Optimum Nutrition Gold Standard 100% Casein

Optimum Gold Standard 100% Casein is pure casein protein powder. It is great for daily snacks and especially for bed time shakes due to slow digestion. Main ingredient is micellar casein.

Macronutrient content varies among flavors due to added sweeteners and flavors (for example, cocoa where chocolate flavor is wanted). Also, there is slight variation in content of used raw materials, but that can be ignored, of course.

Macronutrient content, per 100g of powder, is given in following table:

Flavor	Amounts in grams per 100g of powder
	Protein	Carbs	Fats	Fibers
Banana Cream	75	9	3	3
Blueberry & cream	75	9	3	3
Chocolate cake batter	72	12	3	3
Natural - Chocolate Cream	64	21	4	3
Chocolate peanut butter	72	12	3	3
Chocolate Supreme	73	9	3	3
Cookies & Cream	75	9	3	3
Creamy Vanilla	75	9	3	3
Natural - French Vanilla	66	22	3	3
Mint Chocolate Chip	75	12	3	3
Raspberry Smoothie	75	9	3	3
Strawberry Cream	75	12	3	3

Natural flavors (Chocolate Cream and French Vanilla) contain less protein and more carbs when compared with other flavors, but they don't contain artificial flavors or sweeteners.

Optimum Gold Standard 100% Casein comes in 2 and 4 lbs containers. Also, if you want to try a flavor or need smaller package for a trip or anything similar, Optimum casein can be found in very convenient 3 packets packages.

Thanks to added lecithin, which helps with mixability, Optimum casein mixes very well in the common shaker or even in the glass with the spoon.

Powder gives thick texture to the shake, with no lumps and very little foam, even when mixed with cold water. Thickness can be varied by changing the amount or type of added liquids - great as Meal Replacement Powder.

Taste differ from flavor to flavor. People who like chocolate taste will prefer chocolate flavors, while other may like fruity flavors. Creamy Vanilla is great for fruit smoothies and shakes. Cookies & Cream flavor is OK for most of the trainees.

With so many flavors, it is good to find some sample packs and give them a try. If you are unable to find them, go with Chocolate Supreme or Cookies & Cream.

Optimum Gold Standard 100% Casein is great bedtime protein powder. It can also be used in shakes and smoothies during the day. It is not so good around workouts, where faster digesting protein is needed.

Chocolate flavors make a delicacy when mixed with peanut butter, low-fat or cottage cheese, and various nuts. Fruity flavors can be mixed with various fruits (my favorites are various types of berries) and low-fat and cottage cheese.

During summer, refrigerated smoothies have taste and consistency of ice creams. And they are guilt-free, even if you are on a serious diet :)

If you consider going for a liquid diet (very effective, but not the healthiest diets around - IMHO, must be under doctor's supervision) , then this protein powder, with so many flavors, is one of the powders you should base your diet on - with other casein powders, but also with egg protein, milk protein isolate and whey protein powders or even some plant based protein powders (especially ones with greens).

Note that there are casein powders with less carbs and fats and more protein per gram of powder, but Optimum Nutrition 100% Casein Powder has great taste, mixability is excellent and it is very easy on the stomach.

Price of this protein powder is ok on sale - there are casein powders that are little bit cheaper, but with this protein powder you know what you are buying. After all, it is for many reasons one of the most popular casein protein supplements for many years.

Optimum Gold Standard 100% Casein protein powder - highly recommended for anyone needing good, high quality casein protein powder at acceptable price.
