Optimum Nutrition 100% Natural Casein Protein 2 Pounds

We all know the benefits of Micellar casein especially before bed or in the morning to ensure that we are providing our muscles with amino acids to stay probolic and stay out of the dreaded catabolic zone. Unfortunately if you’re trying to get a quality Micellar casein you have to suffer through a barrage of artificial flavorings, colors & sweeteners. Sweetened with all natural sweeteners with a great taste and no chemical after taste. So if you’re looking for a truly pure Micellar casein protein with no additives than Optimum Natural Casein is for you!

ON Natural Casein Benefits

  • Micellar Casein
  • 24 grams of time-released protein
  • Aminogen Digestive Enzymes
  • 5 Grams of BCAAs
  • 5 Grams Glutamine Precursors
  • Naturally Sweetened


Optimum Nutrition 100% Casein Reviews


Little gritty but overall not bad. Love it if I'm not going to eat for awhile or before bed.


Mixes so well and tastes even better. Take it every nite before bed and really helps me reach my goals. All flavors are great and I like to mix it up.


Great late night protein that contains 100% casein protein which is a very slow absorption protein designed to carry you through your nightly fast. If you don't think you need a night protein and you want to compete or keep a good constant physique then ask me why you do need Casein. Optimal Nutrition does not use Sucralose, but instead uses Stevia as their sweetner in its Natural line of products, a huge plus for me.



Micellar Casein, Natural Flavor, Honey Powder, Inulin, Evaporated Cane Juice, Salt, Cellulose Gum, Lecithin.


Add one rounded scoop of 100% Casein Protein to 10-12 oz of water, milk, or your favorite beverage.

    Average Casein Protein

    I would say that this is an average product. I'm not a big fan of Optimum products, but this one is okay. I do like their casein products. Because it is slower digesting than whey, I would suggest taking it as a meal replacement or as I took it, right before bed. It's a little thicker than other proteins so it tastes better.
