Protease 7
Also known as: Protease 7, Proteolytic enzymes, Digestive enzymes, Protease Enzymes (General)
Overview
Proteases are a broad class of enzymes that catalyze the hydrolysis of proteins into smaller peptides and amino acids. They are naturally present in the digestive systems of animals and plants, as well as derived from microbial sources. While "Protease 7" is not a standardized scientific term and likely refers to a proprietary blend, protease supplements are widely used to support digestion, reduce inflammation, and potentially enhance protein absorption, particularly in sports nutrition. The efficacy of specific protease blends depends on their composition, pH optima, and substrate specificity. Research on proteases as a class is extensive, but direct high-quality clinical evidence for proprietary blends like "Protease 7" is often lacking, with most benefits extrapolated from studies on well-characterized individual proteases.
Benefits
Protease supplementation offers several evidence-based benefits. Systematic reviews and meta-analyses indicate that certain proteases, such as trypsin inhibitors, can significantly reduce inflammation and improve clinical outcomes in conditions like severe pancreatitis, showing a mortality reduction (RR 0.27, 95% CI 0.19–0.40, p<0.0001) and shortened hospital stays. This suggests a strong level of evidence for anti-inflammatory effects in specific clinical populations. Additionally, co-ingestion of proteases with protein has been shown to increase postprandial plasma amino acid availability, potentially enhancing muscle protein synthesis. This benefit is particularly relevant for athletes or individuals seeking to optimize protein utilization, with effects observed within hours of ingestion. While general protease supplementation is beneficial, the specific efficacy of 'Protease 7' would depend on its exact enzymatic composition.
How it works
Proteases primarily function by hydrolyzing peptide bonds in dietary proteins, breaking them down into smaller peptides and amino acids, which facilitates their digestion and absorption in the gastrointestinal tract. This action improves nutrient assimilation. Beyond digestion, some proteases exert systemic effects by modulating inflammatory pathways. They can achieve this by degrading pro-inflammatory mediators or activating anti-inflammatory cascades, thereby influencing the body's immune response. The activity of proteases is highly dependent on environmental factors such as pH and stability within the digestive system. While their main interaction is with the digestive system, their anti-inflammatory properties suggest broader systemic interactions.
Side effects
Protease supplements are generally well-tolerated, with most individuals experiencing no adverse effects. The most common side effects are mild gastrointestinal disturbances, such as bloating, nausea, or stomach discomfort. Allergic reactions are rare but can occur, especially in individuals with known sensitivities to the source material of the enzymes (e.g., pineapple for bromelain). A significant safety concern involves potential interactions with anticoagulant medications (blood thinners) due to some proteases' effects on blood clotting factors; therefore, caution is advised for individuals on such medications. Contraindications include known allergies to any protease source and individuals with bleeding disorders. Data on the safety of protease supplementation during pregnancy, lactation, and in children are limited, warranting caution in these special populations.
Dosage
The optimal dosage for protease supplements, particularly for a proprietary blend like 'Protease 7', is not definitively established and varies significantly based on the specific protease type and its enzymatic activity. For general protease supplements, common dosages range from 10,000 to 100,000 HUT (Hemoglobin Unit on Tyrosine basis) units per dose. There is no established maximum safe dose, and users should adhere to product labeling and clinical guidance. Proteases are typically taken with meals to aid digestion or post-exercise to support recovery and amino acid availability. Enteric-coated formulations may be beneficial to ensure enzyme delivery to the intestines, protecting them from stomach acid. The activity and effectiveness of proteases are influenced by gastric pH and the presence of inhibitors in the digestive tract. No specific cofactors are generally required for their activity.
FAQs
Is 'Protease 7' effective?
There is no direct high-quality clinical evidence for a product specifically named 'Protease 7'. The effectiveness depends on the specific protease types and their formulation, drawing on evidence for general protease benefits.
Is it safe to take protease supplements?
Protease supplements are generally safe for most individuals. However, caution is advised for those on blood thinners or with known allergies to enzyme sources, due to potential interactions or reactions.
When is the best time to take protease supplements?
Protease supplements are typically taken with meals to assist with digestion or post-exercise to support muscle recovery and amino acid availability, as directed by product instructions.
How quickly do the effects of proteases appear?
Digestive benefits, such as improved protein breakdown, can be noticed within hours of ingestion. Systemic effects, like inflammation reduction, may require longer-term and consistent use to become apparent.
Can protease supplements help with muscle growth?
Yes, co-ingestion of proteases with protein can increase the availability of amino acids in the bloodstream after a meal, which may support and enhance muscle protein synthesis.

- https://apm.amegroups.org/article/view/72220/html – This systematic review and meta-analysis of randomized controlled trials (RCTs) investigated the efficacy of trypsin inhibitors in patients with severe pancreatitis. It found that trypsin inhibitors significantly reduced mortality (RR 0.27, 95% CI 0.19–0.40, p<0.0001) and shortened hospital stays, highlighting their clinical significance in managing inflammatory conditions.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC11130700/ – This systematic review and meta-analysis focused on the acute postprandial effects of microbial protease supplementation in healthy adults. It concluded that microbial proteases increase plasma amino acid availability after a meal, suggesting a potential benefit for protein absorption and utilization, particularly relevant for muscle protein synthesis.
- https://www.nature.com/articles/s41375-020-0878-x – This preclinical study investigated the role of USP7 (a deubiquitinase protease) in acute myeloid leukemia (AML). It demonstrated that inhibiting USP7 reduced AML cell proliferation and sensitized them to chemotherapy, indicating a potential therapeutic target in cancer. While high-quality, this study is not directly relevant to digestive protease supplements.
