What is a Complete Protein?
Before analyzing specific Paleovalley products, it's essential to understand the definition of a complete protein. Proteins are made up of building blocks called amino acids. Of the 20 amino acids, nine are considered 'essential' because the human body cannot produce them and must obtain them from food. A protein source is considered 'complete' when it contains adequate levels of all nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Typically, animal-based proteins like meat, dairy, and eggs are complete proteins, while many plant-based sources are incomplete unless combined effectively.
Paleovalley 100% Grass Fed Whey Protein
Paleovalley's 100% Grass Fed Whey Protein with Colostrum is a complete protein. According to the company's own product information and supported by general knowledge of whey protein, this product contains all nine essential amino acids. Whey is a milk-derived protein known for its high biological value and is rich in branched-chain amino acids (BCAAs), which are particularly important for muscle building and repair.
- Made from 100% grass-fed cow's milk
- Contains all 9 essential amino acids
- Rich in muscle-building BCAAs
- Minimally processed to preserve nutrients
Paleovalley 100% Grass Fed Bone Broth Protein
In contrast to the whey, Paleovalley's Bone Broth Protein is not a complete protein. This is because bone broth protein is primarily made of collagen, which lacks the essential amino acid tryptophan. While rich in other beneficial amino acids like glycine, proline, and glutamic acid, it cannot be considered a standalone complete protein source. Paleovalley's customer support and other nutritional experts confirm this distinction.
- Made from 100% grass-fed beef bones
- High in collagen, excellent for joints, skin, and gut health
- Not a complete protein source
- Should be combined with other protein sources for a complete amino acid profile
Paleovalley 100% Grass Fed Beef Sticks
The 100% Grass Fed Beef Sticks from Paleovalley are sourced from 100% grass-fed and finished beef. Since beef is a prime example of a complete protein, the protein within these sticks is complete, containing all nine essential amino acids. While a single stick provides a modest amount of protein (typically 6 grams per serving), it comes from a complete source. The fermentation process used to preserve the sticks also adds beneficial probiotics, further enhancing their nutritional value.
Protein Completeness: Product Comparison
| Feature | Paleovalley Whey Protein | Paleovalley Bone Broth Protein | Paleovalley Beef Sticks |
|---|---|---|---|
| Complete Protein? | Yes | No | Yes |
| Primary Source | 100% Grass-Fed Whey & Colostrum | 100% Grass-Fed Beef Bones (Collagen) | 100% Grass-Fed & Finished Beef |
| Essential Amino Acids | All 9 | Lacks Tryptophan | All 9 |
| Primary Benefits | Muscle building, immune support, weight management | Joint, skin, gut health | Convenient protein snack, probiotics |
| Complementary Foods Needed? | No | Yes | No |
Why Amino Acid Completeness Matters
While incomplete proteins are not inherently 'bad,' understanding the difference helps you meet your nutritional needs effectively. For those relying on protein supplements for muscle growth, choosing a complete protein like whey is more efficient. However, if your goal is to support joint health, collagen-rich bone broth is highly beneficial, even if it is an incomplete protein. A varied diet ensures you receive all essential amino acids throughout the day, a concept called complementary proteins. For example, a person using bone broth protein could consume a handful of nuts or seeds later to round out their amino acid intake. For more detailed information on protein intake guidelines and collagen's role, refer to studies like those published by the National Institutes of Health.
Conclusion: Strategic Supplementation with Paleovalley
The question of whether is Paleovalley a complete protein has a nuanced answer that depends entirely on the specific product. The 100% Grass Fed Whey Protein with Colostrum and the Grass Fed Beef Sticks are sourced from complete protein sources. In contrast, the Bone Broth Protein, while offering many health benefits for gut, skin, and joint health due to its high collagen content, is not a complete protein. A strategic approach to supplementation means choosing the right product for your specific health goals and combining incomplete protein sources where necessary to ensure your body receives all the essential amino acids it needs.
