Product description
Slow-Digesting Protein for Overnight Recovery
Casein, a slower digesting and absorbing protein can be used after exercise, between meals or before bed to help support satiety and muscle recovery. Gold Standard 100% Caseinā„¢ delivers BCAAs to recovering muscles for several hours. By using only premium micellar casein as a protein source, we’ve created a protein powder that sets the Gold StandardĀ® for slow digesting protein support.
Benefits
Ā·24 Grams of Protein per Serving
Ā·Nearly 5 Grams of Naturally Occurring BCAAs per Serving to Support Endurance and Recovery
Ā·Ideal for Use Between Meals and Before Bed
Ā·40% of the Daily Value for Calcium per Serving
Ā·110-120 Calories per Serving
Ā·0.5-1 Gram of Fat per Serving
Ā·1 Gram of Sugar per Serving
Suggested Use
Mix a scoop of the powder into 8 to 14 fluid ounces of cold water or milk using a shaker cup. For best results, mix up your shake 30 to 60 minutes after your workout, before bed, or use as an anytime snack.
For healthy adults, consume enough protein to meet your daily protein requirements with a combination of high protein foods and protein supplements throughout the day as part of a balanced diet and exercise program

I am on a juice only diet, so I need good protein so my muscles can rebuild and recover quickly.  Optimum nutrition is by far the best protein I’ve ever had and I’ve stuck with them for about 10+ years.  I do whey & isolate during the day and casein before bed.  My diet only contains 14 g of protein a day so I need a lot of protein since I am working out a lot at the gym #Protein #MuscleRecovery #Bodybuilding #OptimumNutrition #TikTokShopCreatorPicks

What is the difference between Whey and Casein protein? Whey is fast acting and I will do it during the day.  Casein is slower release and that is what I will do before bed.  #ProteinPowder #OptimumNutrition #QuickActingProtein #LongLastingProtein #TikTokShopCraterPicks

I find that if I have got a low protein intake that it takes a lot longer for my muscle recovery which basically means my muscles are sore for a very long time.  I use isolate & whey during the day and casein right before bed for that nice slow release of protein.  I’ve been using optimum nutrition for decades. This truly is the gold standard of protein.  #ProteinIntake #MuscleRecovery #WorkingOut #NighttimeRoutine #TikTokShopCreatorPicks

I started working out again, and I am finally getting some results.  The optimum nutrition way products have been a major game changer for me.   I have been eating a more vegetable diet with less protein.  My muscles have been hurting and taking a toll so I am using the protein drinks to supplement and give my muscles the food they need to grow. #Workout #Gym #MuscleRecovery #TikTokShopCreatorPicks

I find that when I work out hard and take protein shakes my muscle recovery is a lot faster and my gains are a lot better.  If you were going to be increasing your workouts, be sure to check out increasing your daily protein intake with some high-quality protein to aid in the recovery and growth of your muscles.  #OptimumNutrition #ProteinShake #MuscleRecovery #GymWorkoutRoutine #TikTokShopCreatorPicks

My current diet only gives me 14 g of protein a day.  That means my muscles would be in constant pain from working out recovery times would be super long.  My body needs protein to rebuild those muscles so how do I get it?  Well the gold standard, of course optimum nutrition.  #Workout #Protein #OptimumNutrition #GymWorkout #TikTokShopCreatorPicks
