Efficacy Testing

Claim substantiation must be based on clinical studies, which are performed with effective/biologically active ingredients. Not all ingredients in dietary supplements are created equally. Therefore, the same ingredients from different producers may have different efficacy resulting in ineffective dietary supplements.

DSTest laboratories are using scientifically proven cell-based assays and animal experiments confirming effectiveness of natural ingredients. We will help you in the identification of highly efficient ingredients leading to the production of effective supplements with verified claim substantiation. ​

Bio-assays in vitro and in vivo

• Anti-oxidant stress activity
• Anti-inflammatory/ Immuno-modulatory activity
• DNA genotyping of Cannabis (hemp or marijuana)
• Probiotic effectiveness
• Anti-obesity/Anti-diabetic activity
• Anti-cancer activity
• Target-based/custom-made activity assays
• ​Inhibition of inflammation (sepsis) in mice
• Inhibition of growth of human cancer in mice

We are also developing specific/custom-made bio-assays for the testing of efficacy of ingredients and dietary supplements as required by our customers.  ​

We are testing the efficacy of ingredients and dietary supplements on the US market. 

Our tests showing anti-inflammatory/pain relieving/analgesic efficacy of CBD nanoparticles, were confirmed by testimonials of satisfied customers.  We evaluated several turmeric/curcumin dietary supplements for a “Healthy Inflammation Response” claim by the determination of their potency to inhibit inflammation in cells. Some of the supplements have strong anti-inflammatory activity, whereas others have minimal effect on inflammation. We also evaluated these turmeric/curcumin supplements for an “Antioxidant Health” claim by the determination of their antioxidative activity. Our test results show a high variability of the anti-oxidative activity in the turmeric/curcumin supplements. Some of the supplements with and without anti-inflammatory and antioxidative activity are in reality produced by the same company. The complete results of the laboratory testing of 41 different turmeric/curcumin products are here.     

Anti-obesity testing.

DSTest Laboratories are testing the potency of dietary supplements, which are marketed as anti-obesity products, for the “Inhibiting fat deposition” claim. We are testing the potency of these supplements for their potency to inhibit lipid accumulation in the fat cells. The complete results of the laboratory testing are here.

Anti-cancer testing.

​Reishi mushroom (Ganoderma lucidum) is marketed for “Healthy Aging and Longevity”. Among several effects of the Reishi mushroom is the strong effect against growth of human tumors in laboratory animals. DSTest Laboratories are testing the potency of different Reishi mushroom dietary supplements for their potency to inhibit growth of human cancer cells. The complete results of the laboratory testing are presented here.
