Overview
The term 'proprietary blend' refers to a mixture of ingredients used in dietary supplements where the exact amounts of individual components are not disclosed on the label, often protected as trade secrets. This lack of transparency poses significant challenges for consumers and healthcare providers, as the active ingredients may be absent, present in subtherapeutic doses, or highly variable between manufacturers [1][3]. Proprietary blends are commonly found in herbal and combination supplements, which may offer synergistic benefits, such as in traditional Chinese medicine formulations or combination therapies for complex diseases like diabetes [2][9]. However, the absence of standardization and regulatory oversight increases the risk of impurities, adulterants, and potential herb-drug interactions, especially when used without medical supervision [10][8]. While some proprietary herbal formulations show promise in areas like cancer therapy or dermatology, their efficacy and safety are difficult to evaluate due to limited pharmacokinetic and pharmacodynamic data [6][7].

Research
Dietary supplements, including proprietary blends, lack FDA approval and standardization, leading to variability and potential impurities.
Traditional Chinese medicine uses multi-herb formulations to enhance efficacy and reduce toxicity, supporting the concept of synergistic blends.
Dietary supplements are often used without medical input, and data on their pharmacology are limited and of poor quality.
Combination therapy with phytochemicals may improve diabetes management, but bioavailability and formulation challenges exist.
Herbal medicine use is increasing globally, but interactions with conventional drugs can lead to adverse events.
Herbal supplements are regulated differently from drugs, requiring a holistic approach to their use.
Herbal medicinal products, including standardized extracts and mixtures, are used as dietary supplements in cancer care.
In the U.S., herbal products are unregulated as drugs, leading to lack of standardization in concentration and purity.
Combination of synthetic drugs with phytochemicals may reduce side effects but requires optimized formulations.
Lack of oversight in herbal supplement use increases risk of herb-drug interactions and improper dosing.
