I currently use krill oil, probiotics and enzymes couple times a week. Mostly mixing it in with their kibble or canned food. I don’t supplement raw food usually although hiding a capsule in a ball of raw meat works very well. I’m currently using the Mercola brand but there are several others. Nordic or Grizzly for fish oils. Nzymes brand. OnlyNaturalPet.com has a selection. Sometimes I just give them a raw whole sardine instead of fish oil and then sometimes I just feed them raw tripe which has enzymes and beneficial organisms. Another brand I use is Garden of Life.
