BRAND: Optimum Nutrition 100% Casein Protein Gold Standard

Brands: Optimum Nutrition.Product Categories: Vitamins & More.

Casein is a popular protein supplement for those looking for a product that is digested more slowly and provides an ongoing release of amino acids. And naturally, the industry’s top selling protein company, Optimum Nutrition (ON), has a product on the market designed to do just that.

Gold Standard 100% Casein is ON’s baseline slow-digesting protein product, and a top seller across all nutrition stores worldwide.

About casein

You might be asking why casein is a great option for supplemental protein. Casein brings all of the benefits of a general protein supplement to the table while also generating several unique benefits of its own.

The primary advantage is its slow digestion rate, making casein suitable for consumption before going to sleep or long gaps between meals. The protein congeals when passing through the digestive tract, taking the body more time to break down the thick gel and slowing absorption.

Casein is beneficial when dieting. When you’re experiencing a caloric deficit, you’re at risk of losing muscle mass. One reason this happens is because dieters tend to consume fast-digesting proteins that are absorbed quickly. The entire body utilizes the nutrients as energy, including muscles.

By consuming a protein that the body digests so slowly, a constant, moderate supply of amino acids are released over a longer period of time and sent to muscles as a priority. This was demonstrated in a study, resulting in significantly more fat loss, increased strength, and lean mass preservation in subjects undergoing a hypocaloric diet and taking either casein protein or consuming a high protein diet.[2]

What’s inside

Optimum Nutrition keeps the ingredient list short and simple as the ‘100% Casein’ name suggests. Micellar casein, at the top of the list, is followed by the usual blend of flavoring agents and sweeteners. Their 100% Casein product contains 24g of protein, 3g of carbohydrates, and 1g of fat per serving. This is a significantly higher percentage of calories from protein than many competitors’ products, who tend to reduce costs by using lower quality protein sources or use cheap carbohydrates.

Perhaps the most noteworthy thing is something most people won’t even notice. Optimum Nutrition’s 100% Casein increases absorption by adding Aminogen, a patented digestive enzyme blend that has been shown to dramatically increase amino acid bioavailability from protein sources.[1]

Flavor and texture

Banana creamThe days of chalky protein supplements are gone, Optimum Nutrition 100% Casein is available in five flavors:

  • Chocolate peanut butter
  • Chocolate supreme
  • Cookies and cream
  • Creamy vanilla

All have received positive reviews from consumers, overall. The only criticism sometimes levied at the flavoring is that

How to usethey can be too mellow and not bold enough.

Take one to two scoops per day, either before bed or during any during long gaps between meals.

Side effects

Casein is generally well tolerated, but as with all supplements you

should talk to your doctor before beginning supplementation, particularly if you are sensitive to dairy.
