Walk into any pet store and you'll find a wall of supplements promising better coats, joints, and digestion. The truth for fresh feeders is more modest: a properly balanced raw diet covers most bases, and only a few supplements earn their place.
Start with a balanced base
The best “supplement” is correct ratios. Muscle meat, bone, and secreting organs—rotated across proteins—deliver the bulk of what your dog needs. If the foundation is right, you're supplementing gaps, not building the diet out of pills.
Omega-3s are the most common real gap
Most raw diets are heavier in omega-6 than omega-3. Adding an omega-3 source—small oily fish like sardines a couple of times a week, or a quality fish oil—supports skin, coat, and joint health. This is the one addition many balanced feeders genuinely benefit from.
Other situational additions
Vitamin E is sometimes added when feeding a lot of fish oil, since omega-3s increase the body's need for it. Kelp can provide iodine if you're not feeding thyroid tissue. Joint support like green-lipped mussel may help older dogs. Each of these answers a specific need—not a general “more is better” impulse.
What you usually don't need
If your ratios are right and you rotate proteins, you generally don't need a multivitamin, calcium powder (bone handles that), or the majority of the shelf. More is not safer—fat-soluble vitamins in particular can accumulate.

Educational only—not veterinary advice. Talk to your vet before adding supplements, especially for dogs with health conditions.
