However, different whey protein types vary in processing methods, nutritional content, and quality. Whey protein concentrate and isolate are the two most common forms of whey protein, with concentrate being the less processed and isolate being the more processed.
In this opportuniteas whey protein review, we will compare Grass Fed Whey Protein Concentrate and Isolate, two high-quality products that offer grass-fed, unflavored, and non-GMO whey protein. We will look at their similarities and differences, pros and cons, specifications and features, flavors available on the market, and the number of reviews on Amazon with average ratings, and we will decide which one is better for you.
Similarities Between Opportuniteas Whey Protein Concentrate and Isolate
Concentrate and Isolate have standard features that make them excellent choices for whey protein supplements. Here are some of the similarities between them:
- Grass-fed: Both products are sourced from grass-fed cows raised without hormones, antibiotics, or GMOs. Grass-fed whey protein has higher omega-3 fatty acids, conjugated linoleic acid (CLA), and antioxidants than conventional whey protein. These nutrients have anti-inflammatory, immune-boosting, and fat-burning benefits.
- Unflavored: Both products are unflavored and have no added sugar, sweeteners, preservatives, colors, or flavors. It makes them ideal for people who don’t like flavored protein powders or want to avoid artificial ingredients. Unflavored whey protein is easy to mix with almost any drink or recipe, such as smoothies, oatmeal, coffee, or baked goods.
- Non-GMO: Both products are certified non-GMO by the Non-GMO Project Verified seal. It means they are produced without genetically modified organisms that may adversely affect health and the environment.
- High-quality: Both products are made with high-quality whey protein tested for purity and potency by third-party labs. They are also manufactured in a GMP-certified facility that follows strict quality standards.
Differences Between Concentrate and Isolate
While Opportuniteas Whey Protein Concentrate and Isolate share some standard features, they also have some significant differences that may affect your choice depending on your goals and preferences. Here are some of the differences between them:
- Processing: Whey protein concentrate removes most water, fat, and carbohydrates from the liquid whey and has about 80% protein by weight. Whey protein isolate is processed more to reduce fat and carbohydrates further from whey protein concentrate. It has 90% or more protein by weight.
- Protein content: Due to the different processing methods, protein isolate has a higher protein content per serving than whey protein concentrate. For example, a 120-calorie serving of Opportuniteas Grass Fed Whey Protein Isolate provides 28 grams of protein, while a 120-calorie serving of Opportuniteas Grass Fed Whey Protein Concentrate provides 24 grams of protein.
- Fat and carbohydrate content: Due to the different processing methods, whey protein isolate has a lower fat and carbohydrate content per serving than whey protein concentrate. For example, a 100-calorie serving of Opportuniteas Grass Fed Whey Protein Powder Isolate has 0 grams of fat and a gram of carbs (0 grams of sugar). In comparison, a 100-calorie serving of Opportuniteas Whey Protein Concentrate has 1 gram of fat and 3 grams of carbohydrate (2 grams of sugar).
- Lactose content: Due to the different processing methods, whey protein isolate has a lower lactose content than whey protein concentrate. Lactose may cause digestive issues for some people who are lactose intolerant or sensitive. Whey protein isolate has less than 1% lactose, while whey protein concentrate has about 4%.
- Price: The different processing methods make whey protein isolate more expensive. But at times, due to discounts on Isolate, its price is almost at par with concentrate. For example, a 1-pound bag of Opportuniteas Grass-Fed Whey Protein Isolate costs $30.79 ($1.92 per ounce), while a 1-pound pack of Opportuniteas Whey Protein Concentrate costs $29.99 ($1.87 per ounce).
