Gold Standard 100% Casein
每份一勺含24g的酪蛋白.富含反分解代謝的酪蛋白.每份超過9克支鏈氨基酸,谷氨酰胺. 僅含低至3-4g的碳水化合物,低碳水化合物,慢速吸收,反分解代謝.
酪蛋白是從牛奶中提煉出來的消化吸收時間較長的蛋白,具有抗肌肉蛋白分解的能力,它含有21種氨基酸,高營養,低脂肪,低膽固醇,以及多種牛奶生物活性微粒.
酪蛋白對酸鹼值敏感,在胃酸的酸性環境裡會成為膠狀.為此酪蛋白與乳清和其它蛋白質相比需要花兩倍甚至更多的時間方能分解成為氨基酸.因為它隨時間逐漸緩慢釋放成分的特性,因此酪蛋白又被形容為反分解代謝的,保護肌肉的蛋白質.
由於酪蛋白消化吸收時間較長,可以在食用後長時間維持體內氨基酸和谷氨酰胺水平,強大的抗分解能力可以防止肌肉蛋白的損耗.另外酪蛋白抗肽鍵分解,延緩飢餓,能增加飽腹感,促進脂肪的分解.
緩釋酪蛋白有別於乳清蛋白或其它種類蛋白,它能夠加長並延遲吸吸使間,令身體慢慢吸收蛋白.在做健身前後,身體需要快速地吸收蛋白質.不過在其餘時間,慢慢吸收蛋白質是最理想的此為酪蛋白的特性.尤其在睡前最為適合.
Optimum Nutrition's Gold Standard 100% Casein is an ultrapure form of micellar casein protein. Each serving provides a huge serving of muscle-building casein protein with hardly any calories from fat or carbohydrates. Casein is a favorite of both gainers and dieters for its anabolic effects on muscle growth throughout gaining phases and preservation of muscle during dieting phases.
Casein and whey are both derived from milk protein, and each is absorbed and utilized in an entirely different manner. Whey is broken down and absorbed rather quickly offers consumption while casein forms a viscous gel in the digestive tract, allowing the component amino acids to be absorbed over a much longer period.
Whey is usually taken immediately after a workout to take advantage of its fast absorption while casein is typically taken during other times, especially at night or a couple of hours before a planned workout. This allows amino acids to be delivered during and after workouts and also while you are asleep, ensuring optimal nitrogen retention in muscles during these important times of recovery.
