3 min read

Scientific research shows that a complete protein contains all nine essential amino acids, which the human body cannot produce on its own. Both Ascent’s whey and plant-based protein powders are formulated to be complete proteins, supporting muscle repair and growth.

Quick Summary

Both Ascent's whey and plant protein products are confirmed to be complete proteins, containing all nine essential amino acids necessary for muscle repair.

Key Points

Both Formulas are Complete: Both Ascent's whey and plant-based protein powders contain all nine essential amino acids.
Whey is Naturally Complete: Ascent's whey protein, being dairy-based, is an inherently complete protein source.
Plant Protein is a Strategic Blend: The plant-based powder achieves a complete amino acid profile by blending organic pea, sunflower, and pumpkin proteins.
Contains Muscle-Supporting Nutrients: Both versions include high levels of BCAAs, including leucine, which is critical for muscle synthesis.
Ideal for Recovery: The complete amino acid profiles in both protein powders make them effective for muscle repair and recovery after workouts.
Caters to Dietary Needs: Ascent provides a high-quality, complete protein option for both dairy-consuming and vegan athletes.

What Makes a Protein 'Complete'?

A protein is considered "complete" when it contains all nine essential amino acids (EAAs). These are amino acids that our bodies cannot synthesize and must be obtained through our diet. For athletes and active individuals, consuming a complete protein is crucial for optimal muscle protein synthesis and recovery. The nine essential amino acids are:

Histidine
Isoleucine
Leucine
Lysine
Methionine
Phenylalanine
Threonine
Tryptophan
Valine

Proteins from animal sources, like meat, eggs, and dairy, are naturally complete. However, many individual plant protein sources are "incomplete," meaning they are low in or missing one or more EAAs. To create a complete plant-based protein, different sources are strategically blended together.

Is Ascent Whey Protein a Complete Protein?

Yes, Ascent's whey protein powder is a complete protein. As a dairy-based product, whey naturally contains all nine essential amino acids in concentrations that are highly bioavailable for the body. Ascent’s whey protein is made from a blend of native whey protein isolate, standard whey protein isolate, and whey protein concentrate. Native whey, filtered directly from high-quality milk, is a less-processed form that retains higher levels of naturally occurring leucine, a key amino acid for initiating muscle protein synthesis. Each scoop delivers 25g of protein and a robust profile of amino acids, including more than 5g of naturally occurring branched-chain amino acids (BCAAs).

Is Ascent Plant Protein a Complete Protein?

Yes, Ascent's plant protein is also a complete protein. To achieve a full amino acid profile, Ascent utilizes a specific blend of complementary plant-based protein sources. Their formula combines:

Organic pea protein
Organic sunflower protein
Organic pumpkin protein

Pea protein is typically lower in the amino acid methionine, while sunflower and pumpkin proteins are higher in this amino acid. By combining these specific sources, Ascent ensures the final product contains all nine essential amino acids in sufficient quantities to be classified as complete. The result is a vegan-friendly, dairy-free, and certified gluten-free option that supports muscle health and recovery effectively.

How Ascent Creates a Complete Plant-Based Profile

Creating a complete plant protein blend is a key aspect of modern vegan nutrition. Unlike a single source like rice protein, which can be low in certain amino acids, a blend ensures all bases are covered. This combination approach allows the strengths of each ingredient to compensate for the weaknesses of others, resulting in a nutritional profile comparable to animal-based proteins. By carefully formulating their plant-based powder, Ascent provides an alternative that doesn't sacrifice protein quality for dietary preference.

Whey vs. Plant-Based Protein: A Comparative Look

When choosing between Ascent's whey and plant protein, several factors come into play. While both are complete proteins, their sources and properties differ.


Feature	Ascent Whey Protein	Ascent Plant Protein
Source	Dairy (Native Whey, Whey Isolate, Whey Concentrate)	Organic Plant Blend (Pea, Sunflower, Pumpkin)
Complete Protein?	Yes, naturally	Yes, via complementary blend
Allergens	Contains milk. Produced on equipment that may process tree nuts & peanuts.	Free of dairy, soy, and gluten. Produced on equipment that may process tree nuts & peanuts.
Digestion Speed	Rapidly digesting and absorbing, ideal post-workout.	Slower digestion than whey, which can increase satiety.
Taste & Texture	Generally smoother and creamier.	Texture has been improved over time, but can sometimes have an earthier note.

For those without dietary restrictions, the choice often comes down to preference for taste, digestion speed, and sourcing ethics. Athletes focusing on immediate post-workout recovery might prefer the rapid absorption of whey, while those seeking a slower-digesting option or following a vegan diet will benefit from the balanced profile of the plant blend.

Conclusion

Yes, both Ascent's whey and plant protein powders are complete protein sources. The brand's whey formula, derived from high-quality milk and containing native whey, naturally provides all nine essential amino acids. The plant-based formula achieves its complete status through a deliberate blend of complementary organic proteins from pea, sunflower, and pumpkin sources. Regardless of your dietary needs or preferences—whether you are an omnivore seeking dairy-based protein or a vegan searching for a plant-based option—Ascent offers a high-quality, complete protein solution to support your fitness and recovery goals. A varied diet is recommended to ensure the broadest range of nutrients, as discussed by experts at the National Institutes of Health.(https://pmc.ncbi.nih.gov/articles/PMC7760812/)

Frequently Asked Questions

A complete protein contains all nine essential amino acids (EAAs) that the human body cannot produce on its own. It matters because these amino acids are the building blocks for muscle repair, hormone synthesis, and other vital bodily functions.

Ascent's whey protein is dairy-based and therefore not suitable for vegans or those with lactose intolerance. The isolate version has less lactose than concentrate, but the plant-based option is the dairy-free choice.

Both are complete proteins and excellent for recovery. The whey protein is absorbed more quickly, while the plant protein is slower digesting and suitable for vegans. The main differences are source, absorption speed, and suitability for dietary restrictions.

Some studies have found that certain plant protein blends, like Ascent’s, can yield similar results to whey in terms of body composition and muscle thickness when following a training protocol. While whey is known for rapid absorption, the quality and completeness of Ascent's plant blend make it a highly effective vegan alternative.

Blending plant protein sources, such as pea, sunflower, and pumpkin, is necessary to achieve a complete amino acid profile. This combines the strengths of each individual protein to ensure adequate levels of all nine essential amino acids.

Ascent's whey protein contains high levels of naturally occurring leucine, a key amino acid for triggering muscle protein synthesis. This is particularly true for their native whey component, which is less processed and retains more of this amino acid.

Yes, many of Ascent's products, including their whey protein, are Informed Sport certified. This means they are third-party tested and evaluated to be free of banned substances.
