This invention relates to compositions for delaying aging. The compositions comprise branched-chain amino acids and whey protein, and combinations thereof, containing the same, such as L-leucine, L-isoleucine, L-valine, lactoferrin, and β-lactoglobulin. The compositions are heat stable when dissolved in water at near neutral pH. The compositions are palatable and suitable for delivering orally administrable anti-aging agents such as ω-3 fatty acids, coenzyme Q10, xanthophylls, L-arginine, and L-glutathione.
