Optimum Nutrition 100% Casein contains 32g of slow digesting casein protein with very little carbohydrate (3g) or fat (0.5g). The advantage of casein over whey protein is that it can take up to 1.5-2x longer to digest, resulting in a slower more sustained release of amino acids. This may help reduce feelings of hunger and be ideal to take before bed where your goal should be to maintain the availability of protein for as long as possible, too reduce catabolism through the night.
The inclusion of BCAAs may aid muscle gain further than that of protein alone as some studies have indicated that they reduce muscle breakdown and muscle soreness after exercise.
Optimum Nutrition 100% Casein also contains glutamine, but there is no evidence that supplementation of L-glutamine will improve muscle recovery or gains in size and strength beyond that of protein alone.
This supplement contains Aminogen, an enzyme involved in protein digestion which has been shown to increase the rate at which protein is absorbed, which might seem slightly contradictory given the main feature of casein over whey protein is the longer digestion times.
- Contains 32g of casein protein, which is slower digesting than whey protein, making it ideal as a snack between meals or to take before bed.
- BCAAs may help reduce protein breakdown and muscle soreness after resistance training.
- Contains Aminogen, which may speed up protein digestion, but this would be contradictory to the goals of this supplement.
Who’s it for
Optimum Nutrition 100% Casein is ideal for someone doing regular resistance training who want snack high in slow digesting protein, low in fat and carbohydrate for between meals or before bed. This supplement is not ideal for pre and post workout nutrition.
