Palmitoleic acid is an omega-7 monounsaturated fatty acid. Food sources include macadamia nuts and sea buckthorn oil. Supplement forms come in capsules.
Marketers often promote this fat for skin and hair health. A handful of early studies have looked at metabolic markers, but strong human evidence is still missing for most advertised benefits.
Take the supplement with food to improve absorption. Doses vary between products because no standard amount has been set.
Long-term safety data is sparse. Anyone pregnant, nursing, or managing a medical condition should speak with a healthcare provider before use.
