The best-evidenced ingredient in the tub. Multiple independent research groups, a double-controlled trial against an active drug comparator, and force-plate outcomes rather than owner opinion.

At this dose class, small dogs (under 11 kg) showed a 38% improvement on a validated chronic pain index. Only reachable with high-concentrate oil.

Almost always underdosed at 100 mg. The only ingredient whose canine study population explicitly included spinal disease.

Same dose you have seen elsewhere, completely different material. Plain 95% extract is the worst-absorbed form tested in beagle pharmacokinetics.

Works by oral tolerance — an immune mechanism dosed per dog, not per pound. A 12 lb dachshund gets the full dose used in trials on 66–70 lb dogs.

AAFCO requires more than 0.6 IU per gram of PUFA, and omega-3s measurably deplete α-tocopherol in dogs. It protects the marine lipids from oxidation.
