Omega-3 fatty acids provide anti-inflammatory benefits, support a healthy coat, and contribute to immune function. While rabbits do not need fish oil or marine sources, they obtain small amounts of alpha-linolenic acid (ALA, a plant-based omega-3) from leafy greens and hay. The amounts are modest but sufficient for a healthy herbivore on a well-balanced diet.
A serving of fresh kale or watercress (about 30g) provides a small but meaningful amount of ALA omega-3 — rabbits do not have a well-defined omega-3 requirement, but the natural amounts found in leafy greens and grass hay are considered adequate. There is no need for supplementation in healthy rabbits.
0.35% of daily nutrient intake
Omega-3 Fatty Acids makes up 0.35% of your domestic rabbit's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
Deficiency is very unlikely on a normal rabbit diet. Theoretical signs would include dry skin, a dull coat, and increased inflammatory responses.
Excess omega-3 from plant foods is not a concern. Rabbits should never be given fish oil or marine omega-3 supplements, which are inappropriate for their herbivorous digestive system.

The balance between omega-6 and omega-3 fatty acids influences inflammatory responses throughout the body. Omega-6 tends to promote inflammation while omega-3 has anti-inflammatory effects. In rabbits, a natural hay-and-greens diet provides a reasonably balanced ratio, but feeding excessive seeds or nuts skews the balance heavily toward omega-6, potentially promoting chronic low-grade inflammation.
What this means: Keep seeds and nuts to an absolute minimum — no more than a few per week as rare treats. The natural omega-6 to omega-3 ratio in timothy hay and leafy greens is well-balanced and appropriate for your rabbit's needs without supplementation.
