A Proprietary Blend From Aqueous Extracts Of
Also known as: A Proprietary Blend From Aqueous Extracts Of, Botanical Aqueous Extracts, Herbal Aqueous Extracts, Standardized Botanical Blends, Proprietary Botanical Aqueous Extracts
Overview
Proprietary blends from aqueous extracts refer to formulations combining multiple botanical extracts obtained using water-based extraction methods. These blends are often standardized for specific bioactive compounds, such as punicalagins from *Punica granatum*, curcuminoids from *Curcuma longa*, or boswellic acids from *Boswellia serrata*. They are primarily utilized for their anti-inflammatory, antioxidant, and hormonal balancing properties, often targeting symptoms associated with aging or inflammatory conditions. The key characteristic of these blends is the use of standardized extraction processes to ensure consistent phytochemical profiles, aiming for synergistic effects from combining different plant materials. Research, including randomized controlled trials (RCTs) and meta-analyses, supports their efficacy and safety in specific contexts, such as improving aging male symptoms and reducing inflammation. The quality of evidence varies by specific blend but includes well-conducted studies with adequate sample sizes and placebo controls.
Benefits
Proprietary botanical aqueous extracts offer several evidence-based benefits, primarily due to their anti-inflammatory and antioxidant properties. For instance, LN18178, a blend of *Punica granatum* fruit rind and *Theobroma cocoa* seed extracts, has shown efficacy in reducing aging male symptoms and improving serum testosterone levels in healthy men aged 36-55 years, as demonstrated in a 56-day randomized controlled trial. Another blend, NXT15906F6, comprising *Tamarindus indica* seeds and *Curcuma longa* rhizome, has demonstrated significant anti-inflammatory effects, supported by a meta-analysis of preclinical and clinical studies. Similarly, CLBS, a blend of *Curcuma longa* and *Boswellia serrata*, is standardized for curcuminoids and boswellic acids, which are well-known for their anti-inflammatory and joint health benefits. Clinical studies report statistically significant improvements (p < 0.05) in symptom scores and biochemical markers, with benefits typically manifesting over several weeks to months of consistent supplementation. The strength of evidence for these specific blends is considered high due to the inclusion of well-designed RCTs and meta-analyses.
How it works
These proprietary blends exert their effects primarily through antioxidant, anti-inflammatory, and hormonal modulation pathways. For example, curcuminoids, found in *Curcuma longa* extracts, are known to inhibit the NF-κB signaling pathway, thereby reducing the production of inflammatory mediators. Punicalagins from *Punica granatum* provide potent antioxidant effects by scavenging free radicals and reducing oxidative stress. Boswellic acids, derived from *Boswellia serrata*, inhibit 5-lipoxygenase, an enzyme involved in the synthesis of pro-inflammatory leukotrienes. The aqueous extraction method is crucial as it selectively preserves water-soluble phytochemicals, which can enhance the bioavailability of certain compounds. These compounds interact with various molecular targets, including inflammatory cytokines, oxidative stress mediators, and hormone receptors, to produce their therapeutic effects.
Side effects
Overall, proprietary blends from aqueous extracts have demonstrated good safety profiles in clinical trials, with no serious adverse events reported. Common side effects are rare, mild, and typically involve transient gastrointestinal discomfort, such as mild stomach upset. No significant drug interactions or contraindications have been reported in the reviewed studies. These blends have been well-tolerated by specific populations, such as elderly males, under study conditions. However, as with any botanical supplement, individuals with pre-existing medical conditions, those taking prescription medications, or pregnant/nursing women should consult a healthcare professional before use. While generally safe, individual sensitivities to specific plant components within the blend are possible, and users should discontinue use if adverse reactions occur.
Dosage
Dosage recommendations for proprietary botanical aqueous extracts vary significantly depending on the specific blend and its standardized active compounds. For instance, the LN18178 blend (*Punica granatum* and *Theobroma cocoa* extracts) was administered at doses standardized to contain ≥3.5% punicalagins and 0.5% theobromine over a 56-day period in clinical trials. Another example, NXT15906F6 (*Tamarindus indica* and *Curcuma longa*), was standardized to contain ≥65% proanthocyanidins and 3% curcuminoids, administered in specific ratios (e.g., 6:3:1 for Tamarindus:Curcuma:excipients). Optimal dosing requires strict adherence to the concentrations of standardized extracts used in clinical trials. The timing of administration is generally daily, taken orally. It is crucial to follow the manufacturer's specific instructions for each proprietary blend, as the precise composition and concentration of active ingredients will dictate the effective and safe dosage. There are no universally established upper limits for these blends, but adherence to clinically tested dosages is recommended to ensure safety and efficacy.
FAQs
Are proprietary blends from aqueous extracts safe?
Yes, clinical trials generally report good tolerability and safety for these blends, with rare and mild side effects like gastrointestinal discomfort. No serious adverse events have been commonly reported.
How soon can benefits be expected from these blends?
The onset of benefits typically varies depending on the specific blend and the condition being addressed, but improvements are generally observed within 4 to 8 weeks of consistent supplementation.
Do proprietary blends work better than single extracts?
Synergistic effects are hypothesized when combining multiple extracts in a blend, potentially leading to enhanced efficacy compared to single extracts. However, more direct comparative studies are needed to definitively confirm this.
Research Sources
- https://pmc.ncbi.nlm.nih.gov/articles/PMC9346391/ – This randomized, double-blind, placebo-controlled trial investigated the efficacy of LN18178 (a blend of Punica granatum and Theobroma cocoa extracts) in 56 healthy aging males over 56 days. The study found significant improvements in aging male symptoms and serum testosterone levels (p < 0.05), supporting the blend's potential for hormonal balance and symptom relief in this population. The study design was robust, contributing to high-quality evidence.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10284097/ – This meta-analysis focused on NXT15906F6, a blend of Tamarindus indica and Curcuma longa extracts, combining preclinical and clinical data. It demonstrated the anti-inflammatory efficacy of standardized extracts containing ≥65% proanthocyanidins and 3% curcuminoids. The analysis included RCTs with adequate sample sizes (n≥30 per group) and showed statistically significant symptom improvement (p < 0.05), highlighting its potential for inflammatory conditions.
