"Proprietary Blend (Herb/Botanical)" is a broad term that refers to a mixture of various herbal and botanical ingredients whose specific contents and amounts are not always disclosed. The use of herbal blends in bodybuilding is justified primarily by traditional practices and anecdotal reports rather than robust scientific validation. Traditional medicine systems—such as Ayurveda, Traditional Chinese Medicine, and Western herbalism—have long used herbs like ashwagandha, tribulus terrestris, fenugreek, and ginseng for their purported benefits on strength, stamina, and recovery. These herbs are often included in proprietary blends for their adaptogenic, energy-boosting, or hormone-modulating effects, which are believed to support muscle growth and exercise performance.

However, scientific evidence supporting the efficacy of most herbal blends for bodybuilding is limited and often of low quality. While some individual herbs have shown modest effects in small studies (e.g., ashwagandha for strength and recovery, fenugreek for testosterone support), the results are inconsistent, and there is little high-quality research on the effects of multi-ingredient proprietary blends as a whole. Furthermore, the lack of transparency in ingredient doses complicates the assessment of both efficacy and safety. Overall, while the use of proprietary herbal blends in bodybuilding has roots in traditional practice, their benefits remain insufficiently verified by rigorous scientific research.
