The details
Cross-referenced with PubMed & Examine.com
Beef protein isolate is largely collagen-derived and lower in leucine than whey; studies show it supports training gains but evidence is thinner than for whey.
Sodium is the main electrolyte lost in sweat; replacing it supports fluid balance in long or hot sessions.
