The Effect of Astaxanthin After Varicocele Surgery on Antioxidant Status and Semen Quality in Infertile Men: A Triple-Blind Randomized Clinical Trial

Written by Keely Puchalski, ND. Results from this small triple-blind RCT suggest 90 days of astaxanthin (6 mg/day) after varicocelectomy improved sperm motility, increased seminal antioxidant capacity, upregulated NRF2-pathway gene expression, and reduced pro-inflammatory cytokines in infertile men with varicocele, though the study is limited by small sample size, retrospective trial registration, and lack of baseline data and protein-level validation.

A Comparative Study of Aloe Vera and Thyme Honey Oral Rinse for the Management of Xerostomia in Type 2 Diabetes: Evidence from a Randomized Controlled Trial

Written by Tabish Mehraj, PhD Science Writer. This study evaluated the effectiveness of honey and aloe vera in management of xerostomia over a 4-week period (p=0.002). Both interventions significantly reduced xerostomia symptoms, increased salivary flow rate and improved quality of life as compared to saline (p<0.001), moreover salivary nitric oxide levels were highest in thyme group followed by aloe vera, resulting in enhanced function of the salivary gland.

Grape Seed Extract Improves Cardiovascular and Hepatic Parameters in Non-Alcoholic Fatty Liver Disease: A Randomized, Double-Blind, Placebo-Controlled Trial

Written by Tabish Mehraj, PhD, Science Writer. Grape seed extract (GSE) supplementation over two months showed great effectiveness as compared to placebo, the GSE group showed significant improvements in lipid profile (p < 0.05), blood pressure parameters (p < 0.001), insulin resistance markers (p < 0.05), and insulin sensitivity (p < 0.05). Additionally, liver enzyme levels and hepatic steatosis severity were significantly reduced (p < 0.05; p = 0.002). Overall, GSE supplementation showed beneficial metabolic and hepatic effects.
