Recovery Blend Proprietary Blend
Also known as: Recovery Blend, Sports Nutrition Recovery Aid, Recovery Blend Proprietary Blend
Overview
Recovery Blend Proprietary Blend is a general term for supplement formulations designed to enhance post-exercise recovery. These blends typically combine protein sources (e.g., whey, casein), antioxidant-rich extracts (e.g., tart cherry, anthocyanins), and sometimes anti-inflammatory compounds. Their primary purpose is to accelerate recovery from exercise-induced muscle damage, improve muscle function restoration, and reduce perceived soreness. While individual ingredients like protein and tart cherry have moderate to high research maturity, evidence for proprietary blends as a whole is limited due to significant variability in their exact compositions. The quality of evidence varies, with protein supplementation having strong support, and antioxidant blends showing mixed but promising data.
Benefits
Protein supplementation is a cornerstone of recovery blends, with strong evidence supporting its efficacy. A meta-analysis of 29 studies demonstrated that post-exercise protein intake significantly improves the recovery of muscle strength (isometric and isokinetic MVC) and reduces creatine kinase (CK) levels, a marker of muscle damage, for up to 96 hours post-exercise. These benefits are supported by high-quality evidence with statistically significant effect sizes. Tart cherry supplementation has shown mixed results; some randomized controlled trials (RCTs) report attenuation of muscle soreness and improved muscle function recovery, while others, like a recent study on college-aged women, found no significant improvement in total work output. Anthocyanins, particularly from anthocyanin-rich foods, may promote functional and subjective recovery through their antioxidant and anti-inflammatory effects, though this evidence is less robust than for protein. Benefits are most pronounced in resistance-trained individuals undergoing muscle-damaging exercise, with protein effects typically observed within 24-96 hours post-exercise.
How it works
The mechanisms of action within recovery blends are multifaceted. Protein primarily supports muscle repair and synthesis by supplying essential amino acids, particularly leucine, which activates the mTOR pathways crucial for muscle protein synthesis. This process is vital for rebuilding and strengthening muscle fibers damaged during exercise. Antioxidants, such as the anthocyanins found in tart cherry, work by reducing oxidative stress and inflammation. They achieve this by scavenging free radicals and modulating inflammatory cytokines, thereby potentially mitigating secondary muscle damage and reducing post-exercise soreness. While protein is generally well absorbed, the bioavailability of anthocyanins can be moderate and influenced by the food matrix and individual gut microbiota.
Side effects
Protein supplementation is generally considered safe for healthy individuals, with minimal side effects. However, excessive intake may potentially stress the kidneys in individuals with pre-existing kidney conditions. Tart cherry and anthocyanin supplements are typically well tolerated, with rare reports of mild gastrointestinal discomfort. There are no significant drug interactions or contraindications noted for these ingredients when consumed at typical doses by healthy adults. It is important for individuals with underlying health conditions or those taking medications to consult a healthcare professional before using recovery blends, especially given the variability in proprietary formulations.
Dosage
For protein, effective doses for post-exercise recovery typically range from 20-40 grams per serving, depending on an individual's body weight, exercise intensity, and overall dietary protein intake. This should ideally be consumed within 1-2 hours post-exercise for optimal muscle protein synthesis. For tart cherry, studies often utilize 30-60 mL of tart cherry juice concentrate or an equivalent amount of powder, taken twice daily for several days both before and after intense exercise. There is no standardized dosage for anthocyanins when consumed as an isolated supplement; instead, their intake is generally recommended through a diet rich in anthocyanin-containing foods. It is crucial to adhere to product-specific dosing instructions for proprietary blends, as ingredient concentrations can vary significantly.
FAQs
Is the proprietary blend effective?
The effectiveness of a recovery blend largely depends on its specific ingredients and their dosages. The inclusion of protein is critical for muscle recovery benefits, while other components may offer supplementary effects.
Can antioxidants replace protein for recovery?
No, antioxidants cannot replace protein. While antioxidants may complement recovery by reducing oxidative stress, protein is essential for muscle repair and synthesis, a role antioxidants do not fulfill.
When is the best time to take a recovery blend?
Protein components are most effective when consumed within 1-2 hours post-exercise. Antioxidant components may require longer-term, consistent supplementation to exert their full effects.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC10393778/ – This meta-analysis of 29 studies demonstrated that protein supplementation significantly improves muscle strength recovery and reduces creatine kinase levels up to 96 hours post-exercise. It provides high-quality evidence supporting protein's role in muscle recovery.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10443385/ – This randomized controlled trial on recreationally active women found no significant improvement in total work output post-exercise with tart cherry supplementation. It highlights the inconsistent benefits of tart cherry and the need for further research.
- https://www.tandfonline.com/doi/full/10.1080/10408398.2021.1963208 – This systematic review suggests that anthocyanins may aid recovery through their antioxidant and anti-inflammatory effects. However, it notes that the evidence is less conclusive than for protein and calls for more high-quality RCTs.
