How Does Whey Protein Isolate Differ from Whey Protein Concentrate? | Whey Protein Isolate undergoes additional processing to remove most of the lactose and fat content, leaving >90% protein. Whey protein isolate is often preferred over whey protein concentrate due to its higher protein purity and reduced allergen content. |
Is Whey Protein Good for Weight Loss or just Muscle Building? | Protein is known for its satiating and thermodynamic effects, which can help reduce hunger and increase calorie expenditure. Incorporating whey protein isolate into your diet can assist in weight management by promoting fullness and an energy deficit. |
What’s in your “Natural Flavors”? | The natural flavors used in our products are derived from natural sources such as plants, fruits, or spices to enhance the taste of our products. For example, the organic compound isobutyl acetate is found in raspberries, pears, and pineapples and is used commercially to impart natural fruity flavors. Food labeling practices require the term "natural flavor" to be used instead of the specific constituents that comprise the flavoring. We prioritize using natural flavors to provide a clean and enjoyable taste experience for our customers. If you're looking for a whey protein isolate with no natural flavors, try our Unflavored option! |
Is Whey Protein Suitable for Individuals with Dietary Restrictions or Allergies? | Some flavors do contain nuts (please refer to the label for allergen warnings). We test for gluten and the main 8 FALCPA allergens in all of our products. We have an allergen segregation program and sanitize our lines after each allergen-containing production run. We are also NSF-certified on the facility level - this means that our allergen control and segregation program is approved at the highest standard possible. Note that our peanut-based flavors contain actual peanuts, so those with peanut allergies should strictly avoid these flavors. Whey isolate undergoes further processing to remove most of the lactose, making it a suitable option for those who have difficulty digesting lactose. |
Who Should Not Take Whey Protein Powder? | Individuals with a milk allergy or severe lactose intolerance should not consume whey protein powders. |
Is it Safe to Take Whey Protein Powder Every Day? | Yes, consuming whey protein powder daily is safe for most individuals. However, it's important not to rely on it as your sole source of protein. |
Is the Product Tested by Any Third-Party Organizations for Quality and Safety? | Transparent Labs Protein is certified by Informed Choice and Informed Protein for quality assurance, composition, and banned substances. We also test all of our protein with 3rd-party labs for contaminants and ingredient composition. You can find all of our latest 3rd party testing data on this page. |
Does Transparent Labs Ship to My Country? | Transparent Labs offers worldwide shipping, with a few exceptions due to import restrictions in the EU and high fraudulent activity in specific countries. Please check our shipping policy for more details. |
When Will My Order Be Shipped Out? | All orders ship out the following business day. |
Grass-Fed Whey Protein Isolate | The quality of your protein matters, and whey protein isolate is one of the purest forms of protein available. It provides a high protein content with minimal fats and carbohydrates, making it an exceptional choice for building muscle and accelerating recovery between workouts. In contrast to whey protein concentrate, whey protein isolate undergoes further filtration to remove virtually all of the lactose, making it more suitable for those who have difficulty digesting lactose. Whey protein isolate is known for its rapid absorption and ideal ratio of all nine essential amino acids (EAAs)—which includes the branched-chain amino acids (BCAAs)—necessary for stimulating muscle protein synthesis [1, 2]. In other words, whey protein isolate is about as good as it gets for kickstarting the muscle-building process after working out. By providing essential nutrients needed for muscle repair, whey protein isolate can reduce recovery time, allowing for more consistent and intense training sessions. So, why does the "grass-fed" distinction matter for whey protein powder? The vast majority of whey protein powders are made from the milk of grain-fed cows, whereas grass-fed whey protein is derived from the milk of cows that graze on natural, pesticide-free grass pastures instead of feeding on grains. Grass-feeding positively impacts the nutritional composition and quality of a cow's milk (which is subsequently used to make cheese, and "whey" is a byproduct of cheesemaking) [3]. Research has found that grass-fed whey protein boasts higher levels of bioactive whey peptides (e.g. immunoglobulins and lactoferrin), omega-3 essential fatty acids, conjugated linoleic acid (CLA), and vitamins E and A—nutrients essential for inflammation control, muscle recovery, and overall health [4]. Just as important, grass-fed whey protein isolate is free from added hormones and antibiotics that may persist in conventional dairy products [5]. |
