Palmitoleic acid is an omega-7 monounsaturated fatty acid often described as a lipokine because it signals between tissues. It’s concentrated in macadamia oil and sea-buckthorn oil and is studied for effects on metabolic health and inflammatory tone. Through these signaling roles, palmitoleic acid can indirectly affect joint comfort and brain function by influencing systemic inflammation and metabolic balance.

10. Stearidonic Acid (SDA)

Stearidonic acid is a plant-based fatty acid that acts as a downstream product of alpha-linolenic acid conversion. It’s found in echium oil, hemp, and certain seed oils, and it can be more readily converted into longer-chain anti-inflammatory omega-3 metabolites compared with some other plant omega-3 precursors. For individuals who favor plant-based choices, SDA-containing oils offer an alternative pathway to generate bioactive lipids that support inflammation resolution.
