As a nutritionist, I am often asked about the benefits of lesser-known fatty acids. One such nutrient gaining attention is plant-derived Omega-7, particularly palmitoleic acid, which is primarily sourced from sea buckthorn berry oil, macadamia nuts, and avocado. While Omega-3 and Omega-6 fatty acids are well-known, Omega-7 is emerging as a potent ally for skin, cardiovascular, and metabolic health.
What Is Plant Omega-7?
Omega-7, especially palmitoleic acid, is a monounsaturated fatty acid found in certain plants and marine sources. Sea buckthorn (Hippophae rhamnoides) stands out as the richest plant-based source, offering a unique blend of fatty acids, vitamins, and antioxidants346. Unlike Omega-3 and Omega-6, Omega-7 is not considered essential, but its health benefits are increasingly supported by scientific research.
Omega-7 for Skin Health
- Hydration and Barrier Support: Omega-7 is structurally similar to human sebum, making it highly effective at reinforcing the skin’s natural barrier. It limits water loss, keeps skin soft and supple, and protects against environmental stressors678.
- Anti-Aging and Regeneration: Clinical studies have shown that Omega-7 supplementation improves skin moisture, elasticity, and reduces wrinkles. It stimulates collagen production, helping to restore firmness and slow the visible signs of aging678.
- Soothing and Healing: Omega-7’s anti-inflammatory properties make it valuable for soothing sensitive or irritated skin, and it supports wound healing. It has shown benefits for conditions like eczema, acne, rosacea, and burns68.
- Mucous Membrane Health: It also hydrates mucous membranes (eyes, mouth, vaginal tissue), relieving dryness and discomfort
Omega-7 for Heart and Vessel Health
- Cholesterol and Lipid Profile: Research indicates Omega-7 can help lower total and LDL (“bad”) cholesterol, triglycerides, and C-reactive protein, while increasing HDL (“good”) cholesterol1346. This supports overall cardiovascular health and may reduce the risk of atherosclerosis.
- Anti-Inflammatory Action: By deactivating proteins responsible for inflammation, Omega-7 helps protect blood vessels from chronic inflammation-a key factor in heart disease26.
- Metabolic Benefits: Omega-7 improves insulin sensitivity and helps prevent insulin resistance linked to obesity and metabolic syndrome, further supporting vascular health
Potential Brain and Nerve Benefits
- Vascular Support: While research is still emerging, Omega-7’s positive effects on blood vessel health may extend to cerebral circulation, supporting brain vessel integrity and potentially cognitive health3.
- Anti-Inflammatory and Antioxidant Effects: The anti-inflammatory and antioxidant properties of Omega-7 may help protect neural tissue from oxidative stress and inflammation, both of which are implicated in neurodegenerative diseases
How to Add Plant Omega-7 to Your Diet
- Best Sources: Sea buckthorn oil is the most concentrated plant source, followed by macadamia nuts and avocado346. Supplements made from sea buckthorn are widely available and often combined with other beneficial nutrients.
- Dosage and Safety: While there is no official recommended daily intake, studies typically use doses ranging from 220 mg to 500 mg per day. Omega-7 is generally well-tolerated, but as with any supplement, consult a healthcare professional before starting, especially if you have underlying health conditions or take medications.
Conclusion
Plant-based Omega-7 is a promising nutrient for those seeking to improve skin hydration and resilience, support heart and vessel health, and potentially protect brain function. Its unique ability to hydrate, regenerate, and protect makes it a valuable addition to a balanced diet, whether through whole foods or high-quality supplements.
For radiant skin, a healthy heart, and resilient vessels, consider making plant Omega-7 part of your wellness routine.
Always consult your healthcare provider before starting new supplements, especially if you have pre-existing conditions or are pregnant or breastfeeding.
