In horses with osteoarthritis, a relatively low dose of either CBDa or CBG+CBD (2:1 CBG:CBD) showed pain relief after only 14 days.

The average dose was 32 mg, which should cost about $1 to $2.00 for a high-quality, full-spectrum efficacious product. I highly recommend Leotele Botanicals, a company I’ve known and trusted for over 10 years (this is an unsolicited, unpaid rec).
Role of cannabidiolic acid (CBDA) or the combination of cannabigerol/cannabidiol (CBG/CBD) in pain modulation and welfare improvement in horses with chronic osteoarthritis
“A reduction of pain scale scores and the number of WBC, monocytes and neutrophils and CD8 was observed with both CBDA and CBG/CBD treatment. No statistical differences were found in the physiological parameters. No subject required rescue analgesia or showed any adverse effects. The results of this study showed that oral administration of both CBDA and CBG/CBD oil may promote pain reduction in adult horses affected by chronic Osteoarthritis.”
