Three Gold Standard Human Clinical Trials

AprèsFlex has been the subject of seven pre-clinical and three human clinical studies. In the newest clinical study, Karlapudi and colleagues examined the efficacy of AprèsFlex in the management of joint comfort and function in a randomized, double-blind, placebo clinical trial. Sixty-seven subjects received either 100 mg/day of AprèsFlex or a matching placebo for thirty days.

Measurements included:

  • Visual Analog Score (VAS)  (Graph A)
  • The Lequesne algofunctional index (LFI)  (Graph B)
  • The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (Graph C/D/E)  
  • Serum biomarkers (MMP3, TNF, hsCRP, COMP, CPII and C2C)


Measurements were done on Days 0, 5 and 30.

The study showed that AprèsFlex:

-Provided significant reduction (p<0.05) in all the pain scores at five days compared to the placebo.
-Provided significant reduction (p<0.05) in all function scores at five days compared to placebo.

Post-trial, VAS, LFI, WOMAC pain, WOMAC stiffness, WOMAC function, and total WOMAC scores decreased in the AprèsFlex group by 45%, 40.9%, 44.4%, 66.3%, 44.4%, and 48%, respectively.

Beyond joint comfort and function improvements, AprèsFlex was also shown to offer statistically significant impact on biological markers associated with joint health and inflammation metabolism, including TNF-alpha, C-Reactive Protein (CRP), and Interleukin-6 (IL-6). It was also shown to significantly inhibit matrix metalloproteinase (MMP-3), an enzyme that breaks down cartilage, collagen, and connective tissue.

Previous studies with AprèsFlex showed 56% reduction in pain scores at 30 days. A similar study with AprèsFlex showed a 69% reduction in pain scores at 90 days.

Safety Studies

In Sprague Dawley rats, acute oral LD50 of AprèsFlex was determined to be > 5000 mg/kg. Acute dermal LD50 was > 2000 mg/kg. No changes in body weight or adverse effects were observed. In a subacute 28-day repeat dose toxicity study, the NOAEL was determined to be > 2500 mg/kg. No abnormal changes related to the study product were demonstrated in hematology, clinical chemistry, or histopathology. No adverse effects were observed.

Origin Story

A Sustainable and Socially-Responsible Ingredient

When your customers purchase a product featuring AprèsFlex, they become part of a story that is both sustainable and socially responsible. AprèsFlex is based on a proprietary Boswellia serrata gum resin extracts. Over the last 25 years, PLT has worked with our innovation partner – Laila Nutraceuticals – to create an environment that can assure not only the highest quality ingredient with proven efficacy, but an ingredient that you and your customers can be proud of.

PLT Boswellia serrata materials are sourced in India from the states of Andhra Pradesh and Madhya Pradesh. The entire Boswellia serrata supply chain starts with deep, long-term relationships developed with the most trustworthy collectors and aggregators that has been decades in the making. In conjunction with the Indian forestry department, collectors are trained on sustainable gum tapping methodology to maximize yield while maintaining the safety and health of the Boswellia serrata tree populations. Tapping locations on the tree bark as well as the frequency of tapping are carefully controlled to maintain good tree health.
