Adding Antioxidants to CBD Boosted Its Anti-Aggression and Antidepressant Effects in Stressed Mice

Low-dose CBD (2.5 mg/kg) was ineffective alone, but when combined with resveratrol (20 mg/kg) or alpha-lipoic acid (10 mg/kg), it restored attack latency, reduced aggression, and decreased immobility in the tail suspension test to levels comparable to high-dose CBD (10 mg/kg). No anxiolytic effects were observed with any combination.

Male CD1 mice (N=8 per group) were socially isolated from postnatal day 21 for 30 days to induce PTSD-like symptoms, then treated for 15 days. Behavioral tests included aggression assays, tail suspension test (depression), and hole-board test (anxiety).

If these results translate to humans, it could mean lower CBD doses might work for PTSD-related aggression and depression when paired with common supplements, potentially reducing costs and side effects associated with higher CBD doses.

This adds to growing interest in combination therapies that might enhance cannabinoid effects at lower doses. The lack of anxiety improvement is notable given that anxiety is a core PTSD symptom.

Very small sample size (8 mice per group). Mouse PTSD model has limited translation to human PTSD. Only male mice tested. Short treatment duration. Social isolation stress differs fundamentally from trauma-induced PTSD.
