Tamaflex
Also known as: TamaFlex, NXT15906F6, Tamarindus indica seed extract and Curcuma longa rhizome extract blend
Overview
TamaFlex is a proprietary botanical dietary supplement formulated from extracts of *Tamarindus indica* (tamarind) seeds and *Curcuma longa* (turmeric) rhizome. It is primarily used to alleviate joint pain and improve musculoskeletal function, particularly in individuals with osteoarthritis. The formulation contains a minimum of 65% proanthocyanidins (from tamarind) and 3% total curcuminoids (from turmeric), both known for their anti-inflammatory and antioxidant properties. TamaFlex is available in capsule or tablet form and is typically taken once daily. Research suggests that TamaFlex may reduce inflammation and improve joint health, but further comprehensive studies are needed to confirm these effects and establish long-term safety. The available evidence consists mainly of small-scale randomized controlled trials (RCTs) with some methodological limitations, indicating an emerging but not fully established level of research maturity.
Benefits
TamaFlex has demonstrated potential benefits in reducing knee joint pain and improving musculoskeletal function in individuals with mild to moderate osteoarthritis. Studies have shown significant improvements in WOMAC scores, indicating reduced pain and enhanced joint function within 30 days of supplementation. Additionally, TamaFlex may reduce inflammation, as indicated by decreased levels of high-sensitivity C-reactive protein (hs-CRP). These benefits are primarily observed in adults with osteoarthritis. While specific effect sizes are not widely reported, the clinical significance is noted in improved joint function and pain reduction. The quality of evidence is considered moderate, based on small-scale RCTs.
How it works
TamaFlex's mechanism of action primarily involves anti-inflammatory pathways. The curcuminoids in turmeric may target NF-κB and other inflammatory pathways, while proanthocyanidins from tamarind may exert antioxidant effects. This combination potentially reduces pro-inflammatory cytokines and modulates inflammatory biomarkers like hs-CRP, affecting both the musculoskeletal and immune systems. The synergistic effect of these compounds contributes to reduced inflammation and improved joint health. Specific data on the absorption and bioavailability of TamaFlex components is limited, but the lipophilic nature of curcumin suggests that its absorption may be enhanced with fatty meals.
Side effects
TamaFlex is generally considered safe based on available studies, but comprehensive safety data is limited. Common side effects are not well-documented, but potential gastrointestinal upset, similar to other botanical supplements, may occur. Rare side effects have not been reported. Due to curcumin's anti-coagulant properties, potential interactions with blood thinners exist, necessitating caution for individuals on such medications. While no specific contraindications are noted, caution is advised during pregnancy and breastfeeding due to a lack of safety data. Elderly individuals may require monitoring due to potential interactions with other medications. It is important to consult with a healthcare provider before use, especially for those with pre-existing conditions or taking other medications.
Dosage
The minimum effective dose of TamaFlex, as used in clinical trials, is 250 mg per day. Optimal dosage ranges have not been established beyond this studied dose. The maximum safe dose is also undefined. TamaFlex is typically taken once daily after breakfast. It is commonly available in capsule or tablet form. Due to the lipophilic nature of curcumin, bioavailability may be enhanced when taken with fatty meals. There are no specified required cofactors. It is crucial not to exceed the recommended dosage without consulting a healthcare professional.
