Optimum Nutrition is the name of an Illinois-based fitness supplement company. The business was founded in 1986 by two brothers with extensive bodybuilding experience. Together, Tony and Michael Costello formed what was once called Costello’s Health Distributors.

Over a few years, the brothers realized that there was a significant need for quality products and an innovative vision within their industry. They seized this opportunity by transforming Costello’s Health Distributors into the Optimum Nutrition brand you know today. Their goal was to create a brand that would satisfy the fitness industry’s need for premium-quality products that change the fitness performance world. Simply put, they wanted to create a new gold standard, and that’s precisely what they did.

The brand’s most popular product is aptly named “Gold Standard 100% Whey,” and it has remained their best seller for years. The Costello brothers enjoyed 22 years of success with the product and their brand as a whole. However, they ultimately felt it was best for the brand to grow even more, so they entered into an agreement that would make Optimum Nutrition part of a global nutrition group called Glanbia.

Today, you can find over 50 different sports nutrition products manufactured by Optimum Nutrition. You can choose to shop by product type or goal, which means you can find something for:

  • Preparing to Train
  • Powering Through Training
  • Recovery
  • Weight Gain
  • Strength & Endurance

With all of that said, you might be wondering, “is Optimum Nutrition good? Are they a reputable brand despite their growth?” The answer to both of those questions is yes! Even when a global nutrition group acquired the brand, the company's integrity did not change. The company’s long track record of providing premium products with high standards continues.

If anything, the company has become even more committed to innovation and quality control. To this day, it is just one of a few sports nutrition companies to manufacture its own products. You can find their state-of-the-art facilities in Middlesbrough, UK. This is where they currently manufacture every one of their different product categories, from shakes and powders to snacks and vitamins.

Want to know what we love most about this brand?

They go above and beyond with every step of the manufacturing process so that you can expect nothing less than the following:

Premium Raw Materials

The Optimum Nutrition brand never compromises on quality, so they only start with the very best raw materials. Before they begin a single manufacturing process, they go out of their way to source ingredients with a Certificate of Analysis. Even with that certificate, Optimum Nutrition takes steps to verify compliance for all ingredients by testing not once but twice!

Innovative Manufacturing Processes

For more than three decades, Optimum Nutrition has always worked to maintain the highest standards of quality with its state-of-the-art manufacturing processes. Their hands-on approach leads to daily inspections for quality assurance. These inspections ensure that all facilities are compliant with Good Manufacturing Practices. Their manufacturing plant is also registered as an Informed Sport and Informed Choice facility, and they have earned a Grade A BRC food certificate.

Complete Customer Satisfaction

One of the reasons that customers continue to choose this brand is its commitment to customer satisfaction. Their strict selection of ingredients, thorough testing, and quality-controlled manufacturing processes are all done for one reason—to provide you with the best sports nutrition products on the market. When the company was founded more than 30 years ago, the mission was to bring products with consistent quality. Still, to this day, they continue to work on setting even higher standards for the industry and themselves.

Industry-Leading Products

Optimum Nutrition is never complacent when it comes to developing products. The brand is continuously striving to make improvements through innovation. They are leading the way in many different product categories. Not only have they dominated the whey protein world, but they have also created a slow digesting protein category with their Gold Standard 100% Casein powders.

whey protein isolate - Vitasave Canada

At Optimum Nutrition, the majority of protein products feature 100% whey. However, they also have 100% casein products. To understand what that means, you must know where these types of proteins come from.

Dairy milk contains whey and casein protein, so the majority of whey protein powder is a byproduct of cheesemaking. When cheese manufacturers add a coagulant to milk, it forces the whey to separate from curds, which are made of casein.

The whey can then be processed through different techniques to achieve a variety of products. Powders are typically made into:

  • Whey Protein Concentrate (WPC)
  • Whey Protein Isolate (WPI)
  • Hydrolyzed Whey Protein
  • Whey Peptides

Most protein powders on the market use Whey Protein Concentrates, but the protein content can range from 34-80%. While this might be great for some people, others might prefer something with fewer calories, carbs, and fats. That’s where WPI comes in. This protein goes through a filtration process to remove more of the fat, carbs, lactose, and cholesterol that was left over. As a result, you get a powder that is up to 90% protein.

