The role of Ashwagandha in modulating gut parameters in dogs—a randomized double-blind placebo-controlled trial
Abstract
Introduction This study explored the role of Withania somnifera/Ashwagandha root extract (ARE) on important gut–microbiome parameters in healthy geriatric dogs. We hypothesized that ARE might promote a healthy gut by its adaptogenic and anti-inflammatory effects and improve vital parameters for healthy ageing. Methods A randomized, double-blind, placebo-controlled trial was conducted in Telangana, India. Twelve healthy geriatric Beagle dogs aged 12–15 years were enrolled. The dogs were divided into two groups to receive ARE (15 mg/kg, once daily, orally, for 2 months) or a placebo control. Various parameters were assessed, including serum haematology, biochemical markers, stool parameters, and gut–microbiome parameters. Results The erythrocyte counts and haemoglobin levels were significantly increased with ARE (p < 0.01 and p < 0.001). Moreover, a significant decrease in important serum liver biomarkers (alanine transaminase [ALT], aspartate transaminase [AST]; p < 0.01 and p < 0.001 at day 60) was observed in the ARE-treated dogs compared to that in the placebo control group. In addition, the levels of L-citrulline were significantly modulated by ARE intervention, whereas the intervention did not affect intestinal-type alkaline phosphatase (I-ALP), lactate, and carbamoyl-phosphate synthase (CPS). Interestingly, the faecal score reduced significantly with ARE (p < 0.001), while the faecal pH remained unaltered. Compared to the baseline, ARE significantly decreased two…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
