L-carnosine

Also known as: carnosine

Carnosine is a dipeptide of beta-alanine and histidine found in muscle and brain. It acts as an acid buffer and antioxidant and is studied for protection against protein glycation.

What it is used for

  • Anti-glycation and healthy ageing support – weak evidence, mostly laboratory
  • Blood sugar metabolism support – weak evidence from small studies
  • Raising muscle carnosine – weak evidence; it is broken down in the gut, beta-alanine works better

When to take it

With or between meals, split during the day.