Optimum Nutrition’s Gold Standard 100% Whey products are primarily made with WPI. However, you’ll also find WPC and some hydrolyzed whey protein. Below are some of the most popular ON® Gold Standard Flavors:

  • Extreme Milk Chocolate
  • Vanilla Ice Cream
  • Chocolate Peanut Butter
  • Double Rich Chocolate
  • White Chocolate
  • Rocky Road
  • Cookies & Cream
  • French Vanilla Creme
  • Chocolate Coconut
  • Chocolate Malt
  • Mocha Cappuccino

For those who are interested in a plant-based option, you’ll be happy to know that Optimum Nutrition also creates a Gold Standard 100% Plant powder. It is made with a protein blend of:

  • Organic Pea Protein
  • Organic Brown Rice Protein
  • Organic Sacha Inchi Protein

For years, Gold Standard 100 Whey Protein has been one of the most popular choices for athletes looking for muscle-building improvement. It has garnered worldwide attention from its users because of the quality of the formula and the ingredients used in it. If you are shopping around for other alternatives, you will have a hard time finding a product that offers more value to its consumers.

The following are just a few of the benefits that you can expect to receive when you add Gold Standard Whey Protein to your health and fitness regimen:

  • The formula for Optimum Nutrition protein powder contains 100% pure protein.
  • It provides you with 24 grams of protein and just one gram of fat.
  • Gold Standard also provides you with over 5 grams of amino acids to help your muscle tissues repair.
  • Optimum Nutrition designed the powder specifically to help athletes develop large, strong muscles. It’s beneficial for developing a muscular physique.
  • The whey protein isolates used in the formula consist of double-purified protein, so you don’t have to worry about adding unnecessary carbohydrates.
  • When compared to other whey proteins with the same quantity and quality of ingredients, the Gold Standard is more affordable.

Optimum Nutrition provides instructions for all their protein powders, but there is very little difference from what you would expect with any other powder. You can simply mix one rounded scoop of powder with approximately six to eight ounces of liquid. They recommend that you use cold water, but you can also use milk or another beverage of your choosing.

If you want to get the most out of your shake, they suggest that you mix your shake anywhere from 30 to 60 minutes following your workout. However, you may also use the drink as a snack to supplement a balanced diet with more protein. It is not recommended to use Optimum Nutrition protein shakes as your sole source of protein. Instead, you should maintain your daily protein intake with a combination of high protein foods and supplements throughout the day.

Gold Standard 100 Whey Protein isn’t the only product that Optimum Nutrition has to offer. They have various fitness and nutrition-related products to help you achieve your goals. Keep reading to learn more about other popular products you can choose from.

Essential Amino Energy

Amino acids are great for rebuilding your muscles after a challenging workout, and caffeine is perfect for providing your body with post-workout energy to make it home from the gym. Customers love the Optimum Nutrition Amino Energy supplement because the high-quality product provides your body with the perfect blend of essential amino acids and energy.

Specifically, Amino Energy uses branched-chain amino acids (BCAAs). These are a critical part of muscle restoration, and they help you to absorb your amino acids faster. A quick increase in BCAA even prevents your muscles from breaking down when you lack nutrients.

Want to know more reasons for loving this post-workout supplement?

It is low in both calories and carbohydrates, and Optimum Nutrition only uses natural sources of caffeine. When you combine the amino acids with caffeine, you can not only improve your endurance but can also improve your overall athletic performance. This product can even be a great morning wakeup in place of your standard cup of coffee, or you can use it as a pre-workout.

Protein Wafers

Are you struggling to hit your daily required protein intake? If so, you might want to consider adding Optimum Nutrition's Protein Wafers to your diet and exercise program. These 2-wafer servings have 15 grams of protein, and they are the perfect snack in between meals. We especially appreciate their on-the-go convenience for busy schedules.

We think that you’ll also be pleased with the taste of these products. While some protein bars are less than enjoyable, these bars will give you all the flavor you’d expect from a cheat meal. Our personal favorite flavor is the Vanilla Crème!

Micronized Creatine Powders

While Optimum Nutrition also offers Gold Standard Creatine, we want to highlight their Micronized Creatine Powder. Over the years, extensive studies have been done to show the benefits of creatine monohydrate. These benefits include support for your muscle size, muscle recovery, and strength when this creatine powder is used consistently.

Since this particular product is micronized, you can enjoy easier shaker cup mixing. It also contains five grams of 100% pure creatine monohydrate per serving. It’s vital that you consume this product as part of a balanced, healthy diet and exercise regimen.

Serious Mass

If your goal is to gain both weight and muscle, then we think that you will love Optimum Nutrition’s Serious Mass line. These products come in several enjoyable flavors, but no matter which you prefer, you’ll get the same benefits. All of these supplements feature 50 grams of protein and 150 grams of carbohydrates. In just two scoops, you can get nearly 1,300 calories!

That’s not all.

They also pack in 25 different vitamins and minerals to help your overall health and wellness. There are no fillers or added sugars, just natural and artificial flavors—depending on the flavor you prefer. This weight-gaining supplement in its purest form is perfect for anyone looking to gain more mass and size without any banned substances.
