Overview
NOW's omega-3 fish oil supplement for cats and dogs, sold as 180 unflavored softgels, with joint health listed as the product benefit.
- 180 softgels per bottle
- Fish oil omega-3 formula
- Joint health benefit listed
- For cats and dogs
Who it's for
Dog or cat owners looking to add omega-3 support for joints, particularly for a large-breed dog per the listed breed sizing, when the pet's regular food doesn't already include added fish oil.
Strengths and trade-offs
Drawn from this product's published specifications.
- Covers both cats and dogs
- Softgel dosing avoids liquid mess
- 180-count supply for ongoing use
- Fish-based, not suitable for fish-allergic pets
- Unflavored, so palatability with picky pets is untested here
Performance notes
Each softgel delivers a fixed dose of fish-derived omega-3, targeted at joint health, and the 180-count bottle is sized for ongoing daily use rather than a short course.
