Is myprotein a complete protein? A Guide to Myprotein's Amino Acid Profiles

4 min read

Derived from milk, whey protein is a classic complete protein, providing all nine essential amino acids the body needs. The question, 'Is myprotein a complete protein?', has a nuanced answer, as it depends on the specific product you choose from their diverse range of supplements.

Quick Summary

Myprotein offers different protein products; some are complete proteins like whey and casein, while vegan options achieve a complete amino acid profile through blended ingredients. Understanding the source is key.

Key Points

  • Not All Products Are Identical: The answer to 'Is myprotein a complete protein?' depends on the specific product, with animal and plant-based versions having different sources.

  • Whey and Casein are Complete: Myprotein's whey and casein products, both derived from milk, are naturally complete proteins containing all nine essential amino acids.

  • Vegan Blends are Complete: Vegan protein products from Myprotein are formulated by blending different plant proteins, such as pea and fava bean, to provide a complete amino acid profile.

  • Digestion Speed Varies: Whey is fast-absorbing for immediate post-workout needs, while casein is slow-digesting for sustained release over several hours.

  • Check the Label: To be certain, always check the product's ingredient list and nutritional information to understand its protein source and whether it is a complete protein.

Understanding the 'Complete Protein' Concept

Before diving into specific Myprotein products, it is crucial to understand what defines a complete protein. A protein is considered "complete" when it contains all nine of the essential amino acids (EAAs). The human body cannot produce these amino acids, so they must be obtained through diet. 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 almost always complete. Plant-based proteins are often incomplete, meaning they may lack one or more EAAs. However, many vegan protein powders, including those from Myprotein, are intelligently blended to ensure a full spectrum of amino acids.

Myprotein's Animal-Based Complete Proteins

Impact Whey Protein

Myprotein's bestselling Impact Whey Protein is derived from milk and is widely recognized as a complete protein source. It provides a full amino acid profile, including high levels of the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine, which are critical for muscle protein synthesis and recovery. Its fast absorption rate makes it an ideal choice for post-workout shakes when your muscles need amino acids quickly. The product's consistent popularity over the years is a testament to its effectiveness and complete nutritional offering.

Impact Micellar Casein

Another animal-based product, Micellar Casein, is also a complete protein containing all nine essential amino acids. However, unlike whey, casein is a slow-digesting protein. Its absorption rate is prolonged, providing a steady drip-feed of amino acids to the muscles over several hours, making it ideal for consumption before bed or between meals to prevent muscle breakdown. This slow release is a key differentiator from the faster-acting whey protein, offering a strategic benefit for sustained muscle support.

Myprotein's Vegan and Plant-Based Protein Offerings

Myprotein caters to plant-based diets with its Myvegan line, offering products like the Vegan Protein Blend. As single-source plant proteins often lack a complete amino acid profile, Myprotein's vegan products are formulated by blending different protein sources.

Myvegan Protein Blend

Myprotein's Vegan Protein Blend typically uses a mix of pea and fava bean isolates to create a complete protein source. This combination ensures that the final product contains all nine essential amino acids, mirroring the completeness of animal-derived proteins. It is an effective solution for vegans and vegetarians looking to support muscle growth and maintenance without relying on dairy or other animal products. Myprotein specifically markets this blend as a complete protein source containing all nine essential amino acids.

Comparison of Myprotein Protein Types

To help you decide which Myprotein product is right for you, here is a comparison of their key protein types based on several factors.

Feature Impact Whey Protein Impact Micellar Casein Myvegan Protein Blend
Protein Source Milk (Whey) Milk (Casein) Pea & Fava Bean
Protein Completeness Complete Complete Complete (via blend)
Digestion Speed Fast-absorbing Slow-absorbing Moderate
Ideal Timing Post-workout Before bed or between meals Any time of day
Key Benefit Rapid muscle recovery Sustained amino acid release Plant-based complete protein
Dietary Notes Not for vegans or dairy-sensitive Not for vegans or milk allergy sufferers Vegan, dairy-free

Making the Right Choice

Choosing the right protein from Myprotein depends on your dietary restrictions and fitness goals. If you do not have dietary restrictions, both whey and casein offer excellent, complete protein options. Your choice between them will depend on your desired absorption speed—whey for immediate recovery and casein for sustained release. However, if you follow a vegan or plant-based diet, selecting the Myvegan Protein Blend is essential to ensure you receive a complete amino acid profile without relying on animal products. The careful formulation of the vegan blend guarantees that it rivals the completeness of its animal-based counterparts, providing a reliable source of all nine EAAs.

It is important to remember that protein supplements are intended to complement a varied and balanced diet, not replace it. Whole food sources of protein should always be prioritized, and supplements can be used to conveniently and efficiently meet your daily protein targets. For example, a post-workout shake made with Impact Whey is a convenient way to kickstart recovery, but it shouldn't overshadow the importance of a protein-rich meal later in the day. Many resources, including official guidance from health bodies like the NCBI, can provide more detailed information on essential amino acids for those interested in deepening their nutritional knowledge.

Conclusion

The short answer to the question "Is myprotein a complete protein?" is yes, for many of their products, but with important distinctions. Myprotein's whey and casein products are inherently complete due to their dairy origin. For those following a vegan diet, the Myvegan Protein Blend is specifically formulated using complementary pea and fava bean proteins to provide a complete amino acid profile. Ultimately, regardless of your dietary path, Myprotein offers reliable, complete protein options that can help you achieve your fitness and nutritional goals. By understanding the source and formulation of each product, you can make an informed decision that best suits your needs.

Frequently Asked Questions

A complete protein is a food source that contains all nine of the essential amino acids (EAAs) that the human body cannot produce on its own and must obtain from diet.

Yes, Impact Whey Protein is a complete protein derived from milk, containing all nine essential amino acids and a high concentration of BCAAs.

Yes, Myprotein's Vegan Protein Blend is a complete protein. It achieves a full amino acid profile by combining multiple plant-based protein isolates, like pea and fava bean.

Neither is inherently 'better'; they serve different purposes. Whey is best post-workout for rapid absorption, while casein is slow-digesting and ideal for sustained amino acid release, like before bed.

Yes, for optimal muscle protein synthesis and recovery, it is important to consume complete proteins or complementary incomplete proteins throughout the day to ensure your body has access to all nine essential amino acids.

You can determine if a protein powder is complete by checking the nutrition label. Look for products derived from animal sources like whey or casein, or for plant-based powders that specify they are a complete blend.

Many of Myprotein's products, including some bars, are formulated to be complete proteins. Always check the nutritional information on the packaging, which lists the ingredients and amino acid content to confirm.
