Whey protein supplementation significantly reduces interleukin-6 (IL-6) and increases insulin-like growth factor-1 (IGF-1) and albumin levels in older adults with sarcopenia.

Whey protein supplementation not only helps with muscle mass but also improves key biochemical markers in older adults with sarcopenia. It significantly reduces inflammation (IL-6) and increases beneficial hormones (IGF-1) and proteins (albumin). This suggests broader health benefits beyond just muscle size.
