muscular benefits 1.

Therefore, for vision health, lutein is the appropriate choice, not leucine.
