In this study, ashwagandha root extract supplementation significantly improved processing speed (p=0.040), delayed word recall (p=0.038, d=0.59), Stroop accuracy (p=0.021, d=0.61), Corsi span (p=0.013, d=0.66), and choice reaction time accuracy (p=0.005, d=0.75), alongside better parent-reported sleep (SDSC, p=0.035), with no significant adverse events.

In this study, crocin significantly improved Follicle-stimulating hormone levels (P = 0.048) and reduced hirsutism, as measured by the Ferriman–Gallwey score (P = 0.042), by day 90. It also significantly improved acne severity (P = 0.03), with no patients in the crocin group having severe acne at the end of the study. However, crocin did not significantly improve fasting blood sugar.

Written by Tabish Mehraj, PhD. In this study, a significant increase in bioavailability with micellar formulation was observed, with 18.9-fold higher Cmax (95% CI: 1.9–30.7 ng/mL vs. 74.4–288.3 ng/mL; p = 0.007) vs. 178–612.5 ng·h/mL; p = 0.015). Tmax was 0.5 (95% CI:0.5–4.0) hours for the micellar formulation versus 2.5 (95% CI: 0.5–8.0) hours. No adverse events were observed in either group. Compared to the standard, the micellar formulation showed superior pharmacokinetic outcomes.

Headache severity differed significantly among groups (p < 0.001), and comfort was significantly higher with both acetaminophen and lavender than with control (p < 0.001).

Written by Tabish Mehraj, PhD. In this study, 117 participants were assessed, and both inulin supplementation and physiotherapy-supported exercise significantly reduced knee pain, with no synergistic effect. Inulin also improved pain sensitivity and grip strength and increased butyrate and GLP-1 levels, while physiotherapy improved mobility and lower-body function.
In this interview, Sarah Burden, Senior Director of Sales at People Science, discusses the importance of making clinical research more accessible, affordable, and representative. She explains how removing traditional barriers to participation can help natural product companies generate real-world evidence and give consumers greater confidence in the products they choose.
Written by Tabish Mehraj, PhD. In this randomized, placebo-controlled study, the peppermint group had a significant reduction in systolic blood pressure after 20 days compared with the placebo group. Blood pressure was about 8.5 mmHg lower in the peppermint group (95% CI: −14.24 to −2.73; effect size d = −0.94).
