Micronutrients & recovery

Whey protein supplementation during marathon preparation and recovery attenuates metabolic and muscular damage (lower CK, LDH, AST, ALT) and improves post-race performance markers compared to carbohydrate-only recovery.

If you are training for a long-distance event like a marathon, take 33.5g of whey protein within 30 minutes after your long training runs. This helps reduce muscle damage markers and may help you feel better and perform better in the race.
