The question, "Is PEScience a protein isolate?" is a common query, but the answer depends entirely on which product from their line you are referring to. The company produces both a protein blend and a pure protein isolate, each with distinct benefits and ingredients. The popular Select Protein is a blend, while ISOLATE is the 100% whey isolate option. Understanding the differences is crucial for choosing the right supplement for your dietary needs and fitness goals.
PEScience Select Protein: A Whey and Casein Blend
The product most people associate with the PEScience brand is their Select Protein. This is not a protein isolate, but rather a premium blend of whey and casein protein. The formulation is intentionally designed to deliver both fast- and slow-digesting proteins, mimicking the natural profile found in milk. Research suggests that a whey and casein blend can be superior to 100% whey for prolonged muscle protein synthesis, making it a favorite for sustained muscle building and recovery.
- Ingredients: The core ingredients include Milk Protein Isolate (containing both casein and whey) and Whey Protein Concentrate 80%.
- Benefits: The combination offers a time-release effect, helping you feel fuller for longer, which is beneficial for weight management.
- Digestibility: Thanks to the high-quality milk protein isolate, Select Protein is very low in lactose, with only about ~0.5g per serving, making it more digestion-friendly than many other blends.
PEScience ISOLATE: The 100% Whey Protein Isolate
For those with specific dietary restrictions or a preference for a purer, faster-digesting protein, PEScience created its ISOLATE product. This supplement is made exclusively with 100% whey protein isolate, with no added casein. This makes it a perfect option for individuals who have lactose intolerance or casein allergies.
- Ingredients: ISOLATE is made with 100% whey protein isolate as the sole protein source.
- Benefits: It delivers a rapid and clean protein dose, with minimal fat and carbohydrates, making it ideal for a fast post-workout recovery.
- Digestibility: The extensive filtration process removes virtually all lactose and fat, resulting in a very easy-to-digest formula.
Whey Isolate vs. Whey Concentrate: A Deeper Dive
To better understand the products, it's helpful to know the difference between the two main types of whey protein: isolate and concentrate.
| Feature | Whey Protein Isolate | Whey Protein Concentrate |
|---|---|---|
| Protein Purity | 90% or higher protein by weight. | 70–80% protein by weight. |
| Processing | Undergoes more extensive filtration to remove fat and lactose. | Less processed; retains more fat and lactose. |
| Lactose Content | Trace amounts; very low and often suitable for lactose sensitivity. | Higher lactose content than isolate; may cause issues for sensitive individuals. |
| Carbs & Fat | Minimal, making it ideal for low-carb or low-fat diets. | Higher content of carbs and fat. |
| Absorption Rate | Faster-digesting. | Slower-digesting than isolate. |
| Cost | More expensive due to additional processing. | More affordable. |
| Best For | Post-workout recovery, low-carb diets, lactose sensitivity. | General supplementation, budget-conscious consumers, slower release of amino acids. |
How to Choose the Right PEScience Protein for You
Your choice should be based on your personal health requirements and fitness goals. If you have no issues with dairy and are looking for a versatile, time-released protein blend for muscle growth and satiety, then PEScience Select Protein is an excellent option. It's also suitable for baking and adding to recipes due to its thicker texture.
However, if you are lactose intolerant, have a casein allergy, or need a clean, fast-digesting protein source with the absolute minimum carbs and fat for immediate post-workout needs, the PEScience ISOLATE is the correct choice. This product delivers pure whey protein without the casein, ensuring superior digestibility for sensitive stomachs.
Conclusion
The simple question "Is PEScience a protein isolate?" has a nuanced answer: it offers multiple products to serve different needs. The popular Select Protein is a whey and casein blend, prized for its sustained release and versatility, while the ISOLATE product is indeed a 100% whey protein isolate designed for maximum purity and fast digestion. By understanding the distinction, consumers can make an informed choice that aligns with their dietary restrictions and fitness objectives. Both products are third-party tested and offer high-quality, effective solutions for increasing protein intake, but they are not interchangeable.

By differentiating between these two product types, you can ensure you are using the best PEScience supplement for your body and goals, whether that means a fast-absorbing isolate or a slow-release casein blend.
Key Takeaways
- PEScience offers two primary protein types: The flagship Select Protein is a whey and casein blend, while ISOLATE is a 100% whey protein isolate.
- Select Protein is a slow-release blend: It combines fast-digesting whey and slow-digesting casein for sustained muscle protein synthesis and prolonged satiety.
- ISOLATE is for dairy sensitivities: It is free of casein and contains only trace amounts of lactose, making it suitable for those with dairy allergies or intolerance.
- Isolate is more processed: Due to extra filtration, ISOLATE has a higher protein concentration with less fat and carbs than the concentrate in the Select blend.
- Your choice depends on your needs: Choose Select for a versatile blend or ISOLATE for a clean, fast-digesting protein with fewer dietary triggers.
FAQs
Q: Is PEScience Select Protein lactose-free? A: No, Select Protein contains trace amounts of lactose (~0.5g per serving) but is generally well-tolerated by those with mild sensitivity due to its low quantity.
Q: Which PEScience protein is best for lactose intolerance? A: The PEScience ISOLATE is the best choice for individuals with lactose intolerance because it is formulated with 100% whey protein isolate, which contains only trace amounts of lactose.
Q: Can I use PEScience ISOLATE for baking? A: While you can use ISOLATE for baking, the thinner consistency of an isolate may affect the final texture compared to the thicker, creamier Select blend, which is often preferred for baking recipes.
Q: Does PEScience Select Protein contain casein? A: Yes, PEScience Select Protein contains casein, sourced from the milk protein isolate used in its blend. This is a key feature that distinguishes it from a pure whey isolate.
Q: Why is ISOLATE more expensive than Select Protein? A: ISOLATE is typically more expensive due to the more extensive filtration and processing required to remove fat and lactose, yielding a purer protein product.
Q: What is the primary difference in absorption speed? A: ISOLATE is faster-absorbing, providing a quick burst of amino acids post-workout, whereas Select's whey and casein blend offers both fast and slow digestion for sustained release.
Q: Is there a significant difference in amino acid profile? A: Both products offer a complete amino acid profile, including BCAAs, but the speed at which they are released and absorbed differs significantly due to their protein sources.
